Heres the problem: I got my soil test back from the covered part of my patch yesterday. Sodium is too high, the soil scientist recommended 5 lbs of gypsum per 100/sq ft. When I spoke to him today he said what would be ideal would be if I over a period of time I could simulate 3" of rain. This part of the patch is 308 sq ft. Does anyone have any idea how gallons of water it would take to simulate 3" of rainfall over 308 sq/ft. I have already hit the patch with about 170 gallons of water but I am sure that this is no where near enough. thanks KathyT

One inch is 27,000 gallons per acre which is 620 gallons per 1000 sq ft. You have a thrid that so 191 gallons per 300 sq ft per 1 inch.

Hence you need about 900 gallons of water to deliver 3 inches.

Kathy,

Before you go using your water, find out where the sodium is coming from. Most likely it is your own water source. By adding gypsum, it will not solve your problems.

Na is VERY bad for our plants. It becomes a dominant cation and doesn't let Ca into the plant.
