Why soil fertilization requires consideration of the time, location, depth of fertilization

Nowadays, there are more and more soil problems, and we consider the reasons for time, location, and depth when fertilizing the soilIn order to improve fertilizer efficiency, improve the soil and maximize the absorption of fertilizer by the soil.

1. Comparison of different fertilization methods

1. Surface fertilization.

Surface fertilization is generally not recommended, because surface fertilization is easy to allow weeds and other plants to absorb nutrients, and it is easy to lose with rain, resulting in reduced fertilizer utilization. Surface fertilization is mostly to meet the needs of fertilizer at the seedling stage of crops, and the shallow application of plant root distribution at this time is more conducive to absorption.

2. Fertilization of the whole tillage layer.

Many areas are using the whole tillage fertilization technology, this fertilization method has certain advantages, because the fertilizer distribution in the tillage layer is evenly distributed to the extension of the root system of the plant in a period of time and the absorption of nutrients, the growth of crops is relatively uniform.

3. Layered fertilization.

Layered fertilization is to apply a part of the fertilizer to a depth of 10-20 cm below the tillage layer, and then apply the rest of the fertilizer to the tillage layer at a depth of 1-10 cm, and then stir well.

The depth of fertilization is well graspedIt can not only improve the utilization rate of chemical fertilizers, but also reduce the damage to the root system of crops, Hai and Wigan burst rooting agents can also be used to help crops root, which plays an important role in improving planting yields.

Second, the difference in fertilization time, method and location

1. Fertilization time includes the time suitable for fertilization in a day, there are differences in temperature and humidity in morning, noon and evening, it is recommended to avoid fertilization at noon when high temperature, high humidity and strong light, especially when fertilizing foliarly, which is conducive to avoiding damage to crop roots, shoots and leaves.

2. The better way is to drip irrigation under the film and bury it in the soil to cover, and the spreading effect is the worst! Only a few percent utilization.

Foliar topdressing is suitable for crop growth at the peak of the season, when the root system and transport system cannot provide sufficient nutrients in time, and when the medium and trace elements are appropriately and quickly supplemented.

3. The rhizome of the plant is often a thick root system, and the absorption capacity is limited, if the fertilization position is too far, it is not convenient to use it in the place where the root system is less. For different crops, the fertilization location should be determined according to the root distribution characteristics of their different growth stages, so as to facilitate crop absorption.

Of course, soil fertilization should take into account the time and position of strength, the depth of the time is just right, the position is just right, and the depth is just right, so that her fertilizer is very effective for the growth of seedlings, and the crops grow vigorously, and in the autumn, the grain is not full.

Summary. Due to the fertilization of the root system, the depth and breadth of fertilization can induce the growth direction of the root system.

Why is soil fertilization required to consider the timing, location, and depth of fertilization+?

Due to the fertilization of the root system, the depth and breadth of fertilization can induce the growth direction of the root system.

The timing of fertilization is to provide nutrients in time to promote growth when the crops are not sufficient.

Summary. Hello Plant roots are fertilisative, so the depth and breadth of fertilization can induce the growth direction of the roots, so the location and depth should be considered.

Why is soil fertilization required to consider the timing, location, and depth of fertilization+?

Hello Plant roots are fertilisative, so the depth and breadth of fertilization can induce the growth direction of the roots, so the location and depth should be considered.

The law of crop nutrient demand refers to the absorption characteristics of various nutrients such as nitrogen, phosphorus and potassium in different growth periods of crops, and the absorption of nutrients in different crops is not the same, and the absorption of different nutrient elements in each growth period of the same crop is also different, so it is necessary to consider the time of fertilization.

Dear, I hope mine is helpful to you

If you still have doubts, please feel free to consult

The fertilization period (excluding extra-root fertilization) is the same as the pruning period, in the two key periods of Dongkui bayberry cultivation and management throughout the year, that is, the first critical period is the management after fruit picking, and the second critical period is the management before the Spring Festival, that is, the winter management, in these two critical periods, the key work is pruning and fertilization, combined with other management work. The fertilization period of Dongkui bayberry can not be carried out casually, which is due to the reason that Dongkui bayberry has longevity, if the fertilization is improper, it will promote the tree body to germinate without a purpose, or the branches are vigorous, affecting flowering and fruiting.

The fertilization period of Dongkui bayberry should not be carried out casually, just as the pruning period in question 35 is determined. This is all because of the longevity of Dongkui bayberry. If the fertilizer is not applied properly, it will promote the untargeted germination of the tree, or the branches will flourish, affecting flowering and fruiting.

The fertilization period (excluding extra-root fertilization) is the same as the pruning period, which is in the two key periods of year-round cultivation and management of Dongkui bayberry, that is, the first critical period is the management after fruit picking; The second critical period is the management before the Spring Festival, that is, the winter management. During these two critical periods, the focus is on pruning and fertilization, combined with other management tasks.

About 10 cm.

A method of applying chemical fertilizers in the field. Nitrogen, phosphorus and potassium fertilizers should be applied deeply. Deep application of nitrogen fertilizer can prevent the volatilization of ammonia, prevent the escape of ammonia caused by denitrification in paddy fields, and reduce the impact of rainwater leaching and surface runoff.

Deep application of Trim phosphate fertilizer and potassium fertilizer can help crop root absorption. There are many ways to apply chemical fertilizer deeply, such as spreading fertilizer before ploughing, making base fertilizer after ploughing, and ditching and hole application during sowing, transplanting or growth period.
