- ... Leaching is an important aspect of irrigation water management, as it must be minimal to save available irrigation water resources, prevent shallow groundwater tables, and reduce nutrient loadings to the groundwater. However, at the same time, leaching should be sufficient to maintain root zone salinity levels below the threshold to prevent yield reduction. Therefore, monitoring leaching is the ke ...

- ... Alfalfa is one of the most cultivated crops in the US, and is being used as livestock feed for the dairy, beef, and horse industries. About nine percent of that is grown in California, yet there is an increasing concern about the large amounts of irrigation water required to attain maximum yield. We introduce a conceptual framework to assist in the design and management of subsurface drip irrigati ...
