What Types of Nitrogen Fertilizers Are There? A Detailed Guide to Application Methods
The nitrogen fertilizers commonly used in fruit tree production mainly include urea, ammonium bicarbonate, ammonium nitrate, ammonium sulfate, ammonium chloride and slow-release urea. Urea is an amide-form nitrogen fertilizer with a nitrogen content generally of 46%, and can be used as a base fertilizer, a top dressing and a foliar top dressing. Ammonium bicarbonate is an ammonium-form nitrogen fertilizer with a nitrogen content generally of 16.5%-16.8%, and can be used as a base fertilizer, ...

Smart ways to use nitrogen fertilizer: economical and efficient application
1. Good nitrogen retention. Changing nitrogen fertilizer from surface application to deep application can greatly reduce volatilization losses and denitrification. It reduces fertilizer consumption by weeds and algae, giving nitrogen fertilizer a good nitrogen-retention effect. Apply nitrogen fertilizer 7--9 cm deep. According to measurements, when ammonium bicarbonate spherical fertilizer is applied deep, 30 days after fertilization the nitrogen loss is 3...

Correct application methods and precautions for slow-release nitrogen fertilizer
Traditional nitrogen fertilizer management for strong-gluten wheat is generally divided into two applications. The first is a portion of nitrogen fertilizer applied before wheat sowing in conjunction with plowing, accounting for 60%-70% of the total nitrogen application; the second is a topdressing applied from the spring green-up stage to the stem elongation stage of wheat in conjunction with watering, accounting for 30%-40% of the total fertilizer application. Some apply it before wheat overwintering...

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....
