Soil physical and chemical properties are the main factors that significantlyinfluence vanilla production. This study aimed to identify the soil’s physicaland chemical properties, determine the soil fertility status, and evaluate the soilsuitability for vanilla plants cultivated at three villages in Tinangkung UtaraDistrict. This research has been carried out at the long-term monoculture of thevanilla plantation. The soil fertility properties have determined based onphysical properties such as texture (pipete method) and chemical propertiessuch as pH, organic C content (Walkey and Black), P2O5 (olsen) and K2O(HCL25%), base saturation/KB dan cation exchange capacity/CEC ) NH4OAcpH7). The data then matched to PPT soil fertility and BBSDLP land evaluationcriteria for the vanilla plant. The result showed that the soil in the study sitehas clayey texture, neutral soil reaction, moderate KB and P2O5, and moderateto high CEC. On the other hand, the soil exhibited lower content of organic Cand K2O. Despite soil fertility status determined as low, the evaluation analysisresulted marginally suitable, which could be optimised to highly suitable.

From the pyrolysis process, biochar is a carbon rich and recalcitrant organic material with potential for long term carbon sequestration because of its aromatic structure. However, the physical and chemical properties of the biochar vary due to the diversity of raw material and the conditions of production. The present study aimed to evaluate the biochar from the sugarcane bagasse at different temperatures and under two conditions of pyrolysis. The biochar was produced at two final temperatures 200°C (1 hour); 250°C (1h) and 250°C (2h), with pyrolysis of an oxidizing and non-oxidizing atmosphere for both. PH, cation exchange capacity (CTC), carbon content (C), Nitrogen (N), hydrogen (H), H:C, C:N and ash ratios were evaluated. The contents of C, H, N and the atomic ratios H:C and C:N were higher in Biochar produced in a non-oxidizing atmosphere (BNO). However, the content of ash, pH and CTC were higher in Biochar produced in oxidizing atmospheres (BO). One can conclude the direct influence of the pyrolysis condition.

ABSTRACTThis study aims to determine the effect of the location distance from the river bank and the depth ofsoil layer to the soil chemical properties in the tidal land area. The study was conducted in April untilJune 2016 in the tidal areas of Bajarum village, District of Kota Besi, East Kotawaringin, CentralBorneo Province. The study used survey methods and soil sampling in the field, analysis of soilsamples in the laboratory and continued with analysis and description of data. Soil sampling wasconducted at distances of 250, 500, 750, 1.000, 1.250 and 1.500 meters from the Mentaya river bankat two depth soil layers (0 - 25 cm and 25 - 50 cm). The soil chemistry properties analyzed includedpH, cation exchange capacity (CEC), base saturation, organic C, N total, total P2O5, total K2O,alumunium and hydrogen exchangeable and soil fertility status. The results of study showed that: (1)The further distance of soil from the position of Mentaya river bank there is an increase of organic C,total P2O5, total N, total K2O, pH, CEC, base saturation and soil fertility status, on the contraryshowed a decrease in alumunium and hydrogen exchangeable. The limiting factor of soil fertility ismainly the low base saturation, besides that at some point observation also due to low CEC, totalP2O5 and total K2O. (2) Sub soil layer (25 - 50) cm has a higher pH and base saturation valuescompared to topsoil layer (0 - 25) cm. In contrast, topsoil layer has CEC, alumunium and hydrogenexchangeable, total P2O5, total K2O, total N and organic C values higher than sub soil layer.Keywords: distance from river, tidal soil, soil chemical properties.

Although natural and controlled fires are common in natural environments of the Province of Córdoba (Argentina), the effects on the physical and chemical soil properties are not well known. Warming effects were studied in two representative soil parent materials located in the piedmont of the Sierra Chica, Córdoba, Argentina. The aim of this study was to quantify the changes caused by different heating temperatures (100 °C and 500 °C), under laboratory conditions, on physical and chemical properties of two soils with different granulometric compositions and anthropic uses. The soils were classified as Udic Haplustoll, fine loamy (alluvial soils) and Udic Argiustoll, fine silty (loessoides soils). The depth analyzed corresponded to the upper 5 cm of the surface horizon. The physical property was granulometric composition (clay, silt and sand content) and the chemical properties: pH, oxidizable carbon (Cox), total nitrogen (Nt), cation exchange capacity (CEC), exchangeable cations (Ca<sup>+2</sup>, Mg<sup>+2</sup>, Na<sup>+</sup>, K<sup>+</sup>), extractable phosphorus (Pe) and electrical conductivity (EC). These analyses included both unheated samples (control) and those heated at different temperatures. Cox, pH, EC and CEC showed similar behavior at the different heating temperatures, despite the parent materials and the soil use conditions. Cox, pH, Nt and CEC could statistically explain the differences in edaphic properties at the temperatures analyzed. At 300 °C statistically significant differences were recorded for the analyzed soil parameters, and at 500 °C changes difficult to reverse due to the inorganic colloidal fraction collapse and the decrease (90%) of the organic fraction were found.

