Crop Residue Decomposition in No-Tillage Small-Grain Fields
wind erosion. Soil microenvironments are different in fields that have surface-crop residues than in tilled fields Conservation tillage fields provide different environments for biowith incorporated residues. Natural-resource simulation logical and chemical processes than tilled fields. Our understanding of decomposition does not adequately account for post-harvest residue models that address s...
متن کاملAtrazine leaching from biochar-amended soils.
The herbicide atrazine is used extensively throughout the United States, and is a widespread groundwater and surface water contaminant. Biochar has been shown to strongly sorb organic compounds and could be used to reduce atrazine leaching. We used lab and field experiments to determine biochar impacts on atrazine leaching under increasingly heterogeneous soil conditions. Application of pine ch...
متن کاملEstimating Crop Residue Decomposition Coefficients Using Substrate-induced Respiration
-hlodeling of crop residue decomposition for nutrient cycling and effectiveness of residues to control soil erosion requires information on crop-specific decomposition coefficients (k). Respiration of decomposing residues reflects the activity of the microbial community and should give an indication of the residue decomposition rate. A method for estimating k using substrate-induced respiration...
متن کاملLarge-Scale Biochar Production from Crop Residue: A New Idea and the Biogas-Energy Pyrolysis System
Biochar is an effective means to withdraw carbon dioxide (CO2) from the atmosphere and consequently influence the trend of global climate change. However, there still are substantial knowledge gaps for this idea to be applicable. One big question is how to produce biochar from biomass on a large scale. Our idea is to use biogas produced from agricultural wastes as thermal energy for biochar pro...
