Soil Health

Soil health refers to the soil's ability to function as a vital, living ecosystem that supports plants, animals, and humans. It emphasizes that soil is not just an inert medium but a dynamic, biological system. Agricultural management practices significantly impact soil health, with certain practices, like repeated tillage or excessive synthetic fertilizer application, potentially degrading the soil's functionality over time.

However, practices can be adopted to improve soil health. These are generally categorized into five core principles:

Keep the soil covered: This involves maintaining a protective layer on the soil surface, often through cover crops or crop residues, to prevent erosion, regulate soil temperature, and retain moisture.

Minimize soil disturbance: Reducing tillage and other physical disturbances helps preserve soil structure, protect beneficial soil organisms, and maintain organic matter.

Increase crop diversity: Rotating different crops and integrating various plant species can improve nutrient cycling, break pest and disease cycles, and enhance the soil microbiome.

Keep living roots in the soil: Maintaining continuous living roots in the soil, through practices like cover cropping or perennial systems, provides a constant food source for soil microbes and improves soil structure.

Integrate livestock: Thoughtfully managed grazing or the integration of livestock into cropping systems can enhance nutrient cycling, build soil organic matter, and improve overall soil fertility.
