Optimizing Soil Moisture Uniformity and Irrigation Management
This research is a study on the relationship of irrigation water treatments and soil moisture distribution uniformity (DU). Soil moisture distribution was based on long-term data sets that were collected during wet and dry soil conditions (from permanent wilting point to field capacity) using a novel electromagnetic sensor-based platform moving inside subsurface horizontal access-tubes. The irr...
متن کاملEffects of salinity and irrigation water management on soil and tomato in drip irrigation
In this research, the effects of irrigation with saline and fresh water through drip irrigation method and using two irrigation management strategies: M1, M2 (M1 is irrigation with fresh water in alternative with saline water, M2 is saline water in first half time of each irrigation event and fresh water in the second half), on the yield, water productivity (WP), soil salinity, plant height...
متن کاملEffects of Irrigation and Nitrogen Fertilizer Input Levels on Soil NO3−-N Content and Vertical Distribution in Greenhouse Tomato (Lycopersicum esculentum Mill.)
The purpose of this study is to investigate the interactions between irrigation and fertilizer treatments on soil NO3 (-)-N content and vertical distribution under drip fertigation in greenhouse tomatoes. Randomized block design with three replications and the treatments consisting of three levels of irrigation and three levels of N fertilizer were used. Three irrigation levels were W1 (100% E...
متن کاملSoil nitrate testing supports nitrogen management in irrigated annual crops
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 ...

it more susceptible to leaching (Albus and Knighton, 1998). Higher moisture contents will also raise microbial Groundwater and surface water are significant resources for rural activity including mineralization (Skopp et al., 1990). water supplies, and certain agricultural practices may have substantial effects on these resources. An 11-yr study was started in 1989 near The increase in minerali...
