    DIY superphosphate "tea"

    Often, novice gardeners and gardeners are faced with the difficulty of breeding superphosphate in cold water.
    But the picture changes when the water is brought to a boil. When stirring, all the useful elements of the fertilizer dissolve, turning into a form that is easily digestible for plants. A small precipitate of impurities remains.
    But it is better to use double superphosphate, which dissolves perfectly in water, and it also requires half of it for dressing.

    I buy fertilizers for the garden at the end of winter, when they are cheaper. In the list of compulsory purchases, I always have double superphosphate and potash fertilizers. Previously, superphosphate was taken without looking, and last year one of the customers in the line began to question the seller in detail about superphosphate additives. It turns out that this spring fertilizer can be enriched with nitrogen, boron or molybdenum.
    Boric superphosphate is useful for beetroot.
    Nitrogen is best for pumpkin.
    Enriched with molybdenum - for legumes.
    I tried to adhere to these recommendations - and got a great harvest. Now I always pay attention to the explanations on the package.

    Usually I used double superphosphate for fertilizing the garden, but then I had to buy a simple superphosphate. I would like to know which phosphorus fertilizer is better after all?

    • OOO "Sad"

      There are many types of phosphate fertilizers. The most widely known of them are simple and double superphosphate. Both of these fertilizers are granules, but the phosphorus content in them is different. In simple superphosphate of phosphorus about 21%, in double - more than 50%. You also need to keep in mind that double superphosphate is a slightly acidic fertilizer.

      Another phosphate fertilizer is phosphorite flour, with a phosphorus content of about 24%. It is perfect for acidic soil (when applying this fertilizer must be mixed with the soil), as well as for the enrichment of compost and for introduction into the planting pits.
      On certain soil types, for example on soils with excess acidity, phosphorus, even in large quantities, may not be available to plants. In order for plants to not feel phosphorous starvation, it is necessary to defile the soil by applying lime-containing substances.
      Recently, in addition to traditional fertilizers, gardeners have been using complex fertilizers - for example, containing mineral elements, organic substances, and even in doses suitable for a particular crop, however, any fertilizer, even the most modern, must be applied correctly.
      So, phosphorus fertilizers can safely be introduced into the planting holes during the planting of various perennial crops and even vegetable plants (making into grooves). Before planting for perennials, it is advisable to make phosphorite flour and various soluble phosphorus fertilizers that do not contain nitrogen in their composition.
      In spring and autumn, for plants that are already growing, it is better to use phosphorus no-potassium fertilizers in granules that may contain nitrogen, although fertilizers can also be applied without nitrogen.

      In the second half of the warm season, it is best to apply complex fertilizers-soluble, containing phosphorus and potassium in its composition, but devoid of nitrogen.

    in the table, which lists fertilizers for summer, there are no solutions of Mullein and bird droppings. Why? After all, they are the most popular. And more: in what form do mineral fertilizing?

    • Nikolai CHROMOV, Cand. of sciences

      From the middle of summer it is better to exclude from fertilizing nitrogen-containing fertilizers (mullein and bird droppings are just extremely rich in nitrogen), since they stimulate the formation of leaves and shoots, and in fact at this time it is more important to form ovaries and root crops. About mineral fertilizers: in the summer they can be scattered in dry form, combining with loosening and watering, but in spring all dry fertilizers should be diluted in water and watered the soil.

    Among the fertilizers for autumn digging is called potassium sulfate. And if I can not find such a sale, can I replace it with potassium chloride (it is also cheaper), is it harmful? Dmitry Volodin, Zhytomyr district

    • Summerman, gardener and gardener (anonymous)

      Your fears are not unfounded: for plants that are particularly sensitive to chlorine (tomatoes, potatoes, cucumbers), it is better not to make potassium chloride.

    Fertilizers in ... a spoon and a glass
    To measure the right amount of fertilizer, do not necessarily have a balance. It is much easier to use the usual container used in everyday life. Of course, I did not open America here, just brought the known data into one table.

      very well
