EWEST,
100% agree. I can't describe in scientific terms like you did, but in plain English, in my ponds, adding ag. lime is critical..and as most know, I do not fertilize. The ag. lime has the effect of a catalyst by enabling far more efficient utilization of nutrients in the water. I learned about ag. lime's effects on my soil many years ago when I discovered that my hay fields actually produced more hay with lime and without fertilizer than with fertilizer and without lime.
In our acidic soils of East Texas, ag. lime is magic on hay fields, gardens, and especially ponds. I'll never be without it.
