uk- An ideal source of nitrogen and phosphorus for plants – nutrients from fertilizer quickly enter the soil solution and become available to plants.
- Fertilizer has a special property that is to alkalinize the environment around the granules.
- Due to the ammonium form of nitrogen, the nitrification process involves the gradual release of nitrates, which are quickly absorbed by the roots. This temporary process is accompanied by a noticeable decrease in the pH of the environment.
- Fertilizer is recommended to be applied to all crops, both for the main and seedbed applications.
