Too much calcium & magnesium
I've had a lot of problems the last few years with my tomatoes rotting on the vine. The leaves yellow and drop off early, etc. I've grown mainly heirlooms (Brandywine, Cherokee Purple, Sweet Million), but even tried a disease-resistant variety with no better results. I do not grow them where tomatoes or peppers were grown the prior season. Wondered if I had too little calcium.
So, sent off a soil sample to the Extension service and got the following results:
pH 7.6, silty soil
N says to add .30 lb/100 sq. ft.
P 126 (25-40 sufficient)
K 107 (120-180 sufficient)
Calcium 3031 (601-1000 optimum)
Magnesium 545 (101-500 optimum)
organic matter 7.5%
I am mystified by the high calcium. Last spring I put some well-rotted sheep manure/straw on the garden for the first time. That was the only fertilizer I used.
Any suggestions? How do I correct the high calcium? Thanks!
