TwinN is used on a wide variety of fruit trees, forestry trees and vine crops and has enabled the replacement of either all, or a very significant proportion of, the nitrogen fertiliser requirements in these crops. Please refer to TwinN Mechanism of Action for information on how TwinN acts to increase yields and efficiency of nutrient uptake.

TwinN will be able to produce best results if producers apply normal levels of non-nitrogen nutrients and follow best practice in looking after the general health of the soil. Reduced application of nitrogen fertilisers and annual application of mulches to increase soil carbon content are first steps to good soil health.

If information on your crop is not on the website please contact your nearest distributor.

PLEASE NOTE: A recommended starting point is to apply 50% of the normal rate of N fertiliser, plus TwinN, applied once or twice. Apply the N at the same stages of the crop cycle as usual. Many producers also test, in addition, a greater reduction down to 25% of normal N. Depending on soil fertility and crop needs most systems will produce long-term sustainable high yields at between 25 – 50% of normal N inputs. Start at 50% and work downwards.
