Difference between Organic and Inorganic Fertilizers:
Organic Fertilizers:
1. Improves the Soil Structure
2. Improved Water Holding Capacity
3. Soil becomes more permeable
4. Slow release of Nutrients
5. Decreases leaching of nutrients from soil
6. Doesn’t produce acidity or alkalinity in the soil
7. Upon Decomposition produces organic acids while helps to dissolve minerals
8. Increases the growth of microorganisms like earthworms
9. Usually applied 15-20 days before the crop is sown
10. Not used in liquid form
11. Used in huge quantity
12. Organic manures are incorporated in soil
Example of Organic Fertilizers
Organic fertilizers are fertilizers derived from animal matter, animal excreta (manure), human excreta, and vegetable matter (e.g. compost and crop residues). Naturally occurring organic fertilizers include animal wastes from meat processing, peat, manure, slurry, and guano.
Inorganic Fertilizers
1. No effect on soil structure
2. No water holding capacity
3. No effect of fertilizer on Permeability
4. Fast release of nutrients
5. No such effects
6. Fertilizers like sodium products produce acidity and alkalinity in the soil
7. No such effects
8. Slightly helps in the growth of microorganisms
9. Nitrogen fertilizer is applied immediately before sowing.
10. Used as foliar spray
11. Used in Small Quantity
12. It is also incorporated in soil but may be used as top dressing
Example of Inorganic Fertilizers:
Inorganic nitrogen fertilizers come in many different forms, such as ammonium nitrate, potassium nitrate, calcium nitrate and urea. These fertilizers contain high levels of nitrogen, one of the most vital nutrients for plant growth.
