| 词条 | Blood meal |
| 释义 |
Blood meal is a dry, inert powder made from blood, used as a high-nitrogen organic fertilizer and a high protein animal feed. N = 13.25%, P = 1.0%, K = 0.6%. It is one of the highest non-synthetic sources of nitrogen. It usually comes from cattle or hogs as a slaughterhouse by-product. UsesDietary supplementBlood meal can be used as a livestock dietary supplement and is mainly added to supply dietary lysine for cattle, fish and poultry.[1] Prior to use, it is sometimes mixed with molasses.[2] Organic fertilizersBlood meal, bone meal, and other animal by-products are permitted in certified organic production as soil amendments, though they cannot be fed to organic livestock. Blood meal is different from bone meal in that blood meal contains a higher amount of nitrogen, while bone meal contains phosphorus. Alternatives to Blood Meal include feather meal and alfalfa meal.[3] Blood meal is sometimes used as a composting activator.[4] Pest controlBlood meal can be spread on gardens to deter pest animals such as rabbits. The theory is that the animals smell the blood and are repelled by the odor.[5][6] ProcessingBlood needs to be dried before being used as blood meal. Several drying methods are available: solar drying, oven drying, drum drying, flash drying or spray drying.[7] See also
