write two differences between manures and fertilisers
Answers
Answer:
Whether it is a small scale or large scale farming, the ultimate goal is to achieve economically feasible profits/yield. This requires good crop production and management practices like preparation of land, seed selection, usage of fertilisers, etc.
Usage of fertilisers is one of the processes adopted by farmers to increase the yield. However, their overuse can lead to a loss of capital in addition to crop loss. Most farmers are not aware of the effect of fertilisers, especially in developing countries.
Soil is the primary resource of nutrients like minerals for the crop. However, some types of soil are not rich in minerals or are infertile. Even repeated farming can result in loss of fertility of the soil. In such cases, the soil is to be replenished with nutrients from the external source.

Answer:
Though manure and fertilisers add to the fertility of the soil, they are different from each other. Manures are obtained from natural sources, whereas fertilisers are synthetically manufactured in the factories. Manures are eco-friendly, whereas fertilisers harm the useful microbes present in the soil and also decrease the soil fertility if used for a longer time.
