AF PHOSPHORUS is a highly efficient liquid foliar product designed to provide the impetus for growth and rooting when the soil is unable to or requires recovery. Produced using a unique process of production, via the Flex Fertiliser System ApS, AF PHOSPHORUS contains a true amide complex that increases the uptake and efficiency of trace elements to the crop whilst aiding crops that are under pressure with poor compacted or waterlogged situations that could lead to difficult establishment and/or restricted rooting.

The function of Phosphorus in plants is very important. It helps a plant convert other nutrients into useable building blocks with which to grow.

Phosphorus is vital for plant development, starting at a seedling and continuing all the way to maturity.  Besides playing a role in the quality and formation of seeds, this nutrient helps ensure uniform heading, faster maturity and strengthens the plant to help survive the winter.

Phosphorus is extremely important for plant growth and maturity. Without it, a plant simply cannot be healthy. Phosphorus plays a role in photosynthesis, respiration, energy storage and transfer, cell division, cell enlargement and several other processes in plants.


Phosphorus deficiency symptoms differ in various crops and can display no obvious symptoms, however if they are visible, plants will be stunted in growth with reduced vigour, with weak root systems or a bright green/purplish tint generally on older leaves first.

By the time a visual deficiency is recognised, it may be too late to correct in annual crops. Phosphorus deficiencies late in the growing season affect both seed development and normal crop maturity. The percentage of the total amount of each nutrient taken up is higher for Phosphorus late in the growing season than for either Nitrogen of Potassium.

If in doubt, take a tissue analysis.
