Sometimes even well-groomed country plants may lose their shape: they wither and the leaves become blue-violet. In this case, the use of fertilizer superphosphate.
Phosphorus is essential for normal life and plant development. The natural saturation of the soil with this useful substance is only 1%, and the compounds available with it are even less.
Phosphorus is involved in the energy processes of metabolism, providing nutrition to plant cells, as well as in photosynthesis. Due to this, the yield increases, and the plants acquire strength for accelerated growth.
Superphosphate fertilizer is produced on the basis of phosphorus-nitrogen compounds, in combination with microelements and minerals. This composition is saturated with many natural substances necessary for good growth and development of the fruit.
Universal fertilizer superphosphate increases the amount of crop. The complex of microelements accelerates the process of flowering and the general development of the root system and the shoot, and also provides healing and protection against the onset of various diseases.
A complex phosphorus-nitrogen compound has two main types:
- Simple superphosphate. The concentration of phosphorus in fertilizer is concentrated at the level of 25%, nitrogen - up to 8%, sulfur - up to 10% and calcium sulphate( gypsum) at the level of 40%.Simple superphosphate is available in two forms: powder and granules.
- Double Superphosphate. It, respectively, contains twice as much absorbable phosphorus( 45-55%).The nitrogen capacity is 17%, and sulfur - 6%.Double superphosphate is produced, mainly in granules, which easily dissolve in plain water.
The presence of different forms of this fertilizer allows you to apply it to specific types of plants, different types of soil and at different stages of maturation.
How to apply simple
superphosphate To achieve a high result, it is necessary to know the principles of interaction and the necessary proportions for specific plants or garden crops. How superphosphate fertilizer is applied is indicated on the packaging or in the enclosed instructions.
A simple and dual composition of universal, complex phosphorus-nitrogen fertilizer can be used for planting seedlings or seeds in any soil. Restrictions for garden and garden plants and tree seedlings also do not exist.
However, using this fertilizer, you need to take into account a small nuance - superphosphate acts weakly in acidic soils.
In order for the fertilizer not to lose its nutritional properties, it is necessary to deoxidize the soil with wood ash or lime mixture( 500 ml of lime or 0.2 kg of ash should be counted on 1m2 of soil).
The complete deoxidation process takes a long time. After one month, superphosphate can be applied to the soil. Only after this period, not earlier. The most effective way to make superphosphate simple is to directly pour it into rows or holes dug for planting or seedlings. Summer residents recommend planting seedlings immediately after fertilizing.
Remember that when working with superphosphate, it is strictly forbidden to create mixtures of ammonium nitrate, chalk, lime, urea.
Superphosphate is an independent universal fertilizer, which is obtained from natural minerals( mineralization of animal skeletons and slag processing of iron ores).Its effective use is possible only in accordance with the recommendations of specialists.
. Instructions for using superphosphate.
. Double superphosphate fertilizer is applied to the soil in early spring before planting, or until the autumn, after harvesting. Phosphorus should have time to master the soil. In the interval between the main fertilizer inputs it is also recommended to provide for watering the plants about two times.
Superphosphate fertilizer, instructions for use:
- Uniform introduction of double superphosphate is best done with a grain planter, since it has the form of granules;
- The main application of double superphosphate should be carried out before planting garden crops. Usually this is done under the plow. From the initial application, the granular fertilizer is not washed off by irrigation or rainwater and does not fall below the seed layer;
- The application of methods for manual dispersion of granules is less effective, since this fertilizer should be closer to the root system of crops;
- Many gardeners apply double superphosphate compounds in combination with nitrogen-potash and potash fertilizers, which are applied in spring and, respectively, in autumn.
For seedlings of vegetables and greens, they are applied to the soil from 30 g to 40 g per square meter of double superphosphate. To feed garden fruit tree in autumn, up to 600 g of double superphosphate per 1 m2 must be added to the soil. For seedlings and plants in greenhouses and greenhouses used 100 g / 1m2.4 grams of double superphosphate must be added to the ditch with potatoes. In the case of depleted soil, the amount of fertilizer must be increased by 30%.
Young seedlings and saplings of trees and bushes especially need nourishment and fertilizer, since there is no other way to get vital substances. Today's market offers a diverse assortment of nourishing substances, the first place among which is superphosphate.
