• Agricultural Field Demonstrations: Remediating Low Soil Organic Matter with Compost in Pepper and Corn Production - Tuesday, August 8, 2017 at

  • Agromin, in partnership with SA Recycling and Circle Vision, have commissioned a six-month, 36-acre field demonstration in Coachella, California to assess the economic value of compost applied to carbon deficient soils.  

    The soil at the property contains less than one percent of organic matter on a dry weight basis. Pepper and corn crop yields at the Coachella property are low by California standards, producing 1,250 carbons of peppers versus an average of 1,800, with 430 boxes of sweet corn against a market average of 500.  

    Benefits of Organic Matter Between three and six percent organic matter levels in the soil is generally considered ideal and known to maximize yields while reducing water use and fertilizer leaching. Organic amendments improve water holding capacity and soil structure by reducing density and increasing porosity. This improved soil structure enables deep root growth, a reduction in surface water evaporation and wicking of salts and an enhancement of the environment for growth of beneficial microbes responsible for transporting nutrients into plants. Compost brings organic nitrogen, phosphorous and potassium to the soil so that the need for synthetic fertilizers is minimized. 

    Introducing Biochar to Meet Environmental Challenges One of the challenges with building up soil organic matter in a place like Coachella, where summer temperatures reach 120 degrees F, is premature compost degradation. Therefore, the trial has included an additional treatment combining compost with biochar, with the expectation that biochar will stabilize the compost. 

    Biochar is the black carbon residue produced from heating wood under an oxygen-deficient environment at high temperatures. Originally known as "Terra Preta" (black soil), biochar was created by indigenous people in the Brazilian Amazon over 2,000 years ago using cooking fires. Soil containing biochar have maintained exceptionally high levels of fertility and soil organic matter across the ages in environments that are otherwise devoid of rich plant growth. The world's most productive agricultural soils found in the U.S. Corn Belt, northeastern China and the Ukraine are rich in biochar created from naturally occurring vegetation fires. 

    Study Expectations With the introduction of compost and biochar into the soil, we expect to see yield improvements in excess of 20 percent and the naturally occurring compost nutrients eliminating the need for fertilizer. Overall, after factoring in the compost costs (purchase, transportation and application) we anticipate an overall profitability increase by well over $1,000 per acre.

  • Custom "Class A" Top Soil - Monday, August 7, 2017 at
  • Agromin has developed a custom top soil that meets "Class A" specifications by using a variety of amendments including compost and mining overs (discards).

    A key feature of its development was the creation of a linear program (multivariable computer program) that chooses materials based on their properties and price in a way that achieves Class A specification while minimizing costs.

    The conventional way to supply top soil is to dig it up from one location and apply it to another--a process that is clearly destructive and not sustainable. Additionally, it is unusual for natural top soil to achieve the Class A specification for import purposes.

  • Agromin Opens Recycling Facility in Oceanside - Monday, June 12, 2017 at

  • Agromin is now operating a 3-acre on-farm organics composting facility in Oceanside. Located on Nagata Brothers Farm, Agromin is composting about 100 tons of green waste daily collected from San Diego County cities.

    The collected material is turned into our OMRI Listed Compost 100 and ES2 products and delivered in bulk to the farm. Agromin's OMRI Listed Compost 100 can be used in certified organic farming, nurseries and gardens according to the USDA Program rule. ES2 mulch is ideal for cooling the root zone, saving water, controlling erosion and preventing weed growth. It is commonly used in orchard applications and in public works projects as it is Environmentally Safe (ES) and meets California Department of Transportation specifications.

    For more information or to arrange delivery, call 1-800-AGROMIN.

  • Agromin Joins San Diego County Farm Bureau - at

  • Agromin is a proud new member of the San Diego County Farm Bureau. The farm bureau is in the middle of a capital campaign to create a San Diego Ag Hub that will house bureau headquarters and become the central meeting place for the agricultural industry in the county. Agromin happily pledged $5,000 to help fund the project and plans to become an active member.
