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)
