Urea

Urea has the highest nitrogen content of all readily available fertilisers supplied in the New Zealand market. Urea is made up of standardised granules allowing for easy use in varied farming systems.

Urea nitrogen is in the form of Urea (amide) form and first must be broken down by soil enzymes to become plant available (in ammonium and nitrate forms).

Why Use Urea?

When applied under the right conditions Urea will provide crops and pasture with the most cost-effective form of nitrogen.
Nitrogen moves quickly through the soil profile and plants are quick to utilise available nitrogen, therefore nitrogen is often the most limiting factor when it comes to plant and pasture growth.

When to Use

Summer, Autumn, Spring

Precautions

  • Avoid application in the heat of the day where possible
  • Apply pre-rainfall/irrigation (ideally 10ml within 10 hours) to decrease losses through volatilisation
  • Avoid application before large amounts of rainfall (40ml plus within 10 hours) to reduce leaching losses

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.
