Give your plant's roots the optimum environment in which to get started. Black Kow® cow manure contains millions of beneficial bacteria. These bacteria convert nitrogen and other nutrients into an easily available form for the plant. It is organic and contains nutrients that are released slowly without burning tender roots. These nutrients and moisture are held in the soil around roots until the plant needs them. Black Kow® has 10 times more nutrients than typical garden soil, and 4 to 6 times more cow manure than other brands.
