The total demand of tomatoes for macronutrients – nitrogen, phosphorus and potassium in the context of the planned yield from 40 to 100 tons per hectare, taking into account the availability of mobile forms of nutrients in the soil, is shown. The average doses of the main fertilizer application during the preparation of the soil for tomatoes, the timing and doses of fertilizing tomatoes with nitrogen fertilizers when they are applied with fertigation during sprinkling and the fertigation program for drip irrigation of tomatoes for processing are presented. |
