They are produced in the form of powders, granules, tablets, include the mixed fertilizer, make a foliar application, and is used for pre-treatment of seeds.Micronutrient fertilizers contain micronutrients need
plants which increases with increased doses of organic and mineral fertilizers.Thus, the introduction of large amounts of phosphorus fertilizers increases the need for zinc, potash - in boron, nitrogen - in copper and manganese, lime and soil - in boron and manganese fertilizers.To make up for them in the soil using different kinds of micronutrients. Boric include boron fertilizer superphosphate (20% P and 0.2% boron), bormagnievoe fertilizer (2,25 % boron and 14% of magnesium oxide) and boric acid (17,1-17,3% boron).Boric make superphosphate in the spring presowing plow
In the absence of micronutrients for the treatment of seeds can use wood ash, which contains more than 30 trace elements.In 1 liter of warm water dissolve 2 tbsp.l.wood ash and infused for days, stirring occasionally.Then filter the solution, and it was immersed in a gauze bag seeds.Seeds of onion and carrot stand 6, and the remaining vegetables -Zch ,.
