[QUOTE="Dave, post: 171216, member: 498"] Grandpa must have really believed in chicken manure. I would doubt that you need any K with this high of a P test result. You can probably get by with just N for the next 5 or 10 years. In some areas where they are beginning to regulate based on P levels you would be on their list. However most P losses are through soil erosion and you wont lose much soil from a pasture. By the way with that high a P level I would look closely at the K level. High K level in the soil can cause the grass to luxury consume K this can lead to low Mg level in the grass which leads to grass tetany. Dave [/QUOTE]
