supplements that are relatively high in potassium (K) content:

                             N       P       K

    alfalfa meal            2.4%    0.2%    2.1%
    chicken manure (dry)    4.0%    4.0%    2.0%
    cow manure (dry)        2.0%    2.3%    2.4%
    kelp meal               1.5%    0.2%    2.5%
    soybean meal            7.0%    0.5%    2.3%
