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).

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.
