Study Notes
Collection of Organic and Inorganic Fertilizers
-
Compost Manure: Organic matter obtained from decomposed materials, critical for organic farming.
- Requires wet organic matter (green waste) to be heaped for weeks/months.
- Enhanced by aeration, shredding plant matter, and microbial action (worms and fungi).
- Benefits include nutrient release, soil conditioning, and natural pest control.
- Applications in erosion control, land reclamation, and horticulture.
-
Goat Manure: Odorless and easier to handle, it contains 22 lbs of nitrogen per ton.
- Acts as a soil conditioner, enhancing soil texture and nutrient availability.
- Improves water efficiency and oxygen levels in soil for plant roots.
- Promotes healthier plant growth and higher crop yields.
-
Green Manure: Crops specifically planted to enrich soil fertility.
- Can be planted post-harvest in fall or during crop rotation.
- Acts as a cover crop, preventing topsoil erosion.
- Includes legumes (e.g., alfalfa, clover) which fix atmospheric nitrogen, and non-legumes (e.g., ryegrass, buckwheat).
-
Cow Dung Manure: Originates from animal waste; provides nutrients upon decomposition.
- Improves crop productivity and soil physical properties.
- Less concentrated nutrients result in longer residual effects compared to chemical fertilizers.
- Categorized into bulky and concentrated organic manures.
-
Poultry Manure: Commonly used as fertilizer, it has high fertilizing value but lower concentration than chemical options.
- Best utilized near farms to minimize nitrogen loss during transport.
- Groundnut cake serves as both livestock feed and manure.
-
Neem Cake: By-product from neem oil extraction, rich in essential nutrients (NPK).
- Protects plants against nematodes and promotes soil fertility.
- Beneficial for crops such as paddy, cotton, and sugarcane.
- Enhances organic matter in soil, improving texture and aeration.
-
Cotton Cake: Dried cottonseed meal utilized as an organic fertilizer.
- Improves soil texture, moisture retention, and nutrient delivery.
- Suitable for various plants, including flowers and vegetables.
-
Nitrogen Fertilizers: Key types include ammonia, ammonium nitrate, and urea.
- Urea contains 46% nitrogen and presents advantages in handling and stability.
- Nitrogen is essential for plant growth, often injected directly into soil.
-
Single Super Phosphate (SSP): Contains 16% water-soluble phosphate, essential for pre-land preparation.
- Considered a standard fertilizer for comparison against others.
- Three grades available based on phosphate content: single, dicalcium, and triple superphosphate.
-
Murate of Potash: Potassium-rich fertilizer enhancing crop quality.
- Improves water retention and disease resistance in crops.
- Major consumers include China, USA, Brazil, and India; Brazil heavily relies on imports.
- Soluble in water, making it effective even in rainy conditions, suitable for a variety of crops including fruits and grains.
