Description / Fosfol - Foliar Phosphate Fertiliser

Phosphate is often plentiful in the soil but an inadequate uptake by the crop can lead to a deficiency. By applying Fosfol, phosphorus is delivered to the plant in a foliar form allowing easy uptake thus ensuring that growth and yield are not otherwise compromised. Landowner’s Fosfol contains 20% Phosphate w/v, 8% Nitrogen w/v and has the following benefits:
  • Directly applied to plant resulting in quick absorption
  • No risk of leaching
  • When applied to potatoes, phosphorus can increase tuber numbers and size
