Does nutrient soil have an expiration date? Can the nutrient soil still be used after 3 years?

Nutrient soil has a shelf life! The shelf life of different configurations of nutrient soil is also different! Soil outside the shelf life will evaporate and lose its fertility.

Many pot lovers are obsessed with potted flowers and plants, and the nutrient soil for raising flowers.

It is also relatively easy to obtain, not only can you easily buy Ali back directly from the market, but you can also obtain it in a self-made way. But as a nutrient soil, how long can it generally be used? Can it be used repeatedly?

People who like to raise flowers have generally used nutrient soil, whether it is purchased or homemade, and some pot friends feel that the effect is very good. However, there are also many people who feel that the quality is too poor, not only the growth and growth of vegetative plants, but also easy to breed various pests and diseases, which has become a paradise for germs and insects. And many people like to choose the way of homemade nutrient soil, which seems to be really good.

High-quality nutrient soil can often be used for a long time, but how long it can be used mainly depends on the type of substrate medium selected and the ratio of various media, and it is also necessary to consider the intake of water and fertilizer and many other factors in the process of use. Therefore, there is no strict deadline and standard for how long the nutrient soil can be used. In short, as long as the nutrient soil is still relatively fertile and loose, it does not affect the air and water permeability at all, it can continue to be used.

Recently, I also went to the flower market to buy a package of so-called nutrient soil, and after using it, I found that there were germs, so that I almost raised my beloved Huahua to death. However, it also came to a conclusion: nutrient soil can not be directly used to raise plants, and it should be exposed to the sun in advance before use to sterilize and sterilize, or it can be stir-fried or other methods, as long as the purpose of sterilization can be achieved.

Moreover, when using nutrient soil directly, the substrate is often too light and loose, which is not conducive to stabilizing the plant, thus affecting its normal growth. If you water more, it is often more fatal for plants with succulent roots, because it is easy to rot roots, which seriously hinders the normal growth of plants.

In fact, it is precisely because the nutrient soil is too loose and light, it can usually be reused. As the new soil lasts for a long time, other sediments will increase, making the soil more abundant and fertile. This is more beneficial to the growth of flowers and plants, but it should be noted that even if it is used repeatedly, it is recommended to sterilize and disinfect it before use, so as to ensure that it is relatively clean, and it is safer to raise flowers and plants, and the plant will grow more robustly.

However, we also need to consider the compaction factors of the old nutrient soil, because the soil will gradually improve the soil structure due to the positive sediment after a long time, and if the old soil is directly used repeatedly, it is easy to compaction. We can appropriately add some other substances that are conducive to improving soil quality, especially delaying or avoiding soil compaction, which is very important for reusing old soil for flower cultivation.

The nutrient soil for raising flowers can generally be maintained for half a year, depending on the habits of the flowers. Some prefer fertilizer, after half a year, it is necessary to apply fertilizer and supplement fertilizer in time, so as to ensure that the nutrients are sufficient and the plant grows normally.

It is best to use it after fermentation, and if it is not used up in a short time, it should be packed in a bag with a better seal, because after a long time, mildew will suddenly occur, or the fertility of the soil will decrease.

After fermentation. If it is not finished in a short time, it should be packed in a bag with a higher seal, because it will suddenly become moldy or the soil fertility will decline after a long time.

Yes. After the use of nutrient soil collected, can be placed in the sun exposure, in general, we can be exposed to about three suns in urban greening, the purpose of exposure is to use ultraviolet sterilization and insecticidal eggs, the effect is very good, after a few days of exposure to the sun will generally be used again.

For the old soil, it needs to be used with caution, and generally cannot be directly used for new flowers and plants. First of all, we need to sterilize, sterilize, and exterminate insects, which can be put in the hot sun, or poured some carbendazim solution in the old soil, or even put it in a pot and stir-fry. Through a series of sterilization, sterilization and insect control treatments, reuse can ensure safety.

Precautions for the use of nutrient soil.

When using garden soil to make nutrient soil, it is best to choose no disease, and the soil layer is sparse, you can choose garden soil, organic fertilizer, pond mud, bran ash according to the ratio of 4:2:2:2 to mix and prepare, when using garden soil to make nutrient soil, it is best to add an appropriate amount of water.

Reasonable nutrient soil can promote the growth and development of plants, and the common nutrient soil of peat soil can be selected peat soil, river sand, pond mud, organic fertilizer according to 4:2:2:

1 ratio for mixed modulation, when potting with peat soil, it is best to add some peel rotten leaves on top to ensure that the soil nutrients are sufficient.

About half a year.

After opening, the nutrient soil will clump after a long time, the water will also be lost, and the nutrients in the soil will slowly disappear.

It stands to reason that it can be used all the time, but the fertilizer of the nutrient soil will fail, and the new nutrient soil can be used for about 3-6 months to add some organic fertilizer, so as to ensure that plants or flowers need nutrients.

