What is no-till?
No-till is a system in which the soil is not disturbed before planting except for injecting fertilizer nutrients such as liquid manure or anhydrous ammonia. A double-disk opener creates a seed furrow for planting. Tillage is entirely eliminated. Residue from the previous crop remains on the soil's surface to protect it from erosion.
Economics, money saving (less equipment, fuel and labor). Soil conservation, erosion control. Increased soil health/organic matter. No-till increases soil organic matter, which helps to stabilize the soil. Water infiltration and soil porosity are improved and surface crusting is reduced.
Set up and adjustment of the planter closing system to the rear of the seed opener and any front-mounted attachment (such as row cleaners) depends on the planter frame being leveled for field operation.
Although specific brands of agricultural equipment are shown in this video, the Iowa Learning Farm does not intentionally promote manufacturers. The ILF promotes the conservation farming practice that the equipment in this video is manufactured to accomplish.
