Manures increase soil fertility by enriching the soil with organic matter and nutrients as it is prepared by the decomposition of animal excreta and plant wastes. On the other hand, fertilizers are mostly inorganic compounds whose excessive use is harmful to the symbiotic micro-organisms living in soil. Their excessive use also reduces soil fertility. Hence, fertilizers are considered good for only short term use.

i) Fertilizers are manufactured by chemicals such as nitro gen,phosphorus, potassium etc. ii) Water pollution take place by using these. iii) By excessive use of these soil fertility is not maintaining. |
Manures is prepared by the decomposition of animal and plant wastes.
i. Manure helps in enriching soil with nutrients and organic matter and increasing soil fertility.
ii. The bulk of organic matter in manure helps in improving the soil structure. This involves increasing the water holding capacity in sandy soil.
iii. Manures contain substances which act as stimulants for seed germination and plant growth.
On the other hand, fertilizers are mostly inorganic compounds prepared from various chemicals.
i. Their excessive use also reduces soil fertility. Continuous use of fertilizers in an area can destroy soil fertility as the organic matter in the soil is not replenished.
ii. It also affects various microorganisms present in the soil which are beneficial for maintaining soil quality. Disrupting the nature of soil will hamper in the production of crop. Hence, fertilizers are considered good for only short-term use.
Manure contains many organic substances of biological origin which can be easily degraded and absorbed by plants. It helps in recycling of biological waste. They increase the fertility of soil for long duration without causing any harm. The chemical fertilizers, on the other hand, improve soil fertility for short duration but cause environmental hazard. Continuous use of fertilizers in a particular area causes destruction of soil fertility.
