Effect of fertilizers on the nutrient balance tomatoes

The article presents the results of studies about the effect of the combined use of manure and mineral fertilizers on the nutrients balance of soil for tomato. The increase in crop yields has led to an increase in the consumption of nutrients compared to their receipt. To reduce the shortage of nutrients between the incoming and outgoing parts, as the increase in the yield it is necessary to increase the rates of fertilizer application and to develop measures that increase the coefficient of assimilation, annually. Carrying outbalance calculations makes it possible to establish an annual shortage of nutrients. The areas under tomato are growing year by year, improving its production technology, profitability rises. The yield and fruit quality of tomato were determined for the variants of the experience. It is established that for high and high-quality tomato harvest and restoration of soil fertility in this zone it is recommended to use fertilizer in the norm of manure 30 t/ha and manure 15 t/ha+N75P37,5K90 kg a.i./ha.
