What is a critical factor affecting the effectiveness of fertilizers in soil?

The timing of fertilizer application is crucial for ensuring its effectiveness in soil. This is because the nutrient uptake by plants depends on several environmental and biological factors, including the growth stage of the plants and soil moisture levels. Applying fertilizer at the right time aligns nutrient availability with the periods when plants need them most, such as during active growth phases when they can readily absorb these nutrients.

For instance, if fertilizers are applied too early, nutrients can leach away before the plants have a chance to utilize them, particularly in areas with heavy rainfall or irrigation practices. Conversely, applying fertilizers too late may result in nutrients being available when plants are no longer actively growing, rendering the application ineffective. Thus, timing becomes a pivotal aspect of nutrient management to optimize plant health and crop yields.
