Organic manures are sometimes placed on the surface of soil and incorporated into the soil with a plough or rototiller before planting. Fertilizer can also be applied in bands at the bottom of plough furrows or broadcast or spread on top of ploughed soil that is then worked into the soil with a harrow before planting.

Application of Fertilizers to the Soil
Fertilizers are essential for providing plants with the necessary nutrients for healthy growth. There are several methods for applying fertilizers to the soil, each with its advantages and disadvantages.

Broadcasting
- Broadcasting is a commonly used method where fertilizers are spread evenly over the entire field.
- It is a simple and cost-effective way to apply fertilizers, but it can lead to uneven distribution and nutrient wastage.

Band Placement
- In this method, fertilizers are placed in bands or rows close to the plant roots.
- Band placement ensures that the nutrients are concentrated around the roots, promoting better absorption and reducing wastage.

Foliar Feeding
- Foliar feeding involves spraying fertilizers directly onto the leaves of plants.
- This method is used for quick nutrient uptake and is especially useful for correcting nutrient deficiencies in plants.

Top Dressing
- Top dressing involves applying fertilizers on the soil surface around the base of plants.
- This method is suitable for crops that are already established and helps provide nutrients directly to the root zone.

Injection
- Injection involves injecting liquid fertilizers directly into the soil through drip irrigation or injection systems.
- This method ensures precise application of fertilizers and reduces nutrient loss through leaching.

Conclusion
Choosing the right method of fertilizer application depends on factors such as the type of crop, soil condition, and nutrient requirements. Proper application of fertilizers is crucial for maximizing crop yield and promoting healthy plant growth.
