Effect of nitrogen fertilizer on plants

2016-06-14
 Nitrogen fertilizer is mainly to promote the trees growth, increase chlorophyll and enhance vegetative growth. Too much nitrogen fertilizer will cause result as below: soft crop tissue, longer stems and leaves, too vulnerable to against pests, lower ability to against cold.


The lack of nitrogen fertilizer will lead to plant become thin, leaf yellow green, grow slowly and do not bloom.



Nitrogen fertilizer can be dived in two kinds: plant nitrogen fertilizer and animal nitrogen fertilizer. Human waste, horse dung, cattle dung, sheep manure, pigs and fish manure all belong to animal nitrogen fertilizer. Sesame dregs, soybean and rapeseed, cottonseed and other nitrogenous fertilizer all belong to plant nitrogen fertilizer. These two kinds are called organic fertilizer. Mineral fertilizer also named inorganic fertilizer or chemical fertilizer. Ammonium sulfate, ammonium nitrate, urea, ammonia, etc., are available nitrogen. They are often used as foliar application, frequently used as the root fertilizing will cause soil compaction.
