Abstract:

The effects of repeated applications of Municipal Reclaimed Wastewater (MRWW), compared to that of normal irrigation water, on the macro and microelement status of a clay loam (CL) soil and the plants were studied in a randomized block design in a greenhouse of the Department of Environmental and Natural Resources Management, Ioannina University, Agrinion-Greece. The soil was cultivated with onion (Allium cepa) and lettuce (Lactuca sativa). The planting of lettuce and sowing of onions was done early in March 2004, and the growth period lasted till the beginning of June (end of irrigation period). Soil and plant samples were taken three weeks after planting and at the end of the growth period. Normal irrigation water, MRWW, soil, and plant samples were analysed, and the data obtained were accordingly studied. The following effects were found: The macro and microelements accumulated in the soil and plants to varying degree, depending on the kind of element and plant. Among macro-elements, the highest accumulation, mainly in the soil and less in the plants, was that of P, while the accumulation of K was rather limited. Among microelements, Mn accumulated mostly in the soil, whereas Cu mainly in lettuce roots, and secondly in leaves and seeds, but not in the onion plants. Also Zn accumulated mainly in lettuce seeds. The content of macro and micronutrients of the studied plants was mostly directly related to their respective accumulation in the soil. This relationship, however, was modified by: (a) the size of the element's accumulation in the soil, (b) the physical characteristics of the soil, (c) the interaction among the accumulated elements, (d) and the genotypical characteristics of the plants.
