Every successful maintained sport pitch starts with a good soil and turf management plan. Mivena is happy to help you make the right choices. The winter period is a tough time for the turf. Wet conditions cause extra play damage and there is no recovery growth due to the low soil temperature. Spring (March) application is the perfect time to stimulate the turf with its recovery growth.
Control vertical growth
Control vertical growth is primarily to minimize readily available nitrate. The optimal fertilizer for this period must have a controlled availability of elements even at low soil temperature. Mivena’s coated products Granucote®CRF, Greenstar®CRF and Granupermanent Universal®CRF perfectly matches this desired availability.
Controlled availability in the first place to avoid obesity grass. Second, to prevent leaching. The major advantage of mineral coated fertilizers compared to the organic variants is the availability of phosphates, potassium-sulphates, and nitrogen early spring.
A balanced fertilization strategy is essential to keep the turf in vital conditions. High nitrate levels in early spring increase the disease pressure turfgrass and should be avoided. In early spring, plant crop growth is still minimal, which easily results in an imbalance in the grass plant.

Last year Mivena tested different fertilizer strategies on Bermuda variety at Neval Trial Centre Spain.
Results Neval Trials 2020-2021
Conclusions regarding the parameters of growth:
Quicker filling (closing) the gaps with Granucote CRF 23+5+12+2MgO+Fe+Mn 8/9M
Horiontal growth
Significant differences were observed for Granucote CRF 23+5+12+2MgO+Fe+Mn 8/9M, in comparison with Fertilent 20+7+9+2MgO. Granucote CRF had better coverage and got 3 weeks before Fertilent the 100% coverage of the area.
Vertical growth
According to the fresh and dry weight Granucote CRF had less vertical growth during the study, being 700 grams of difference between the fresh weight of Granucote CRF in comparison with Fertilent.
Root length
Granucote CRF had longer roots than Fertilent during all the study and was increasing progressively having 7 cm more in the last assessment.
Qualitative parameters:
Color and Brightness
The turf treated with Granucote CRF had darker colour during the study, expressed as a by the colorimeter in comparison to Fertilent, while the parameter b (yellowness) was smaller in Granucote CRF than in Fertilent. Brigthness was increased significant in Granucote CRF from June.
Percolate:
The content of Ammonium and Nitrates during the study did not exceed de minimum content in both tested thesis. Total water percolated per bin was similar with no statistical differences between 55 to 60 L of water accumulated per month.
