Foliar Feeding of Field-Grown Tomatoes

With proper care, including fertilization, tomatoes form a high yield. The most important elements in the period from the start of flowering and formation of the first fruit cluster to the start of ripening are phosphorus, potassium, boron, calcium and microelements. Since diseases, in particular late blight, cause great harm to tomato plants, feeding with phosphorus in the form of phosphite should be carried out as a supplement to fungicide protection of the crop.

Yield level and especially harvest quality (first of all the content of dry matter, the lion's share of which is sugars) are closely linked with mineral nutrition. To ensure high quantitative and qualitative yield indicators ECOORGANIC recommends the following foliar feeding scheme:

When growing tomatoes with drip irrigation, two feedings of plants at intervals of 7–10 days with the special fertilizer FITOSTART Jet at 20–25 litres per ha each time will be effective.
