A snippet to give you an understanding of how farming really is now.
In the field next to my house the muck spreaders are at work, but not over the whole field. The combine which self steered its way across the rape earlier this week recorded the yield variations onto a gps map which is fed into the office computer. The manure management plan then indicates which areas of the field will benefit from the muck the most and will also provide information for the gps guided fertiliser applicator throughout the season to vary the fertiliser rates across the field.
It's not all muck and mystery anymore.
