Impacts of manure application on soil environment, rainfall use efficiency and crop biomass under dryland farming
Because of inadequate nutrient and water supply, soils are often unproductive in Northwest China. We studied the effects of manure application at low (LM 7.5 t ha(-1)), medium (MM 15 t ha(-1)), and high (HM 22.5 t ha(-1)) rates combined with fixed levels of chemical fertilizers on maize growth and rainfall use efficiency compared with chemical fertilizers (CK) under semi-arid conditions over a...
متن کاملSoil properties affecting wheat yields following drilling-fluid application.
Oil and gas drilling operations use drilling fluids (mud) to lubricate the drill bit and stem, transport formation cuttings to the surface, and seal off porous geologic formations. Following completion of the well, waste drilling fluid is often applied to cropland. We studied potential changes in soil compaction as indicated by cone penetration resistance, pH, electrical conductivity (EC(e)), s...
متن کاملAssessment of productive efficiency for irrigated and dryland wheat farming in Iran using Data Envelopment Analysis
Wheat is widely grown in Iran as a staple food; therefore, the government there encourages farmers to produce wheat (a common agricultural enterprise) by increasing farm productivity and efficiency. The study compares the efficiency of wheat production for dryland (low input) and irrigated (high input) systems across Iranian provinces by using Data Envelopment Analysis (DEA). The average techni...
متن کاملSoil salinity and matric potential interaction on water use, water use efficiency and yield response factor of bean and wheat
We studied the effects of soil matric potential and salinity on the water use (WU), water use efficiency (WUE) and yield response factor (Ky), for wheat (Triticum aestivum cv. Mahdavi) and bean (Phaseoulus vulgaris cv. COS16) in sandy loam and clay loam soils under greenhouse conditions. Results showed that aeration porosity is the predominant factor controlling WU, WUE, Ky and shoot biomass (B...
متن کاملCO2 enrichment and soil nitrogen effects on wheat evapotranspiration and water use efficiency
Evapotranspiration (ET) and water use efficiency (WUE) were evaluated for two spring wheat crops, grown in a well-watered, subsurface drip-irrigated field under ambient (about 370 mmol mol−1 during daytime) and enriched (200 mmol mol−1 above ambient) CO2 concentrations during 1995–1996 and 1996–1997 in Free-Air CO2 Enrichment (FACE) experiments in central Arizona. The enriched (FACE) and ambien...
