DDCrop Compound

DDCrop Compound is suited to precision drilling applications when clean uniform granules are a priority. DDCrop compound should be used as a starter fertiliser instead of DAP when potassium is a higher requirement than phosphate.

• 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.

• 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

• 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 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.
