Updated Fertigation Book

In California agriculture, there has been a gradual shift from gravity-fed irrigation to pressurized systems including micro-irrigation. Micro-irrigation systems have been implemented in over 60% of irrigated acreage in California and support a more intensively managed production system. The use of pressurized irrigation systems has made significant advancements possible, including more precise delivery of chemicals and nutrients to crops. Chemigation …


Role of Mineralization in Farming

California growers have taken on an important role in their state’s broader efforts on climate change, including responding to regulatory requirements to improve their nitrogen (N) use efficiency and reduce their environmental impact. To meet these regulations, while maintaining crop yield and quality, growers must consider all potential N sources, including organic amendments and irrigation water. It is essential that …
