Consult our 3 and 5 Star Fertilizer Guide 2020-2021
Our 3 and 5 Star fertilizer boost soil capacity to release nutrients from the soil using fertilizer bases with specific characteristics.
In addition, we have known for a long time that deficiencies in minor elements such as zinc, boron, copper and manganese limit the development and yield of crops.
The minor granular elements added at a rate of a few kilograms per ton of fertilizer are poorly distributed in the fertilizer strip and therefore inefficient. This is why our 5 Star programs have integrated the Microsyn technology which consists of coating each granule with minor elements. This ensures an even distribution on the ground of these elements.
In this guide, the results show a higher profitability with the 5 Star. The gains are not the same from one year to the next. They are more significant in more difficult spring conditions such as in 2015 and 2017 where precipitations in May were above average.
Moist soils warm less quickly, limiting the development of roots, hence the importance of providing a top quality starter. The spring of 2018 was the most favorable for root development with a warmer month of May and below average precipitation.
This combination has limited the beneficial effect of a 5 Star starter compared to a regular starter, as the roots have benefited from more favorable conditions for their development. Nonetheless, the 5 Star starter was more profitable than the regular starter.
