What are Agrochemicals?

Agrochemicals, also known as agricultural chemicals, encompass a range of substances including fertilizers, pesticides, and insecticides. These are commonly used in agriculture to enhance plant growth and protect crops from pests.

While these chemicals were initially introduced to boost crop yield, their excessive application has led to serious environmental concerns. Agrochemicals can leach into the surrounding soil and water, entering the food chain and resulting in bioaccumulation.

Overuse of agrochemicals leaves behind significant amounts of residues, which can disrupt the nutrient balance and lower the quality of agricultural products. For instance, consuming food tainted with pesticide residues can potentially heighten the risk of asthma .

Impact on Soil

• May eliminate beneficial soil bacteria and other organisms
• Can escalate nitrate levels in the soil
• Potential to alter soil pH levels
• Can stimulate unnatural plant growth
• Can have residual effects on the soil
• Can bioaccumulate and enter the food chain

Impact on Water

• Can contaminate water making it unsafe for consumption
• Can promote algal blooms in larger water bodies, leading to fish deaths
• Can contribute to eutrophication
• Can cause water pollution
• Can change the chemical composition of water

Impact on Air

• Pesticide particles can mix with air, changing its composition
• Wind can carry polluted air over large distances, spreading its harmful effects
• Can increase the risk of respiratory diseases
