Fertilizer: PPM N / TDS

Post by Ray Barkalo » Thu, 06 May 1999 04:00:00

I don't know which method is better for determining the amount of
fertilizer one should use, but the nitrogen concentration and total
dissolved solids levels are pretty common, so I've put together a simple
estimation calculator that's now publicly available on our website.

Please check it out - along with our other offerings.
