Copy link The Role of Phosphorus in Crops
Phosphorus (P) is an essential nutrient for plant growth and development, playing a critical role in various metabolic processes, including photosynthesis, energy transfer, and DNA synthesis.
Phosphorus is a component of several key plant structural compounds and is a catalyst in numerous vital biochemical reactions in plants, especially in capturing and converting the sun’s energy into useful plant compounds.
Phosphorus and DNA
Phosphorus is a vital component of DNA, the genetic code of all living things. It is also a component of RNA, the compound that reads the DNA genetic code to build proteins and other compounds essential to create plants’ structure, seed production, and genetic transfer.
Storing Energy
Adenosine triphosphate (ATP) is the ‘energy unit’ of all living things, including plants. In plants, ATP is formed during photosynthesis, with phosphorus in its structure, and participates in processes from the beginning of seedling growth through to seed formation and maturity.
Phosphorus is essential for the general health and vigor of all plants. Some specific growth factors that are associated with adding phosphorus to the crop are:
- stimulated root development,
- increased strength of stalks and stems,
- improved flower formation and seed production,
- more uniform and earlier crop maturity,
- increased nitrogen-fixing capacity in legumes,
- improvements in crop quality, and
- increased resistance to plant diseases.
Symptoms of Phosphorus Deficiency
A crop deficient in phosphorus will show slow growth, appear stunted, and be weak. Older leaves will have a dark green color and purple pigmentation. Since phosphorus is mobile in the plant, the bottom leaves are always affected first and show the earliest signs of deficiency.

Give your crops the power of phosphate
ICL PhosphatepluS is a high quality granular fertiliser combining the benefits of triplesuperphosphate (GTSP) and Polysulphate into a single granule. PhosphatepluS supplies your crop with five essential nutrients in every granule, helping to increase the efficiency of your phosphate application and boost crop establishment and root growth. PhosphatepluS is a highly effective starter fertiliser that is suitable to be used in direct drilling or can spread up to 36 metres. Trials show that applying some potash, sulphur calcium and magnesium together with phosphate at planting, increases nutrient uptake and establishment.
