How many days do you see results after applying potash? How long is the nitrogen and potassium top d

The validity period of nitrogen and potassium topdressing is about 7 to 8 days. It mainly promotes the growth of branches and leaves, and can improve the plant's absorption of nutrients. However, if too much nitrogen fertilizer is applied, it is easy to cause the plant to grow branches and leaves without flowering.

The plant will become slender and weak, and it will also affect flowering and fruiting. Therefore, when applying nitrogen fertilizer, the dosage must be controlled, not too much at a time, and not too often, to avoid fugitiveness.

Summary. The correct use time of potassium fertilizer 1, potassium fertilizer can be used as base fertilizer, top dressing, and foliar fertilizer, the specific use time needs to be determined according to the potassium content in the soil, the type of crop, and the growth period of the crop. 2. Generally, when the potassium content in the soil is less than 100-150mg kg, 5kg of potassium oxide is applied per mu, and when the potassium content in the soil is higher than 150mg kg, there is no need to apply potassium fertilizer, or a small amount of potassium fertilizer.

3. Watermelon is generally about a week after fruiting, when the fruit grows to the size of an egg, apply potassium fertilizer, which can increase the sugar content in watermelon and increase the yield of watermelon. 4. Before sowing soybeans, potassium fertilizer needs to be added to the base fertilizer, and about 10kg of potassium chloride or potassium sulfate is applied per mu.

Watermelon is generally about a week after fruiting, when the fruit grows to the size of an egg, apply potassium fertilizer, which can increase the sugar content in watermelon and increase the yield of watermelon.

4. Before sowing soybeans, potassium fertilizer needs to be added to the base fertilizer, and about 10kg of potassium chloride or potassium sulfate is applied per mu.

The duration of potassium fertilizer depends on the amount of potassium in the soil, the type of crop, and the period when the crop is growing. Potassium fertilizer can be applied when the potassium content in the soil is less than 100-150 mg kg. Potassium fertilizer can also be applied when cucumber and watermelon are in the fruiting stage, and rice is in the peak tillering stage and young panicle differentiation stage.

5. Potassium fertilizer is generally applied to rice at the peak tillering stage and young panicle differentiation stage, and potassium chloride fertilizer is generally applied per mu to promote the growth of panicles. 6. Cotton is generally sprayed with potassium fertilizer on the foliar surface in early August, and the potassium dihydrogen phosphate used per mu is diluted to 2% with water, and sprayed once every 1 week. 7. Cucumbers should be sprayed with potassium dihydrogen phosphate foliar fertilizer at a concentration of potassium dihydrogen phosphate during the fruiting period.

8. Fruit trees generally apply potassium fertilizer from June to August, and apply 1kg of pure potassium fertilizer per 100kg yield, and can choose to spray potassium dihydrogen phosphate foliar spray.

Okay thank you. Okay dear!

In general, it takes about 5-7 days to take effect after applying potassium nitrate fertilizer and potassium sulfate fertilizer, about 3 days for potassium chloride fertilizer to be effective, and about 1-2 days for foliar potassium dihydrogen phosphate fertilizer to be effective. The time to effect will be affected by factors such as the way it is used, the surrounding environment, etc.

1. Potash fertilizer is effective in a few days

1. The effective time of potash fertilizer depends on the way of use, the type of fertilizer and the surrounding environment, if potassium nitrate fertilizer and potassium sulfate fertilizer, it generally takes about 5-7 days to take effect, if potassium chloride fertilizer, it generally takes about 3 days to take effect, if it is foliar spray potassium dihydrogen phosphate fertilizer, it can be effective in about 1-2 days.

2. When applying fertilizer, if the surrounding ambient temperature is relatively high, the effect time of fertilizer is relatively fast.

3. When applying fertilizer, the fertilization method with effective time from fast to slow is foliar spraying, applied to water, and applied to soil.

4. Common potash fertilizers include potassium dihydrogen phosphate, potassium nitrate, potassium sulfate, etc. Among them, the fertilizer effect of potassium sulfate lasts for about 60 days, and is generally used as base fertilizer; The duration of potassium nitrate fertilizer effect is about 40-60 days; Potassium dihydrogen phosphate, if applied as a foliar spray, the fertilizer effect lasts for about 10-15 days, and if applied to the soil, the fertilizer effect lasts for about 40-60 days.

Second, the correct use of potash fertilizer

1. Soil fertility: generally when the potassium content in the soil is less than 100-150mg kg, 5kg of potassium oxide can be applied per mu, if the potassium content in the soil is higher than 150mg kg, there is no need to apply potassium fertilizer, or a small amount of potassium fertilizer.

2. Crop types: apply potassium fertilizer to potassium-loving crops such as leguminous crops, potato crops, sugarcane, sugar beet, cotton and linen, tobacco, corn, rice, etc.

