Farming practice threat

In last few decades with the advancement in agricultural farming practices such as use of fertilizers, pesticides, herbicides, animal manure and other agro-chemicals we are able to achieve higher agricultural production but currently also facing a big problem of agricultural land and water contamination. Also excessive use of chemicals resulted in desertification, seepage and loss of fertile layer.

Nowadays, agricultural land and water contamination not only limiting agricultural production but residues of variety of pesticides and chemicals left has also threaten public health as well.

Agricultural water contamination

Agricultural runoff is water sent from farm fields due to irrigation and rain containing fertilizers, pesticides, animal waste, or soil particles, which can enter and contaminate sources of drinking water, local streams, lakes, ground water and rivers.

We have to ultimately use such polluted water for current and future agricultural needs leading to adverse effects on plants and human health.

In addition to this agricultural runoff can also trigger harmful algae blooms in coastal waters.

Polluted water in the field washes the essential nutrients for plant growth from the soil.

Water pollution also makes the soil acidic and have adverse effects on solubility of nutrient ions like iron, magnesium, potassium and calcium ions. As a result, plants become more susceptible to drought, fungal infections and insects. • Water pollution also leaves large amounts of aluminium in the soil and increases toxicity of soil, which can be harmful to plants.

Heavy metals contamination shows reduction in growth, performance and yield.
