 Welcome to our video training. This is Eric, conservation agronomist. This is March 27th, 2019, and we're going to go through Mark Washchek and I are going to go through some of the new changes or updates to the 590 standard. We're going to go over our 590 specification guide. We're going to go over a new spreadsheet to help document nutrient applications. We're going to show you where to find these documents, and we'll do that first of all here, so Mark will open up. We need to find these on you can just Google field office tech guide that will take you to maybe maybe Mark can just go along and show you how it goes. It's going to get you to our NRCS field office tech guide. There you go. Yep, then we're going to choose our state. There's field office tech guide. Yep, click that one. I'm going to choose South Dakota. Submit. Section 4 is where conservation practices are, and we're the third one down is conservation practices. This is all stored under the nutrient management. They're in alphabetical order, so you just passed it. Go back up to N, and then we have a few different things under nutrient management. We have the specification guide that we're going to be going over. We've got the documentation requirements. We've got the job sheet CPA 8. That's for manure management stuff. Then we have a statement of work. We have the nutrient management standard, and then we have the job sheet 590, which is what we're going to be demoing today for commercial fertilizer applications. Variable rate or flat rate commercial fertilizer. So with that, I will have Mark open the specification guide. We have it minimized at the bottom there. So here's a few of the updates from the 590 standard that was on eFOTOG there. That's about a 12-page document, a lot of manure management stuff, a lot of commercial fertilizer stuff all mixed together. So a committee was put together and we kind of sorted out the the commercial fertilizer stuff, and that's the heading of this document here. So it's broke down into a few different categories. We have soil testing at first, yield goals later on. Then we have nitrogen, phosphorus, potassium, and how we're going to certify that this practice of 590 has been met. So we're going to go through this document, explain each one of these steps to you. So starting with soil testing, there's basically three ways agronomists or producers are soil testing for 590. They're either doing a flat rate application of nutrients and their composite soil testing of the whole field, or they're setting up management zones and soil sampling by zone, or they're setting up grids and soil sampling by grid. So it's pretty common for composite and zone samples to do a 0 to 6 and a 6 to 24 inch sample for N, P, and K. In the case of grid sampling, it's commonly done only on a 0 to 6 basis, and that's okay for P and K in that initial year. When we need to calculate the rate of nitrogen without having that 6 to 24 inch soil test, our specification guide says to use 40 pounds in lieu of that 6 to 24 inch soil test. When we get later on in our presentation today, we're going to show you a spreadsheet and how that 40 pounds is carried over into that spreadsheet. But for now, when it comes to soil testing, we're going to use 40 pounds on that initial year of grid sampling. When it comes back to your next nitrogen requiring crop, that's when we're going to ask that a 6 to 24 inch sample will be taken. So that'll be according to the EC 750 from SDSU. And that 6 to 24 inch can be taken then either by management zones, field composite, yield maps, or other method recognized by SDSU. So that's a little bit about soil testing. Yield goals, all the recommendations in South Dakota are still based on yield goals, so that's a huge part of this whole recommendations process. So it's very important we get that part right. It's pretty easy when we got a field composite flat rate application, we can take our three consecutive years and average those. There's some maybe South Dakota ag statistics yields we can use. But in the case of grids or zones, that becomes a little bit more challenging to get yield by management zone. So we're going to rely on the producers to use their best judgment and get realistic yield goals so that this whole process works correctly. So nitrogen management, we'd like you to use the SDSU EC 750 formula, which for an example here, they have one of these for each nitrogen requiring crop. For corn, we have 1.2 times our yield goal and then subtract off our appropriate credits. That has not changed. That's still the same process we've always had. They did add a little bit of a buffer or a tolerance level in there. If for some reason we deviate from that exact formula a little bit, there's a 30 pound tolerance level for nitrogen. Maybe if you used an efficiency factor, maybe an organic matter credit, maybe you weren't able to variable rate starter. For some reason that your formula changed a little bit. You have a 30 pound tolerance within that. Number eight on this guide, high leaching fields, that's the same as it's always been. Just no commercial fertilizer nitrogen basically fall applied