Evaluation of Tillage, Nitrogen Fertilizer and Crop Residue Management on some Agronomic Traits of Soybean
This study setout to investigate the effect of wheat residue, tillage, and nitrogen fertilizer management on some agronomic traits of soybean as a split split plot based on randomized complete block design with three replications. The main plots included wheat residue management: collecting and leaving residue and sub plot included tillage (without tillage and conventional tillage), and the sub...
متن کاملTillage management to mitigate herbicide loss in runoff under simulated rainfall conditions.
Conservation tillage mitigates soil loss in cropland because plant residues help protect the soil, but effects on pesticide movement in surface runoff are not as straightforward. Effects of soil disturbance on surface runoff loss of chlorimuron and alachlor were evaluated utilizing runoff trays. Soil in the trays was either disturbed (tilled) and kept bare or was not tilled, and existing decomp...
متن کاملDevelopment of a simple, catchment-scale, rainfall- evapotranspiration-runoff model
Representation of the hydrological interaction between the land surface and the atmosphere requires considerable improvement, particularly for predicting evapotranspiration feedbacks for use in models of the general circulation (GCMs) of the atmosphere. The predictive model developed here attempts to use a water balance approach that extracts information from the masses of catchment-scale time ...
متن کاملCrop 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 کاملRemote sensing of crop residue cover and soil tillage intensity
Management of plant litter or crop residues in agricultural fields is an important consideration for reducing soil erosion and increasing soil organic C. Current methods of quantifying crop residue cover are inadequate for characterizing the spatial variability of residue cover within fields or across large regions. Our objectives were to evaluate several spectral indices for measuring crop res...
