Tillage and Nitrogen Placement Effects on Yields in a Short-Season Corn/Wheat/ Double-Crop Soybean Rotation

In 2016, adding nitrogen (N) greatly improved average wheat yields, but the response to tillage and different N placement methods was minimal. Double-crop soybean yields were unaffected by tillage or the residual from N treatments that were applied to the previous wheat crop.

Nitrogen, Phosphorus, and Potassium Fertilization for Newly Established Tall Fescue

Tall fescue production was studied during a third year at two locations. In 2015, Site 1 was affected by an interaction between nitrogen (N) and phosphorus (P) fertilization rates; while in 2016, Site 2 mainly received production differences by N fertilization rates. Potassium (K) fertilization caused little effect at both sites. Third-year production of tall fescue was affected by ...

Timing of Side-Dress Applications of N for Corn in Conventional and No-Till Systems

In general, conventional tillage averaged nearly 40 bu/acre greater corn yield than no-till likely because of improved growth during the season. With conventional tillage, all side-dress treatments resulted in greater yield than with all N applied pre-plant. However, in lower-yielding no-till systems, the yield response to side-dress applications appeared to be greater for V10 ...

Response of Soybean Grown on a Claypan Soil in Southeastern Kansas to the Residual of Different Plant Nutrient Sources and Tillage

The residual effects of turkey litter and fertilizer amendments applied in previous years had little effect on the yield, yield components, and dry matter production of the following soybean crop grown in 2014.

Surface Runoff Characteristics from Claypan Soil in Southeastern Kansas Receiving Different Plant Nutrient Sources and Tillage

Preliminary results show that two-year average total nitrogen (N) runoff losses and ortho-phosphorus (P) and total P runoff losses in the second year were greater with N-based turkey litter/no-till applications than P-based turkey litter or fertilizer-only applications. Incorporation of turkey litter applied based on N requirements resulted in N and P losses that did not differ ...
