Undisturbed B horizon cores showed a smaller decrease in percolation rate than the A horizons, but natural gypsum or carbonates were of no benefit in maintaining percolation through the unamended contaminated subsoils. Percolation g&quot;n&quot;.uily increased as more ca-amendment was added to the contaminated A horizons, but rate of (surface-applied) amendment had no effect on the percolation throush the B horizon cores. Gypsum mixed into the contaminated soll was much more-eflective than gypsum applied on the surface; adding NH1NO, to the gypsum had no effect. The efficiency of incorporated amendments decreased in the order: gypsum &gt; MgSO, &gt; Ca(NO,)r. Surface-applied Ca(NOr). was a better amendment than mixed-in Ca(NO.,)r. kaching losses decreased in the order: Cl &gt; Na &gt; Mg &gt; Ca &gt; K. Initial losses of Cl, Na, Mg and Ca were faster than expected from the rule of thumb that one pore volume of water reduces the salt content by about one-half. Subsequently, losses were much slower than in the rule of thumb as most of the remaining cations are in exchangeable form.</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue><custom3><style face="normal" font="default" size="100%">http://www.worldcat.org/oclc/4663077247</style></custom3><custom4><style face="normal" font="default" size="100%">OSEMB</style></custom4></record></records></xml>
