Hi! Peter, I have not yet used it enough or for long enough to check this out. I have talked about it to a range of people from Ag Consultants to Pest Plant Control people and all believe that it should be of little if any impact. It is considered that it will not even have any measurable effect on the pH. I think the only effect will be the reduction of weeds, there for reducing habitat for those that live on their living roots and the provision of dead weeds, thus the habitat for those that live on the dead material. So there will be some change, but not of a significant impact.
Are you spot spraying particular targets or blanket spraying? Are you using green manure's? They are a big start on weed control, as Nature does not like voids and will seek to fill them. I am very impressed with my cousin with his clover grown under apple trees. He cuts it regularly and needs no manure, only a little compost which be makes with the BD Compost Preps. After some years he now has virtually no weeds. I have only visited him in winter or spring, so I do not know if he grows barley or another grain in summer. (We are in a Mediterranean climate.) By contrast, the next farm to me has a vineyard which has the beejeese sprayed out of it and each year get at least one new weed. Some are the only examples in the district. Have you read the Patient for the Vinegar/ Lemon juice spray? I assume you would dilute the apple cider vinegar a bit. Gil
