Through the use of biofertilizers, healthy plants can be grown, while enhancing the sustainability and the health of the soil. Biofertilizers can be expected to reduce the use of synthetic fertilizers and pesticides, but they are not yet able to replace their use. As of 2024, more than 340 biofertilizer products have been approved for ...
Diazotroph fertilizer is a kind of biofertilizer that can use nitrogen-fixing microorganisms to convert molecular nitrogen (N 2) into ammonia (which is the formation of nitrogen available for the crops to use). These nitrogen nutrients then can be used in the process of protein synthesis for the plants.
Nitrogen fertilizer being applied to growing corn in a contoured, no-tilled field in Iowa.. Nutrient management is the science and practice directed to link soil, crop, weather, and hydrologic factors with cultural, irrigation, and soil and water conservation practices to achieve optimal nutrient use efficiency, crop yields, crop quality, and economic returns, while reducing off-site transport ...
Converting sewage to fertilizer saves money on landfill costs and is a cheaper fertilizer for farmers. But it has potential health impacts. Some states have banned sewage-made fertilizers.
Agricultural use of inorganic fertilizers in 2021 was 195 million tonnes of nutrients, of which 56% was nitrogen. [20] Asia represented 53% of the world's total agricultural use of inorganic fertilizers in 2021, followed by the Americas (29%), Europe (12%), Africa (4%) and Oceania (2%). This ranking of the regions is the same for all nutrients.
Using an aquatic herbicide Wide field margins can reduce fertilizer and pesticide pollution in streams and rivers Fish and other aquatic biota may be harmed by pesticide-contaminated water. [ 90 ] Pesticide surface runoff into rivers and streams can be highly lethal to aquatic life , sometimes killing all the fish in a particular stream.
A variant in Indonesia combines rice, fish, ducks and water fern for a resilient and productive permaculture system; the ducks eat the weeds that would otherwise limit rice growth, reducing labour and herbicides; the water fern fixes nitrogen; and the duck manure and fish manure reduce the need for fertilizer.

It is an ancient technique with clear evidence of its use since at least 3000 B.C. [8] No-till farming is not equivalent to conservation tillage or strip tillage. Conservation tillage is a group of practices that reduce the amount of tillage needed. No-till and strip tillage are both forms of conservation tillage.
