Ultisol is one type of soil that has a very wide distribution in Indonesia, but the use of this soil faces many obstacles. The main problem in ultisol utilization is the low availability of phosphorus (P) and the low absorption efficiency. Coal fly ash (CFA) is a material that can overcome these problems. The objective of this study was to examine the effect of Application CFA on several soil chemical properties (pH, exchangeable Al, exchangeable Ca and available P), plant growth, yield, and absorption efficiency of P fertilizer. This study used a completely randomized factorial design consisting of two factors. The first factor was CFA that consisted of three levels of treatment, namely: A0 = 0 t ha-1 or without CFA, A1 = 40 t CFA ha-1, A2 = 80 t CFA ha-1. The second factor was P fertilizer that consisted of four levels of treatment, namely: P0 = 0 kg ha-1, P1 = 30 kg P ha-1, P2 = 60 kg P ha-1 and P3 = 90 kg P ha-1. The results of the study showed that the application of 80 t CFA ha-1 increased the pH by 13.41%, reduced exchangeable Al by 59.53% and increased exchangeable by Ca 192.66% compared to control. The combination 80 t CFA ha-1 and 90 kg P ha-1 increased available P by 986.79% compared to control. The application of 80 t CFA ha-1 resulted in the highest total plant dry weight and total P uptake. The treatment resulted in total plant dry weight of 172.96 g and total P uptake of 187.62 mg plant-1, increased 62.39% and 100.21% respectively compared to the control. The application of 90 kg P fertilizer ha-1 resulted in the highest total dry weight of maize, and total P uptake, namely 167.49 g and 174.39 mg plant-1, respectively, which means that the total plant dry weight increased by 51.00% and the total uptake P increased 69.79% compared to control. The highest seed dry weight was obtained in the combination of 80 t CFA ha-1 and 90 kg P ha-1, namely 39.33 g, an increase of 715.53% compared to the control. The combination of 40 t CFA ha-1 and 30 kg P ha-1 resulted in the highest absorption efficiency of P fertilizer, namely 30.43%. This means that in this treatment, maize can absorb 30.43% of the applied P fertilizer.

Entisol of Wajak Malang has low base saturation and organic matter and slightly acid. The result of the analysis also showed that soil has nutrient P with high criteria; however, N, K, Ca, Mg, Na contents are low to very low criteria. Application of humic acid at the first planting can leave residual nutrients and can still be used in the second planting. Besides urea-humic, goat manure can also be because it can improve soil properties, organic matter and nutrients contents. The purpose of this study was to explore the effect of the application of urea-humic residue with goat manure on the availability of phosphorus, potassium and the growth of okra on an Entisol of Wajak Malang. The combination of treatments consisted of: U1 (soil residue urea-humic 100% + goat manure), UH1 (soil residue of urea-humic 75% + goat manure), UH2 (soil residue of urea-humic 100% + goat manure), UH3 (soil residue of urea-humic 125% + goat manure), UH4 (soil residue if urea-humic 150% + goat manure). The five treatments were arranged in a completely randomized design with three replicates. The results showed that urea-humic residue with application goat manure had no significant effect on available P, exchangeable K in the soil, plants height and leaf number of okra on 4, 6 and 8 weeks after planting.

Demand for the consumption of soybeans in 2014 was very high amounting to 10.91 kg capita-1 year-1 while soybean production was only 955 thousand tons. Soybean production can be increased by expanding the planting area including saline land areas. The use of soil microbes Rhizobium sp can help overcome this because Rhizobium sp can find symbiosis with soybean plants so that it allows the absorption of nitrogen nutrients for the growth of soybean plants. This study was aimed to determine and analyze the effect of saline soil on the effectiveness and infectivity of Rhizobium sp. inoculated to soybean plants on soil chemical and biological properties and plant growth. The study was conducted using a randomized block design consisting of 10 treatments and 3 replications. The results showed that the bacterial inoculation gave better plant growth than the control treatment on saline and non-saline soils. The high number of colonies was able to increase the number of effective root nodules and N-plant uptake and produced good plant growth with the best results. The inoculation treatment of isolate 12 on non-saline soil yielded N absorption value of 0.32 g plant-1, effective root nodules of 87.67 g plant-1, effective root nodule dry weight of 0.74 g plant-1, and plant height of 134.3 cm. Â On the biological properties of isolate 12 inoculation treatment on non-saline soil had the highest yield for the number of isolate colonies of 305.45 Ã— 105 CFU mL-1.

Soil acidity is the dominant factor in the phosphate amount, distribution of nutrients in the aggregate is important to supporting nutrient requirement and cycling. Furthermore, Al-P and Fe-P or Ca-P bonds trapped in soil minerals, also physically protected from loss due to associate with aggregates. Thus, the factual limitation of phosphorus becomes a topic, including various aggregate fractions changes and their effect on the slope. Soil samples were taken from 36 years old plantations consisting of 45 points with two depths (0 - 20 cm and 20 - 40 cm) on a various slope, soil samples fractionated into several aggregate fractions, namely micro (<250 Âµm), meso (250-2000 Âµm) and macro-aggregates (2,000-5,000 Âµm). For chemical analysis, soil pH was measured by pH meter, aluminium with the volumetric method, and P-available with Bray method. Based on the analysis, it is known that the P content in the meso aggregate is higher than P content in the macro aggregate Â± 0.055 g m-2 for 0 - 20 cm Â± 2.136 g m-2 for 20-40 cm depth, and Â± 1.058 g m-2 for slope of 0-8% at 0-20 cm depth. In total, phosphate in the tea plantation area is very low.

Peatlands have specific characteristics, namely irreversible drying, so that become flammable. Peat fires have an impact on changes in soil pH. The study aimed to analyze the soil acidity after peatland fires in oil palm plantation. This study used a survey method on two main plots (low and high fire intensity). Samples were taken at two soil depth including 0-10 cm and 11-30 cm in three zones (fertilization area, harvest path and frond pile zone) and repeated three times. Data were analyzed by ANOVA using the 5% nested test, then LSD test, and analyzed for correlation. The results showed that the soil pH on all land was included in the very acid category. Soil pH in the land B (land with high fire intensity) is higher than those in the land A (land with low fire intensity), both in top soil and sub soil. The micro-nutrient elements of Fe and Al in the land B are lower than land A, while the micro-nutrients of Mn in land B are higher than land A. The correlation of soil pH towards Fe and Al is negative, while for Mn is positive (pH increases, acid cations of Fe and Al will decrease while acid cations of Mn will increase). This was presumably due to competition in occupying the land-catchment complex.

The area of peatland in Indonesia is estimated at around 13.2 million hectares, which about 5.7 million hectares are found in Kalimantan. Peatlands have many functions such as for water conservation, reducing floods, supporting various kinds of biodiversity, and climate control. However, in 2015 there was a decline in the quality of peatlands, which was triggered by fires that scorched 583.833 hectares in Central Kalimantan. If the fires occur continuously, land degradation will increase and the peat ecosystem will be disturbed. Given these adverse effects, it is necessary to protect an area from fires early by providing a map of forest fire hazard by utilizing geographic information system using scoring and weighting methods. In the making of the map, a combination of natural factors and human factors that were considered as factors in the occurrence of fires were land cover, peat maturity, village centres, road and river networks as well as the central operational-area which later were analyzed with hotspot data. This research was conducted in one of the sub-districts that are considered to have a high level of vulnerability, which was in Jabiren Raya District, Pulang Pisau Regency, Central Kalimantan. The results showed that most of the study areas had a moderate level of vulnerability with the triggering factors of fire was land cover, peat maturity level, and road network.
