The objective of this study was to evaluate a fluxing salt residue (slag) produced 1n large quantities by a Mg reclamation process as a potential K-Mg nutrient source (41% KC1, 33% MgO and 3.2% MgCl2) for cereal crops 1n the Pacific Northwest. Field studies were conducted at Sandpoint, Idaho in 1983 and 1984 to evaluate this fluxing salt residue on the following three criteria: (1) potential phytotoxicity problems associated with plant growth, (2) response (yield) of spring wheat (Triticum aestivum L.), spring barley (Hordeum vulqare L.) and oats (Avena sativa L.), and (3) comparison with commercial K and Mg fertilizers. Evidence of possible phytotoxicity problems associated with plant growth 1n the field was never observed at fluxing salt residue application rates up to 1980 kg/ha. When applied to soils deficient in K and Mg, the waste residue material Induced yield increases up to 21.7, 54.0 and 50.0% of spring wheat, spring barley and oats, respectively. When applied at rates in excess of 660 kg/ha, the residue significantly increased levels of K and Hg in soils in 1983 and 1984. The residue compared favorably with commercial K and Hg fertilizer sources by producing similar cereal yields and soil test K and Hg values. |
