Abstract

Six vegetable species, broccoli, cabbage, lettuce, eggplant, pepper, and tomato plants were grown for 8 wks on a medium of composted sewage sludge (compost), perlite, and peat (equal parts by volume). P, Ca, and Mg were adequate for the growing period, but accumulation of N and K did not increase after the 6th wk after transplanting. Cabbage and broccoli accumulated greater amounts of N and K from the medium and could be successfully grown in the medium without supplemental fertilization. Zn and Cd, potentially hazardous heavy metals present in compost, did not reach excessive levels for either plant nutrition or human consumption.
