Organic farmers do not use synthetic pesticides and fertilizers, one of the primary contributors of greenhouse gases. Healthy soils help crops obtain nitrogen, phosphorus, and other nutrients from organic soil organic matter.

What kind of fertilizer do organic farmers use?

Compost, cover crops, plant by-products, animal manure, and other biological materials form the bulk of what is applied to organic fields for fertility. Organic farmers are also permitted to supplement the addition of organic matter with the use of other natural products, such as mined minerals.

What are the disadvantages of synthetic fertilizer?

Synthetic Fertilizer Disadvantages Synthetic fertilizers kill beneficial microorganisms in the soil that convert dead human and plant remains into nutrient-rich organic matter.

What two methods do organic farmers use to enhance nitrogen on their farms?

The other method of enhancing sufficient nitrogen supply in organic farming is the use of cover crops.
