How long does it take for fertilizer to be fully absorbed into the ground? Why?

Different fertilizer crops have different absorption rates. Compound fertilizer.

Decomposes slowly, and crops absorb it for life; Urea.

It needs to be transformed, and it can be absorbed in about 15 days; Ammonium bicarbonate.

Rapidly absorbed within a week; Foliar fertilizers can be absorbed within a few hours.

1.Generally, the fertilizer will work two hours after it is applied to the ground, but it will also delay the effect. For example, when we have a drought and it doesn't rain for a long time, the action of fertilizer slows down and delays the action.

The reason is that the land is relatively dry, and the fertilizers applied to the land do not absorb our crops quickly.

2.Usually, chemical fertilizers are applied to the soil and decompose into ionic states such as ammonia and nitric acid when exposed to water.

Ammonia, potassium oxide and phosphorus pentoxide.

It takes a week for crops to be absorbed and utilized. There are many types of fertilizers. Different fertilizers have different absorption times after spraying on the ground. In general, ammonium bicarbonate can be absorbed on the same day after spraying, ammonium chloride.

It takes about 3 days for fertilizer to be absorbed, urea for about 7 days, compound fertilizer for about 10 days, and biofertilizer for about 30 days.

3.If you want it to dissolve quickly.

1) Use ammonium bicarbonate and ammonium chloride fertilizers.

Ammonium bicarbonate: effective on the same day, fertilizer effective period of 15 days; Ammonium chloride: effective in three days, fertilizer effective period of 25 days, later fertilizer removal; Urea.

7 days onset, fertilizer effective period 45 days; Compound fertilizer: effective for 10 days, fertilizer effective for 90 days; Biological fertilizer: generally effective in about a month, the effect on crops with a long growth cycle is not very obvious, but the fertilizer effect can last for 6 to 8 months; Hormones:

The results are fast, but there is not much nutrition, and it does not help much in increasing production. In fact, chemical fertilizers need to be long-term**. It is best to apply according to the physiological characteristics of the crops at each stage.

There's no need to blindly pursue fast availability.

2) Fertilize on rainy days.

We try to choose rainy days when applying fertilizer. In both cases, fertilization works best, and our fertilizer can be fully absorbed by the crop. After rainfall, fertilizer and rainwater can be fully combined and fully absorbed by the crops in about two hours.

4.The amount and degree of absorption are closely related to the environment and the water solubility of fertilizers. For example, the crystalline form is easier to inhale plants than the powder form.

It takes about 5 to 10 days to absorb it. Because these fertilizers need to undergo a series of transformations so that they can be absorbed by the crops.

This fertilizer should be distinguished, if it is a farmhouse fertilizer, it will take about 5 days to be absorbed and utilized by plants, if it is a fertilizer, it is generally effective every other day, because the fertilizer effect of chemical fertilizer is very fast.

It's about 15 days, pay attention to the amount when fertilizing, don't apply too much fertilizer at one time, be sure to water in time, pay attention to the temperature, and don't have particularly serious compost.

This depends on the condition of the soil, which will be fully absorbed within a few days, because these things will melt when exposed to water and can be quickly absorbed by plants.

15 days to a month. Because some fertilizers have different compositions, the digestion time of fertilizers in the field is not good.

How long does it take for fertilizer to work in the soil? This question is really hard. There is a transformation process when fertilizer is applied to the soil, and there is also a process from absorption to utilization of crops, and it is affected by the natural environment.

The impact is larger. The effect mentioned here refers to the absorption of crops, and only the absorption of crops has an effect. If you look at the theoretical data from the laboratory, whether it is organic fertilizer or inorganic fertilizer, whether it is a simple chemical fertilizer or compound fertilizer.

may have a time-specific effect. But when fertilizer is put into the soil, it is difficult to say how quickly it can be absorbed by crops due to the interference of various factors.

<>We all know that melted fertilizer is absorbed by crops, which has a lot to do with temperature and soil moisture. For example, the fertilization efficiency in winter and summer is not the same, after fertilization, watering or not, or the amount of rain, soil moisture has a great impact on fertilization efficiency. In addition, the variety and nature of fertilizers are different, and the melting time and fertilization effect of each fertilizer are also different.

After fertilizer is applied to the soil, whether the crop can be quickly absorbed and utilized is also a problem, and the effect will not be seen without absorption. Although the fertilizer applied is good, the soil environment is poor, the crops can not absorb well, or due to the antagonism between the fertilizer elements, or the crop roots do not absorb well, and the nutrients of the fertilizer cannot be effective. For example, orange soluble phosphate fertilizer is difficult to melt when applied to alkaline soils in the north, while acidic soils in the south melt soils that have been absorbed by crops.

In short, for the question of how long the fertilizer can be effective in the soil, because the fertilizer into the soil, the influence of various factors is relatively large, it is not easy to generalize, and it needs to be analyzed on a case-by-case basis.

Do a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me more, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

I think it takes about 10 days to see results, because fertilizer is very important for plants, and the amount of fertilizer can also determine the growth rate of a plant, so I think it takes about 10 days to see results.

I think it can be effective in 9-15 days, and it depends on the soil temperature, humidity, and fertilizer quality.

It will take about three days. Because during this period, the fertilizer will slowly take effect, and it will have an impact on the plant.

