it bugs me that the USDA helped fund the studying to come to the conclusion that it helps with drought, not proper use of tax dollars
The USDA funded the
entire study, which came to several conclusions. The drought tolerance was just one of several findings.
The study also shows that many plants (including potato, tomato, and corn) will yield food crops that are richer in vitamin C.
And more bio mass per seed, and higher germination rates.
If these plants can
also be grown with less irrigation, that is just icing on the cake.
I am curious to learn the techniques involved. I do know several people who use citric acid in their potting soil for tomatoes.
