LD 437/SP179, establishing the Maine Healthy Soils Program



This bill establishes the Maine Healthy Soils Program and the Maine Healthy Soil Fund within the Department of Agriculture, Conservation and Forestry (ACF) to promote and expand the use of healthy soils practices among farmers and farmland owners. It requires the ACF to consult with the Department of Environmental Protection and cooperate with the University of Maine, the University of Maine Cooperative Extension, state and soil conservation districts and the United States Department of Agriculture, Natural Resources Conservation Service in the development and administration of the program.

The legislation also instructs the Commissioner of Agriculture to conduct education and outreach regarding soil health and encourage farmer-to-farmer learning and networking. Included in the law is an equity clause, stating that program incentives must be equitably distributed to “beginning and socially 36 disadvantaged farmers and ranchers as defined by 7 United States Code, Section 37 2279(a)”.

Soil Health Definition: 

The bill does not directly define soil health but refers to “the continuing capacity of soils to function as a vital, living biological system, increase soil organic matter, improve soil structure, strengthen water holding and nutrient holding capacity, improve nutrient cycling and result in net long-term greenhouse gas emissions benefits;”

Stated Goals:

  • “Improve the health, yield and profitability” of the state’s soil; 
  • Protect biodiversity;
  • Provide greenhouse gas emissions benefits;
  • “Promote healthy soils agricultural practices based on indigenous knowledge, current understanding and emerging soil science”;
  • Expand application of these practices among Maine farmers and landowners.

Program Required Measurements:

The legislation does not list required measurements, but mentions “depth of topsoil horizons, water infiltration rate, water holding capacity, organic carbon content, biologically accessible nutrient content, bulk density, biological activity and biological and microbiological diversity”.


None specified.

Funding Source:

The ACF will use existing budget funds to establish the program. The Maine Healthy Soils Fund will be able to accept public or private contributions to the program.

Funding Type:

The Maine Healthy Soil Program is based on voluntary incentives, providing financial and technical assistance to producers, and can be used to fund research.

Practices eligible for funding: 

The program aims to advance “healthy soils best practices” as determined by parameters such as increased biodiversity, enhanced resilience to weather extremes, better nutrient detention and improved carbon sequestration. It also refers to the 5 principles of soil health: “minimizing soil disturbance and external inputs: keeping soil covered, maximizing biodiversity, maximizing the presence of living roots and integrating animals into land management, including grazing animals, birds, beneficial insects and keystone species, such as earthworms.”

Agencies Involved:

Rulemaking process:

The Maine Healthy Soil Program will be developed by the ACF in consultation with the Department of Environmental Protection, University of Maine, Cooperative Extension, state and soil conservation districts and USDA/NRCS.
