NAAS gives advice on feeding crops

According to the press service of the Ministry of Agriculture, the dose of nitrogen fertilizers in spring feeding is determined by many factors (predecessor, state of crops, level of basic fertilizer) and mineral nitrogen reserves in the soil. That is why "first of all, it is necessary to feed thinned and underdeveloped crops, where the approximate dose of nitrogen fertilizers in the active substance during the recovery of spring vegetation should be 60-70 kg/ha, on crops in satisfactory condition - 50-60 kg/ha, in good — 20-30 kg/ha. On well-rooted winter crops (mainly winter rye), provided they have a good wintering, the first feeding of plants in the early spring period can be postponed to a period 8-10 days after the restoration of spring vegetation."

It should be noted that these are generally accepted, proven by science and many years of production experience doses of nitrogen fertilizers for fertilizing crops of winter grain crops, depending on their condition after overwintering.

"In the conditions of this year, producers, to a greater extent, have to make their own decisions regarding the fertilization of winter crops in each field, guided primarily by the availability of a certain type of fertilizers, their quantity and the need for distribution between winter and spring crops, the state of crops and with a view to minimizing passing machinery across the field in order to save fuel, as this year's situation on the fertilizer market requires optimizing the plant fertilization system and increasing its efficiency," the report says.

At the same time, it is also necessary to remember the unproductive losses of nitrogen for various types of fertilizers: urea - 4-45%, ammonium sulfate - 24-27%, ammonium nitrate - 18-20%, calcium nitrate - 10-12%, carbamide ammonia mixture- 3-5%.
