*Galina N. Koptsik and Svetlana Yu. Livantsova, Soil Science Faculty, Moscow State University, Moscow 119899, Russia; Serguei V. Koptsik, Faculty of Physics, Moscow State University, Moscow 119899, Russia. *Corresponding author: [email protected] ABSTRACT Soil conservation has fundamental significance for biodiversity conservation and sustainable land use. Variations in soil types within the ...
Hardpans (plough/hoe pans) are commonly believed to restrict plant root growth and crop yields under conventional small-scale agriculture in sub-Saharan Africa. This study questions the notion of widespread hardpans in Zambia and their remedy under conservation tillage. Soil penetration resistance was measured in 8x12 grids, covering 80 cm wide and 60 cm deep profiles in 32 soil pits. Large and...
Soil degradation is one of the most topical environmental threats. A number processes causing soil degradation, specifically erosion, compaction, salinization, pollution, and loss both organic matter biodiversity, are also strictly connected to agricultural activity its intensification. The development adoption sustainable agronomic practices able preserve enhance physical, chemical, biological...
The USDA Natural Resources Conservation Service State Soil Geographic (STATSGO) database contains general soils information, but data available in STATSGO cannot be readily extracted nor parameterized to support regional environmental quality modeling. As such, each user must individually and repeatedly process data in STATSGO to obtain necessary soil properties. The objective of this study was...
Prioritization of critical sub-watershed is an important procedure to control runoff and erosion phenomenon and considered as effective way in management of watersheds and achieving sustainable development. The main aim of this study is assessing the soil erosion-prone areas and prioritization of 30 hydrologic response unit of Rozehchai Watershed that located in West Azerbaijan province (186.41...
Quantitation and evaluation of infiltration models are used in soil conservation, irrigation systems, hydrology investigations, watershed and watershed management systems. The purpose of this study was to estimate the infiltration by using statistical and experimental various models in two soils of plowed and without plowed in Haraz Technology and Development center paddy fields of Mazandaran p...
Quantifying crop residue cover on the soil surface is important for improving estimates of surface energy balance, net primary productivity, nutrient cycling, and carbon sequestration. Quantifying crop residue cover is also an important factor in controlling soil erosion and evaluating the effectiveness of conservation tillage practices. By reducing the movement of eroded soil into streams and ...
