Nitrate crops absorb the fastest, but the soil is not easy to preserve and easily lose with water, so topdressing is the best, but the base fertilizer is poor; urea is also easy to be lost, and it can only be absorbed by crops after being transformed into the soil. this process takes a long time when the soil temperature is low in spring, the effect is too slow, and it is not ideal to be used as base fertilizer. Only ammonium nitrogen is easy to be absorbed and preserved by soil, is not easy to be lost, and is not affected by low temperature, so it has the highest utilization rate and is the most ideal as base fertilizer. Therefore, ammonium nitrogen compound fertilizer is suitable to be used as base fertilizer. Click to get more compound fertilizer application techniques
