 Today I'm going to show you how to use the Acacor to take a Predictor V sample. This core is one centimetre in diameter and takes a 10 centimetre deep soil sample. The other things you'll need are a scraper, we use a flat handle screwdriver, gloves, a Predictor V bag that is pre-infilled out and an empty bucket. The way we're going to sample is on the row and through the stubble. You'll need to take three cores at 15 different locations throughout the paddock and for a total of 45 cores or roughly between four and five hundred grams. Take the core, grab the handles and push with the foot peg firmly. Give it a full twist. If you don't get a full core, scrape it out and start again. Full twist and full core. Once you've completed your three cores, it's time for us to sample the stubble. Take it from the base of the plant, break it off at the first node and add it to the bucket. Once you've completed your 45 soil cores and you've added your 15 pieces of stubble, it's time to put it into your pre-labeled bag. Close the bag, fold it over so the label can be seen, squeeze out any excess air, screw it with a rubber band and put it in the courier bag to be sent.
