What are organic fertilizers?

Organic fertilizers are natural substances derived from plant or animal matter that enrich soil fertility and support plant growth. This type of fertilizer enhances the soil's nutrient content through the breakdown of organic materials, such as compost, manure, or bone meal. These materials not only provide essential nutrients but also improve soil structure and promote beneficial microbial activity, which is vital for healthy plant development.

In contrast, the other options describe fertilizers that do not have the same benefits associated with organic fertilizers. Chemical fertilizers, for instance, are synthesized in laboratories and may enhance crop growth quickly but can lead to soil depletion over time and may harm beneficial soil organisms. Synthetic fertilizers boost productivity through concentrated nutrients but lack the holistic benefits provided by organic matter, such as improving soil health and reducing chemical runoff. Similarly, mineral-based fertilizers consist of inorganic materials and do not contain organic content, limiting their long-term benefits for soil health and sustainability.
