Fungal diversity in the soil may be limited under natural conditions by inappropriate environmental factors such as: nutrient resources, biotic and abiotic factors, tillage system and microbial interactions that prevent the occurrence or survival of the species in the environment. The aim of this paper was to determine fungal genetic diversity and community level physiological profiling of micr...

To determine the optimal ploughing depth and to make tillage simpler and less costly, but also taking account of edaphic and climatic conditions as well as biological and agrotechnical requirements of crops grown, long-term investigations (1994-2009) have been carried out on Stagnic Luvisol of sloping terrains in central Croatia near Daruvar. Th e paper presents the results relating to plant de...

Soil nitrogen cycling microbial communities and functional gene α−diversity indicate soil ecological functions potentials. Crop rotation plans affect fractions these indicators. We sequenced samples from four crop (fallow, winter wheat monoculture, pea-winter wheat-winter wheat-millet rotation, corn-wheat-wheat-millet rotation) in a long-term field experiment. examined how changed with regulate...

We simulated the effects of irrigation on groundwater flow dynamics in the North China Plain by coupling the NIES Integrated Catchment-based Ecohydrology (NICE) model with DSSAT-wheat and DSSAT-maize, two agricultural models. This combined model (NICE-AGR) was applied to the Hai River catchment and the lower reach of the Yellow River (530 km wide by 840 km long) at a resolution of 5 km. It repr...

Buried archeological features show up as crop marks that are mostly visible using high-resolution image data. Such data are costly and restricted to small regions and time domains. However, a time series of freely available medium resolution imagery can be employed to detect crop growth changes to reveal subtle surface marks in large areas. This paper aims to study the classical Chinese settlem...

Through the website of International Water Management Institute, the referenced evapotranspiration (ET0) was found which was calculated by the meteorological data during 1961-1999 from 147 stations in Sichuan Province. Further, according to the crop coefficients of rice, maize, wheat, rape, the water requirements (ET) of main crops were estimated by using Food and Agriculture Organization (FAO)...

Soil degradation and high environmental costs impede agricultural production in North China. A 6-year field experiment was conducted to determine the effects of tillage practice nitrogen application rate on changes soil fertility wheat yield. Four systems (rotary without maize straw return through 6 years, RT; rotary with RS; deep DS; 2 years followed by next year applied for two cycles, RS/DS)...

A potted experiment was conducted to explore the accumulation of arsenic (As) and predict uptake As by a wheat-maize rotation system in calcareous soil with different rates sewage sludge (SS) amendment over two consecutive years. The SS decreased pH value but increased cation exchange capacity (CEC), calcium carbonate (CC), organic carbon (OC) crops increasing addition. bioconcentration factor ...

The production and consumption of the greenhouse gases (GHGs) methane (CH4), carbon dioxide (CO2) and nitrous oxide (N2O) in soil profile are poorly understood. This work sought to quantify the GHG production and consumption at seven depths (0-30, 30-60, 60-90, 90-150, 150-200, 200-250 and 250-300 cm) in a long-term field experiment with a winter wheat-summer maize rotation system, and four N a...
