1. Impact of Phosphorus Source and Timing on Corn Yield and Root GrowthPhosphorus (P) management is critical in maize production due to limited mobility, solubility, and stratification in soils. This study evaluates P application techniques with regard to maize grain yield, total P uptake, and root distribution. Our hypothesis was that applying P as a side dress in a low P soil at a low dose equal to plant uptake can compensate for not maintaining soil test P at the critical level, providing sufficient P during peak demand and sustaining high yields. A greenhouse... A. Beltrame, C. Penn, D. Quinn, M. Williams, C. Zhang |
2. Interpreting Soil Health Test Results to Guide Management for Missouri Row CropsSoil health determines long‑term productivity, nutrient cycling, water retention, and resilience in row‑crop systems. Missouri-specific, data-driven framework for interpreting six complementary soil health indicators—total organic carbon (TOC), permanganate-oxidizable carbon (POXC), 3-day soil respiration, wet aggregate stability (WAS), autoclaved citrate-extractable (ACE) protein, and potentially mineralizable nitrogen (PMN)—was developed by the University of Missouri Soil Health...
