Doc goes over the concept of organic fertilizers and when we use them vs. synthetic fertilizers. The first rule is temperature. Organic fertilizers only perform well once temps are above 75 degrees. Also he discusses the LONG TERM benefits of soil health.
Nutrient release: Organic fertilizers release nutrients slowly over time as they decompose or break down naturally. This slow-release nature ensures a steady supply of nutrients to plants and helps improve soil structure and microbial activity. Synthetic fertilizers, on the other hand, provide an immediate supply of nutrients to plants since they are readily soluble in water. However, they can also leach quickly through the soil, leading to nutrient runoff and potential environmental pollution.

Soil fertility: Organic fertilizers contribute to the long-term improvement of soil fertility by increasing organic matter content, improving soil structure, and enhancing beneficial microbial activity. They promote the development of healthy soil ecosystems. Synthetic fertilizers, while providing quick nutrients to plants, do not have the same long-term benefits for soil health and may even have negative impacts on soil quality if used excessively or improperly.

Environmental impact: Organic fertilizers are generally considered more environmentally friendly compared to synthetic fertilizers. They are derived from renewable resources, reduce dependence on chemical inputs, and contribute to sustainable agricultural practices. Synthetic fertilizers, especially when overused or misapplied, can lead to nutrient pollution in water bodies, soil degradation, and the emission of greenhouse gases during their production.

Nutritional quality: Organic fertilizers indirectly contribute to the nutritional quality of crops by enhancing soil health, which can lead to improved nutrient uptake by plants. However, the nutrient content in organic fertilizers can vary and may not be as concentrated as in synthetic fertilizers. Synthetic fertilizers provide specific nutrient ratios that can be tailored to meet specific plant requirements, but they do not contribute to long-term soil health and overall nutritional quality to the same extent as organic fertilizers.

Regulatory considerations: The use of synthetic fertilizers is regulated in many countries to ensure proper handling, storage, and application to minimize environmental impacts. Organic fertilizers, particularly those used in certified organic farming, have specific guidelines and regulations regarding their production, content, and usage.
