The enterprise units has saved a lot of premiums over the last 20 some years so I am probably money ahead.  This land is along the MO river but has only flooded once, 1993, it has a good levy.  It can have issues with surface water if the river stays up for a long time. 

We have thought of separating some of the land and grouping it according to aph's but the ones that don't yield as well won't have as high an aph and the good ground will have an excellent aph but very seldom have a claim.  So it might average out.

I will probably keep watering, this field was pollinating during the 100+ temps and I haven't looked to see how well that went but if it is ok I will keep going. 

Thanks for all the advice
