摘要：Organic materials, such as fertilizers made from food waste and wood waste, are increasingly used in agricultural land. To control the emission of greenhouse gases, such as methane, dinitrogen monoxide and carbon dioxide, as well as water pollutants, to grasp material dynamics in farms is essential. Continuous research on the effect of bamboo powder made from thinned bamboos on soil environment in paddy fields have been conducted. In this study, the authors investigated temporal dynamics of nitrogen, phosphorus, potassium, calcium and magnesium in test columns filled with bamboo powder manured paddy soil. Experimental results revealed the fact that growth of rice affected concentrations of these materials. However, direct effect of bamboo powder on material concentration was not clear.
