This paper briefly introduces the main ideas of Machine Translation (MT) techniques,then discusses the application of MT in the ChinaAmerica Digital Academic Library (CADAL)
effects of different soil moisture regimes and p application on available and inorganic p forms were studied in four paddy soils, north of iran. a factorial experiment in a completely randomized design with two replications was performed in a laboratory study. factors of soil at four levels (two acid and two alkaline-calcareous soils), soil moisture contents at three different levels (air-dry, ...
This study investigated the occurrence and dissipation of three azole biocides climbazole, clotrimazole and miconazole in biosolid-amended soils of the three sites (Zhejiang, Hunan and Shandong) in China following three treatments (CK: control without biosolid application; T1: one biosolid application; T2: biosolid application every year). The results showed that climbazole, clotrimazole and mi...
Sodic soil is one of the most common problems of limiting agricultural production that related on irrigation. Saturated hydraulic conductivity is one of hydrodynamic characteristics in evaluating transmission flow through underground levels. To investigate the role of increment of exchangeable sodium in hydraulic conductivity changes (as characterized by the mobility of water in soil) an experi...
Revegetation of saline–sodic soils is challenging. Over 10 million hectares are intertwined with highly productive in the Northern Great Plains, 3.4 ha South Dakota. Establishing salt-tolerant perennial plants provides soil cover and remediates barren areas. Two grass mixes [Mix 1: slender wheatgrass (Elymus trachycaulus [Link] Gould ex Shinners) + beardless wildrye (Leymus triticoides [Buckley...
Rising temperatures and elevated atmospheric CO2 are two factors that simultaneously affect the dynamics of soil organic carbon (SOC). This study separately examines the effects arise from these two factors in Tai-Lake Paddy soils using DeNitrification–DeComposition (DNDC) model, with the currently most detailed soil database for the paddy region of China. The soil database is at a scale of 1:5...
