How to apply fertilizer scientifically in hot and dry weather
It is not advisable to apply large amounts of undecomposed cake fertilizer. Cake fertilizer has a relatively small carbon-to-nitrogen ratio and decomposes quickly, easily generating high temperatures. Applying undecomposed cake fertilizer will raise the local temperature, cause root burn and affect seed germination, and will also attract underground pests. The cake fertilizer should be crushed and soaked in human urine until it heats up before application. Compound fertilizer cannot be used alone...

What are the precautions for combined fertilizer application
The solution made by soaking onion skins not only contains a substance that can kill pathogenic microorganisms in the soil, but also contains a variety of trace elements, and can be used as fertilizer for crops. 1. When growing flowers indoors, if the onion skin soaking solution is used as fertilizer, the flower branches grow luxuriantly and the flowers are more brightly colored. 2. Yellowing and withering cucumber seedlings are especially suitable for onion...

Detailed Explanation of the Characteristics and Functions of Common Fertilizers
In sandy soil, all phosphate fertilizer should be applied as a base fertilizer, half of the nitrogen fertilizer should be applied as a base fertilizer, and the other half should be applied as a top dressing in stages during the growth and development process. Then, the amount of irrigation water should not be too large, to avoid fertilizer loss caused by flood irrigation. In clayey soil, where irrigation conditions are available, phosphate fertilizer and 2/3 of the nitrogen fertilizer can be applied as a base fertilizer, and 1/3 of the nitrogen fertilizer can be applied as a top dressing in stages. Where there are no...

Reasonable Application Methods for Water-Soluble Fertilizers
Plants need to absorb various nutrients for growth and development. However, what determines crop yield is the nutrient factor present in the smallest relative amount in the soil, and yield also changes relatively within a certain limit as this factor increases or decreases. This is usually explained using a water-filled wooden bucket. The bucket is made of staves representing different nutrient contents and factors...

Which fertilizers cannot be applied by flushing? Fertilization taboos every grower must know
Flush fertilization is widely used on greenhouse and open-field vegetables, mainly for topdressing during the vigorous growth period of vegetables. But not all fertilizers can be applied by flushing; only water-soluble fertilizers can be applied by flushing with water. For nitrogen fertilizers, urea, ammonia water, ammonium sulfate and ammonium nitrate are commonly used; for potassium fertilizers, potassium chloride and potassium sulfate are commonly used, and potassium nitrate can also be used for flush...

Fertilizer packaging hides traps that cheat farmers; be vigilant when buying
Drying organic fertilizer for application: drying human and livestock manure causes flies and maggots to breed and loses the fertilizer's nitrogen nutrients. The correct method is to pile and compost the organic fertilizer until it is thoroughly decomposed and use it as a base fertilizer. For example, in late July, in a sunny spot, take 4,000 kg of human manure or chicken manure, add 100 kg of calcium magnesium phosphate fertilizer and 400 kg of chopped wheat straw, mix them, and pile the mixture into a steamed-bun shape, then cover it with plas...

Methods and Key Technical Points for Applying Phosphate Fertilizer in Orchards
In spring and summer, the periods before and after flowering of fruit trees are stages prone to various diseases (physiological diseases and pathogen toxin diseases). At this stage, in addition to necessary chemical prevention, timely application of phosphorus and potassium fertilizers is also a good choice. However, many fruit growers tend to apply only nitrogen fertilizers (such as urea, high-nitrogen...

What are the functions and effects of water-soluble humic acid fertilizers
Introduction to water-soluble fertilizer knowledge: Water-soluble fertilizers are more easily absorbed by crops. "Water-soluble fertilizer refers to a multi-element compound fertilizer that can completely dissolve in water. Compared with traditional varieties such as superphosphate and granulated compound fertilizer, water-soluble fertilizer has obvious advantages. Its main features are low dosage, convenient use,...

Water-soluble fertilizers are rich in nutrients, saving water and fertilizer while promoting growth with notable results
First, applying small amounts multiple times can improve the utilization rate of water-soluble fertilizers. If applied by flushing, generally about 10 kg per mu per application; if applied by spraying, generally dilute 500-800 times. Second, water-soluble fertilizers are generally used as topdressing, and the appropriate variety and amount of water-soluble fertilizer should be selected according to the amount of base fertilizer applied and the crop's growth condition. Third, for open...

Correct Application Methods for Water-Soluble Fertilizers
Water-soluble fertilizer (WSF) is a multi-element compound fertilizer that dissolves completely in water. It dissolves rapidly in water, is more easily absorbed by crops, and has a relatively high absorption and utilization rate. More importantly, it can be applied in facility agriculture such as spraying and drip irrigation, achieving...
