The composition of manure varies enormously from farm to farm. If you start from average levels, the nutrient supply can be misjudged. It is very likely that this will have a negative impact on the yields.
It is therefore essential to know exactly what you are fertilising. In addition to nitrogen (N), phosphate (P) and potassium (K), organic matter is also important for soil fertility, for example. The composition of manure can vary not only per farm but also per storage facility. Causes of these differences include:
> Differences in rations
> The amount of rinse water
> The mineral composition of feeds
> The composition of the livestock
The need for nutrients and organic matter differs per field. Sophisticated fertilisation based on the Manure Check from Eurofins Agro helps you to increase yields and is more efficient for the mineral cycle.
Unexpected problems in the crop are sometimes caused by the purity of fertilisers (excessive sodium or heavy metals).
Fertiliser producers have introduced a range of new fertilisers in recent years, such as low-sodium fertilisers and various organic products. There are also a number of new producers in the market. Before you switch to a new fertiliser or another supplier, consider having the purity and composition of the new fertiliser analysed; impurities in fertilisers can cause all kinds of problems in the crop.
