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.

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).

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.

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.

Интенсификация земледелия в лесостепной зоне Среднего Поволжья требует решения проблемы сохранения почвенного покрова и его потенциального и эффективного плодородия с целью повышения урожайности сельскохозяйственных культур и качества растениеводческой продукции. В связи с этим разработка и внедрение в земледельческую практику агробиологических приемов предотвращения антропогенной деградации в агроландшафтах является актуальным направлением современной аграрной науки. Цель исследований заключалась в сравнительной оценке влияния навоза, сидератов и их сочетаний с биодеструктором стерни на физико-химические свойства лугово-черноземной почвы. Для достижения поставленной цели были проведены исследования в период с 2017 по 2019 гг. в первом агропочвенном районе Пензенской области. Исследованиями установлено, что действие и последействие навоза, сидератов и их комплексное действие и последействие с биодеструктором стерни оказало положительное влияние на физико-химические свойства лугово-черноземной почвы. Сидеральные пары по эффективности влияния на емкость катионного обмена, сумму обменных оснований, величину обменной и гидролитической кислотности не уступали унавоженным парам. Более существенное влияние на изменение физико-химических свойств почвы оказало комплексное действие и последействие навоза, редьки масличной и бобовых сидератов с биодеструктором стерни. Емкость катионного обмена на их фоне увеличилась на 1,40-1,51 мг-экв./100 г почвы, сумма обменных оснований на 1,6-1,7 мг-экв./100 г почвы, величина рНсолна 0,22-0,24 ед., величина гидролитической кислотности снизилась на 0,17-0,19 мг-экв./100 г почвы. Intensification of agriculture in the forest-steppe zone of the Middle Volga region requires solving the problem of preserving the soil and its potential and effective fertility in order to increase crop productivity and quality of crop production. In this regard, the development and implementation in agricultural practice of agrobiological techniques to prevent anthropogenic degradation in agricultural landscapes is an urgent direction of modern agricultural science. The purpose of the research was to compare the effect of the implementation of manure, green manure and their combinations with the stover biodestructor on the physical and chemical properties of meadow-chernozemic soil. To reach this purpose, research was conducted in the period from 2017 to 2019 in the first agro-soil district of the Penza region. Research has shown that the effect and after-effect of manure, green manure and their compound action and after-action with the stover biodestructor had a positive effect on the physical and chemical properties of meadow-chernozemic soil. Green manure fallows were not inferior to manured fallows in terms of their effect on the cation-exchange capacity, the sum of exchange bases, and the amount of exchange and hydrolytic acidity. A compound action and after-action of manure, the oil radish and green manure of legumes with the stover biodestructor had a more significant influence on the change in the physical and chemical properties of the soil. In their background, the cation-exchange capacity increased by 1.40-1.51 mg equivalent/100 g of soil, the sum of exchange bases by 1.6-1.7 mg equivalent/100 g of soil, the value of рНКСl 0.22-0.24 units, the value of hydrolytic acidity decreased by 0.17-0.19 mg equivalent/100 g of soil.

Soil Fertility Status

Abstract Plant growth requires nutrients and their functions in plants cannot be replaced by other elements so that if there are not enough nutrients in the soil, plants cannot grow normally. The nutrient content in the soil and the ability of the soil to provide nutrients for plant growth is different. So that the type of fertilizer and the amount of fertilizer given to each type of soil will be different and it depends on the type of plant being cultivated. To determine the requirements of fertilizers and the types of fertilizers required for each type of soil, need some research about the evaluation study of soil fertility. The research was conducted in Aceh Besar with located between 5¼ 2 ‘-5¼ 8’ N and 95¼ 80 ‘-95¼ 88’E. Assessment of soil fertility status based on the criteria of several soil chemical properties, CEC (cation exchange capacity), alkaline saturation, C-Organic, P2O5 (HCL, 25%) mg / 100g, and K2O (HCL, 25%) mg / 100g. The analysis results obtained from 11 sample points show that Aceh Besar has soil fertility status from medium to low.

Forest harvesting is a logging activity, distribution of trunks, skidding, loading and transportation. This activity involves a lot of heavy equipment that results in soil compaction and reduced vegetation cover. This condition causes changes in soil fertility conditions. This study aims to determine changes in soil fertility that occur due to forest exploitation activities. Namely by observing the physical and chemical properties of the soil in the area of the former skid trail, ex-TPn, former TPk, former logging areas. The research method used for data retrieval is the survey method with porposive sampling, while the data obtained is analyzed using descriptive analysis. Based on the results of the analysis of the physical and chemical properties of the soil, it shows that the former TPN area is the area with the lowest soil fertility value. Former logging areas have the best quality of soil fertility compared to other areas; such as former skid trails, former TPk and former Tpn areas even though they are still included in the low fertility classification, with organic matter in the former logged area of 2.24%. The organic matter content is only 0.8% with clay texture.Keyword: harvesting, forest, forest land, soil fertility
