Using organic fertilizers has notable benefits, particularly in terms of improving soil structure and enhancing microbial activity. Organic fertilizers are derived from natural sources, such as compost, manure, or plant materials, and they are known to contribute to the long-term health of the soil.

When organic fertilizers are applied, they can improve soil structure by increasing the organic matter content. This improvement can lead to better aeration, enhanced water retention, and increased nutrient-holding capacity. Healthy soil structure allows for better root development and overall plant growth.

Additionally, organic fertilizers support a diverse population of microorganisms, which play crucial roles in nutrient cycling and soil health. These microbes help break down organic matter into forms that plants can readily absorb, promoting nutrient availability. The presence of beneficial microorganisms can also suppress soil-borne diseases and improve plant resilience.

In contrast, options that mention quick nutrient release, higher concentration of nutrients, and lack of odor during application focus on characteristics of synthetic fertilizers. Synthetic options typically provide immediate nutrient availability and can have a higher concentration of nutrients per unit, but they may not offer the long-term benefits associated with improved soil health that organic fertilizers provide.
