The composition is different: phosphate fertilizer mainly contains phosphorus, and nitrogen fertilizer mainly contains nitrogen.

Different functions: Phosphate fertilizer can improve the stress resistance of plants, make plants grow more new roots, and promote the formation of flower buds and early maturity of fruits. Nitrogen fertilizer can strengthen vegetative growth and make plants grow more vigorously.

Different production methods: phosphate fertilizer is generally obtained from phosphate rock, and nitrogen fertilizer is generally obtained by artificial synthesis.

First, the composition is different.

1, phosphate fertilizer: the main component is phosphorus.

2. Nitrogen fertilizer: the main component is nitrogen.

Second, the role is different.

1. Phosphate fertilizer: Improve the cold resistance and drought resistance of plants, make plants grow more new roots, make stems and branches tougher, and promote flower bud formation and fruit early maturity.

2. Nitrogen fertilizer: increase chlorophyll content, strengthen vegetative growth, and make plants grow more vigorously.

Third, the mode of production is different.

1, phosphate fertilizer: decompose phosphate rock with nitric acid, phosphoric acid and sulfuric acid, and then separate the calcium in phosphate rock in the form of calcium salt.

2. Nitrogen fertilizer: The raw materials are liquid ammonia and carbon dioxide, which are synthesized under high temperature and high pressure.

Fourth, the types of tolerance are different.

1. Phosphate fertilizer: mainly includes ordinary superphosphate, superphosphate, calcium magnesium phosphate, bone meal, phosphate rock powder and other fertilizers.

2. Nitrogen fertilizer: mainly including urea, ammonium sulfate, calcium nitrate, ammonium bicarbonate and other fertilizers.