or no more than 45 days prior to planting. If there's incidental nitrogen like in a DAP or a MAP phosphorus product, that's okay to be applied more outside that 45 day window. So that's nitrogen phosphorus similar to nitrogen. We have a formula that we use for every crop to calculate the rate of phosphorus. If for some reason we need to deviate from that exact formula for agronomic reasons, then there's a 30 pound buffer also or tolerance associated with phosphorus as well. One other slightly different tweak that's been done. If the exact formula for phosphorus calculates a zero rate, which a lot of times on the Olsen scale, that's about 15 to 16 parts per million Olsen for depending on the crop, that's going to calculate a zero rate. But if we still want to apply a little bit of phosphorus, then we can use crop removal portion in the grain of the crop you're growing up to 25 parts per million Olsen or 35 parts per million on the Bray 1 scale. So a little bit of leeway in there to to build soil test phosphorus just a little bit. If you want to know what those crop removal rates are, they're in the SDSU publication EXEX8009. It's okay to do a two-year spread. Typically I see this done for corn and beans. If you want to apply a little extra during the corn year for the following bean year, that is what I'm talking about. It's a two-year spread and that's okay. Just as long as we're less than that 25 parts per million Olsen and 35 Bray again, then we'll add those two numbers together. That 30 pound tolerance or buffer that I mentioned, that does kind of have a cap on it. That's not allowed after we reach really high soil test phosphorus levels. That being 76 Olsen or 101 Bray on the Bray 1 scale. That's when no tolerance, no buffer is allowed anymore. Basically just a complete zero application for those high soil testing fields or zones. So I think that should cover phosphorus potassium. We're gonna follow again those same lines. We're gonna start with our exact formula for the crop we're growing. If we do get a zero calculation, we can apply crop removal in the grain up to 200 parts per million on the soil test, whichever is greater. There is a buffer or tolerance for potassium as well and that's a number 19 and that's a hundred pounds. That's a little bit higher than what nitrogen and phosphorus were. It's a hundred pound tolerance for potassium. Again, we can do the two-year spread for P and K. So same thing. We're just gonna add the two together. Same thing we did for phosphorus. Now when it comes to certifying this practice, that's really important. We just gotta make sure that we're covering the fields that are planned or scheduled to have nutrient management applied. So that's step number one. Make sure we have the correct fields we're doing and then depending on what part of the practice or enhancement we're doing, we need to show that appropriately. So we need to email those documents. Typically going to be an application map of some kind, a soil test or in the flat rate fields. We can just apply email an FSA map or plan map would work. When it comes to these variable rate fields or the math associated with calculating the rate, that's when this spreadsheet that we're going to demonstrate next needs to be completed. We need to complete this spreadsheet for two fields for each of the crops fertilized. So two corn fields that receive fertilizer, two bean fields, two wheat fields. For whatever crops you're growing that receive fertilizer, we need to fill this spreadsheet out for two of those fields. So not all the fields in the plan, but at least two per crop fertilized. So that's what we're we're gonna go over. There's a few things about the spreadsheet that I'd like to show and talk to you about once we get to the spreadsheet. So with that I guess there's a couple comments down here. If for any fields that receive manure application, we still want to use the CPA8 or the CPA63. The CPA8 is pretty short, concise and simple. I think you can you can calculate rates for about five or six fields at once. If you need more fields than that or if you want to do some zones or something with manure, then we we definitely need the CPA63. So that's the difference in those two forms. The same math will be calculated for both in both forms and then for fields that receive commercial fertilizer only then this this job sheet 590 that we're going to demo next is definitely the one that you'll want to use. So all these forms and this whole process is all found through SDSU publications. How you soil test 0 to 6, 6 to 24 that can be clearly explained in this the SDSU FS935. The fertilizer calculations all came from the EC750 and the crop removal numbers came from the quantities of plant nutrients contained in crops EX8009 all SDSU publications. So with that mark should we open the spreadsheet maybe I'll have you give a give a introduction to the layout of the spreadsheet and kind of some housekeeping documents. Yeah thanks Eric. Before we open it I thought I'd just cover a couple points. Let you know that the spreadsheet it was designed specifically for the purpose of collecting and storing this