Why Use DDCrop?

DDCrop is well suited to be used as a starter fertiliser on higher value crops that have a requirement for nitrogen, phosphorus, potassium and sulphur. As a compound fertiliser DDCrop is suitable for use through precision planters. DDCrop contains nutrients in the following forms:

  • Fast acting and plant available nitrate nitrogen and ammonium nitrogen
  • Plant available water-soluble phosphate
  • Water-soluble readily available potassium chloride
  • Plant available sulphate
  • Also contains calcium and plant available magnesium

When to Use

Autumn, Spring


  • Avoid applications on chloride sensitive crops

Nitrogen's Role in Plants

  • Nitrogen is always the nutrient in highest demand by plants, due to the greater content of nitrogen present on a dry weight basis in comparison to any other nutrient.
  • Nitrogen is a primary component of amino acids which are the building blocks of proteins. Thus, by adding nitrogen to soil the protein content in plants is increased.
  • Nitrogen is part of the chlorophyll molecule, and a part of numerous enzymes and coenzymes. Chlorophyll is responsible for photosynthesis, where sunlight is absorbed and stored in the plant as sugars and proteins.
  • Therefore, nitrogen is an integral part of photosynthesis.
  • Signs of nitrogen deficiency – reduced plant growth, yellowing of the leaf, early crop maturing.

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

Potassium’s Role in Plants

  • The main role played by potassium in plants is the balancing of negative charge from anions such as nitrate and sulphate.
  • Potassium is required for protein and starch synthesis and is involved in activating enzyme systems within the plant.
  • Potassium enhances plant quality through shape, size, vigour, and strength.
  • Grasses and clover compete for potassium, therefore low potassium pasture has no clover present and high potassium pasture has a strong presence of both grass and clover.

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.

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

Magnesium’s Role in Plants

  • Critical for both plant and animal growth, with deficiencies noticed in the animal before the plant
  • Assists in plant defence processes against abiotic stresses
  • Magnesium is the central core of the chlorophyll molecule – therefore its presence is vital for photosynthesis
  • Low levels of plant intake can lead to hypomagnesaemia in livestock, especially during the winter/early spring months
  • Magnesium is very mobile in the plant and aids in numerous plant processes such as enzyme activation and phosphate metabolism, as it acts as a phosphorus carrier
  • Magnesium and calcium working in synergy to promote stable soil structure
