Hello All,
 
I just got back the results from a nutrient analysis of potato leaves from =
our compost tea potato trial. The results indicate that the potato plants =
are low in K, Mg, Zn, and B. This also reflects our soil analysis. Can an=
yone suggest a good way to increase these nutrients via compost tea. Has a=
nyone ever put sulpomag into their tea brewer? Are there any products good=
 for tea that would have these nutrients in it?
 
Note: We did one representative sampling of each treatment (CT, nutrients w=
ithout compost, and no spray control) and had the potato leaves analyzed (I=
CP). The nitrogen levals were higher in the CT treatment 4.08%, lower in t=
he no spray control 3.89%, and lowest in the nutrient control 3.73%. Remb=
er this was only one sampling, but something seems to be making the nitroge=
n more available in the compost tea treatment.
 
Hope all is well,
