Abstract

Land use in Bogor Regency has diverse vegetation and different soil characteristics. Soil characteristics have an influence on land management. Improper land management has led to a decrease in microbial populations, biodiversity and a decline in soil quality and fertility. Soil fertility is produced by the interaction of the physical, chemical, and biological properties of the soil. This study aims to determine the correlation of soil biological and chemical properties in several different types of land use in Bogor Regency. Soil sampling was carried out using the purposive random sampling method with five replicates. Soil samples were taken at a depth of 0-20 cm by ±1 kg. The research site includes eight land uses namely bamboo gardens, sengon gardens, lamtorogung gardens, and dragon fruit orchards. The results of the analysis showed that the dragon fruit field had an acid pH with very high organic C and total N levels with the highest fungal population of 2.27 x 105 CFU g-1. Meanwhile, bamboo fields with an acid pH also have a medium organic C content and low total N with the lowest total fungi population of 0.37 x 105 CFU g-1. Azotobacter populations and respiration values had the highest correlation with the total P content of the soil. The correlation value of the total population of fungi was the highest, with a total N levels of 0.427.

分析茂物区不同类型土地使用的土壤的生物和化学性质

茂物摄政的土地利用具有不同的植被和不同的土壤特征。土壤特性对土地管理有影响。不当的土地管理导致微生物数量减少，生物多样性减少，土壤质量和肥力下降。土壤肥力是由土壤的物理、化学和生物特性相互作用产生的。本研究旨在确定茂物县几种不同土地利用类型下土壤生物和化学特性的相关性。土壤取样采用有目的随机抽样法，共5个重复。在0 ~ 20 cm深度±1 kg处取土样。研究地点包括8个土地用途，即竹园、仙根园、龙宫园和火龙果园。分析结果表明，火龙果田酸性pH值较高，有机碳和全氮水平较高，真菌数量最高，为2.27 × 105 CFU g-1。同时，酸性竹田有机碳含量中等，全氮含量较低，真菌总数量最低，为0.37 × 105 CFU g-1。固氮菌数量和呼吸值与土壤全磷含量的相关性最高。真菌总居群的相关值最高，总氮水平为0.427。
