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...
Drip irrigation is often considered a technological solution to increase water use efficiency and crop productivity. However, all too often, its social institutional entanglements are ignored. This paper treats drip as socio-material assemblage discusses the changes triggered by introduction of infrastructure in A?lasun, rural town located southwest Turkey. Through an ethnographic study, we inv...
The semiarid is characterized by extreme heat, which affects agricultural production limiting the soil's ability to retain water. objective of this study was investigate influence mulch on soil temperature and moisture in a drip irrigated banana plantation Brazilian region. Six thermocouples three probes were used, with coconut coir as mulch. Daytime nighttime surface temperatures compared for ...
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...
