Surface (0–15 cm) soils of four land uses (cropland, orchard, grassland, and fallow) were collected from four agroecological zones (AEZs) of Bangladesh with different OM content (AEZ-7: very low, −3: low, −9: medium, and −5: high). Bulk soils were physically fractionated into particulate and mineral associated OM (POM and MOM: >53 and <53
μ.m,分别为m。对OC和氮气(N)分析块状和分级的土壤。在土地使用中,未受干扰的土壤(草地和休耕地)总共突破(0.44-1.79%),而不是所有AEZ中的土壤(果园和农田)(0.39-1.67%)。POM和MOM级分中的OC和N的分布在土地用途中显着不同,并且也与天然祖含量变化。在所有AEZ中,农田土壤显示最低的POM-C含量(0.40-1.41%),而果园土壤显示出最高值(0.71-1.91%)。果实在休耕地和果园中最低(0.53-1.51%)的MOM-C最高(0.53-1.51%),农田具有中等金额(0.70-1.61%)。在农作物中,在妈妈池中分布相当数量的OC是明显的。这些发现表明,土壤中的总OC可以随着培养而降低,但不可避免地表明稳定池中的OC储存的损失。通过适当的土地使用和管理,可以增加具有高天然和低天然OM内容的土壤的碳储存电位。SN - 1687-8159 UR - HTTPS://Doi.org/10.1155/2020/8042961 Do - 10.1155 / 2020/8042961 JF - 国际农艺PB - Hindawi KW - ER -
