Pedee, Oregon | Years ago a company I worked for applied it on contract for/from a wood-boiler fired paper mill. We had a little different time with it as they routinely burned shredded tires for more heat, resulting in high zinc levels (as can be high in zinc without tires).
We tried to market it as a lime substitute, but learned that it was better as a soil builder and micro nutrient builder. Average application was 8-12 dry ton per acre. If I remember right it usually had 15-20% lime equivalence score.
We had some farmers that reported seing some herbicide activity reduction with ash but we had no formal testing for it. We did some research/test plots in Christmas trees, ash application resulted in doubled root mass and 1/3 larger tree by the third year. There are still farms here that use ash and really like it. I don't know of any that is allowed organic status but I suppose it could be possible with 100% wood fuelstocks. | |
