Explanation sports fields
Each crop requires nutrients. The essential nutrients that a crop needs most are nitrogen (N), sulphur (S), phosphate (P), potassium (K), calcium (Ca), and magnesium (Mg). The other essential nutrients are the micro nutrients iron (Fe), zinc (Zn), manganese (Mn), copper (Cu), boron (B), molybdenum (Mo) and chloride (Cl). A crop requires relatively low concentrations of these micro nutrients, however a deficit can cause loss of yield and/or quality in every crop.
A number of other nutrients (sodium, silicon, cobalt, selenium) can also be important to - amongst other factors - the yield, quality, resilience, sturdiness, fertility, palatability and (animal) health.
Elements can also compete with each other. For example, if the Mg status is “good” but the K status is “high”, then an Mg deficiency can still occur. Therefore, the recommended dosages take these interactions into consideration.
In the first year after construction, the condition of the soil changes significantly. To fertilize correctly the year after installation, a new soil sample is recommended
Analyzing the grass clippings is a good tool to assess whether the N and P contents in the grass are sufficient and therefore whether the fertilization is in order. You can request a Crop Check to check this.
When constructing a new sports field, we recommend to apply the doses of N, P and K through the top 10 cm.