information from the producer or consultant by the zone the grid or the grid for up to 15 fields in an operation. The information that we're collecting includes the producer's name the field number grid number zone number soil test crops grown yield goals fertilizer products applied and the amount supplied. The spreadsheet can calculate also a recommendation of N P205 and K20 based on land-grant university recommendations specifically the South Dakota State University method like Eric said earlier using the EC750. The limit the spreadsheet has limits and the limits are up to 15 fields will fit in the spreadsheet and we can go up to 17 zones or grids and that typically will be plenty of zones grids we're gonna run out of space but we're gonna have you fill in the first 17 and and we'll be able to evaluate what was applied from there. The spreadsheet has a couple tools built in the user can build custom blends as part of the application documentation so if we don't have a particular blend in the list then you can build your own let you build a couple of them. The spreadsheet can also be used as a playing tool to to look at what would be recommended by the EC750 for the particular crop yield goal and so on so that's a pretty handy feature I think. It also checks the data as you enter your information if there's additional data that it needs it will ask you for that if you use a two-year calculation for example the spreadsheet automatically sends you to the second year page and as you enter the crop and yield goals. So I think with that we can I'll send it back to Eric here and we can take a look at that spreadsheet and get into the details of it. Yeah great thank you so we'll have Mark open up a spreadsheet there's basically two ways this can be done we can use it as a documentation tool and so Mark's gonna open up a spreadsheet that we're gonna say was emailed back to the NRCS office so so him or I as an NRCS employee you're gonna be able to take a look and see what crop was grown yield goal was placed what fertilizer was applied see if we are following the rules or the guidelines that were explained in that in that specification guide so we can do that we're gonna first agree to the disclaimer we're gonna read through that carefully we're gonna agree to it click to continue so this would be how we could see this form being completed by a producer or agronomist at the top they got the name the field ID the crop year that was grown the crop that was planted that's all from a drop-down list if it was a no-till field or not that would be indicated by you yes or no if it's left to blank we're considering it no same thing with the two-year calculation if it was a two-year or spread or not so as I'm going through that heading part maybe now would be a good time to explain there's on the left-hand side there's a lot of buttons I guess over there and they're pretty helpful pretty handy so this print button I'd encourage you to get in the habit of using that for a couple different reasons that's only gonna print the fields that have data in them and like Mark said the spreadsheet has 15 fields as you scroll to the right so all these blank pages won't print if you just go for oh yeah only with the fields field ID is filled out that's where we'll get data to print if you just go up to file and print you're gonna get all 15 pages so if you only want the pages with data just use that print button the video that's being recorded today will be stored in this video link tab at the bottom and you'll be broke down into a different segment so you don't don't have to watch the whole video to see the part that you're interested in so that'll be on there this check crop names we're gonna demonstrate how that works but basically what that's doing is if you copy and paste your soil test information here from a soil testing lab it's gonna make sure that the previous crop name is named that the programmer the spreadsheet can understand it and give the appropriate legume credits so it's important to make sure that we check those crop names if we're copying and pasting fields in here soil test values in here so we'll do that if you scroll down just a little bit mark there's a add custom blends button in blue there that's gonna be really handy when we come to showing the applied fertilizer and that okay there's this other button down here the show recommendations we're gonna show how that button operates to here in a little bit so those are our buttons and kind of the layout of the spreadsheet like Mark said there's 17 zone or grid points as you scroll down there and there's 15 fields as you scroll across so that's the limits of the spreadsheet is is that so typically we you know if you're doing a field composite or flat rate you obviously just have one line to fill out on your field and if you're doing zones you'll complete however many zones are in that field I've seen anywhere from 3 to maybe 7 9 zones depending on the variability the field and and the people doing the work for grids it's commonly done in two and a half acres per grid but we're only going to take the top 17 just started grid point number one and and