Does anyone know how much S15 I can safely seed place with yellow peas? 3” spoons, 10” spacing. I was hoping to seed place 100lbs S15 per acre.

3" spread on 10" spacing is 30% SBU, probably as much product as you fan can move...100lbs no problem

Ok. I know SK recommends 15lbs actual phos seed placed with 11% SBU. I wasn’t sure if this translates into going that high, and if S15 is as safe as MAP

S15 should be safer than MAP. But how much safer?

I guess Jake676's logic is that if 15# is safe on 11% SBU, then the 3" spread is 33% SBU, so should be safe up to 45# actual P.

Wouldn't hurt to ask your local sales agronomist about what MicroEssentials considers safe with their product.
