Urea PluS

$820.00/t - Ex-Store

Urea PluS is a blend of Urea, Ammonium Nitrogen and Sulphate. Urea PluS is best suited to warmer soil temps and on lighter and/or irrigated soils where S can be a limiting factor to N response.

Why Use Urea PluS?

At Dickie Direct our core range of phosphate products do not contain Sulphate. For soils requiring sulphur we typically blend in elemental sulphur in the form of Sulphur 90S with these phosphate applications. With nitrogen applications we then blend in fast acting Sulphate at varying rates to ensure available sulphate is not a limiting factor to the nitrogen response. Sulphate requirements will depend on soil temperature, soil type, rainfall/irrigation and existing soil sulphur levels.

We recommend using Urea Plus during warmer soil temps (over 12 degrees) and on lighter soils and/or irrigated soils. In cooler soil temps we recommend using Ammonium Sulphate or Ammo 30.

When to Use

Summer, Autumn, Spring

Precautions

  • Avoid application before large amounts of rainfall (40ml plus within 10 hours) to reduce any leaching.

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.

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.