complete 17 in a row that's all the data we're gonna ask for I've would encourage you if you are doing grids to have this spreadsheet opened up at the time that the grids are developed and the prescriptions are wrote and all this data that it's asking for here in the applied section will be right on your screen and you can copy and paste it right in here if you come back say today and look at some grids that were developed last fall it's gonna be a lot more challenging to get that data a nutrient supplied per grid point so with that we're gonna show you what this agronomist or producer provided us as documentation for 590 standard so they had four zones in there previous crop with soybeans date the soil samples were taken number of acres per zone soil tests for 0 to 6 and 6 to 24 since our crop that is being grown is corn we need a 6 to 24 inch for a nitrogen requiring crop our soil test phosphorus levels we're both in the Olsen and the Bray scale so those are in the appropriate columns and the potassium is over there on the right hand side so that's our soil test as we scroll down just a little bit you'll see the yield goals is very important to have that put in there and then the products that were applied and the dates that those applications were made so this producer used urea as a nitrogen source pre-plant along with some potassium and some kind of a homemade mes product with some nitrogen phosphorus sulfur and zinc we did not keep track of the sulfur and zinc were the spreadsheets only gonna track the three major nutrients NP and K so that's all you guys need to keep track of is NP and K so they did they did those three applications early before the corn is planted they did 28% they did 1034 oh with the planter 5 gallons of 1034 oh and then they came back and applied 10 gallons of 28% with the pre-emerge herbicide so those were the nutrient applications that were made now if we want to see how close those balance with the SDSU EC 750 there's a tab at the bottom you just click simply click that button or that tab down there and it's laid out with nitrogen first it's got your your zones your yield goals previous crops gives you the appropriate credits your soil test credits if there was no till it add 30 pounds to the nitrogen recommendation it gives you then the recommendation what was actually applied to this field and then are you plus or minus that recommendation so we came out perfectly in balance on our nitrogen phosphorus potassium or the next two right below that same thing we have our soil test we have our recommendation and then we have our new nutrients applied our phosphorus applied and you notice there that zones one and three the first two rows on there are 20 pounds higher than what was recommended and basically because our soil test values that 30 and 22 on the Olsen scale came up to a zero recommendation but we still put on five gallons of 10 34 oh so we applied 20 pounds of phosphorus and that's the reason if you remember when I said there was a 30 pound tolerance when we were talking about the specification guide so that 20 pounds of starter fits well within our 30 pound tolerance so that works pretty good the balance if you if you need to know more explanation about what that balance is there's a little red triangle in the corner that cell hover your mouse over it and that explanation will pop up and then you can read that so anytime you see those red triangles throughout the spreadsheet that's more information that you can read about so same thing with potassium we had some different soil test values a couple zones called for zero a couple zones called for some nutrients we put on exactly what was recommended so we're perfectly in balance there so there's one mother thing I want to point out in this this field before we do a second field example and that would be on zone three the second row of this spreadsheet you notice there's a zero recommendation for P and K and and our soil test value for P is 22 Olsen and for K it's 192 and so those would still be below our kind of our cap for crop removal so we could apply crop removal on that zone if we wanted to or we could on the the zones below that as well and to get the crop removal numbers there's a there's a tab at the bottom simply called crop removal if we click over there they'll give us the P and K for crop removal so you notice on that same spreadsheet line now we're instead of over applying 20 pounds like we did through our starter now we're actually 45 pounds short if we're going crop removal rates and same thing with potassium we need another 53 pounds if we want to put on crop removal and again you can do that up to 25 parts per million bray no 25 Olsen 35 bray or 200 on the potassium that's when crop removal can't be used anymore once you reach those numbers so hopefully that gives a little leeway to do what we need to do on a field-by-field basis anything else I forgot to mention there mark before we skip to the next field no I think you did a really good job explaining that and the fact that these comment boxes are all over the spreadsheet I would encourage people to take advantage of taking a look