SC | In my opinion, more 28%, if not all 28% depending on your sulfur and zinc requirements. I like to use thio-sulfate and zinc regardless, but some don't. If P levels are adequate then continue to keep them that way through dry. 10-34-0 is an expensive way to put on P. You can either save the money for the cost difference or just apply more dry to build the P up further....depending on your land situation. More 28% through the planter makes side-dressing go a little faster too. | |
