Frank –

It is my understanding that the “do NOT feed to Ruminates” statement on bags of bone meal comes from concerns over mad cow disease. However, I am not certain of this.

Both Rock Phosphate and Bone Meal are good sources of organic phosphorous for home gardeners. We recommend using bone meal as a short term phosphorous supply and rock phosphate as a long term phosphorous supply, as it’s slower to break down. Many growers often combine the two to get the benefits of both and a more complete range of micronutrients.
