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.

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.

The large distribution of peat soils in Indonesia have important role in carbon stock and greenhouse gas emission which contribute to global warming issue. The objective of this study was to characterize physical and chemical properties of cultivated peat soils in four trial sites of Indonesia Climate Change Trust Fund (ICCTF) in Central Kalimantan, South Kalimantan, Riau and Jambi Provinces to provide a baseline data by a greenhouse gas emission study. Detailed soil observations were conducted using grid system with spacing of 25 × 50 m. A total of 16 representative peat soil profiles consisting of 74 soil samples of horizons were selected for laboratory analyses. The results showed that peat maturity varied from hemic to sapric in the surface layers and hemic in the subsurface layers, except in Site-2 that was fibric. The peat thickness ranged respectively from 5.4 to 7.0 m in Site-1 and Site-3, and from 0.5 to 2.5 m in site-2 and site-4, and all overlying fine-textured mineral soil (substratum). Depth of water table varied from 10 to 30 cm in Site-2 and Site-4, and from 30 to 70 cm in Site-1 and Site-3. Fiber content ranged from 13 to 57% and increased with depth indicating the peat was less decomposed. The bulk density was very low (0.07-0.24 g cm-3) and negatively correlated to fiber content (r = 0.74 for Kalimantan and r = 0.66 for Sumatra). The ash content was low (0.1-8.5%) and negatively correlated to organic carbon content (r = 0.89 for Kalimantan and r = 0.65 for Sumatra). Soil CEC was high and positively correlated to organic carbon content (r = 0.86 for Kalimantan and r = 0.93 for Sumatra). These soils showed very acid reaction (pH 3.3-4.7), low content of exchangeable bases and total P2O5 and K2O (HCl 25%). Based on these properties, the peat soils were grouped as oligotrophic ombrogenous peat. The estimated carbon stock for all the trial sites with total extent of 22.58 ha was 57,282 Mg C. The variation of thickness, maturity, and water table depth will imply to the magnitude of carbon reserves and greenhouse gas emissions. [How to Cite: Hikmatullah and Sukarman. 2014.

Four typical pedons representing major mango growing soils, developed from granite gneiss parent material were studied for their morphological, physical and chemical properties. The soils were moderately shallow (50-75 cm) to very deep (>150 cm) in depth, loamy sand to sandy clay loam in texture, sub-angular blocky in structure, reddish brown to dark red in colour, slightly acidic to moderately alkaline in reaction, non-saline, very low to high in organic carbon content (0.09 to 1.29%), low AWC (3.36 to 7.80%), low to medium in cation exchange capacity (2.90 to 19.36 cmol (p+) kg-1) and high base saturation (78 to 98%). The soils also had high amounts of coarse fragments in P1 and P2 and high clay content in P4 and P2. Among the exchangeable cations, calcium was found to be high in most of the soils, followed by magnesium, sodium, and potassium. Based on the soil characteristics, the mango growing soils were classified as Typic Haplargids and Typic Paleargids in subgroup level. Varying soil and site characters i.e., poor rainfall, shallow soil depths, excess gravel contents, low AWC, poor nutrient status and severe soil erosion are limiting the growth and development of mango plantation. Developing site-specific soils based suitable management practices can improve the productivity of mango crops.
