What are the benefits of manure to the environment?

When compared to more conventional fertilizer, manure properly applied to land has the potential to provide environmental benefits including: Increased soil carbon and reduced atmospheric carbon levels. Reduced soil erosion and runoff. Reduced nitrate leaching.

Can using fertilizers have harmful effects on the environment?

Some of the harm chemical fertilizers may cause include waterway pollution, chemical burn to crops, increased air pollution, acidification of the soil and mineral depletion of the soil. …
