化肥、杀虫剂和其他化学品等生产投入用于实现最大经济产量。然而，农业发展战略必须侧重于提高土壤生产力，降低生产成本，提高投入效率，同时不损害环境。这项研究涉及在保护和维持环境的同时利用经济上可行的创新技术。爆坂石是一种矿物，它以其巨大的孔隙率，高吸收能力和额外的负电荷而与众不同。本研究的目的是确定不同水平的Bakuhan seki对土壤质量和大豆生长及产量的影响。日本和中国的日本和中国株式会社在实验开始时和收获后收集土壤样品，并分析其化学性质。所有级别的Bakuhan seki控制大豆的生长，如延长收获成熟期，增加种子直径和百粒重。Bakuhan-seki同样保留了土壤中的养分，如CEC的相对增加和土壤中的钙和镁的适度增加所示。此外，还改善了土壤环境，提高了植物吸收NO3-N的有效性，从而提高了产量。
Production inputs such as fertilizers, pesticides and other chemicals are used to achieve maximum economic yield. Agricultural development strategy, however, must be focused on increasing soil productivity with reduced cost of production and higher efficiency of inputs with no harm to the environment. This study deals on the utilization of innovative techniques which is economically feasible while protecting and sustaining the environment. Bakuhan-seki stone is a mineral which had been distinct for its enormous porosity, high absorption capacity and has an additional negative charge. The objectives of this study were to determine the effects of different levels of Bakuhan-seki on soil quality and on growth and yield of soybean. Japan and China Bakuhan-seki were added into the soil at the rate of application as follows: 1.5 kg/m 3 , 3 kg/m 3 , 5 kg/m 3 and control (no Bakuhan-seki). Soil samples were collected at the start of the experiment and after harvest and were analyzed for chemical properties. All levels of Bakuhan-seki control growth of soybean as shown in the prolonged harvest maturity date, increased seed diameter and 100-seed weight. Bakuhan-seki likewise retained nutrients in the soil as shown in the relative increase of CEC and moderately higher calcium and magnesium in soil. Addition of Bakuhan-seki also improved the soil environment and enhanced availability of NO 3 -N for plant uptake, thus resulting to increased yield.
