What are the commonly used types of organic fertilizer in fruit tree production?
Organic fertilizers, also known as farmyard manure, commonly used in fruit tree production include compost, pen manure, stable manure, green manure, cake fertilizer, river mud, poultry manure, human feces and urine, and miscellaneous soil manure. Most organic fertilizers need to be decomposed by microorganisms before they can be absorbed by the plant's root system, so they are also called "slow-release fertilizers" and can be applied as a base fertilizer...

Which fertilizers cannot be mixed in agricultural production?
Pure urea is a white crystalline solid, while the industrial product is small white or pale yellow granules, with a nitrogen content of 44-46%. It is only slightly hygroscopic, easily soluble in water, and is a neutral fertilizer; it has the highest nutrient content among solid nitrogen fertilizers. Because it is absorbed quickly through the leaves and has a high utilization rate, its yield-increasing effect is great, making it most suitable for foliar topdressing. The spraying concentration should be based on...

Organic fertilizer application requires careful attention; the same fertilizer can produce very different results
Frost's Descent (Shuangjiang) brings the breath of early winter. Frost's Descent falls in the transition period between autumn and winter; as it arrives, the weather fluctuates considerably, gradually turning colder and frost beginning to form.

What issues need attention when urea production surges?
How can urea application improve utilization efficiency? Please guide deep application. Whether urea is used as a base fertilizer or a top dressing, it should be applied deep and covered with soil, with an application depth of 10-12 cm being appropriate. Deep application of urea can significantly improve utilization efficiency. According to experiments, when urea is surface-applied or shallow-applied at 2-3 cm, the utilization rate is only 30%; at an application depth of 5 cm, the utilization rate is 45%...
