A Swiss chemist had discovered those properties of L.S.D. in 1943 and ten years later the C.I.A.
He sedated them for months at a time ("sleep therapy'), then "depatterned' them with massive electroshock treatment and frequent doses of L.S.D.; finally, he had them listen to tape-recorded messages, repeated up to a quarter-million times, during further periods of heavy sedation.
Harris Isbell, head of research at the Federal Addiction Research Center in Lexington, Kentucky, and the darling of such agencies as the National Institute of Mental Health and the Food and Drug Administration, also dosed human subjects with L.S.D. while on the C.I.A.
As research interest in L.S.D. grew during the 1950s, the C.I.A.
Gottlieb enjoyed lacing cocktails with L.S.D., and he did it at C.I.A.
enough so that it developed plans for using L.S.D. operationally.
By the mid-1960s nearly 1,500 military personnel had taken L.S.D. in tests run by the Army Chemical Corps.
Perhaps the most distinctive property of L.S.D. and its relatives is the extreme unpredictability of reactions to it.
At Stansbury there was no significant effect of subsoil amendment on soil moisture but there was a significant (P<0.001) effect of sampling date (at 0.2m, l.s.d.-0.0089; 0.6 m, l.s.d. = 0.023; and 0.8 m, l.s.d.
The ESP and EC were significantly (P<0.001) greater (ESP, l.s.d. 3%; EC, 1.s.d.=0.05dS/m) in the clay B horizon than the sandy A horizons (Table 3), but not at values that limit crop growth (maximum 0.17dS/m EC and ESP 12) (Peverill et al.
The main concern at this site was the significantly larger ESP values in the B horizon than the A horizon (P<0.001, l.s.d. = 2), which exceeded 15 by harvest time and would thus be considered to exceed the optimum for efficient water extraction by crops (Chhabra 1996).
At Stansbury, deep-tipping in 2007 combined with gypsum or nutrients produced a significantly lower penetration resistance than the control at 0.15-0.50m depth (P<0.001, l.s.d. = 0.53 MPa).
Dry matter (DM) weight at mid-tillering, grain harvest weight, and water use efficiency (WUE) at Stansbury (S) and Crystal Brook (CB) For each parameter, within sites, values followed by the same are not significantly different (l.s.d. at P = 0.05).
