1. Legacy Impacts of Cattle Grazing on Soil N2O and CH4 Fluxes in Shortgrass SteppeGrazing cattle directly emit CH4 from enteric fermentation and contribute to soil N gas emissions related to nitrogen and organic matter additions from urine and manure deposits. Grazed soils can be sources or sinks of CH4, depending on moisture levels and localized manure patches. N2O emissions are related to availability of water as well as mineral N and labile C substrates in soil. Previously, we observed higher N2O and NH3 losses from fresh patches of urine and manure compared to... S. Del grosso, J. Derner, J. Delgado |
2. Influence of Irrigation Timing and Amount on Cotton Physiology and Nutrient PartitioningThis study explores the impact of varying water levels on nutrient uptake in cotton plants, known for its sensitivity to environmental conditions. Recognizing the pivotal role of water availability in agricultural productivity, the experiment employed different irrigation scenarios and assessed the efficiency of nutrient absorption in cotton under these varied circumstances. The research also focused on analyzing nutrient content in different plant tissues,... K. Vargas, K. Lewis, J. Bicaldo, J. Burke |
3. 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.

4. Evaluation of E-Grow Effects on Soil Plant Systems Gas ExchangeE-Grow is a novel fertilizer which effect on the soil- plant system is critical for understanding it’s impact on the crop productivity and environmental sustainability in agricultural operations that will be crucial for updating nutrient application recommendations, to understand this we conducted an experiment with the main objective of this study is to determine the effect of E-Grow on CO2 and H2O fluxes in agricultural soil and soil- cotton plant systems (seedling stage). This experiment... V. Sabbineni, E. Enninful, S. Jacobo, O. Gecgel, G.G. Botte, H. Laza, C. Simpson, L. Slaughter, Y. Emendack |
