What happens when the soil turns green after using flush fertilizer

The soil turns green after using flush fertilizer because the fertilizer is uneven, and the fertilizer is not watered in time, so that the fertilizer dissolves into the soil and is absorbed by plants.

The main advantages of flush fertilization are as follows:

1. Improve soil exchange capacity.

Humic acid in water-soluble fertilizer has a high cation transition, which is more than 10 times higher than that of general soil. After being applied to the soil, the soil has a significant ability to adsorb anions, and the salt content of the surface layer is reduced.

2. Promote the formation of soil aggregates.

Soil aggregates are the basic units of soil structure. The use of humic acid water-soluble fertilizer can change the physical and chemical properties of high salt content, strong alkalinity, high dispersion of soil particles and poor soil structure in the soil, promote the formation of soil aggregates, and make it into a good state, so as to create good conditions for the growth and development of plant roots.

3. Reduce the salt content of the topsoil.

The application of humic acid water-soluble fertilizer can loosen the soil of the cultivated layer, destroy the accumulation of salt, reduce the salt content of the topsoil, play the role of salt isolation, improve the seedling emergence rate, reduce weak seedlings and dead seedlings, and make the plant grow healthily.

4. Reduce the pH of saline-alkali soil.

Flushing fertilization can neutralize alkalinity, reduce and eliminate the harm of alkalinity to soil and plants, improve low-yield saline-alkali land, and create good soil conditions for the growth of crop seedlings.

If the soil only turns green on the skin, it is generally moss growing under high temperature and humidity conditions, which is a normal phenomenon and there is no need to worry.

If the soil also turns green below the surface, it should be that the greenhouse soil is more acidified. Due to the frequent use of iron-containing micro-fertilizers, iron is enriched, and after the soil is washed with fertilizer, iron is reduced to divalent iron ions, which appear dark green. In this case, lime or alkaline soil conditioner can be used appropriately to adjust the physical and chemical properties of the soil.

Hello dear, the compound fertilizer water sprinkled in the field turns dark green, which may be caused by the high ammonium nitrogen content of the compound fertilizer or improper fertilization method. The method of processing is as follows:1

Watering in moderation: Soak the soil in the field in a suitable amount of water to dilute the excess nitrogen. 3.

Apply more fertilizers containing phosphorus and potassium: Phosphorus and potassium are also important for plant growth, which can increase the appropriate amount of phosphorus and potassium.

Do plants like fertilizer.

In general, the need for fertilizer in various periods of this plant is not great and frequent. Of course, if you want it to grow stronger, or if you are not satisfied with the fertility of the soil, you can apply a little more, but you must pay attention to the dosage. After all, there is not much demand for this plant itself.

What fertilizer to apply.

This plant does not have any special requirements for fertilizer, ordinary cake fertilizer and water will do. However, it is important to note that fertilizers need to be diluted before they can be used by plants.

How to deal with it.

When the plant is in full bloom, you can choose to fertilize it every two months. If the soil you choose is poor, you can also use fertilizer every other month. However, it should be noted that the frequency should generally not be too high.

Plants generally do not grow in summer, so do not fertilize them at this time. The remaining one is winter. At this time, because the weather is too cold, the plants have no desire to grow, so the treatment of this silver file time is the same as in summer, and the fertilization can be stopped.

Issues that should be noted.

In order to avoid too much trouble with artificial fertilizer in the later stage, you can pay attention to it when selecting soil. We can mix humus, culture soil, and sediment, and we can also add some bone meal, which is more beneficial to the plants. Another point is that when we apply liquid fertilizer to plants, we must be careful not to sprinkle them on the plants, otherwise the part involved may slowly rot.
