Can no-till work in all types of soils?
While it is generally possible to produce a crop by using no-tillage on any field, maximum returns will normally be achieved by matching the proper tillage system to the soil type. Our experience with no-till agriculture has shown that no-till works best on soils that have relatively good drainage. On soils with relatively poor drainage, corn has been successfully grown without tillage if the corn follows soybeans in a crop rotation. Corn following corn has proven to be unsatisfactory on untitled, wet soils. 2. Should P and K be incorporated in some way with no-till? Immobile nutrients like P and K are most efficiently taken up if they are placed in moist soils where roots are actively feeding. Under high residue conditions, it is difficult to measure a yield advantage from incorporation of nutrients. Under low residue situations, however, research has shown that it is important to place immobile nutrients into the soil to insure uptake. We have found that a band placement, below and t
