This document discusses agricultural pollution caused by chemical fertilizers and pesticides. It identifies the main causes of agricultural pollution as pesticides, fertilizers, contaminated water, soil erosion, livestock, and pests/weeds. It explains that fertilizers provide necessary nutrients to soil while pesticides are used to kill pests and weeds, but overuse can degrade soil quality. Specifically, inorganic fertilizers and pesticides can contaminate groundwater, reduce soil fertility over time, and damage habitats. The document provides examples of fertilizer types and outlines some methods for reducing pollution, such as nutrient management and cover crops.

6.  USED TO CORRECT SOIL DEFICIENCIES.
NECESSARY NUTRIENTS LIKE NITROGEN(N),
PHOSPHORUS(P), POTASSIUM(K), CALCIUM, MAGNESIUM
AND MANY MORE ARE OBTAINED FROM FERTILIZERS
Fertilizer (or fertiliser in
British English)
Pesticide
 To kill, destory pests and weeds.
 Decrease fertility of soil

7. TYPES OF FERTILIZERS
 Organic fertilizers-
• Obtained from naturally
occurring substances.
• Made from plant,
animal by products.
• Compost , manure,
marine byproducts.
 Inorganic fertilizers-
• Synthetically
manufactured.
• Like nitrogen fertilizers,
potassium fertilizers,
phosphorous fertilizers.
• Readily dissolved in
soil.

8. Advantages of Inorganic Fertilizers
and Pesticide
• Can make the desired ratio of nutrients
• easy to get
• lower cost
• Reduces soil life from 2 to 16 years.
• Reduces nitrogen fixation
• Destroys habitats, threatens species
• Contamination of ground water.

9. Disadvantages of Inorganic Fertilizers
• Accumulation of soil
acidity in soil which
increases aluminium
availability and hence
toxin.
• Fertilizer burn.
• Nitrogen fertilizer can be
converted by soil bacteria
to nitrogen oxide, a
greenhouse gas which
also causes acid rain.

12. Many ways to reduce pollution
• Nutrient management
• Cover crops
• Buffers
• Managing livestock waste
• Drainage water management
