Purpose: to determine dependencies and develop a methodology for calculating the geometric dimensions constructing outline of local moisture contours formed in soil space during drip irrigation. Materials methods. The factual basis development was data full-scale (field) measurements drip-moistened their office processing. studies were carried out on experimental sites with different cover, rep...

Low permeability tarps can effectively minimize fumigant emissions while improving fumigation efficacy by retaining fumigants under the tarp. However, when planting holes are cut through the tarps, high-concentration fumigants may be released and result in environmental and worker safety hazards. In a 11-day column study, we explored the effect of drip irrigation application of ammonium thiosul...

In recent decades, plastic-mulched farmland has expanded rapidly in China as well as in the rest of the world because it results in marked increases of crop production. However, plastic-mulched farmland significantly influences the environment and has so far been inadequately investigated. Accurately monitoring and mapping plastic-mulched farmland is crucial for agricultural production, environ...

The replacement of flood-irrigation systems by drip-irrigation technology has been widely promoted with the aim a more sustainable use freshwater resources in irrigated agriculture. However, evidence for an irrigation efficiency paradox emphasizes need to improve our understanding impacts transformations on water resources. Here, we developed distributed hydrological modeling approach investiga...
