To make BD 500 Horn Manure, fill a cow horn with manure and bury it over winter; the finished preparation is stirred and sprayed on moist soil late in the day. For BD 501 Horn Silica, fill a separate horn with finely ground quartz and bury it over summer; the finished preparation is stirred and sprayed as a fine mist on foliage in the morning. Keep horns reserved for BD 500 separate from those for BD 501.

One cow horn can produce enough horn manure for three acres or horn silica for many acres.

JPI’s used horns have already made repeated successful batches of BD 500 Horn Manure or BD 501 Horn Silica. JPI describes them as seasoned by prior preparation-making, and in JPI’s experience new horns often take an initial season to acclimate. A sound, previously used horn is a practical choice for another batch; keep horns reserved for BD 500 separate from those used for BD 501.

A sound cow horn can be reused for multiple batches, sometimes for several years; there is no fixed number of uses. Inspect it between cycles and stop using it when it begins to break down. Keep horns used for BD 500 separate from horns reserved for BD 501.
