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.

Tuban Regency feels the impact of climate change on various economic supporting sectors. This makes the adaptation efforts in these sectors important as well as climate change mitigation to support the reduction of greenhouse gas emissions, one of which is by maintaining the existence of production forests. This study aims to identify the amount of carbon uptake by the two main plants. The method used is tree diameter data collection without harvesting. The diameter data is used to calculate biomass and carbon sequestration with allometric equations. The results showed that teak had the lowest biomass value produced at the age of 5 years at 94.26 t ha-1, and the highest biomass was recorded at the age of 10 years at 200.33 t ha-1. Meanwhile, mahogany at the age of 5 years, 10 years and 15 years had a total biomass of 40.76 t ha-1, 53.55 t ha-1 and 146.37 t ha-1, respectively. From the biomass value, the total carbon stored in teak aged 5 years, 10 years and 15 years, respectively, was 43.36 t ha-1, 92.15 t ha-1 and 90.05 t ha-1. While the the total carbon stores in mahogany aged 5 years, 10 years and 15 years respectively was 18.75 t ha-1, 24.63 t ha-1 and 67.33 t ha-1. The teak and mahogany production forests in this age group have a total area of more than 280 ha, so that the total carbon sequestration at BKPH Sundulan is 78,471 tons C from teak production forests and 1,835.3 tons C absorbed from mahogany production forests.

Rice production in Pamekasan Regency from 2011 to 2019 decreased by 38.71% due to farmers applying fertilizers that did not match plant needs, such as insufficient application of manure, organic fertilizers and other inorganic fertilizers. In addition, the basic fertilization obtained by farmers comes from informal information, so the application of fertilizers on the land is not efficient. Efforts have been made to overcome these problems by evaluating soil fertility from the aspect of nutrient retention as a basis for determining fertilizer requirements. The purpose of this study was to evaluate soil fertility, especially from the aspect of nutrient retention in paddy fields in Pamekasan Regency. This research used a purposive random sampling method based on SPL (Land Map Unit). Parameters observed were cation exchange capacity, organic C, base saturation, pH, electrical conductivity, texture, porosity, bulk density and saturated hydraulic conductivity. The results showed that the high level of soil fertility in Pamekasan Regency was found in cation exchange capacity in Tlanakan District (43.92 cmol kg-1), base saturation in Galis District (99.38%), pH in Tlanakan District (7.00), electrical conductivity in Pakong and Pasean districts (0.39 mS) and the dominant texture is the clay fraction. Low fertility levels are found in soil organic C in Waru and Kadur Districts (0.08%), bulk density in Pasean District (1.59 g cm-3), porosity in Proppo District (34.89%), and saturated hydraulic conductivity in Pasean District (46.34 cm hour-1).
