A “swamp culture” regime in which water grass was grown for several months under very moist conditions has proved to be an important factor in the reclamation of an alkali soil of the Hacienda series.
Gypsum applications of 4.22 and 12.47 tons per acre and sulfuric acid applications of 3.59 and 6.95 tons per acre, in conjunction with the swamp-culture pretreatment, showed marked beneficial effects on the subsequent growth of alfalfa.
Statistically, the sulfuric acid applications were more effective than the gypsum applications, although there were no significant differences in yield between the high and low acid treatments nor between the high and low gypsum treatments. This suggests that lower applications than 3.59 tons of sulfuric acid and 4.22 tons of gypsum may I be equally effective.
