Phosphorus - is one of the main nutrients, without which it is impossible to imagine the normal growth of plants. It is on a par with potassium and nitrogen, responsible for the flow of all metabolic processes and viability of crops. If this trace element in the soil is not enough, the vegetation may completely die. That is why it is necessary to identify the problem in time and solve it with the help of phosphate fertilizers before the onset of the worst - crop loss.
The value of phosphorus for plants
A sufficient amount of phosphorus in the soil provides normal height cultures and their resistance to adverse weather conditions, including lowering the temperature.
If this microelement is not enough, all the vegetation may die due to the cessation of the functioning of the reproductive system responsible for reproduction. Appearance of seeds will be broken, and grain crops will become at all similar to a usual grass.Sign of phosphorus deficiency in corn sprouts
What are the signs of element deficiency?
In order to save the plant in time from any disease or fungus that attacks after the depletion of crops, it is important to know about the signs of a lack of a useful trace element. In this case, it will be about phosphorus.
The lack of phosphorus affects plants as follows:
- the color of the foliage first becomes dark green and then acquires deep purple color;
- leaflets can change in shape and even fall prematurely;
- on the bottom of the foliage appear dark specks;
- the culture can lose in height and becomes like a miniature bush;
- is observed poor root development. Sometimes the stem directly falls from the ground.
The use of phosphate fertilizers and how much can be applied
There are a huge number of mineral nutrient complexes, which have in its composition of phosphorus, but differ in names.
They can differ in concentration This trace element and the presence of impurities. Therefore, the need for fertilizer and their number will be different. This is what will be discussed further.
Superphosphate incorporates not only phosphorus, but also a small amount of magnesium and sulfur. This raw material is best used. in diluted formthen the digestibility of substances will be more effective.
This feed can be used for a huge number of crops. Moreover, there are no limitations on the composition of the soil either, phosphorus-containing complexes can be used in any case.
Superphosphate can be used not only in pure form, but also together with other fertilizers. It will significantly increase the resistance of vegetation to lower temperatures, improve immunity and ensure a high yield of all crops. And cereals, and vegetables, and fruit.
This tuk is diluted in water with the calculation 100 g per bucket.
Ammonium Phosphate (Diammophos)
This agrochemical allows to increase the basicity and significantly reduce the acid level of the soil. As phosphorus complexes themselves, diamophos can be used simultaneously with organic, for example, with bird droppings or manure. But it is important to dilute everything with water and leave some time for the composition to infuse.
Most often ammonium hydrogen phosphate is used in the spring in the process of planting crops by introducing a small amount (about 20 g) to each well.Diammofoska
This substance is used to neutralize the excess of phosphoric acid. Nitrogen will appear during the reaction, but its concentration will be substantially less than the phosphorus itself. Although both trace elements will saturate the soil in sufficient volume, as they are well absorbed.
But the concentration of ammophos will be slightly different:
- for fruit trees and bushes need about 30 g agrotuka for each square meter of land;
- for crops - 20 g;
- ornamental plants and lawn - 15 g.
Most often, phosphate rock is used to fertilize the soil in autumn. It is perfect for black soil, gray forest, marsh and podzolic soil.
This fertilizer contains in its composition about 30% of phosphorus and due to its properties, it is recommended to use simultaneously with manure to create compost.Phosphoric Flour
Bone meal is a prime example of organic fertilizer that contains phosphorus in large quantities. For those gardeners who do not dare to use tuki because of their chemical method of production, flour is an excellent opportunity to fertilize the soil with organic matter.
Bonemeal will allow to cook fine compost without the use of chemistry.
This fertilizer is presented in powder form with a concentration of phosphorus in 30 %. It is recommended to be used for any soil and all cultivated plants, both as an additional feed and for the nutrition of the entire land plot.
In its effectiveness, precipitate is not inferior even to superphosphate. Moreover, he able to reduce the level of acidity soil, having a positive effect on particularly acidic areas.
The level of phosphorus in thermophosphate fluctuates around 15-30 % It all depends on the type of fertilizer.Defluorinated phosphate
There are open-hearth slag, defluorinated phosphate and tomasshlak. Moreover, the second option is considered the most concentrated and shows excellent results on black soil.
The need for phosphate-potash fertilizers
Phosphorus-potassium complexes are widespread in view of their universality. They can be made in the fall and spring, in any period of vegetation vegetation development. With the only difference that the amount will vary.
The most popular fertilizers from this series are considered nitrophoska and nitroammofoska. It is also worth considering the already finished store composition of the phosphorus-potash direction as Autumn, they can be replaced by the previous two. It includes potassium, phosphate, boron, calcium and magnesium. And potassium most of all, almost 20%.
The most popular phosphate-potassium fertilizers are:
These power complexes are recommended to use. in the spring. And for every square meter of land need about 50 g composition. Phosphorus potash fertilizers can be used to feed not only cultivated plants, but also fruit trees.
Since the absence of at least one substance can cause the complete depletion of plants and their subsequent death, it is important to monitor the crops. The most important trace elements are phosphorus and potassium. That is why the use of these tukov deserves special attention. We hope this article will allow you to grow a good harvest.
