Question

Quizplus · Accepted Answer

Organic fertilizers such as compost, manure, and plant debris are rich sources of organic matter, which decompose and contribute to the humus content of the soil. Nitrogen, phosphorus, and potassium fertilizers are inorganic and do not significantly increase the humus content. Inorganic fertilizers only provide specific nutrients to plants, which may improve growth and yields in the short term, but do not improve soil structure and health in the long term.