The aim of this study was to examine the effects of seasonal flooding on the properties of floodplain soils of Wukari Area of Taraba state. The treatments consisted of five different locations of Gidan-Idi, Gindin-Dorowa, Tsokundi, Rafin-Kada and Nwuko and three different soil sample depths of 0-20 cm, 20-40 cm, and 40-60 cm laid out in a completely randomized design (CRD) and replicated three times. Soil samples were collected from each plot in 2016 and 2017. All soil samples were analyzed for physical and chemical properties. The results obtained were subjected to analysis of variance and means separated using F-LSD test at p≤.05. The results of the soil properties analysis showed that some of the determined parameters were significantly different at the different sample locations at p≤.05. The soils of Wukari Floodplains are mostly clay loam in texture having very slightly acid to neutral soil reaction, moderate organic matter, low total N, moderate available P, low exchangeable bases and CEC. The flood plain soils were moderate in soil fertility, a confirmation of the general characteristic of Savanna soils. The soils were not deficient in micronutrients. Seasonal flooding had significant (positive) influence on some physical and chemical properties of the flood plains most particularly at Rafin-Kada.

Besides influenced by genotype, the quality and quantity of patchouli essential oil were controlled by soil as a growing medium. The development of patchouli plantation in Lamala District is still hampered by negative stigma from the community. It is believed, the strong absorption rate from patchouli could lead to soil nutrient deficiency. The purpose of this study was to determine soil fertility status and evaluate its suitability for patchouli plant in 3 land units (e.g., uncultivated, cultivated with fertilization, and cultivated without fertilization). The method used is an Exploratory-Descriptive Survey. The determination of soil properties was based on physical properties such as texture, and chemical properties such as pH, organic-C and nitrogen, P2O5 and K2O, base cations and cation exchange capacity/CEC, and Fe. The data then matched to Soil Fertility and Land Suitability Criteria for the patchouli plant. The result showed that the chemical properties in 3 land units had slightly acidic, high CEC, medium base saturation, moderate P2O5 content, and moderate organic-C content. Meanwhile, the K2O content of the land without patchouli was very low and the patchouli with and without fertilizer was low. Soil fertility status in 3 land units was classified as marginally suitable (S3-rc,na), this is due to the limiting factors; soil texture (rc) and P2O5 (na).

Abstract. As there are serious wellbore instability problems in Yitong area, studying sloughing mechanism and anti-sloughing measures of the strata is of great importance, which differs significantly from the previous researches. Based on the international state-of-the-art, in this work several points are focused on which include the appearance characteristics of the cores, rock mineral composition and the shale physical and chemical properties. Sloughing mechanism is classified and anti-sloughing measures of the strata in Yitong area are proposed. When testing shale physical and chemical properties, several parameters are mainly tested and analyzed, including cation exchange capacity, specific water absorption, shale recovery rate and shale inflation rate. Five core samples are selected and collated data is reflected in tables in the experiment. It is worth mentioning that a new method of specific water absorption is adopted in the study to explain wellbore instability problems, which are caused by hydration. Limitations and shortcomings have been overcome by specific water absorption instead of total water absorption when evaluating water sensibility. The test shows satisfying and excellent results. After applying the anti-sloughing measures to the strata in Yitong area, sloughing accidents have been alleviated.

The experiment was carried out to find out the impacts of plough pan on physical and chemical properties of soil. For this purpose, soil samples were collected from two locations of Basail upazila in Tangail dristrict, one having compact plough pan layer in subsoil (site-1) and other one with no plough pan layer (site-2). A survey was also conducted on land use pattern in these areas to get the causes of plough pan formation. In site-1, rice is the dominant crop and in site-2 shallow rooted crops such as mustard, potato, onion etc. are grown. In site-1, organic C, N, K, S, Zn contents were found higher and the concentrations of C, N, K, P, S and Zn decreased from topsoil to lower layers, whereas, concentrations increased to subsoil layer except P in case of site-2.   DOI: http://dx.doi.org/10.3329/jesnr.v5i1.11594   J.

ABSTRACT The intense anthropization in the lower São Francisco River and surrounding areas can lead to environmental degradation risks and, above all, makes the area more susceptible to soil erosion. This study aimed to identify and correlate the physical and chemical properties able to enhance erosive processes and slope instability in the watercourse margins of the lower São Francisco River, in Sergipe State, Brazil. To this end, disturbed and undisturbed samples of an Entisol-Fluvent soil were collected in the region, specifically in the city of Amparo de São Francisco. Physical (density, porosity, and texture) and chemical (pH, cation exchange capacity, base saturation, micro-, and macronutrients) analyses were performed. All physical properties and organic carbon contents were higher in the surface layers (Ap and AC) compared to the others. Organic carbon, phosphorus, and micronutrients had a negative correlation with soil density, showing higher contents and lower soil densities in the Ap and AC layers. The pedological characteristics of the evaluated soil layers are unable to provide soil resistance to water erosion.
