What gives the use of superphosphate and what is this fertilizer
Once, in 1669, an alchemist, H.Brandt made the following experiment: he evaporated the urine, the resulting precipitate mixed with sand and charcoal, and then heated this mixture in a closed retort. As a result, he received a substance that had the magical property of glowing in the dark. So for the first time, phosphorus was obtained. Since then, more than three hundred years have passed, now this chemical element is widely used in various industries, as well as in agriculture. Let's talk about what can give superfosphate in the suburban area and how its varieties differ from each other. We hope this article will be very informative for all people who are engaged in growing crops in their garden.
Fertilizer with super attachment
The popularity of this substance is related to the fact thatit is, first, non-toxic, resistant to fire and explosion, and secondly, it is suitable for almost any type of soil. The use of superphosphate allows obtaining very high yields of corn, beet, potato, flax, vegetable, cereals and other crops. And experts recommend for good results to combine the use of this substance in the main feeding with the addition of a small amount in the holes or rows immediately before the sowing. Perhaps you already had a question by this time about how much fertilizer should be applied. Note that the use of superphosphate directly depends on the soil fertility level, the use of organic additives and the cultivated crop. In addition, the variety of fertilizer used should be considered. For example, for vegetable crops, the average dose is 40-60 (when available is simple) or 20-30 grams per 1 m2 (if double superphosphate is planned to be used).
