Copy link Agromaster® Trial in Germany with Potato
6.6
IASP, Berge
6.6
Key Conclusions
A single application of Agromaster®, compared to the grower’s practice consisting of 2 applications of CAN, yielded 25% more tubers larger than 55mm, and produced a 6.6% higher marketable yield (tubers larger 35mm). Agromaster®’s controlled release of nitrogen increased the nitrogen use efficiency, ultimately producing a positive return on investment (ROI) of an extra 146 €/ha.
Objective
To compare the efficiency of a single application of Agromaster®, a Controlled Release Fertiliser from ICL, when compared to the grower’s usual practice of 2 applications of conventional N fertiliser (as CAN).
Trial Details
Treatments
This trial evaluated 3 different fertiliser treatments for Ware Potatoes (var. Augusta). All 3 treatments received the same level of P, K, Ca, Mg and S. The control received no additional nitrogen, while the standard grower’s practice and Agromaster® treatments received nitrogen fertiliser as shown in the table below. The trial was set up using a randomised block design with 4 repetitions.
| Treatment | Product | Total-N mineral, kg/ha | Timing |
|---|---|---|---|
| Grower Practice | CAN 27-0-0 | 108 | Before planting |
| CAN 27-0-0 | 72 | Mid-June | |
| Agromaster®* | Agromaster®* 35-0-0, 2-3M, 60% coated N | 180 | Before planting |
All treatments received the same level of P, K, Ca, Mg and S.

Results
The trial showed that Agromaster® increased the marketable yield of potatoes by 6.6%, with a 25% increase in the yield of larger potatoes, those over 55 mm, compared to the grower’s practice.
Total yield distribution by size (mt/ha) for potato grown with Agromaster®, compared to the control and the grower’s practice treatments.
Agromaster® increased nitrogen use efficiency (NUE) by 24%, thanks to the controlled release of nitrogen.
