In response to Napa Sanitation District's interest in expanding its delivery of recycled water to vineyards for irrigation, we conducted a feasibility study to assess the suitability of the water for this use. We adopted two approaches: comparing t

Water management practices in California rice production can affect salinity in the field. This is particularly important because rice is one of the most sensitive crops to salinity. We extensively monitored salinity patterns in dozens of rice fiel

Field studies conducted by UC and under controlled greenhouse conditions by the U.S. Department of Agriculture's Agricultural Research Service indicate that rice is more sensitive to salinity than current guidelines suggest. This information is par

To estimate the water use of vegetable and row crops, crop coefficients were developed using portable Bowen ratio instruments that were constructed and tested against lysimeters. These instruments measured evapotranspiration (ET) in fields of veget

Three devices that physically treat irrigation water were tested in the laboratory and the field. Results of these experiments indicate these water conditioners were ineffective in increasing the infiltration rate of water into the soil or in preve

Subsurface drip irrigation has a number of potential advantages over conventional surface irrigation; it curtails weed growth and reduces water loss due to high irrigation uniformity. Depending on a system's design and management, however, it may n

Poor soil-water infiltration in the eastside of the San Joaquin Valley is frequently attributed to low-salinity irrigation water. This report assesses the feasibility of improving infiltration rates by blending the more saline westside drainwater w
