Organic Almonds are Latest Test for New Fertilizer

California organic almonds have become the latest testing ground for a new organic fertilizer derived from organic food waste.

The fertilizer branded as Harvest to Harvest (H2H) by California Safe Soil (CSS) the company, which produces the product, will be used in a test plot at UC Davis where the effect will be compared with traditional chemical fertilizers.

Researchers from the school’s department of entomology and nematology, headed by Edwin Lewis, want to know if the H2H fertilizer improves the soil condition and aids plant growth. The products is already being tested on other California crops but the Spring planting of almond trees is the first long-term study.

A variety of almond trees were planted and will be observed for the next three years. The objective of the study is to see if the composted organic waste can increase the soil carbon content and the effect of the H2H on plant nutrition and growth.

A total of 258 almond trees were planted in the UC Davis test plot. There are currently about 13,000 acres of farmland using H2H. Crops include leafy greens, tomatoes, carrots, walnuts and almonds

The H2H liquid fertilizer was developed by CSS from organic material collected from supermarkets in the Sacramento area including Save Mart, Nuggets, Safeway and Whole Foods. According to the company the average grocery store throws away “over 500 pounds of food a day.” The company collects the unwanted organic waste and processes it in their facility near Sacramento. Currently the firm can process over 32,000 tons of waste a year.

Harvest to Harvest can be applied through traditional irrigation or sprinkler systems directly on to the soil and has been registered for organic use. According to the company the organic fertilizer is pathogen free and safe for all crops.

The new fertilizer has not been used on almonds supplied by American Export House but we look forward to seeing the test results when California organic almond growers can decide if the new fertilizer can be a solution to improved soil health and decreased food waste.

American Export House supplies organic and conventional almond varieties to customers throughout the United States. For more information contact AEH.
