A 31 year record of ∼44,000 nitrate analyses in ∼11,500 irrigation wells was utilized to depict the decadal expansion of groundwater nitrate contamination (N ≥ 10 mg/L) in the irrigated corn-growing areas of eastern and central Nebraska and analyze long-term nitrate concentration trends in 17 management areas (MAs) subject to N fertilizer and budgeting requirements. The 1.3 M contaminated hecta...

Long-term Yellow River irrigation and the unique natural conditions in the Heitao Irrigation District (HID) Inner Mongolia, China, has led to serious environmental problems such as the shallower groundwater table and soil secondary salinization, etc. The conflicts among socio-economic development, water shortage and environmental degradation have become increasingly critical. By using the stati...

This article presents the results of long-term theoretical experimental field studies on drip irrigation Apple orchard cultivar “Golden” in conditions Tashkent region. Based analysis climate, soil, hydrogeological, hydrological and economic plot biological features garden is determined by values total water use, scarcity water, irrigation, norms number irrigations bioclimatic method.

In this research, amount of evaporation and transpiration and water requirement of wheat plant for Marvdasht town (representation station: Zaraghan) during 17-years statistical duration from 1989-2005 and properties of plant and soil are calculated using CROPWAT software. At the first, trends of dry and wet periods for mentioned station were determined using long-term average of climatic data (...

The North China Plain is one of the most important grain production regions in China, but is facing serious water shortages. To achieve a balance between water use and the need for food self-sufficiency, new water efficient irrigation strategies need to be developed that balance water use with farmer net return. The Crop Environment Resource Synthesis Wheat (CERES-Wheat model) was calibrated an...

Use of wastewater for irrigation has become indispensable worldwide due to accelerating water scarcity, and it also carries a social dimension of poverty reduction in developing countries. However, the impacts of wastewater irrigation on soil properties are still insufficiently understood, especially with regard to change in soil microbial community characteristics. The present study presents a...
