I have written several times about why we use zone sampling to give our customers advice on nutrient management. The biggest weakness of a grid sample is that it is tied to a spot and extrapolated. Zones are tied to soil features, yields, topography and other pertinent information.
Sampling is across the whole zone. The article in No-Till Farmer Talks about the two strategies and defines them very well.
