Sharpen rates and plant-back

The label answers both with a table, not a single number. Here is what drives each answer.

Application rate

Your rate depends on your crop and your soil texture.

Get the rate for your field: build a program and FieldMarshal cites the exact per-acre rate for your crop to the label line.

Plant-back and rotation

Your interval depends on your application rate, the rotational crop, and your state, region, and rainfall — some intervals differ in AZ, CA, CO, IA, ID, IL, KS, MI, MN, MT, ND, NE, NM, NV, NY, OK, OR, SD, TX, UT, WA, WI, and WY.
