Question:
I have multiple new farms that have zinc levels from 178-260. Would it be a good idea to break these farms deep and lime them to 6.7-6.8 or would bringing the ph to 6.7-6.8 be sufficient? I believe the highest is in the low 300's, but the median range is 215. I appreciate your input.
Jordan:
Is this the index value or pounds of zinc per acre?
Follow Up:
Index value.
Jordan:
You should be okay. If pH is above 6.5, you should be able to handle a NCDA index of 1,000. Maybe even higher but certainly an index of 300.
Follow Up:
Do you think using a mold board plow is unnecessary as long as I get the ph 6.5 or higher?
Jordan:
I don’t think moldboard plow is needed.
