The results are obtained: in the same area, the amount of product usage is different, which effect is the best and the input cost per mu is more reasonable.

Look at what you've planted. Generally, there should be two to three times of plantar fertilizer and top dressing. Gymboree microbial fertilizer is OK.

10,000 acres of farmland with 80 catties of fertilizer, how many tons are needed in total.

Pro: 3000 tons. This question requires knowing the weight of each bag of fertilizer in order to calculate how many tons of fertilizer are needed in total. If the weight of each bag of fertilizer is 80 catties, then it can be calculated as follows:

The weight of a pack of fertilizer is 80 kilograms, which translates to 40 kilograms in kilograms (1 kilogram equals kilograms). The amount of fertilizer needed for 10,000 acres of farmland can be calculated according to the amount of fertilizer applied and the amount of fertilizer used. Assuming that 300 kg of fertilizer needs to be applied per mu of farmland, then the total amount of fertilizer required is:

10,000 mu 300 kg mu = 3,000,000 kg converts the total amount of fertilizer needed into tons, which can be divided by 1,000. Therefore, the total amount of fertilizer needed for 10,000 acres of farmland is: 3,000,000 kg 1,000 = 3,000 tons Therefore, 10,000 acres of farmland needs 80 kilograms of fertilizer for a total of 3,000 tons.

<> how much fertilizer needs to be applied per mu is generally related to the type of agricultural objects planted, the fertility of the soil, the design yield and other factors, taking rice planting as an example, a hectare balance Zen needs to apply about 50 kg of compound fertilizer per mu, and the specific amount of fertilizer should be determined according to the cultivation area to ensure the normal growth of rice.

Summary. Hello dear, every 100 kilograms of corn grains need to absorb about 2 kilograms of nitrogen fertilizer, kilograms of phosphate fertilizer, and potassium fertilizer. The actual fertilization ratio of nitrogen, phosphorus and potassium is approximately.

Grow corn on an acre of land with a compound fertilizer with a content of 42% nitrogen, phosphorus and potassium, and how much to put down.

Hello dear, every 100 kilograms of corn grains need to absorb kilograms of nitrogen fertilizer, phosphate fertilizer, and about 2 kilograms of potassium fertilizer. In fact, the proportion of nitrogen, phosphorus and potassium boiling liquid is approximately.

The yield per mu is 750 kg, so you can calculate how much to use.

The experts of the whole thing will not forget it.

I asked you how much fertilizer is used for an acre of land, and you gave me a question.

It's nothing. 50 kg of nitrogen, phosphorus and potassium compound fertilizer can be used in one bag per acre. Corn planting is 50-70 catties of ground fertilizer per acre.

Corn planting per acre with 50 kg of 45% compound fertilizer. Fifty kilograms of corn bottom fertilizer were applied to one acre, if it was a compound fertilizer, if it was a chemical fertilizer such as urea, it would be excessive, and generally urea should be within 15 kilograms per mu. 80 kg of compound fertilizer with slightly higher nitrogen content per mu of corn is about the same.

20 kg of diammonium phosphate per mu or 30 kg of organic fertilizer per mu are used as base fertilizer for corn planting. In fields with a yield level of more than 800 kg, 16-18 kg of nitrogen fertilizer, 6-8 kg of phosphate fertilizer, 5-8 kg of potassium fertilizer, 1-2 kg of zinc sulfate, and 1-2 kg of borax per mu are recommended. Corn planting is generally about 50 kg of nitrogen fertilizer per mu.

One acre of corn can be used with 80 kg of base fertilizer. Corn planting per mu is applied with 1000kg of agricultural model stove manure and 40kg of compound fertilizer.

Answer: It is suitable for planting flowers with high commercial value, and the organic matter content of the garden soil or cultivation substrate should reach more than 4% 5%. If it has been reached, it is only necessary to replenish the amount consumed by the mineralization of organic matter each year.

In general, the soil organic matter content is about tons of hectares, and the annual mineralization rate is about 2%, and tons of hectares should be replenished every year. For example, if the organic matter content of compost is 15%, then tons of compost should be applied per year. To increase soil organic matter content, the amount of organic fertilizer must be higher than the amount of organic fertilizer used to supplement the annual mineralization rate.

However, the amount of supplementation should be gradual, and it is better to increase it every year.