If the old soil is to be reused, it must be disinfected and sterilized before use, you can pour carbendazim solution in the soil, or expose the soil to the sun, so that the sterilization effect can be achieved. After that, the old soil should be mixed with some compost soil or nutrient soil, the proportion of old soil is about 30 50%, and some well-rotted organic fertilizer should be added to the potting soil to help maintain the fertility of the soil.

Another way is composting, which mixes the old soil directly into the compost medium, but this takes a longer time to ensure that the soil has sufficient fertility.

It can also be directly mixed into the vegetable garden soil or flower beds, becoming a very good way, so as to achieve soil reuse, the used soil sometimes contains pathogens, such as fungi, bacteria and nematodes, etc., these pathogens can easily cause plant diseases.

In the used soil, even if fertilizer is replenished in time, it will lack the minerals needed for plant growth, which can easily lead to plant disease or death. In the old soil, there are often some weed seeds, and some pathogens or pests will be hidden, these should be cleaned up before use, and exposed to the sun when the temperature is high, you can kill germs, weed seeds, etc.

Hello! According to the description of your question, how to store nutrient soil in winter? 1.

Use the remaining nutrient soil to mix a little water, and then seal it in a plastic bag, which is not breathable. 2.Nutrient soil, also known as culture soil, is a kind of soil developed to meet the growth and development of plant and flower seedlings, and the release of nutrients conforms to the law of plant demand, which can achieve the effect of increasing yield and income, and also has the characteristics of ecological and environmental protection.

Nutrient soil cannot be used directly, although the culture soil of general potted plants does not need special disinfection.

However, it is disinfected by sun exposure.

This is because, on the one hand, flowers themselves have a certain resistance; On the other hand, the soil contains a large number of microorganisms, and their activities successively decompose many nutrients to maintain soil fertility and facilitate the growth of flowers and trees.

It can also be disinfected with high temperature or chemicals, but the microorganisms are killed, and the organic matter in the soil cannot be decomposed, which is not conducive to the absorption of flowers and trees. The culture soil used for cuttings and sowing should be strictly disinfected, because the germs are easy to invade the body of flowers and trees from the cuttings wound, causing rot and affecting survival.

The soil is only the substrate for planting plants, and the nutrients and water required are drawn through the soil.

On the one hand, the reason for changing the soil is to change a larger pot, the root system of the plant can be well soothed, and the growth can be released to a greater extent. On the other hand, in order for plants to have a better survival substrate, the soil will be barren or compacted after a long time, and even breed diseases and pests.

Nutrient soil is specially formulated to meet the growth and development of seedlings, containing a variety of mineral nutrients, loose aeration, strong water and fertilizer retention ability, and no pests and diseases. Nutrient soil is generally prepared by mixing fertile field soil with rotting manure.

The general pure nutrient soil is either too wet or too dry, which is very bad. Peat + Perlite + Vermiculite according to 3:2:

1. The ratio of mixing is better, and you can also add some garden soil or pond mud. The peat that is developed is also easier to use directly, and the general new peat soil is not as good as the old soil to drain and absorb nutrients, and it is easy to use after a period of time.

I remember someone said that the general nutrient soil is actually the soil with no nutrients, but it is relatively clean and has no insect eggs and rapeseeds. So I think it should be fertilized.

I really have money, I always prepare my own soil, but I don't have the money to buy nutritious soil.

It can be used, but the nutrition is actually not very nutritious, it is better to put some organic fertilizer in it!

If it is specially bought to grow a certain kind of flower, it can be planted directly. There are many types of nutrient soil, and different nutrient soil components are also different, such as nutrient soil for planting succulents, nutrient soil for growing vegetables, and nutrient soil for planting orchids. If you are an old flower friend, you can make reasonable adjustments according to the flowers you plant, and if you are a novice, try to buy the right soil directly for planting.

Main features of nutrient soil:

1. It can wake up the soil, increase the fertilizer effect, make the soil of the plant roots fluffy, not compacted, retain water and fertilizer, and promote the healthy growth of the roots.

2. Good air permeability, good root development, comprehensive nutrition, high yield, and light damage from diseases and insects.

I can use it directly.

Nutrient soil is generally prepared by mixing fertile field soil with rotting manure. Nutrient soil is specially formulated to meet the growth and development of seedlings, containing a variety of mineral nutrients, is loose and aerating, strong water and fertilizer retention ability, no pests and diseases of the bed soil. The requirements of nutrient soil are high organic matter content, complete nutrients, reasonable soil structure, and active beneficial microorganisms.

Applicable plants: flower plants, foliage plants, fruit and vegetable crops, succulents, wood and shrubs lawns.

Scope of use. Sowing, repotting, cuttings.

How to use: Choose a pot that is large and has drainage holes.

Fill 1 3 pots of nutrient soil.

Remove the plant from the old pot and place it in the new pot, being careful not to damage the root system.

Add nutrient soil until the pot is full, and gently press the surface of the nutrient soil after fixing the plant so that it is in close contact with the plant roots.

Water normally according to plant needs.

Absolutely, add a little sand and some dirt.
