• 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 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.
