Question

Write two disadvantages of broadcasting method of fertilizer application.

Hint:

Tip: Use proper timing and splitting of fertilizer doses to reduce losses in broadcasting.

Answer 1

Broadcasting, a method of uniformly spreading fertilizers across the soil surface, presents significant drawbacks:
1. Inefficient Nutrient Utilization: Broadcast fertilizers are prone to losses via surface runoff, volatilization, or leaching.
This results in wasted resources, escalating cultivation costs without corresponding crop yield increases.
2. Inconsistent Nutrient Distribution: Broadcasting does not guarantee uniform nutrient delivery to the plant root zone.
Consequently, some plants may be over-fertilized while others receive inadequate amounts, leading to variable crop development.
Given these limitations, targeted application techniques such as banding or side-dressing are generally favored for improved effectiveness.
