How to Choose Red Fertilizer for Aged Greenhouses
Selecting bio-fertilizers Bio-fertilizers can release fixed nitrogen, phosphorus, and potassium from the soil and promote soil fertility. The use of biological fertilizers in older greenhouses is more effective. In order to ensure that vegetables absorb enough nutrients, it is recommended that vegetable growers use bio-fertilizers and compound fertilizers in rotation. The choice of humic acid fertilizer humic acid fertilizer can improve the utilization of phosphorus, potassium and some trace elements in soil. Humic acid fertilizers have a synergistic effect on phosphorus and potassium. Based on the application of humic acid fertilizers, the amount of chemical fertilizers can be appropriately reduced, generally about 1/3, and humic acid fertilizers commonly used in vegetable production are nitro-humic. Acid, ammonium humate, sodium humate, potassium humate, potassium nitroguanamate, diammonium fulvic, phosphoric acid fulvic, etc., vegetable farmers can choose to apply. The total water-soluble fertilizer is selected to use less water-soluble fertilizer, and only 10 to 15 pounds of sheds can be used for an acre of land, and the utilization rate is as high as 85%, which can supplement the nutrients needed for the crops and be used in rotation with biological bacterial fertilizers.
