the use of large amount of herbicides pesticides and fertilizers by the farmer in their forms lead to the​

Answer 1

Many farmers choose to use chemicals to keep weeds and pests from destroying their crops and to add more nutrients to the soil. There are three different kinds of pesticides; herbicides, insecticides and fungicides. All three of these pesticides are used to kill different kinds of pests that can be found on a farm. Farmers that make the decision not to use any chemicals are called organic farmers.

Plants need nutrients in order to grow on a farm. Nutrients such as carbon, oxygen and hydrogen are always available to the plants. Unfortunately, nutrients that the plants also need such as nitrogen, phosphorus and potassium can run out. To put more of these nutrients back into the soil many farmers will add fertilizers. Replacing these nutrients back into the soil with fertilizers can help the growth of the plant, which then increases the crop yield on the farm.

Because insects make up 3/4 of all species on earth, they can be a big problem on a farm. Insects such as worms and beetles can infest a crop and destroy it. To keep this from happening many farmers will spray their crops with insecticides. Insectisides are strong chemicals that will kill the insects that will harm the crop without killing the actual crop.

One of the biggest concerns for farmers is weed control . When weeds grow in farmland they can damage the crops and decrease the crop yeild of the farm. To get rid of the weeds without killing the crop many farmers spray their fields with herbicides. Herbicides are also made up of strong chemicals.