3. Fertilizer selection: for tobacco, fruit trees and high cash crops, choose to use potassium sulfate, for fiber crops, choose to use potassium chloride, and for field crops, if they are not sensitive to chlorine, choose to use potassium chloride to reduce costs.

4. Fertilizer mixing: potassium sulfate and nitrogen, phosphorus and other fertilizers can be applied together, which can give full play to the fertilizer effect, if it is used in an acidic soil environment, potassium sulfate can be mixed with lime or phosphate rock powder. When potassium chloride is used in a sandy soil environment, it can be used in combination with organic fertilizers to enhance fertilizer efficiency.

5. Climate and production conditions: for rainy areas or areas with sufficient water sources for irrigation, potassium chloride is selected for areas with good drainage conditions.

<>1. The effect begins to take effect about 5-7 days after the soil is applied with potassium and fiber fertilizer. Foliar sprays of 300 times potassium dihydrogen phosphate have a faster effect (visible within 24 hours).

2. Potash fertilizer, the full name of potassium fertilizer. Fertilizers with potassium as the main nutrient generally account for potassium in plants, second only to nitrogen. In the process of plant growth and development, potassium is involved in the activation of more than 60 enzyme systems, photosynthesis, the transportation of imitation products, the metabolism of carbohydrates and the synthesis of proteins.

Summary. Potassium is a fertilizer with high potassium content, which is suitable for fertilizing a variety of crops. For transplanted plants at the seedling stage, appropriate fertilization should be started one week after transplanting to avoid premature fertilization causing damage to the plants.

Specifically, you can wait for a week or so after transplanting to observe the growth and nutritional status of the plant, and if the plant is growing normally and there is a need, you can start fertilizing the right amount. However, it should be noted that it should not be over-fertilized, and it should be controlled according to the needs of the plant and the amount of fertilizer used to avoid causing harm to the plant. In addition, as a fertilizer, the use method and dosage of potassium should be adjusted according to the growth characteristics and needs of different crops, and it is best to refer to the advice of agricultural professionals or fertilizer manufacturers for application.

Flush potassium can be fertilized a few days after transplanting.

Fertilization can be applied a few days after transplanting at the seedling stage.

Green energy is an organic nitrogen fertilizer, which is suitable for fertilizing various crops. For transplanted plants at the seedling stage, it is possible to wait about a week after transplanting to start fertilizing the appropriate amount, but the specific time should be determined according to the growth of the plant and the need for fertilizer. Generally speaking, an appropriate amount of fertilization can be applied about 7-10 days after transplanting at the seedling stage.

When fertilizing in Youliang, it should be controlled according to the needs of the plant and the amount of fertilizer residue used to avoid plant burns and damage caused by excessive fertilization. It is recommended to use diluted green energy fertilizer with a tap or sprayer to evenly cover the soil surface. In addition, fertilization should be synchronized with watering to maintain appropriate soil moisture to facilitate the absorption of nutrients by plants.

After fertilization, it is necessary to pay attention to the growth of the plant, and if excessive fertilization is found, the application of Shenchun fertilizer should be stopped immediately and appropriate adjustments should be made.

Compound fertilizer has long fertilizer effect, more types of nutrient code annihilation elements, can meet the needs of crops, and has the advantages of high nutrient content, less side components and good physical properties, which can improve crop yield and improve the quality of agricultural products.

Fertilizer effectiveness period of compound fertilizer: compound fertilizer varies greatly according to the moisture content of the applied soil and the composition of the fertilizer. Conventional compound fertilizer in dryland soil dissolves slowly, fertilizer efficiency occurs slowly, fertilizer effect time is long, fertilizer effect period can generally reach 2 4 months; The dissolution in paddy field soil is fast, the fertilizer effect occurs quickly, and the fertilizer effect time is short, and the fertilizer effect period is generally 1 to 3 months.

The phosphorus in the compound fertilizer is susceptible to soil mass fixation, and has a long after-effect period, and the orange in the current season can not be fully utilized, and it can also provide the absorption and utilization of crops. At present, there are also long-acting slow-hail land-release compound fertilizers, which can be formulated according to the needs of crop growth, and can be made into 1 or 2 years of effective fertilizer effective period. I wish you a happy life!

Hope mine is helpful to you ha.

How long is the expiration date of compound fertilizer in the soil?

The effective period of kiss fertilizer can generally reach 2 to 4 months.

Put it in the eucalyptus tree.

Doesn't most of them say that it takes more than half a year to absorb the fertilizer?

for. Kiss, this depends on the specific situation, if you feel that the plant is lacking nutrients, you should supplement it in time. Different crops and growth stages have different requirements for nutrients, so when using compound fertilizer, it is necessary to apply fertilizer reasonably according to the needs of crops and soil conditions to avoid excessive fertilization or insufficient nutrients.

At the same time, it is also necessary to inject the type and imitation ratio of compound fertilizer, and choose the compound fertilizer product that is suitable for you.
