Two different types of coal fly ash-based pellet aggregates (PA) with 5 mm [small PA (SPA)] and 10 mm [large PA (LPA)] diameters were produced from coal fly ash (CFA) and paper waste (PW). Both types of PA were utilized as soil amendments to enhance poor physicochemical properties of problematic grey soil in Okinawa, Japan for the cultivation of Brassica campestris. Grey soil was amended with SPA alone, LPA alone and both SPA and LPA. The growth and yield parameters of Brassica campestris were determined. PA addition as a soil amendment improved the physicochemical properties of the amendment mixtures compared to grey soil without any amendments. Moreover, PA addition increased the growth and yield parameters of Brassica campestris compared to grey soil control. It can be concluded that PA can be utilized as a soil amendment to improve the crop production in problematic grey soil in Okinawa, Japan. [ABSTRACT FROM PUBLISHER] |
