Aberdeen MS | If you soil sample, then you are utilizing what the universities and labs say regardless of what their recommendations say.
That is the basis of what we have used to date. The universities and labs have told us what the crop removes (via lab tests), they tell us what reserves are in the soil (via lab tests), and they SUGGEST what to do to replace. Many growers write their own recs to give themselves the best economic return on their soils. The results of data from the U of Mn probably don't hold water for MO if used verbatim, nor do they work verbatim for Ed's soils in OH. But they do offer an insight and launching platform to answer some of the "what ifs" for those that don't see certain responses to broad spectrum applications.
It requires a higher level of micro management. Some are comfortable with that higher level, others are not. Does not make one grower better than the other one.
No different than one grower going totally 100% triple stack latest greatest hybrid offered this year, and the guy across the road taking a less "aggressive" approach to his hybrid selection.
As a seed sales person, you know that different hybrids will react differently in different fields. You work with what you have to maximize economic return, and if that means cutting back in certain areas or fields, then to stay in the game, that is what one has to do.
Many times I personally when utilizing starter have had areas that got it, and areas that didn't get any. Yield monitor showed no difference at all in yield. Comparing soil samples showed no difference in reserves. One can deplete the reserves to come under maximum economic return, but you cannot deplete a soil down to nothing. Those that stay on top of what is happening in their fields will correct when correction is needed and not before. Other that operate "cause it's what we've always done and it works" will have no clue when the time for correction comes due.
Without being on halfbaked's fields, seeing his data, or his fertility program, you are painting with a very very wide spectrum brush that MAY be very skewed in the wrong direction. | |
