Nitrogen fertilizer Organic compounds and soil minerals form a natural supply of nitrogen to plants. However, this is usually not sufficient to meet the crops' need. When there is an insufficient amount of nitrogen available in the soil, this is the limiting factor to optimal plant growth. This can be supplemented with mineral fertilizers during the growth periods.we offers a broad range of nitrogen fertilizers. Urea, Calcium ammonium nitrate (CAN) and magnesium ammonium nitrate are well-known examples.
