There are a few plots on property in northern wi that we had some soil tests done last year. The main one I was concerned about was at a ph 6.5 amazingly. However all plots were very low in potash. So my question is that if I want to start the tilling process now with lime... can I add 0-0-60 now with the lime and plant later or should I mix that in with other fertilizer when tilling/planting date comes?
