Resumos

Determinou-se o zinco total, com ataque perclórico-fluoridrico e espectrofotometria de absorção atômica, em 227 amostras de 28 perfis pertencentes a 14 unidades representativas dos solos de São Paulo. O material de origem foi o fator preponderante a condicionar os teores de zinco dos solos. Os solos derivados de rochas básicas, os mais ricos em zinco, têm os teores médios ponderados dos horizontes A de seus perfis compreendidos entre 87 e 315 ppm; os derivados de materiais aluviais e coluviais, 53 e 84 ppm; os derivados de sedimentos modernos, entre 29 e 65 ppm; os derivados do arenito Bauru, entre 16 e 30 ppm; os derivados de sedimentos modernos arenosos, entre 1 e 17 ppm, os mais pobres em zinco. Observou-se boa correlação (r = 0,79**) entre os teores de zinco e os de óxidos de ferro dos solos.

Determinations of total zinc, extracted with HF-HClO4, were carried out in 227 samples of 28 profiles of 14 soil units of the State of São Paulo, using the atomic absorption spectrophotometry. The amount of zinc found in the different soils was mainly determined by the zinc content of the soil forming material. In soils derived from basic igneous rocks, those richest in zinc, the weighted average contents of their A horizons were between 87 and 315 ppm; in those derived from alluvial and coluvial materials the contents were 53 and 84 ppm; in those derived from modern sediments the contents were batween 29 and 65 ppm; in those derived from Bauru sandstone the contents were between 16 and 30 ppm and in 'those derived from modern sandy sediments, the contents were between 1 and 17 ppm. A significant correlation (r = 0,79**) was determined between the Fe2O3 end the total zinc contents in the studied soils.

SUMMARY

Determinations of total zinc, extracted with HF-HClO₄, were carried out in 227 samples of 28 profiles of 14 soil units of the State of São Paulo, using the atomic absorption spectrophotometry.

The amount of zinc found in the different soils was mainly determined by the zinc content of the soil forming material.

In soils derived from basic igneous rocks, those richest in zinc, the weighted average contents of their A horizons were between 87 and 315 ppm; in those derived from alluvial and coluvial materials the contents were 53 and 84 ppm; in those derived from modern sediments the contents were batween 29 and 65 ppm; in those derived from Bauru sandstone the contents were between 16 and 30 ppm and in 'those derived from modern sandy sediments, the contents were between 1 and 17 ppm.

A significant correlation (r = 0,79**) was determined between the Fe₂O₃ end the total zinc contents in the studied soils.
