Major characteristics of materials using in banana and pineapple nursery garden
Different materials using in banana and pineapple nursery gardens have different physical and chemical characteristics. Among studied materials, husk ashes are suitable to grow of banana and pineapple seedlings multiplied by cell plants. These ashes have important characteristics as following: bulk density is 0.16g/cm3, particle density is 1.04, porosity is 84.62%, equivalent to 14 and 15%, 36 and 35%, 1.34 and 1.45 times compared to Song Cau alluvial soils and re yellow soils respectively. pHKCl is 7 organic matter is 7.58%, while those of other materials are from 5.2 (pH) and from 0.58 to 1.29% (OM). Available N, P, K are all higher to those of other materials; particular available P is as high as 30mg/100g, while P of other materials is only from 1-10mg/100g.
