Question

What are manure and fortilizers​

Answer 1

Answer:

Manuring is the process of addition of natural or chemical sources of nutrients for the crop. Natural sources include dead wastes of plants, humans and animals, excreta and other wastes. These on decomposition give organic products called organic manure or simply manure.

Manure improves the water holding capacity, aeration, and texture of the soil. These lead to the development of a new method of farming called organic farming where only organic fertilisers, pesticides, etc. are used.

Fertilisers are chemical compounds which include salts or organic compounds like urea, ammonium sulfate, sodium nitrate etc. They are the sources of plant nutrients like potassium, nitrogen, and phosphorus. Fertilisers are commercial products mainly manufactured in factories. They have enhanced the yield spontaneously.

Chemical fertilisers should be used in optimum amount with great care. Their excess use may lead to soil infertility, water pollution, and even cause disease. Overall, it damages the crop. Hence it is advisable to use organic manure instead of chemical fertilisers.
