Boric acid mark B.

BOR of all the trace elements most strongly influences plant development and crop quality. The high content of sugars in various fruit crops, beets, watermelon, as well as the starch content in potato tubers, it happens only in the case when the plants are sufficiently well provided with boron. The need for Bor different cultures have different. Dicotyledonous plants (almost all vegetables and fruit) absorb significantly (10 times) more boron than monocots (grasses). Especially a lot of it accumulates in the flesh of apples.

Boron in the soil is in the form of salts of boric acid - borate. Relatively a lot of it contains silicate mineral tourmaline, but the bulk of boron absorbed by secondary minerals. Therefore, the change in the response of the soil environment in alkaline (lime), increasing the number of clay particles and humus contributes to the decrease in the mobility of boron.

The main form of assimilation by the plant boron - boric acid. She has some bactericidal and fungicidal effects, lowering the risk of disease. In addition, in Bor need all points of growth, young buds, flowers. Without boron primarily yellow and stop the growth of the tips of the shoots, sometimes they can palareti and die. Particularly useful boron during the formation of flowers and fruits. Boron can be made in two ways: through the root system (spraying the soil with a solution of boric acid in a concentration of not higher than 2 g per liter) or as foliar feeding (spraying aerial parts boric acid solution 2-3 times lower concentration).
