What process is required before plants can utilize organic fertilizer?

Organic fertilizers need to undergo a process known as decomposition before plants can effectively utilize the nutrients they contain. When organic fertilizers, such as compost or manure, are added to the soil, microorganisms break down the organic matter into simpler compounds. This breakdown process converts complex organic materials into inorganic forms, making nutrients like nitrogen, phosphorus, and potassium accessible to plants.

Without this decomposition, the nutrients in organic fertilizers remain locked in their original complex forms and are not readily absorbed by plants. Therefore, decomposition is a crucial step in the application of organic fertilizers, allowing for optimal nutrient availability and enhancing soil health. The other processes mentioned, such as pesticide application, irrigation, or tillage, may play roles in overall agricultural practices but do not directly relate to the breakdown of organic materials for nutrient availability.
