Natural Fertilizer in Agriculture

Posted on

Natural nutrient source can be found in animal waste, plants, husks, and other agro-industry waste. Soil with rich natural ingredients can bond with water better than usual. Natural fertilizer is a good repairer of soil structure. Natural fertilizer is low in N, P, and K, but rich in micronutrients. Natural fertilizer is good in preventing erosion, crusting and cracking. It’s also good in repairing internal drainage system.

Nitrogen and other nutrients are released from natural fertilizer slowly through mineralization process. This ensures continuous and long term fertile soil. The application of natural fertilizer is more or less the same as chemical fertilizer.

General characteristics that natural fertilizer has are as follows:

  • Low nutrient level: Generally, nutrient level in natural fertilizer is quite low. It varies from one ingredient to another but still generally low.
  • Slow nutrient supply: Nutrients in natural fertilizer needs microbe activities in soil to work thus supplying nutrients from natural fertilizer is not fast and plentiful enough for your crops.

Roughly, the benefit of using natural fertilizer is in how it reacts with soil’s physical characteristics. From the surface value, you can see that the soil will turn colors from bright to dark. Natural fertilizer causes soil to be loose and fertile and most suitable for plant roots to grow. Natural fertilizer also helps sandy soil to bond within particles and with water more easily.

Ideally, natural fertilizer is mixed with chemical fertilizer for maximum benefit. This fertilizer mixture affects soil’s chemical characteristics, elevating cation exchange capacity and nutrient level.
