Tomatoes, with proper care, including fertilizers, form a high yield. The most important elements in the period from the beginning of flowering and the formation of the first tassel of the fruit till the beginning of ripening are phosphorus, potassium, boron, calcium and trace elements. As diseases, in particular late blight, cause great damage to tomato plants, it is necessary to fertilize with phosphorus in the form of phosphite as a supplement to the fungicidal protection of the crop.
Yield levels and, especially, crop quality (primarily dry matter content, the big share of which are sugars) are closely related to mineral nutrition. To ensure high quantitative and qualitative indicators of the harvest, the company "ECOORGANIC" recommends the following scheme of foliar nutrition:
| Beginning of flowering | Fruits - the first tassel | Intensive fruit growth | Milk ripeness | Beginning of fruits browning |
| GROS Quitselium 1,5 l/ha | ECOLINE Phosphite (К)
1,5 л/га |
ECOLINE Magnesium (Chelates)
1,5 л/га + ECOLINE Boron (Оpti) 1,5 л/га |
ECOLINE Phosphite
(К-Amino) 1,0 л/га |
ECOLINE Calcium-Boron (Chelates)
2,0 л/га |
When tomatoes are grown with drip irrigation, it will be effective to fertilize the plants twice, with an interval of 7 - 10 days, with a special fertilizer FITOSTART Jet at the rate of 20 - 25 liters per 1 ha at a time.
