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

Mercury composite and cyanidation are gold mining methods that are frequently used. The mercury composite method produces tailings containing heavy metals that can harm living organisms. Utilisation of tailings for the development of forage may be enhanced through arbuscular mycorrhizal fungi (AMF) inoculation to increase plant resistance, absorption of macro and micronutrients, and reduce levels of metal contaminants in the tailings. This study aimed to investigate the effect of arbuscular mycorrhizal fungi on nutrients and heavy metals uptake by Pennisetum purpureum cv Mott in phytoremediation of gold mine tailings. Treatments consisted of four levels of AMF inoculation (0, 5, 10 and 15 g pot-1) were arranged in a completely randomised design with five replications. Each pot contained 3 kg of tailings. The results showed that the best crude protein, crude fiber, crude fat, Ca, and P contents in the plant shoots was obtained by providing AMF inoculation of 15 g pot-1. However, the treatment had no significant effect on dry weight, dry matter, and nitrogen-free extract. AMF significantly increased the uptake of heavy metals by the plant roots. The treatments did not significantly affect Pb uptake by plant roots and shoots and Hg uptake by plant shoots. AMF treatments significantly reduced the translocation factor (TF) value for Hg, bioconcentration factor (BCF) values for Cd and Pb, and removal efficiency (RE) values for Cd and Pb. AMF could effectively increase nutrient absorption in the plant shoots, reduce Cd, Hg, and Pb translocation in plant shoots, and reduce Cd, Hg, and Pb in the tailings.

Abstract

Fertilisers, especially those containing NPK nutrients, have become a necessity in farming both rice fields and dry land. Most of the application of fertilisers is based on plant commodities and less based on the nature of the diversity of the soil or growing media. This study aimed to determine the balance of NPK nutrients and the nutrient elements that became the limiting factor in the rice and dryland maize cropping systems. The study was conducted at a rice field in Jember District and on dry land in Bogor District with maize plants. The fertiliser used is organic fertiliser. Nutrient balance is obtained by calculating the difference between the total input of nutrients N, P, and K given and the total output of nutrients N, P, and K transported by plants. The results showed that the combination of fertilizing treatment with biochar (50%), fish waste (25%), and chicken manure (25%) up to 10 t/ha on rice field soil at the experimental location in Jember had to limit factors for plant growth: low organic matter content, trace elements essential nutrients N and P are also low. Likewise, the combination of inorganic NPK fertiliser treatment with organic fertiliser up to 600 kg/ha on dry land in Bogor has not been able to improve its fertility status with limiting factors: low organic matter content, low N-total, and low exchangeable K.

Abstract

The decline of land quality has an impact on the decline of productivity which in turn reduces production. This kind of thing happened to rice fields in the research area of Seririt District. The objective of this study was to evaluate the rice field quality in Seririt District, Buleleng Regency, Bali Province. The study used a survey method to take soil samples, followed by laboratory analysis for each homogeneous land unit (HLU). The HLU was determined by overlapping soil type maps, slope maps, and utility maps. Parameters analysed were bulk density, texture, porosity, water content, organic C, pH, cation exchange capacity (CEC), base saturation (BS), nutrients (total N, available P, and available K), and biomass C. The results of the laboratory analysis were compared with the criteria for soil quality based on ten minimum data sets (MDS) for each HLU. The results showed that the soil quality at the study site is classified as very good in HLU I with a soil quality index (SQI) of 18. This HLU is located in Rangdu and Ringdikit villages, with an area of 125.15 ha. Good SQI was observed on HLUs II, III, IV, V, VII, and VIII, respectively, located in Banjar Asem, Lokapaksa, Pangkung Paruk, Bestala, Ume Anyar, Mayong, Joanyar, the SQI value of 22-25 is 2,321.49 ha with the limiting factors of total N, total P, texture, and bulk density. The suggested rice field management plan is the addition of organic, nitrogen, and phosphate fertilisers.
