摘要

Soil remineralization is the utilization of mineral fines to restore soil fertility through Basalt dust from a rock quarry or glacial moraine fines from a gravel quarry were evaluated for their effects on nutrient availability in soils and on yields and composition of Lactuca saliva longifolia Malus sylvestris Zea mays Bonaf.), or tomato (esculentum Mill.). Experiments wereconducted on growers' farms and on the campus of the University of Massachusetts. Extractable soil K and Ca were increased generally, and some increases in extractable P, Fe, Mn, and Mg were detected in soils treated with basalt rock dusts. Soil acidity was decreased by about 0.5 pH unit by the additions of basalt dusts. Glacial moraine fines had a lesser effect on available plant nutrients than basalt dusts. Availability of nonessential trace elements was not affected by additions of mineral fines from either source. Plant tissue composition was not affected by any of the mineral treatments relative to treatments with fertilization with a commercial organic or chemical fertilizers. Yields of produce from crops produced with additions of mineral fines and composts generally were equivalent to those of crops grown with commercial fertilizers.
