1. Effect of Tillage, Rotation (Maize and Soybean), and Nitrogen Rate in a Long Term Study on Solvita, Water Extract, H3A Extract ValuesA long term rainfed tillage/rotation/N rate study was established in 1985 on a mostly Coleridge silty clay loam (fine-loamy, mixed, superactive, mesic Cumulic Haplustoll). The study is a factorial of plow, disk, and no-till under continuous corn (Zea mays) and corn following soybeans (Glycine Max) with five nitrogen rates (0, 40, 80, 120, 160 kg ha -1). Soil samples were taken from all rotation/tillage combinations and three N rates in the fall of 2013 to 0.20 m (8 in). They were analyzed using the... |
2. Versatility of Mycorrhizal Fungi Applications to Increase Maize ProductivityWith rising fertilizer prices and continual water contamination issues, it is vital to establish management factors that maximize productivity, while minimizing nutrient losses to the environment. One potential practice for improving nutrient use and grain yields includes utilizing mycorrhizal fungi. The objectives of this research were to determine the efficacy of various mycorrhiza applications on root colonization and the subsequent grain yield responses of maize (Zea mays... L. Woodward, F.
