Fertilizer Placement And Tillage Interaction In Corn And Soybean Production, A. T. Rosa, D. A. Ruiz Diaz
Kansas Agricultural Experiment Station Research Reports
Different tillage systems can affect the availability of phosphorus (P) by changing the soil environment. The objective of this study was to evaluate the effects and interaction of fertilizer placement, tillage, and varieties for soybean and corn. The experiment was established at two locations in Kansas in 2014. The experimental design was a factorial in a randomized complete block with four replications. Three fertilizer treatments were combined with two tillage systems and two varieties of soybean and corn selected based on contrasting root systems. Plant tissue samples were collected during the vegetative and reproductive stages to evaluate P concentration, P …

In 2013, late planting resulted in corn yields that were less than 110 bu/a. Yields were not increased with seeding rates above 26,000/a, but a small increase in yield was obtained with knife applications of fertilizer nitrogen (N) compared with dribble.
