Red River Valley, MN | Tissue test always come back "sufficient" which has got me thinking I might be "ok" by just running 10-34-0 on a few fields and eliminate the MAP application all together. My thinking there is that 90% of my MAP is probably being tied up, so really my only P that is available is the liquid starter with the planter. This farm produced 160bu/ac corn this year with a 160-50-30 analysis spread plus 5 gals of 10-34-0 with the planter. It would have done better with more than 9" of rain.
Regarding sulfur...as you can see in my soil test...the sulfur levels are "off the chart." Does it make any difference applying sulfur in this circumstance?
Agvise in Northwood, ND is the lab.
