Abstract

Understanding soil characteristics is important to determine the alternative strategies of land management, particularly those related to the scheme of soil and water conservation. This study investigated soil characteristics from four land covers around the coal mining concession area located in South Kalimantan. A soil survey was conducted using a purposive sampling method with three replicates in each land cover. Soil samples that were taken at depths of 0-10 cm, 11-20 cm, and 21-30 cm, were composited before being brought to the laboratory to quantify their characteristics, such as texture and organic carbon content. Data analysis was processed using a non-parametric test with a significant level of 5%. Comparison average of soil characteristics between land covers was evaluated using the Kruskal-Wallis test and followed by Nemenyi-test. Results found that soil characteristics from four land covers significantly differed in texture and organic carbon content. The highest sand fraction was noted in shrubs (67.23±0.86%), while the greatest silt fraction was recorded in plantation forests (29.71±2.84%). Compared to other land covers, the clay content in plantation forests and reclamation area was relatively equal by around 53-54%. On another side, The highest soil organic carbon was found in plantation forests with ranging of (4.44±0.14%) followed by natural forests (4.24±0.62%), shrubs (3.38±0.09%), and reclamation area (1.14±0.09%). These findings indicated there were high variations of soil characteristics from different land covers around the coal mining concession area. Therefore, it is recommended for managers to apply adaptive strategies in supporting soil conservation efforts based on the soil characteristics in each site.

Abstract

Biochar enriched with fertilizers has the potential to improve the quality of acid soils. In the agricultural sector, it was reported that the sap of Kappapychus alvarezii (K-sap) is often used as a biofertilizer. Therefore, this study aimed to (i) examine the character of biochar enriched with the K-sap and (ii) analyze the soil quality after incubation. This study was carried out using two treatment factors arranged in a randomized block design, namely the biochar dose at 0%, 2.5%, 5.0%, and 7.5% in weight and K-sap at concentrations of 0%, 5%, 10%, and 15%.  Ten kilograms of acid soil were incubated with K-sap enriched biochar for up to 2 weeks in each experimental pot. The results showed that the absorption band increased with the K-sap concentration for the functional group associated with the OH-stretching of the biochar enriched with K-sap was stronger and wider than the unenriched. The peak elevation pattern detected by X-ray diffraction for all biochars was similar. The dosage of 7.5% biochar enriched with 5%-10% K-sap concentrations increased pH, EC, organic C, total N, C:N ratio, available P, and exchangeable K, Ca, Mg, and Si than those without treatment. Furthermore, ammonium and total spores of arbuscular mycorrhizal fungi decreased, flagellates increased with and without the biochar, while the nitrate, total bacteria, and fungi of all treatments were similar. Based on these results, it was concluded that biochar enriched with K-sap could improve the quality of acid soil.
