Kansas Agricultural Experiment Station Research Reports

Each Field Day report consists of individual research reports on topics specific to the region, including cultural methods for most of the major crops grown in Kansas, mitigating the effects of weeds, insects, and disease associated with those crops, and irrigation. Research is conducted and reports written by staff of the K-State Research and Extension Southwest Research Extension Center.


Soybean As A Receiver Crop For Nitrogen In Swine Lagood Effluent, Daniel W. Israel, Robert Mikkelsen Dec 2000

Soybean As A Receiver Crop For Nitrogen In Swine Lagood Effluent, Daniel W. Israel, Robert Mikkelsen

Robert Mikkelsen

Soybean (Glycine max L. Merr.) has been approved by the Natural Resource Conservation Service as a receiver crop for N in swine lagoon effluent applied to spray fields. However, its efficacy as a N receiver crop depends on the sensitivity of symbiotic N2 fixation to inhibition by N in the applied effluent. The objectives of this study were to use a 15N natural abundance method to (i) assess the degree of inhibition of symbiotic N2 fixation in soybean by applied effluent N and (ii) determine the quantity of effluent N removed from the soil in harvested seed of nodulating soybean. …
