Apply phosphate fertilizer this way, and crops will resist drought and increase income
Crops absorb phosphorus fastest during the seedling stage, and the seedling stage is also the critical period for phosphorus nutrition. If phosphorus is deficient during the seedling stage, it will affect the later growth of the crop. In our province, spring temperatures are low, soil microbial activity is weak, and the release of soil available phosphorus is low. In addition, low soil temperature weakens the root system's ability to absorb nutrients, making it difficult to meet the crop's needs during the critical period of phosphorus nutrition. ...
