US: Succesful field trial with fertilizer based on organics recycled by supermarkets

California Safe Soil a privately held 100% sustainable and organic fertilizer manufacturer, and Diedrich Farms, a leading California tomato and vegetable farm system, announced that they have successfully completed a processing tomato field trial of Harvest-to-Harvest, the fertilizer and soil amendment produced using CSS’s breakthrough technology, using organics recycled by supermarkets.

Diedrich has been a market leader in applying tomato crop and soil technology. Their “Grower Standard” case in the Field Trial reached an extraordinary crop yield of 74.2 tons per acre. This compares with the California State average of 47 tons per acre. Diedrich agreed to reduce their use of conventional fertilizers, and apply Harvest-to-Harvest in the Field Trial with CSS, saving money in the process. This case yielded 83.4 tons per acre (a 12.4% increase over the Grower Standard), and also scored very well in color, brix and solids, three key value measures for tomato farmers.

Dan Morash, Founder of CSS, said, “Our goal has been to improve sustainability metrics, like increased organics recycling rates, improved food safety, reduced greenhouse gas emissions, increased soil organic matter content, and improved water utilization and quality. It’s important to show that good organics can increase crop yields for commercial farmers – a “win-win” for farmers and the environment.”

Todd Diedrich, Owner of Diedrich Farms, said, “We work hard to be good stewards of our land, to use sustainable growing practices for the long term. We’re committed to being a leader in applying science-based solutions to our farming challenges. We expect our collaboration with CSS to help us stay at the cutting edge of agricultural science, to produce market leading results for our own farm, and for the farms of others that we manage.”
