What are the scientific application methods for bio-organic fertilizers?
How should nitrogen fertilizer be applied to fruit trees? Please provide guidance. If there is too much nitrogen in the fruit tree, it will cause an imbalance between carbohydrates and nitrogen in the tree or disrupt its relationship with other elements, resulting in excessive vegetative growth, spindly branches and leaves, poor flower bud differentiation, and serious flower and fruit drop; in summer and autumn, when the nitrogen content in fruit leaves exceeds 2....
How should bio-organic fertilizers be applied scientifically? Please provide an introduction and guidance.The application of bio-organic fertilizers can refer to the following methods:
1. Apply the right amount. The organic matter and other nutrient contents of bio-organic compound fertilizers vary according to each company's production standards. When applying, both the nutrient content of the fertilizer formula and the soil texture and fertility should be considered to determine the application rate. Generally, the amount used per 667 sq m (1 mu) is about 50 kg. For plots with poor soil texture and low fertility, use appropriately more; otherwise, reduce accordingly.
2. Apply at the right soil moisture. Under long-term drought weather conditions, it is not suitable to force the application of bio-organic compound fertilizers. Wait until after rain when the soil moisture is moderate, then apply. The standard for suitable soil moisture is: field soil can be formed into a ball by hand and breaks apart when dropped to the ground.
3. Apply in a mixture. Bio-organic compound fertilizers include general-purpose and special-purpose types. To reflect both quick-acting and long-lasting effects, they should be mixed with quick-acting chemical fertilizers, especially with high-content compound fertilizers for the best effect. Depending on different crops, fertilizers containing potassium, boron, zinc and other macro- and micro-elements can also be applied separately, which gives even better results.
