I have completed a new pond approx. 1 acre in size..have some water in bottom with good clay bottom..I have read several post about "liming" a pond..Everyone around here including a reputable fish dealer said I did not need to do that in this area?? Question..I plan on filling the pond in the next month..I am in south central Texas...Is a soil test absolutely necessary? Also I plan on stocking it in March with BG and FH and catfish and starting a feeding program...Do I need to fertilize this new impoundment?
