This statement contains some common misconceptions about the relationship between adding nitrogen and phosphorus chemicals to soil and their effects on the environment including the carbon levels.
The use of fertilizers containing nitrogen and phosphorous contribute to what is termed eutrophication, which is the increase of nitrogen and phosphorus in bodies of water like lakes and rivers because of water runoff from farms. Nitrogen can cause the death of fish and life in the body of water, what are...
