IRRIGATION Motor pumps are used for irrigating fields in modern farming.

INSECTICIDE Insecticide spraying machine

HARVESTING MACHINES Threshing machine

Disadvantages of modern farming Quality of the seed decreases due to the use of hybrid varieties. Growing same type of crops in the same field makes the soil poor in mineral contents. Causes air pollution due to spraying of insecticides. Food crops sprayed with insecticides cause threat to human life causing diseases.
