What are the common mistakes in fertilizing methods in daily practice? What are the reasons? Experienced netizens are also asked to help explainIn the process of agricultural planting, fertilizing crops is the primary method to increase crop yield and income, but some wrong fertilizing methods can greatly reduce fertilizer efficiency, so Zhongdi Web has compiled some common wrong fertilizing methods, listed below for netizens' reference.
Mistake 1: Drying farmyard manure in the sun:
Common human feces and chicken manure have become the main base fertilizer for vegetable production in greenhouses, but vegetable growers often dry human feces and chicken manure in the field until they lose water and become dry for convenient application. This practice causes fly maggots to breed, nitrogen to volatilize, and the nitrogen nutrient of the fertilizer to be lost.
Mistake 2: Using calcium magnesium phosphate as base fertilizer on alkaline soil:
Calcium magnesium phosphate is a weakly acidic fertilizer, insoluble in water, and only under weakly acidic conditions can it gradually convert into water-soluble phosphate to be absorbed by crop roots. When applied on alkaline soil, it cannot solve the urgent need of crop seedlings for phosphorus, causing physiological phosphorus deficiency.
Mistake 3: Applying superphosphate as topdressing on the soil surface:
Because phosphorus has low mobility in soil, with a movement range of 1-3 cm. Therefore, surface application is difficult to deliver to the crop rhizosphere, and thus cannot play the role of supplementing phosphorus in the crop.
Mistake 4: Watering immediately after applying urea:
Because urea is an amide nitrogen fertilizer, easily soluble in water, and after being applied to the soil it must undergo decomposition before it can be transformed into ammonium bicarbonate and absorbed and utilized by crops. If watered immediately after surface application, urea is easily lost with water, reducing fertilizer efficiency.
Mistake 5: Broadcasting ammonium bicarbonate with irrigation water:
This method often causes more fertilizer at the water inlet, uneven crop growth, and difficulty in management. In the afternoon, as the greenhouse temperature rises, ammonia gas escapes from the soil, scorching the lower leaves of crops and causing fertilizer damage.
