Product Technical Sheet - Foliar Nutrition Folex K An inorganic emulsion containing potassium and nitrogen. Crops A wide range of crops including cereals, potatoes, maize, and leafy salads. Use To correct nutrient deficiency. Also to promote potato bulking. Pack Sizes 10, 1000 litres Analysis w/w w/v Function of Potassium Potassium (generally referred to as potash) is a major nutrient which is required by all crops. It is second only to nitrogen in the amounts required by the crop. It is highly mobile and is quickly distributed within the plant. Low levels of potassium will seriously affect crop growth, quality and yield. Folex K is a unique formulation which includes nitrogen in addition to a high concentration of potassium. The balanced formulation will ensure optimum uptake of the nutrients in situations where it is required. Potassium Deficiency Potassium deficiency affects a wide range of arable and horticultural crops. The visual symptoms of potassium deficiency are usually seen in crops on light sandy soils or chalk soils. More common however is a reduction in plant size due to reduced potassium uptake. The visual symptoms of extreme deficiency are seen first on the older leaves. Most crops exhibit a yellowing of leaf margins which extends to the midrib as the deficiency becomes more severe. This eventually results in leaf necrosis, particularly at the margins.

The spray tank should be filled with half the required water. After shaking the container, measure the required amount of Folex K and add to the tank whilst maintaining constant agitation. Add remaining water to correct dilution and spray. Folex K Directions for Use Use Folex K when potash deficiency is diagnosed or suspected, or as part of a nutrient management programme on potatoes. Foliar uptake will be enhanced by the addition of NA131 unless already in tank mix with a pesticide. Apply 2-5 l/ha, in a minimum of 200 l/ha water. Crop Timing Rate l/ha Comments Cereals...
