Project
description:
The objectives are 1) to quantify sorghum and mycorrhizae responses to pH stratification on sandy soils as a result of N application, and 2) to evaluate the effectiveness of liming application strategies in remediating soil pH stratification. Soil collected from farmers field having pH stratification in the top 30 cm are used to grow sorghum in the greenhouse. Additionally, the soil will are limed in three different strategies (no-till, reduced tillage, and conventional tillage). Root surface area, above ground plant biomass, mycorrhizal development, soil solution chemistry, and nutrient uptake of sorghum are being measured.
