Study Notes

Types of Fertilizers

Multiple-nutrient granules in compound fertilizers promote uniform distribution of micronutrients in the root zone.
Compound fertilizers are typically more expensive than other fertilizers.
Liquid and powder fertilizers can be applied in different ways, including broadcasting, top dressing, and placement.

Application of Solid Fertilizer

Broadcasting: Spreading fertilizer evenly across the soil area before or during crop growth; includes top dressing and basal application.
- Top Dressing: Fertilizer is spread over standing crops; must avoid plant contact to prevent damage.
- Basal Application: Fertilizer is mixed into the soil at sowing time.
Placement: Fertilizer is positioned in the soil without regard to seed or plant location; suited for small quantities and poorly developed root systems.
- Plough Sole Placement: Fertilizer is placed at the bottom of plough furrows, recommended in dry soils.
- Deep Placement: Involves placing fertilizer briquettes 7-10 cm deep near plant roots, promotes gradual nitrogen release.

Application of Liquid Fertilizers

Foliar Application: Direct spraying onto leaves using a small amount of fertilizer.
Injection into Soil: Liquid or gaseous fertilizers are placed below the soil near roots.
Fertigation: Mixing water-soluble fertilizers with irrigation systems.
Aerial Application: Spraying crops from an agricultural aircraft.

Nutrient Deficiency in Plants

Nutrient deficiency occurs when plants lack essential nutrients necessary for growth.
Growing mediums in native nurseries often include artificial soils made of peat moss or compost.

Types of Growing Media

Coco Peat: Derived from coconut husks; enhances soil drainage.
Perlite: Expanded volcanic glass; very porous and water-absorbent.
Peat Moss: Partially decomposed plant layers; forms slowly in bogs.
Sand: Naturally occurring; promotes proper airflow in soil.

Definition of Fertilizers

Fertilizers are organic or inorganic materials that supply essential nutrients to promote plant growth.
Types of fertilizers include organic and chemical, which can be in granular, powder, or liquid form.

Granular Fertilizers

Straight Fertilizers: Supply a single nutrient; examples include urea, rock phosphate, and muriate of potash.
Mixed Fertilizers: Combine multiple straight fertilizers to provide various nutrients.
Compound Fertilizers: Contain multiple nutrients in each granule, facilitating comprehensive nutrient supply.
