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...
To design cost-effective and efficient drip irrigation systems, it is necessary to know the vertical and horizontal advance of the wetting front under the point source; also, the proper management of drip irrigation systems requires an awareness of the soil water distribution. Many factors influence wetting pattern dimensions, including discharge, land slope, irrigation time and soil texture. T...
Abstract The authors have designed a seed pelleter and combined precision sowing rig, which are the backbone of technology pre-sowing treatment sowing. method is based on operation continuous pelleter, where protective nutritious coating formed around seeds while they move along spiral trajectory. next component rig that performs several technological operations in one pass: laying drip tape fo...
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...