Here's an example for reference:

1.Studies on the nutritional characteristics of maize have shown that for every 100kg of corn grains produced, the proportion of nitrogen, phosphorus and potassium absorption in spring maize is about 1::, and nitrogen (N) phosphorus (P205) and potassium (K20) 5 6kg need to be absorbed; Summer maize needs to absorb nitrogen (N), phosphorus (P205) and potassium (K20), and the absorption ratio of nitrogen, phosphorus and potassium is 1::

Around. Compared with summer maize, the uptake of nitrogen and phosphorus in spring maize was more concentrated and the absorption peak was earlier. Generally, nitrogen uptake in spring maize only accounts for the total at the seedling stage (before jointing), in the middle stage (from jointing to heading and flowering), and in the later stage (after heading).

The nitrogen uptake of summer maize at the seedling stage, the middle stage, and the late stage. Phosphorus absorption in spring maize, which accounts for the total absorption at the seedling stage, in the middle stage and in the late stage. Phosphorus absorption accounted for in the seedling stage of summer maize, 80% in the middle stage, and 80% in the later stage. The absorption of potassium in maize increased rapidly after jointing in spring and summer, and reached a peak in the flowering stage, and the absorption rate was large, which could easily lead to insufficient potassium supply and potassium deficiency symptoms.

2.Fertilization technology according to the law of nutrient absorption during the growth period of corn, the fertilization principle of corn is: apply sufficient base fertilizer, light seedling fertilizer, heavy application of jointing fertilizer and bud fertilizer, skillful application of grain fertilizer.

1) Base fertilizer: The base fertilizer is mainly organic fertilizer, and about 3000kg of organic fertilizer is generally applied per mu. About 30 40ks of superphosphate per mu were applied to phosphorus-deficient soil, and 5 10kg of potassium chloride per mu were applied to potassium-deficient soil.

Generally, late-acting fertilizers account for about 80% of the total amount of base fertilizers, and fast-acting fertilizers account for about 20%. The base fertilizer can be applied deep in the whole layer, and when the amount of fertilizer is small, the method of furrow application or hole application can be used. Cropping or mixed cropping corn should pay attention to the use of seed fertilizer, - general use of organic fertilizer, with an appropriate amount of nitrogen and phosphorus fertilizer, the use of strip application or hole application method.

2) Top dressing: When the amount of fertilizer per mu is less than 20kg of standard nitrogen fertilizer, it is advisable to top dressing once in the middle of jointing, and the stalks and ears should be attacked together. Generally, about 30 days after sowing of early-maturing varieties, that is, the "bell mouth stage", top dressing is better.

About 25 days after sowing of medium-ripe varieties, top dressing is good. Late-maturing varieties are sown 35 to 40 days after sowing, and top dressing is good. If the amount of standard nitrogen fertilizer per mu exceeds 20kg, it is better to top dressing in stages.

The focus is on tapping stalks and ear fertilizers, supplemented by seedling lifting and seed fertilizers. The results of the test in various places, the use of secondary top dressing, generally before the heavy after the light, that is, the stalk fertilizer accounted for 60% 70%, the ear fertilizer accounted for 30% to 40% as well, high fertility field or the application of base fertilizer, seed fertilizer, seedling fertilizer, then the previous light and heavy is better. For some soils deficient in trace elements such as zinc, iron, boron, etc., zinc sulfate or borax solution sprayed at jointing and booting stages has a significant yield increasing effect.

Depending on what crops are planted, if you want to have a high yield, you can apply more, 500 kg for general cash crops, and 5 tons for more, but the yield and quality are also unexpectedly high, if you want to do it, I can teach you.

The amount of organic fertilizer does not need to be very strict, the appropriate amount of fertilizer can be used!

The amount of compound fertilizer per mu is generally about 40-70 catties, and the specific amount of fertilizer generally depends on the type of crop, the fertility of the soil, the expected yield and other factors. Generally, the nutrient content of different types of compound fertilizers is also different, and because individual fertilization methods will be different, there is no absolute application amount of compound fertilizer when the above conditions cannot be determined.

The amount of <> compound fertilizer per mu is generally about 40-70 catties, and the specific amount of fertilizer generally depends on the type of crop, the fertility of the soil, the expected yield of Tuantong and other factors. Generally, the nutrient content of different types of compound fertilizer is not the same, and because the individual fertilization method will be different, so in the case that the above conditions can not be determined, the compound fertilizer does not collapse and has an absolute application amount.
