Why Use DDMax 75?

DDMax 75 is made up of 25% fast acting (water-soluble) phosphate and 75% slower releasing (citric soluble) phosphate.  Get an instant production lift from the water soluble phosphate while getting the medium term production lift, an overall improved phosphate utilisation and biological benefits from the slow releasing Citric Soluble P. Talk to your DD Area Manager to find out which phosphate product is best suited to your farms soil characteristics, climate and production requirements.

Key Benefits of DDMax 75:

  • Fully granulated for ease and accuracy of spreading.
  • Save on freight and application costs as a result of the higher P content in comparison to other conventional phosphate products.
  • Improves phosphate utilisation and extends the phosphate response, increasing plant production.
  • Reduce requirements for lime due to the Citric Soluble P component which has a liming effect.

Precautions

  • No precautions

Phosphorus’s Role in Plants

  • The most important role of phosphorus is the storage and transfer of energy that is generated through photosynthesis along with the metabolism of carbohydrates.
  • Phosphorus is an essential compound of Adenosine Triphosphate (ADP), the energising component driving plant development.
  • Phosphorus deficiency has a huge impact on plant growth and reproduction, reducing the plant processes noted below.
  • Processes aided by phosphorus:
    • Large root growth
    • Early formation of plant shoots
    • Improved stalk and stem strength in crops
    • Improved fruit, vegetable, and grain quality
    • Seed formation
    • Resistance to moisture and colder temperatures

Calcium's Role in Plants

  • Calcium is vital for both plant and animal growth
  • An essential part of the plant cell wall and membranes, aiding in plant structure and stability
  • Earthworm activity is increased by the presence of calcium in the soil profile, therefore natural soil aeration is also increased
  • Boosts soil microorganism activity, improving soil structure
  • Calcium deficiency affects fruit crop quality and growth, and limits biological activity
  • Calcium and magnesium work in synergy to promote stable soil structure
  • Involved in the signalling of the availability of other nutrients (e.g. potassium), through its secondary messenger characteristics
  • Assists in protecting the plant from biotic stresses

Sulphur's Role in Plants

  • Sulphur is essential in forming plant protein as it is present in cysteine and methionine, two vital amino acids involved in protein synthesis.
  • Key component of coenzymes and vitamins, involved in energy transfer and lipid synthesis.
  • Some sulphur compounds are responsible for the taste and smell of plants, like onions.
  • Sulphur amino acids are at high levels in animal fibres, therefore sufficient sulphur is required for good wool production.
  • Promotes nodule formation in legumes
  • Signs of sulphur deficiency – light green to yellowish coloured young leaves, reduced plant growth rates, plants that are short, small and slender.
