High N is a particularly useful product for a regular nitrogen boost or where crops are under stress during early growth due to weather or root zone conditions.

High N is not intended to replace soil-applied fertiliser, but to provide additional nutrients in times of need.

Nitrogen Deficiency
Nitrogen is highly mobile within the plant and is also in constant conversion within the root zone.

Root zone nitrogen is also prone to rapid movement down into the subsoil under high irrigation and heavy rainfall, so it is necessary to monitor levels throughout the season by SAP testing.

Deficiency shows as a widespread slow down of growth which becomes chlorotic as nitrogen levels drop. If deficiency remains unchecked, the chlorotic areas will eventually become necrotic and die.


Use High N when deficiency is diagnosed or suspected, to boost yield, or as part of a nutrient management programme on a range of crops. Foliar uptake will be enhanced by the addition of NA13¹ unless applied in tank mix with a pesticide.

Apply 3-6 l/ha, in a minimum of 200 l/ha water.

The spray tank should be filled with half the required water. If applicable, add the required amount of NA13 to the water before the High N. After shaking the container, measure the required amount of High N and add to the tank whilst maintaining constant agitation. Add remaining water to correct dilution and spray.  


Do not apply in tank mix with pesticides when crop is showing deficiency symptoms, is under stress, or in adverse weather conditions.

¹ NA13 is an adjuvant designed to help with improved adhesion, deposition and penetration of the spray solution on the leaf surface. NA13 should be added at 0.1% of the spray volume, e.g. 100 ml in 100 litres of water. Maintain agitation and apply immediately after mixing.
