Mar 16, 2022 · How farmers can improve soil health and feed the planet: an expert explains. Over half of agricultural land has poor soil health, leading to productivity losses of $400 billion per year and expected food-price increases of 30% by 2035. Soil health is declining at an alarming rate, leading to productivity losses and food-price rises.
Sep 10, 2024 · Sustainable farming practices aim to produce agricultural products at a low environmental cost, ensuring food availability for future generations. These approaches combine the production of agricultural crops and livestock for site-specific uses, with an emphasis on long-term objectives including satisfying the food supply worldwide, improving the environment, making the most efficient use of ...
- Higher Matter. Soils rich in organic matter hold more air and water and produce higher yields than soils low in organic matter. They also supply a steady release of nutrients to plants, inhibit erosion, and host a robust population of beneficial microorganisms.
- Holding Nitrogen. Like carbon dioxide, nitrous oxide is a potent greenhouse gas. Good news: Organic methods can lock up nitrogen and carbon. USDA researchers in Beltsville, Maryland, compared nitrous oxide emissions from a variety of management treatments in a well-drained sandy site being transitioned from conventional agriculture to organic vegetable production over a three-year period.
- Fixing Nitrogen. Nodules that form on the roots of legumes contain bacteria that extract nitrogen from the air and fix it in the soil, allowing the next crops planted in the rotation to absorb it as a nutrient.
- Microbe Management. A robust population of beneficial soil microorganisms improves nutrient and water availability and helps suppress disease-causing pathogens.

Oct 15, 2023 · Organic farming practices help prevent erosion by keeping the soil covered and anchored. This protects topsoil, which is crucial for supporting plant growth and maintaining soil fertility. 4. Increased Biodiversity. Organic farms tend to support higher levels of biodiversity compared to conventional farms.
Dec 1, 2023 · Organic farming is beneficial for the environment, but conventional farming is responsible for global warming. So there is an argument that if organic farming helps to improve the quality of products, is environmentally friendly, and prevents all types of disease risk, it can counterbalance some reduction in crop yield.

How can sustainable agriculture improve soil health?
Organic farming was shown to improve soil physical and chemical properties such as soil organic matter content [26,39,57], aggregate stability , higher polysaccharide content and thicker top soil . These properties likely support better water infiltration and storage and thus might be advantageous considering the climate changed induced rainfall variability.
