Article Synopsis
- The study investigates corn biomass accumulation and nutrient uptake during the V6 growth stage, highlighting the importance of synchronizing nutrient supply with crop demand to minimize nutrient loss and improve efficiency.* -
- Corn recovery from early nutrient stress, where no fertilizer was applied initially, was assessed under varying soil moisture levels using different irrigation systems, revealing significant reductions in biomass and nutrient uptake.* -
- Results showed that early nutrient stress led to yield reductions between 1.58 to 3.4 Mg/ha, with more severe impacts (37.6-38.2% reduction) under subsurface drip irrigation due to water stress in topsoil.*
Growers rely on nutrient sufficiency ranges (NSRs) after plant tissue analysis to inform timely nutrient management decisions. The NSRs are typically established from survey studies across multiple locations, which could be confounded by several abiotic and biotic factors. We conducted field studies in 2020, 2021, and 2022 to validate the lower thresholds of the NSRs for corn () at the early growth stage as reported in the Southern Cooperative Series Bulletin #394.
