Bio agent added organomineral nitrogen fertilizer for heavy metal contaminated paddy field treatment

Year: 2019

Type: conference-paper

Abstract: Industrial waste in paddy field leads to accumulation of heavy metals in the soils. The availability of heavy metal on the soil can affect soil quality and plant growth. The objectives of this research were to obtain the best dosage of bio agent-added organomineral nitrogen fertilizer (ONF+BA) for the improvement of soil quality and paddy rice grown in industrial-waste contaminated soil. Randomized block design were applied with six single treatments: 150 kg ONF+BA (A), 200 kg ONF+BA (B), 250 kg ONF+BA (C), 300 kg ONF+BA (D), 350 kg ONF+BA (E), 250 kg urea (F), each treatment was replicated five times. The result showed that the application of ONF+BA reduced lead (Pb) and chrome (Cr) solubility and foliar accumulation, improved plant growth, and increase foliage nitrogen content. The doses of 300 kg ONF+BA shown highest lead and chrome solubility reduction, while 350 kg ONF+BA decrease foliar accumulation of lead and chrome.
