Answer:

Ans 1- when we use the chemical fertilizer which are made up of chemical compounds such as phosphorous , sulphate , zinc , potash other non metals then then can reduce or decrease the soil fertility because they are harmful for soil and also for animals that are part of our environment . Chemical fertilisers are very rich in plant nutrition but they are not able to add any type of humus like earthworms into the soil . Point is that the humus fixes nitrogen and increase the soil fertility as the organic manure are able to add humus into the soil , that's why they are useful for enviornment and they are also not harmful for anything because they are made up of cattle dung, vegetable peels and other organic materials which are environmental. Thus to use the organic manure we can protect the enviornment
