Why is phosphorus fertilization in the fall important?

Although most of the phosphorus, about ¾ of the dose of this macronutrient, plants consume during growth, i.e. at the beginning of vegetation, phosphorus fertilization in the autumn is equally important. Find out how supplementing this element in August will affect the development of plants in your garden.

What does the assimilability of phosphorus depend on?

Phosphorus is present in the soil mainly in the form not assimilated by plants. How do they take up this macronutrient necessary for growth? They are helped by the activity of soil microorganisms, which change the form of phosphorus from hard-to-absorb to easily absorbed by plants.

The intensity of phosphorus uptake by plants depends primarily on soil moisture, the pH of the soil and its temperature. The amount of uptake phosphorus decreases with the growth and maturation of garden plants. Phosphorus is best absorbed if the pH of the soil oscillates between 6-7.

This macronutrient in acidic soils (pH below 5) and alkaline soils (soil pH above 7) is unabsorbable by plants. Phosphorus will also not well absorbed if too much zinc and iron accumulate in the soil. Therefore, it is unfavorable to fertilize the soil with artificial fertilizers.

What is the cause of phosphorus deficiency in soil?

Reduced phosphorus content in soil is usually due to uptake of this element by plants. element by plants. However, it can be caused by leaching, such as under the influence of rain. influence of rain or absorption of this element into the soil.

Soils that are most susceptible to phosphorus deficiency:

✔ contain a lot of organic matter,

✔ have a pH below 5,

✔ are very light.

How does phosphorus affect plants?

✔ Influences the proper development of the root system of any plant. It facilitates Thus, the effective uptake of other nutrients that are necessary for growth.

✔ It is a key element in the process of energy storage and consumption -. allows plants to mature properly, and even speeds up the process.

✔ It is the basic macronutrient that shapes flowers.

✔ It participates in cell wall construction and DNA formation.

✔ This element has an important influence on the course of photosynthesis.

✔ Increases plant resistance to harsh weather conditions.

✔ Phosphorus reduces nitrogen absorption in the soil.

Why is phosphorus fertilization in the fall important?

Why fertilizing plants with phosphorus in autumn is one of the key treatments maintenance? Phosphorus strengthens your plants and protects them from freezing during winter. Perennial plants will bloom faster in the spring and be stronger because the phosphorus, accumulated in the soil, will remain in it until spring. spring.

Soil rich in phosphorus makes the plant more resilient to biotic stresses. biotic stress, is more resistant to disease and produces a more abundant yield.

Phosphorus affects the proper development of roots. If the plant is difficult access to water, such as by lack of precipitation, a properly developed developed root system, it will help it draw water and nutrients from a larger area.

What limits the uptake of phosphorus by plants?

✔ phosphorus deficiencies in the soil

✔ abnormal soil reaction (acidic – pH below 5 or alkaline – pH above 7).

✔ low amount of organic matter – lack of humus;

✔ excess or deficiency of water,

✔ too low a temperature (this factor largely limits the uptake of phosphorus),

✔ disturbed bacterial flora,

✔ soil poor in potassium and magnesium.

How does phosphorus deficiency affect plants?

Phosphorus deficiency disrupts biochemical processes in plants: for example, it stops phosphorylation or the formation of nucleic acids. This causes a lack of growth plants and abnormal metabolism. Deficiency of this macronutrient in the soil can cause plants to dwarf.

How to observe phosphorus deficiencies?

Plants that are deficient in phosphorus will have dull leaves with darker, bluish-green color, usually with a purple or violet tint.

Other symptoms of phosphorus deficiency in the soil are that plants have trouble growing (they are relatively small). Sometimes we can also notice brown spots or withered leaf edges. These are called necrotic spots, which lead to a deformation of the leaves.

After a few weeks, necrotic spots appear on the leaf stems. Leaves turn, curl heavily and die. The dead leaves are twisted and shrivel and are purple-brown in color.

Long-term phosphorus deficiency will severely weaken the root system of plants and reduce your harvest.

How to naturally replenish phosphorus in soil?

BioGarden naturally replenishes phosphorus deficiencies in soil.Microorganisms that are contained in BioGarden take part in the process of releasing phosphorus in the soil and changing its form into a bioavailable form for plants.

What's more, BioGarden is a 100% natural preparation that we can also use in the autumn. How to use it? Dilute 10 ml of the preparation in 10 l of non-chlorinated water. We can water 10 m² of soil with this amount of preparation.

Plants for which the use of BioGarden in autumn is particularly beneficial include tomatoes, peppers, rapeseed or winter wheat.

Thanks to the appropriate selection of bacteria, the preparation restores the balance of the microbiological balance of the soil, so that it retains minerals and water.
