What are agrochemicals?
Agrochemicals are chemicals used in agriculture to enhance plant and crop growth and safety. Agrochemicals were developed to help farmers protect their crops from pests and increase crop yields.
This article examines the effects of Agrochemicals in detail, including effects on crops, effects on water, and effects on soils.
Effects of Agrochemicals on Crops
• Agrochemicals are chemicals used in agriculture to enhance plant and crop growth and safety.
• Agrochemicals were developed to help farmers protect their crops from pests and increase crop yields.
Effects of Agrochemicals on Soil
1. Some types of pesticides remain in the soil, which is not easy to decompose and affect the growth of the next crop;
2. Change soil acidity and alkalinity and reduce the content of available inorganic salts and organic matter in soil;
3. Kill the beneficial organisms in the soil, thereby reducing the soil quality;
4. Cause soil compaction and salinization.
Prevention:
1. When choosing pesticides, understand their biochemical properties, and try to avoid choosing pesticides that are not easy to degrade in the soil (except for closed herbicides, soil fumigation pesticides, etc.);
2. If non-degradable pesticides have to be used, use acid-base modifiers (such as quicklime) after the effective period to neutralize and adjust soil acidity and alkalinity;
3. After using high-residue pesticides, apply farmyard manure and organic fertilizer to improve the soil, increase soil organic matter content, probiotics, and other the number of beneficial organisms in the soil.
Effects of Agrochemicals on Water
The pollution of pesticides to water bodies mainly comes from
(1) direct application of pesticides to water bodies;
(2) migration of pesticides applied on farmland to water bodies with rainwater or irrigation water;
(3) discharge of wastewater from pesticide production and processing enterprises;
(4) Residual pesticides in the atmosphere enter the water body with rainfall;
(5) During the use of pesticides, fog droplets or dust particles are moved by the wind and settle into the water body, as well as the cleaning of spraying tools and instruments.