Summary. Dear, I'm honored to have your question The information that the teacher found for you here is: how long does it take to fertilize the vegetables to absorb the time when the fertilized vegetables can absorb it; Water-soluble fertilizer vegetable fields can generally be absorbed in 10-15 days, and the fertilizer effect can also reach 20 days when the fertilizer effect is longer.

Generally, leafy vegetables have a short growth cycle and small fertilizer requirements, so they can be applied 2-3 times of water-soluble fertilizer, while eggplant fruits, such as cucumbers, tomatoes and other vegetables that can be harvested many times, require a large amount of fertilizer, and 1-2 times of water-soluble fertilizer can be applied at the seedling stage, and more than 3 times in the middle and late stages of fruiting. Generally speaking, vegetables can be picked and eaten on the same day after fertilization, as long as they are cleaned. However, in order for the nutrients in the fertilizer to be completely absorbed by the vegetables, it is better to eat after 7-10 years of fertilization.

It can last for several months because manure can ferment in the soil, and it can ferment for a longer time.

The duration of manure effectiveness in the soil depends on several factors, including the composition of the manure, the type of soil, climatic conditions, and the type of crop.

In general, if the organic matter in manure decomposes slowly in the soil, then it will last longer. Under ideal conditions, the fertilization effect of manure in the soil can last for more than a year. However, due to the low nutrient content in manure, there may be significant defertilization and nutrient deficiency in the later growth stage of crops.

Therefore, in order to ensure the normal growth of crops, fertilizer supplementation is required at the right time.

The fertility of organic fertilizer is not very large, and generally only lasts for about one to two months, but if you use chicken manure, it can last for about three months.

After manure is applied to the soil, it will show a certain fertilizer response for a certain period of time, which is that the free nutrients in the manure are absorbed and utilized by the roots. When the free nutrients are depleted, crops will show certain slowing growth, similar to the symptoms of defertilization, the main reason is that the decomposition rate of organic matter is too slow, and the release of nutrients is too limited to meet the needs of crop growth.

<> compound fertilizer sprinkled in the ground generally has a fertilizer effect period of about 90 days. Precautions for using compound fertilizer: compound fertilizer containing nitrate cannot be used on leafy vegetables and paddy fields; Compound fertilizers containing ammonium ions should not be applied on saline-alkali land; Compound fertilizers containing potassium chloride or chloride ions cannot be used in chlorine-free crops or saline-alkali land; Compound fertilizers containing potassium sulfate should not be applied in paddy fields and acidic soils, otherwise it will not only affect the fertilizer efficiency, but also may poison crops.

1. How many days does the fertilizer effect of compound fertilizer sprinkle in the ground?

1. The compound fertilizer is sprinkled in the ground for about 10 days and takes effect, and the fertilizer effect period is about 90 days. Compound fertilizer has a long effect, should be used as base fertilizer, due to the slow decomposition of compound fertilizer, for crops that use compound fertilizer as base fertilizer when sowing, it should be supplemented with available nitrogen fertilizer in time according to the fertilizer demand law of different crops in top dressing to meet the nutritional needs of crops, and the concentration of compound fertilizer varies greatly, and attention should be paid to choosing the appropriate concentration.

2. When using compound fertilizer, it should be noted that compound fertilizer containing potassium chloride or chloride ions cannot be used on chlorine-resistant crops or saline-alkali land; Compound fertilizers containing nitrate cannot be used on leafy vegetables and paddy fields; Compound fertilizers containing potassium sulfate should not be applied in paddy fields and acidic soils, otherwise it will not only affect the fertilizer efficiency, but also may poison crops. Compound fertilizers containing ammonium ions should not be applied on saline-alkali land; Different brands and different concentrations of compound fertilizers use different raw materials, and the production should be selected according to the type of soil and crop types. In addition, when choosing compound fertilizers, you should also pay attention to the nutrients contained in it, as well as the packaging and manufacturer, and beware of being deceived.

Second, the advantages of compound fertilizer

1. The total amount of nutrients of compound fertilizer is generally relatively high, and a single application of compound fertilizer can at least be used at the same time to produce more than two main nutrients, and there are many types of nutrients.

2. The structure is uniform, the nutrient distribution is relatively uniform, compared with the crystalline or powdery unit fertilizer after causing particles, the nutrient release is uniform, the structure is compact, and the fertilizer effect is stable and long, such as ammonium phosphate does not contain any useless side components, and its anions and cations are the main nutrients absorbed by crops. Due to the small number of side components, it has little adverse effect on the soil.

3. Compound fertilizer is generally made into particles, which is not easy to agglomerate, and has low hygroscopicity, which is especially convenient for mechanized fertilization.

4. Because the content of active ingredients in compound fertilizer is generally higher than that of unit fertilizer, and there are fewer by-components, it can save storage, packaging and transportation costs. For example, for every 1 ton of ammonium phosphate stored and transported, it is equivalent to a total of 4 tons of ammonium persulfate and calcium phosphate are stored and transported.

After applying flush fertilization, it can be absorbed by crops after about 2-3 days or 3-5 days. Flushing fertilization is mainly used in the vigorous growth season of vegetables and other crops when topdressing, it is generally widely used in trembling greenhouse planting and front-digging open field planting vegetables, because of its fertilizer effect is relatively fast, so in recent years, the use of flushing fertilization farmers are also more silver hole core.
