Blood meal
Blood meal is a nitrogen-rich , fast-acting, organic fertilizer made from slaughterhouse waste .
Blood meal belongs to the group of animal meal . It is dried, ground blood and contains approx. 12% nitrogen compounds , 80% proteins and many trace elements . Blood meal can be applied directly to the soil in liquid form. Although according to all previous knowledge there is no risk of BSE , it should no longer be used in organic farming and was banned as animal feed in 2001. It should be noted that amendments to Regulation (EC) No. 999/2001 later relaxed the feed ban regulations. For a number of years it has been possible to use blood products (with the exception of blood meal itself) as supplementary feed in pig and poultry feed, subject to certain conditions and requirements.
