Organic fertilizers are naturally slow-releasing and
provide nutrients to plants where they need it.
As long as humans cultivate the earth, they have been practicing organic cultivation techniques. Since the Second World War, agriculture has relied on chemically synthesized fertilizers and pesticides. These artificial chemicals temporarily increased the output of many crops, but also increased long-term production costs, caused air and water pollution, changed the soil structure, and destroyed the entire ecosystem.
Organic fertilizers, whether they are meals, fertilizers or compost plants, contain N-P-K (nitrogen-phosphorus-potassium), trace minerals, enzymes, vitamins and many organic matter. Among these ingredients, 100% is useful for soil and plants. In contrast, synthetic fertilizers do not contain organic matter. Soil microorganisms must have a carbon source. If no carbon source is provided, the microorganism will absorb the carbon source from the soil. Each application of fertilizer will consume soil health.
Unlike synthetic fertilizers, organic fertilizers do not produce large amounts of salt, such as nitrate, which can interfere with or even kill beneficial soil organisms. Organic fertilizers release nutrients slowly and naturally. All ingredients can be used by plants, because organic fertilizers do not contain useless fillers like synthetic fertilizers.
Apart from N-P-K, there is nothing else to feed soil and plants, just like feeding children with soda. Soil and people need nutritional balance. For some unknown reasons, fertilizers recommend continuing to emphasize these three nutrients, with a special emphasis on high nitrogen content. Studies have shown that 80% or more of all synthetic nitrogen applied to the soil will volatilize or leach, and reaching 10% to 20% of plants is harmful. Other studies have shown that excessive fertilizer can slow down or even stop the activities of microbial communities and micro-animals, such as beneficial bacteria, algae, fungi and other microorganisms. Harsh fertilizers also destroy large organisms such as macros, millipedes, and cent, which is extremely important for natural processes in the soil.
The most important substances in plants and crops are organic substances that become humus during decomposition. Humus becomes humic acid, other beneficial acids and mineral nutrients. Organic fertilizers are better than man-made products because they are derivatives of plants and animals and therefore contain most or all trace elements present in growing plants and animals. In addition, organic fertilizers are naturally released slowly and provide nutrients to plants when needed.