at some of the instructions clarifications lots of tips so use that all right let's go to an example the next way this spreadsheet can be used let's use it as a planning tool so let's figure out how many pounds of nutrients we want to put on now we're going to show you how to import soil test values into the spreadsheet so we're going to open the spreadsheet then we're going to open a excel file with the soil test values and we're going to show you how to copy and paste those in there to save save time from having to type all that information so so open that spreadsheet with their soil test values and so we're going to copy and paste exactly the number of columns that we need we're leaving off the field ID column because we don't need that in the spreadsheet so he's going to copy and paste values it's very important that we paste values in there we're going to enter the crop to be grown will be corn we're going to show you that it's our producer name we're going to enter a field ID and then we're going to enter the oops then we're going to enter the year that this crop will be grown and we're going to say we're going to grow this in 2019 and if you want no till or not that just adds 30 pounds to the nitrogen credit but we're going to show you a two-year spread so we're going to click yes there if you leave it blank it's considered no so we can we can do it two ways we can do it an hour or later I guess we didn't we got to check our crop names or previous crop column there didn't match exactly so the spreadsheet caught that and it's going to ask us to correct that so we get the appropriate legume credits first it'll take us first it'll take us into the second year okay where we need to enter in the yellow cells a yield goal for the zones for our second-year crop which we're going to go soybeans correct you'll go scores are 40 50 and 60 in this example and it's very important we get a realistic yield goal for the field we're working on obviously but for example that's what we're using today or click done the fact that it told us we got a problem with crop names it hasn't fixed it yet okay so I think we better just go fix it by clicking crop names soy bean is the problem takes us to soy bean here and we have to call it soy beans in this spreadsheet we'll say okay and that even though it doesn't change it here it's fixed to the point it can make the correct calculations so now we're getting the appropriate credits legume credits for our previous crop so we have our soil test values entered in there now let's figure out the nutrients we want to put on for our two-year spread so our our yield goal for a corn crop is going to be 150 175 and 200 and the products we're just going to pick three products we're going to do a phosphorus source like map or DAP so like a 1050 or 1150 yep they'll be our phosphorus source then our our potassium 0060 and then we're going to show you how to do a custom blend for say a urea AMS blend so we can we can choose our custom blend and it's going to be a dry blend and we're going to use like a 75 25 ratio so 0.397 will be the nitrogen we'll leave the the phosphorus potassium blank we don't have any of those nutrients in there and the sulfur part we don't need to be concerned with just the NPK so we can click done for a custom blend and then we need to choose our custom blend option there so that's way at the bottom of the drop-down list custom blend one and that shows us our percent nitrogen in that blend and then we're going to need to figure out how many pounds of each of these products to apply so we can simply scroll down show the recommendations button there in the left and we can start to complete that starting with our phosphorus source we'll choose p205 we can either type those in or copy and paste them up above and when we do copy we obviously paste values to make sure we're doing that correctly we can go down get our potassium source switch that to K20 0 100 0 yes this will be for our two-year spread so it's add it's doing the math to calculate up what the soybeans need with those yield goals we entered plus what the corn needs for for this year so there's the nitrogen and we can we can double-check what we put on there under the SDSU EC 750 tab that gives us our recommendations our application rate new producer applied and then the balance to make sure that those balance perfectly and down below on the P and K that'll be the combination of the corn and the soybeans applied on there so what we needed and what we applied and they're both in balance crop removal tab as long as we're below 25 parts for million Olsen 35 on the brayscale if we so desire we could do crop removal or the EC 750 formula whichever is greater and so you'll see now that we there's additional nutrients needed if we wanted to do the full crop removal and it shows us how many pounds of nutrients there for both P and K we'd have to go ahead and do the math to figure out how many pounds of product we needed to put on and then go back to that field data tab and enter those appropriate pounds of products in there that'll do it that concludes our copy and paste soil test data demonstration
