How is biogas humic acid phosphate fertilizer composted? Detailed method and steps
The uptake of phosphorus by rapeseed is greatest during the bolting and flowering stage, but as for the utilization of phosphorus and its yield-increasing effect, applying phosphorus at the seedling stage is best. Because phosphorus can be repeatedly utilized within the rapeseed plant, the earlier the absorption period, the greater the efficiency. Applying more phosphate fertilizer can promote an earlier growth period; generally, the seedling stage can be advanced by 2-4 days, the bolting and flowering stage by 2-6 days, and the maturity stage by 1-2...
