I've followed you over the years. Whether Zn, P, K, Cu levels, how do you know after you have applied a 'fix' type level of a product, if it is even there? Will a soil test indicate it? Immediately? Two years later? For 'fix' level I'm talking like a 30ppm increase in P, 300ppm increase in K, 5ppm increase in Zn, etc. What do you do on your farm to confirm these types of application levels worked? Thanks.
I use a quart in the row on corn planting. What if I add a quart to side dress for carryover to next years soybeans? Will it last without leaching? That would cost about $8/A and eliminate a more expensive dry spread pass...
