Vegetable of protected soil – is a very significant direction of agriculture, which provides people fresh vegetables throughout the year. The growing of cucumbers and tomatoes in a protected soil became the most widely spread, but it is important to grow also melon, and green solanaceae crops. Vegetables and green - 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, it is quite caloric.
In order to form a high performance of crops in closed soil the fertilization should be done according to their needs and planned productivity. Except macro elements, these plants require a significant amount of microelements.
Unbalanced nitrogen nutrition and growing of greenhouse crops on substrates with poor compound of micronutrients (molybdenum, iron, copper, manganese, boron, sulfur) increases the nitrate content in products.
