On the territory of Uzbekistan, almost half area irrigated land is subject to salinization, for this reason up 30 % or more crop yield lost. With a shortage water resources, which will deepen due climate change, water-saving technologies must be used not only irrigation but also reclamation saline soils. The authors have developed new approach regulation salt regime and soil reclamation. conduc...

cultivated area, yield and production trend of wheat (triticum aestivum l.), barley (hordeum vulgare l.), potato (solanum tuberosum l.), alfalfa (medicago sativa l.) and chickpea (cicer arietinum l.) as the main crops of kurdistan province were studied during 1983-2006 using time series analysis and the situation of future were predicted for 2006-2021 period. the results showed that the cultiva...

Soil nitrate (NO3) tests are an integral part of nutrient management in annual crops. They help growers make field-specific nitrogen (N) fertilization decisions, use N more efficiently and, if necessary, comply with California’s Irrigated Lands Regulatory Program, which requires an N management plan and an estimate of soil NO3 from most growers. As NO3 is easily leached into deeper soil layers ...

Remote sensing and Geographic Information System (GIS) data can be used to identify larval mosquito habitats and predict species distribution and abundance across a landscape. An understanding of the landscape features that impact abundance and dispersal can then be applied operationally in mosquito control efforts to reduce the transmission of mosquito-borne pathogens. In an effort to better u...
