Grid soil sampling and Management zones have been around for over two decades. Both techniques quantify spatial variability in farm fields. Key question: After two decades of capturing variability, are we doing it right? Does science agrees with our approach? Let’s find out.

For an intensive soil sampling strategy both zone sampling and grid sampling could and should be used in conjunction.  

The discussion will talk about the merits of both program and when and where they could be integrated.

We have the ability to collect soil samples and apply fertilizer at relatively fine spatial resolutions. However, current soil test recommendations were not necessarily developed with this in mind. Questions will be raised, answers are not promised.
