Applying undecomposed organic fertilizer to fruit trees does much harm, and it cannot be ignored
Organic fertilizer is also called farmyard manure. In fruit tree production, the commonly used types 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 base fertilizer...

What is the correct method for applying potassium fertilizer to vegetables?
How do you apply potassium fertilizer when growing vegetables? What should you pay attention to? Potassium is one of the three essential fertilizer elements. Many vegetables need more potassium than nitrogen or phosphorus. Well-grown vegetables contain potassium at 2.5%-7% of their dry matter, higher than their nitrogen and phosphorus content. Most vegetables absorb more potassium than nitrogen. For example, cucumber absorbs nitrogen...

The Correct Method of Applying Potassium Fertilizer to Sunflowers
How Should Potassium Fertilizer Be Applied to Sunflowers? What Should Be Noted? As a food and oil crop, sunflowers are grown on an ever-expanding area in China and are widely distributed. Because sunflowers have a pronounced potassium-loving habit, in order to strive for high yields, besides applying a certain amount of nitrogen and phosphorus fertilizer, attention must also be paid to applying potassium fertilizer. But many farmer friends in actual...

Methods for applying herbicides to wheat to prevent freeze-related herbicide injury
What herbicide is best for corn planting? Corn plants that preferably do not suffer herbicide injury are relatively sensitive to herbicides, so they should be chosen reasonably to avoid herbicide injury. For soil treatment, 40% atrazine-acetochlor aqueous suspension emulsion has high herbicidal activity, a long application period, and is safe for corn and subsequent crops. Before emergence after sowing or after emergence when weeds...

How to Increase Yield by Applying Potassium Fertilizer Reasonably to Chinese Cabbage
How can Chinese cabbage increase yield by applying potassium fertilizer? The yield-increasing effect of applying potassium fertilizer to Chinese cabbage is obvious. Test results show that: under the same conditions of nitrogen and phosphorus fertilizer, adding potassium fertilizer (50% potassium sulfate) at 18 kg/mu to Chinese cabbage gave a yield increase rate as high as 33.2%, with an average increase of 159 kg of Chinese cabbage per kg of potassium sulfate. It enhances disease resistance. Applying potassium fertilizer can...

What are the precautions for applying biological potassium fertilizer?
How should cotton be supplemented with potassium fertilizer? For supplementing cotton with potassium fertilizer, it is generally best to use coarse fertilizer as a base dressing. At present, returning straw to the field should be strongly advocated. According to surveys, returning about 800 kg per 667 sq m can not only return 4 kg of potassium oxide to the soil, but also convert slowly available potassium in the soil into available potassium. Potassium fertilizer...

What are the precautions for applying urea to farmland?
What should be noted when applying urea to farmland? Please explain: urea is convenient to use and has high fertilizer efficiency, making it a nitrogen fertilizer much loved by farmers. It can be used as a base fertilizer, a topdressing, and also as a foliar topdressing. If applied improperly, it not only wastes fertilizer but can also cause "fertilizer burn" and harm crops. Therefore, when applying urea...

What points should be noted when applying phosphate fertilizer?
What effect does nitrogen fertilizer have on wheat? Please explain that among the elements required for wheat growth and development, nitrogen has the greatest impact on wheat grain quality, and its grain yield and protein content depend to a large extent on the level of nitrogen supplied by the soil. If the supply is very sufficient throughout the entire growth period of wheat, wheat will be both high-yielding and high in protein...
