1. An Evaluation of Nitrogen Application Methods for Ridge-Planted CornRidge planting is a conservation tillage method receiving some attention in the Midwest at the present time. In this system the crop is planted atop a ridge which was formed by cultivation of the previous year's crop. There is generally no tillage performed between ridge building and the next year's planting. The system is similar to no-till in that large quantities of residue are often present on the soil surface in the spring, most being concentrated in the ridge furrows. Research initiated in... |
2. Strip Tillage and No Tillage Fertilization Systems Evaluated for Eastern Kansas Rain Fed CornRow-crop agriculture in East-Central and Southeast Kansas is facing increasing pressure to reduce sediment and nutrient losses via runoff. Edge-of-field measurements show that no-tillage with fertilizers placed below the surface of the soil has significantly less sediment and total P losses in runoff compared to conventional tillage (Janssen et al., 2000). However, for rain-fed corn, no-tillage in these regions can provide serious challenges some years because of frequent spring rains and an abundance... |
