What are the positive effects of fertilizers and pesticides and affect of modern agriculture fertilizer and pesticides on environment?
Fertilizers boost crop yields, but their excessive usage has hardened the soil, reduced fertility, strengthened insecticides, polluted air and water, and emitted greenhouse gases, creating health and environmental risks. Fertilizers make plants more resistant to pests. As a result, they are using fewer insecticides and herbicides, which results in healthier crops. Hence, fewer illnesses are present; giving the crops an aesthetic value.Pesticides can contaminate soil, water, turf, and other vegetation. In addition to killing insects or weeds, pesticides can be toxic to a host of other organisms including birds, fish, beneficial insects, and non-target plants. Fertilizers and pesticides help farmers grow more food on less land by protecting crops from pests, diseases and weeds as well as raising productivity per hectare. Excess use of fertilizers causes environmental pollution as their residual and unused amounts will become pollutants for air, water, and soil. It also initiates the process of eutrophication in the water bodies, decreasing the soil quality by killing the soil microflora, etc. Chemical fertiliser overuse can contribute to soil acidification and soil crust, thereby reducing the content of organic matter, humus content, beneficial species, stunting plant growth, altering the pH of the soil, growing pests, and even leading to the release of greenhouse gases. Uses of pesticides have proved to be advantageous: greater food output, increased earnings for farmers, and disease prevention. Despite the fact that pests devour or injure a substantial percentage of agricultural crops, it is likely that they would consume a higher percentage if pesticides were not used.

Fertilizers provide crops with nutrients like potassium, phosphorus, and nitrogen, which allow crops to grow bigger, faster, and to produce more food. Nitrogen in particular is an essential nutrient for the growth of every organism on Earth. Nitrogen is all around us and makes up about 78% of the air you breathe. Pesticides can contaminate soil, water, turf, and other vegetation. In addition to killing insects or weeds, pesticides can be toxic to a host of other organisms including birds, fish, beneficial insects, and non-target plants. Fertilizers boost crop yields, but their excessive usage has hardened the soil, reduced fertility, strengthened insecticides, polluted air and water, and emitted greenhouse gases, creating health and environmental risks. Both, fertilizers and pesticides have a strong bonding with each other. They stimulate crop's growth with greater yield, help in irrigation, crop protection, control pests, kill weeds, prevent diseases, and protect food and much more. By providing nutrients like nitrogen, fertilizers help plants thrive despite the threat of weeds and disease. Organic fertilizers, like manure, improve the fertility of soil by feeding microorganisms in the soil, reducing erosion and keeping soil well hydrated.
