In general a pH of at least 6 is desirable for row crops and at least 6.9 for alfalfa. A pH of 7 is considered neutral, below 7 is acid and above 7 is alkaline. Applying lime raises the pH. The calcium in the lime has a buffering effect but needs to be mixed with the soil for full benefit. A representative sample is important in soil testing. . A pond can be very desirable if located in the right place.
Size is a consideration.
Size will depend on the intended use and land area available to drain into the pond. Unless the pond is fed by a spring each acre of pond surface requires a bout 20 acres of drainage area above the pond. Soils are important in pond construction. It appears that this year is a better nut year than last year. There are different treatments for nut growing depending on the species.
