1. Cover Crop Function and Management Optimization for Semiarid West Texas Cropping SystemsWater-use is a primary concern preventing integration of cover crops in dry climates. Recent research has demonstrated that adequate cover crop residue (with optimal termination timing) is more likely to improve soil water dynamics for the subsequent crop. Regarding cover crop function in West Texas, wheat stubbles as a fallow may offer a cheap and effective solution to prevent wind erosion and facilitate water storage in soil profile. Optimum management practices are likely different though... T. Hussain, R. Noland, R. Matschek, . Delaune, E. Kimura , J. Muir |
2. Carbon & Nitrogen Transformation in Soil After Biosolids or Inorganic Fertilizer ApplicationBiosolids are nutrient rich organic residues which could be a potential alternative to conventional fertilizers. However, their C and N mineralization rates vary depending on treatment processes and soil properties. A laboratory incubation was carried out to evaluate C and N dynamics in contrasting soils by quantifying gaseous losses and assessing N transformations between organic and inorganic pools. Soils collected from Texas (sandy clay loam, pH: 8.4) and Florida (sandy loam, pH: 7.6) were... S. Bhatta, L. Slaughter, M. Siebecker, J. Adjei, K. Lewis, O. Gecgel, C. Alvarez-pugliese, K.
