role of fertilizers
it provides plant nutrients.
fertilizers are produced in factories
fertilizers can be easily stored and transported
irrigation provide moisture for germination of sseds
it enhance soil erosion
Hope this helps you!!
Role of fertilizers in improving crop yield is as follows:
•There are certain nutrients required by plants in certain fixed amounts. Fertilizers play important role in the improvement of crop production by providing these nutrients to the crops. They supply nitrogen, potassium, and phosphorus to the plants.

When excess fertilizers are supplied to the soils and they are not absorbed by the plants and when irrigation is performed, the fertilizers get washed away and get accumulated in different water sources. By affecting the natural properties of water, fertilizers cause water pollution.
Role of irrigation in improving crop yield is as follows:
Irrigation provides water, necessary for the growth of plants and hence increases the crop yield.
Irrigation provides water, necessary for the growth of plants and hence increases the crop yield.If excess of irrigation water is used, then evaporation will deposit excessive salt on the surface of soil and decrease crop yield.
