this is an example of what i am dealing with outside the gates. This is a number of issues, but primarily it is linked to the calcareous soil here, the high pH irrigation water, itself abundant in carbonates and not used frequently enough to leach excahangeable cations below the root zone, the lack of humus, organic matter and over soil stability, the loss of fungal mass due to poor IPM practices to control root pathogens, themselves a consequence of poor soil management and structure, lack of N due to irrigation flaws and high soil buffering, leaching Sodium interfering with K uptake, Mg uptake slowed by applications of Ammonium N, itself a reaction to the calcareous soils from previous owners, lacking both leadership and so best practice through years of tossbag agricultural industry experts miss leading them.
I have lots to fix here, now its prune, next its add the bokashi compost, cardboard, woodchips, bokashi manures, relay the new irrigation lines, introduce new IPM practices to limit insect and competing plant matters. Continue with specified foliar treatments until i can fix the soil every 4 weeks.
target is 3500 boxes per acre in 2 years ;-)
