Precision Nutrient & pH mapping Continued.

Once the field / block has been sampled, the soil is sent to an independent laboratory to be analysed for phosphorus, potassium, magnesium and pH. Additional elements can be analysed should they be required. The analysis is then sent to SOYL whereby sample point and contour maps showing the variation in nutrient levels across the field are produced. These maps are easy to understand and give an immediate picture to the soil’s fertility, and how it may vary across the field. These maps can be used for three to four years before the same area is re-sampled. In addition to producing these maps SOYL will also make fertiliser recommendations and provide application maps where needed.

When the time comes to re-sample the old sampling plan is re-loaded into the mapping software such that soil samples are taken from exactly the same location in the field.
