WC Mn/Dakotas | Its all about ROI. How good whatever data your using is, how much a field varys and why, how much treatments cost, and if the grower is willing to make such a big change. Lots of possible scenarios.
I have not done veris or em yet. Many i talk to say there are definite limitations to running veris or em. Many others that work extensively in mapping, with and without veris, say usually they can create a zone map with imagery, elevation, and yield that is identical to veris for a fraction of the cost.
The big question is what are you trying to use this for? Soil sampling, vrt fertilization, lime, seeding, irrigation? These in my opinion all need a variation of massaging different types of data layers.
I soil sample from 1 map, seed by a different one. Looking into vrt in tx panhandle and that looks to require a 3rd map. If your apply high dollar treatments more expensive, detailed maps can be justified. I dont have guys making those big $ decisions that would give grid sampling as big a roi as my zone sampling. Are my zones perfect- NO, neither is grid and its more expensive, much more if done as carefully as i zone sample. Actually, the previous data ive seen from fields im now zoning had lots of errors because 1 2.5 acre grid should have 2-3 zones in it. So more sample points is more accurate, but also more expensive.
A grided zone might be the ultimate. Precision Planting smart firmer might get the o.m. and moisture. Better aerial imaging might be a benefit. em coupled with ground penetrating radar might be a game changer. Veris pH might be the biggest factor to consider if done in the right conditions. | |

Cost for Veris mapping? Does this sound right?
