Why advocate doing organic manure? What are the advantages over fertilizer?

1. Excessive use of chemical fertilizer will destroy the structure of soil and cause immeasurable damage to soil. But organic fertilisers can reverse the damage, because they contain organic elements that rejuvenate the soil.

2. The improvement of soil and crops by organic fertilizers is a cyclic and gradual process, while the targeted utilization of nutrients requires a certain amount of time and process, and often requires a large amount. But chemical fertilizers can improve the growing needs of crops in a short time, but also tend to lose a lot of nutrients.

3. There is no shortage of probiotics in organic fertilizers. These microorganisms can play a biological role in the soil, constantly improving the land and making the barren soil more fertile, but chemical fertilizer has the opposite effect.
