Pedee, Oregon | Wood ash can work, need to get a CaCo equivalent test done on it and see how many ton/acre to apply. In my experience, ash is better used as a potash and micronutrient source, better at that than pH adjustment.
Lime is expensive here, brought in by barge or rail. A buffer pH test is valuable to compare results of lime application neutralizing potential in your soils, with that you can evaluate the economic impact on your bank account and potential future crop performance. Picking an alfalfa variety that is tolerant of lower soil pH may be more financially viable than liming. | |
