Alternative waste management practices need to enhance the safe and economical production of layer chicken parent stock. An appropriate method to enhance safety and benefit is to reuse layer chicken parent stock litter as fertilizer for soybean production. Research was done to study the growth of soybeans, lipid, and protein content in seeds, and heavy metal content in leaves and seeds after the experiment. The experiment was conducted at an artificial housing constructed in Muang district, Ratchaburi province, Thailand from May to Sep 2006. The research comprised 6 treatments: pelleted layer chicken stock litter (PLCPSL) at rates 0, 0.02, 0.04, 0.06, 0.08 kg/pot mixture and chemical fertilizer (12-24-12) at a rate of 0.01 kg/pot were provided to soybean cultivar Chiang Mai 60 (CM.60). Results showed that PLCPSL could be used as fertilizer for soybean production with an optimum rate of 0.08 kg/pot mixture, which gave the best performance in terms of the number of nodes, height, dry matter accumulation, and total yield, exceeding the results obtained from using chemical fertilizer. Also, the nutrient content in the soil after the experiment increased as the PLCPSL content increased. Seed protein showed the highest level when using PLCPSL at a rate of 0.08 kg/pot, whereas seed lipids showed the lowest content. After the experiment, the heavy metal content (lead, cadmium and mercury) in the leaves was higher than standard values.
