Little River, TX | Realize there have not been any studies on this so I am shooting in dim light. I used mineral data from Feeds & feeding texts.
Here is what I look for.
P (0.24%) .19 - .26%
K (1.9%) 1.68 - 2.52% <2.75% realizing the higher K levels have better stress tolerance.
Mg (.24%) .24 - .38%
Ca (1.35%) 1.10 - 1.83%
When any one of the cations K, Mg, & Ca becme too high or too low the others become out of wack also. For this I look at ratios.
N/K .9 -1.82/1
K/Ca 1.3 - 2.7/1
K/mg 2.9 - 11/1
Ca/Mg 3.3 - 7.0/1
Note potassium at 3.50% is where problems with milk fevor are thought to begin. | |
