Deposition of heavy elements on Belgian agricultural soils.

Navarre J.L. | Ronneau C. | Priest P.
A network of 19 rain gauges was set up over Belgium in agricultural zones. Determination of heavy metals content of water samples collected during a 1 yr meteorological cycle allowed to estimate wet plus dry deposition rate of many toxic metals over the country. It appears that soils contamination by deposition exceeds contamination through the use of chemical fertilizers.

This investigation was conducted to determine the elemental composition of effluents from three anaerobic swine waste lagoons and one aerobic swine waste lagoon and to evaluate effects of effluent application on growth of corn (Zea mays L.). Wide variation occurred in the elemental composition of effluents among the four lagoons and among four sampling dates from each lagoon. Use of these effluents as irrigation water would lead to application of a wide range in amounts of nutrients to soil. Effluent application increased corn grain yield on a Woodstown loamy fine sand. This yield increase was attributed to alleviation of moisture stress and to correction of N deficiency.
