Recommendations for foliar feeding of potatoes

Depending on planting dates and the region, potatoes are between the stem development stage and the start of tuber formation. Weather conditions over large areas were extreme for the crop. Because of night frosts, part of the area suffered damage to the above-ground part of the plants. In this period attention should be focused on maintaining the health of the plant roots and the photosynthetic apparatus. In the southern regions with hot, dry conditions, in order to reduce the negative effect of excessively high temperatures and moisture deficit, carry out foliar feeding of potato plants with anti-stress products.

There are certain differences in feeding schemes related to soil characteristics.

Drained peat soils

  1. Active growth – ECOLINE Magnesium (Chelates) 1.5 l/ha; when signs of stress appear we recommend anti-stress products ECOLINE Phosphite (K-Amino) 1.0–1.5 l/ha or POLYACTIVE Boost 1.0 l/ha
  2. Start of tuber formation – ECOLINE Copper (Chelate) 1.0 l/ha + ECOLINE Phosphite (K) 1.5 l/ha

  3. Ripening – ECOLINE Calcium-Boron (Chelate) 2.0 l/ha

    Mineral soils

    1. Active growth – ECOLINE Magnesium (Chelates) 1.5 l/ha + ECOLINE Phosphite (K-Zn) 1.5 l/ha
    2. Start of tuber formation – ECOLINE Phosphite (K) 1.5 l/ha + GROS Amino-Zn 1.0 l/ha
    3. Ripening – ECOLINE Calcium-Boron (Chelate) 2.0 l/ha
