Effect of Tillage and Nitrogen Rate on Corn Yield and Nitrogen and Phosphorus Uptake in a Corn-Soybean Rotation
Understanding tillage, N, and P interactions can contribute to improved N and P utilization and crop response. This study examined the interaction effects of tillage and N rate of two N sources on N and P uptake by corn (Zea mays L.). The study was conducted on Kenyon loam (fine loamy, mixed, mesic Typic Hapludolls) soil at the Iowa State University Northeast Research and Demonstration Farm nea...
متن کاملTillage and Fertilizer Placement for the Corn-soybean Rotation
The information presented is part of ongoing research to identify effective conservation tillage systems and phosphorus (P) and potassium (K) fertilizer placements for corn and soybeans. The rate of adoption of the no-till system by Iowa producers has decreased after a marked increase during the late 80s and early 90s. Actually, the area of no-till corn has decreased slightly since 1994. Severa...
متن کاملCorn and Soybean Yield Response to Tillage, Rotation, and Nematicide Seed Treatment
Corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] rotations are common production systems across the midwestern United States. However, the interactive effect of crop rotation, tillage, and nematicide seed treatments on the yield of both crops in the rotation system is not well understood. Field trials were conducted in a long-term crop rotation experiment during 2013 to 2015 to measure y...
متن کاملMicrobial community responses to soil tillage and crop rotation in a corn/soybean agroecosystem
The acreage planted in corn and soybean crops is vast, and these crops contribute substantially to the world economy. The agricultural practices employed for farming these crops have major effects on ecosystem health at a worldwide scale. The microbial communities living in agricultural soils significantly contribute to nutrient uptake and cycling and can have both positive and negative impacts...
متن کاملTillage and crop residue effects on soil carbon and carbon dioxide emission in corn-soybean rotations.
Soil C change and CO2 emission due to different tillage systems need to be evaluated to encourage the adoption of conservation practices to sustain soil productivity and protect the environment. We hypothesize that soil C storage and CO2 emission respond to conservation tillage differently from conventional tillage because of their differential effects on soil properties. This study was conduct...
