Vegetable protected ground - this is a very important area of agriculture, which provides people with fresh vegetables throughout the year. The most widely used growing- cucumbers and tomatoes in a protected ground, but it are important to growing and melon, and green Solanaceae crops. Vegetables and greens - is a valuable source of vitamins, especially in winter, because they contain: cucumbers - a large number of Na, Cl, fiber, etc .; tomatoes - vitamins B1, B2, C, P, PP, provitamin A, sugar (2,1-8,8%), malic and citric acids and minerals; eggplant - 2,7-4,0% sugars, proteins 0,6-1,4% 0,1-0,4% fat, salt, P, K, Ca, Fe, carotene, B vitamins, fiber; pepper - vitamins (vitamin C, B1, B2 and E), carotene and rutin, many essential oils and coarse fiber; pumpkin - vitamins A and E, the elements (K, Ca, P, Mg, Fe, Cu, Zn); watermelon - sugars (mainly fructose), elements (Mg, K, etc.), pectin, carotene, vitamins B1, B2, vitamin C, seeds - Zn; melon - vitamins, trace elements.
In order to form a high performance culture in greenhouses fertilization should be done according to their needs and planned productivity. In addition to these macro plants require a significant amount of trace elements.
Unbalanced nitrogen nutrition and growing greenhouse crops on substrates is poor with micronutrients (molybdenum, iron, copper, manganese, boron, sulfur) increases the nitrate content in products.
