How do you cut your water use by a third, cut your nitrogen use in half, maintain your tomato yield and improve your fruit quality?

“With patience, perseverance and by treating your soil like a living ecosystem — which it is,” says Jesse Sanchez.

Sanchez should know. He and Alan Sano have been experimenting with soil enhancements for 15 years on Sano Farms in Firebaugh.  They believe they have hit upon a winning strategy — though their experiments continue.

Today, they grow 50-ton-per-acre tomatoes with half of the nitrogen (120 units) and a third less water than before. They also report fewer weeds and better tomato...

Overhead irrigation systems have revolutionized agriculture across the United States and in other parts of the world, using less water than furrow irrigation and requiring significantly less labor and maintenance than drip systems. But in California, the No. 1 agriculture state in the nation, it hasn't gotten off the ground.

That is beginning to change.

UC Cooperative Extension and Fresno State agricultural production scientists researched overhead irrigation at the UC West Side Research and Extension Center for five years, growing wheat, corn, cotton, tomato, onion and broccoli and comparing them with crops produced under furrow and drip irrigation. With all of them except tomato,...

Farmers who have managed their soil with cover crops and conservation tillage are in better shape to weather El Niño this winter than those who have used traditional soil management methods, says Jeffrey Mitchell of UC Agriculture and Natural Resources (UC ANR).

“The soil-water interaction under various soil management practices will be quite clear if we do get the increased rainfall this winter that has been forecast,” Mitchell said. “Soil high in organic matter and covered by plant residue will allow increased water infiltration and storage, less water runoff and, on a large scale, increased groundwater...

Long-term research by UC Agriculture and Natural Resources scientists has documented the capacity for farmland in the San Joaquin Valley managed with conservation practices to sequester carbon, results that could give farmers a seat at the carbon trading table. The study was published this month in the Agronomy Journal.

Published research results provide evidence that farmers will need to get credit for sequestering carbon if such an opportunity arises in the future. In addition, the conservation practices have been shown to offer other environmental benefits – such as reducing dust emissions...
