Abstract
treatments which contained greater organic carbon, soil organic carbon stocks, and microbial biomass carbon, which results in a stable soil structure. The no-tillage system, which produced the maximum organic carbon and soil organic carbon stock among the tillage systems, showed the highest amounts of mean weight diameter (0.15 mm), and water-stable aggregates (92%). Our findings revealed that the high energy moisture characteristics method was highly sensitive to macroaggregate stability in water.

处理含有更多的有机碳、土壤有机碳储量和微生物生物量碳,从而形成稳定的土壤结构。在耕作系统中,免耕系统产生的有机碳和土壤有机碳储量最大,其平均重量直径(0.15mm)和水稳性团聚体的含量最高(92%)。我们的研究结果表明,高能水分特征法对大骨料在水中的稳定性高度敏感。K e y w o r d s:骨料消化、微生物活性、土壤管理、结构稳定性、Aridisols
期刊介绍:
The journal is focused on the soil-plant-atmosphere system. The journal publishes original research and review papers on any subject regarding soil, plant and atmosphere and the interface in between. Manuscripts on postharvest processing and quality of crops are also welcomed.
Particularly the journal is focused on the following areas:
implications of agricultural land use, soil management and climate change on production of biomass and renewable energy, soil structure, cycling of carbon, water, heat and nutrients, biota, greenhouse gases and environment,
soil-plant-atmosphere continuum and ways of its regulation to increase efficiency of water, energy and chemicals in agriculture,
postharvest management and processing of agricultural and horticultural products in relation to food quality and safety,
mathematical modeling of physical processes affecting environment quality, plant production and postharvest processing,
advances in sensors and communication devices to measure and collect information about physical conditions in agricultural and natural environments.
Papers accepted in the International Agrophysics should reveal substantial novelty and include thoughtful physical, biological and chemical interpretation and accurate description of the methods used.
All manuscripts are initially checked on topic suitability and linguistic quality.
