Managing Phosphorus and Potassium Is Key in Conservation Tillage Systems

Abstract

AbstractMore and more, North American farms are moving toward conservation tillage practices, including no‐till and strip‐till. With this trend has come a lot of questions about how best to apply fertilizers, especially phosphorus and potassium, in conservation tillage. In a recent study, researchers examined how yield and root growth in corn and soybean crops are affected by tillage, fertilizer application rates, and fertilizer placement. The team also looked at nutrient use efficiencies and soil phosphorus and potassium levels. The findings echo the results of previous studies and provide a baseline for best practice recommendations.
