Key Conclusions
Using Agrocote Max on leeks reduces nitrogen losses, increases marketable yield by 4%, increasing farmer income by 874 €/ha, while also increasing the quality of the harvest.
Objective
To evaluate the impact of yield and quality of using Controlled Release Fertilisers (Agrocote Max) in comparison with nitrification inhibitors based products (DMPP) for leek production.

Results
The most important parameters in defining the profitability of a leek crop, are quality classes and produce classification by sizes.
The highest price will be paid for Flandria class and size 3-4.
Agrocote Max resulted in a significant difference in both the mean piece weight and total marketable yield. By increasing the percentage of Flandria quality class combined with the highest % of class 3-4 as size quality, the product led to a positive ROI.
Overall Agrocote Max provided a better score improving quality parameters during the whole crop cycle (darker color, and a more voluminous and healthier crop).
- By using Agrocote Max, the nitrogen losses reduced significantly, increasing marketable yield by 4%
- Agrocote Max increased the percentage in Premium (Flandria) quality class and in the produce classification by sizes, leading to a positive ROI
- With Agrocote Max, an extra income of 874 €/ha was achieved vs nitrification inhibitor based products (DMPP)
