The aim of this study was to establish the fractionation of copper and zinc in a small apple orchard using the revised (four-step) Bureau Communautaire de Référence (BCR) sequential extraction procedure and assess their potential mobility in soil. Soil samples were collected at the depth of 10 cm to 25 cm, sixteen from the orchard and five control samples from a meadow located some 200 m away f...

Plant parasitic nematodes (PPN) are known to survive periods of desiccation, an ability that increases the risk of them surviving unintentional transport between countries. To investigate nematode survival in soil subject to prolonged storage, soil collected from a native forest and an organic orchard was stored separately in cupboards at ambient temperature for 36 months. Subsamples were taken...

Soil aggregate stability is an important indicator for controlling soil losses and can improve soil quality, particularly in an area such as the Loess Plateau. The objective of this study was to estimate the differences in soil aggregates across six different land-use systems (grassland, apple orchard, abandoned apple orchard, cropland maize, cropland wheat, and shrub-grassland). For this purpo...

an orchard experiment was conducted at gonabad pistachio production station., khorasan, iran (1998-2003). in some pistachio trees, especially in cv. owhadi, leaf marginal chlorosis was already observed. then, gradual drying of leaves extended to the leaves' centers up to midsummer. with respect to salinity problems, some researches were done. two orchards of pistachio known as no.6 and no....

The Biodiversity Support Program (BSP) was established in 1988 with funding from the Research and Development Bureau of the U.S. Agency for International Development (USAID), under cooperative agreement number DHR-5554-A-00-8044-00. BSP is implemented by a consortium of World Wildlife Fund, The Nature Conservancy, and the World Resources Institute. The central purpose of the program is to suppo...

The influence that different styles of olive-orchard management (conventional, integrated, and organic) exert on the predator Chrysoperla carnea has been studied to strengthen this insect's role in the integrated management against pests. For this, the adult chrysopid populations were determined by McPhail traps, and laboratory examinations were made of certain biological characteristics of the...

BACKGROUND The increasing trend in the incidence of primary malignant brain tumors in orchard farmers and their families in Kashmir. AIM To determine the relationship between the patients of primary malignant brain tumors and their occupation. MATERIALS AND METHODS Retrospectively, case files along with death certificates of 432 patients of primary malignant brain tumors and 457 controls (n...

Respected on both sides of the Atlantic for questioning the tenets underlying the pathophysiology of diabetes and its complications, Trevor Orchard continues to influence the fields of epidemiology and medicine. With a self-effacing style that might be described as typically British, he remains provocative and prominent among the research community. An Englishman educated in Wales and living in...

In this paper,it gave a detailed introduction about the classification process of land use in Guangzhou supported by RS and GIS software using the data of Landsat TM of 1997 and 2003. After being geometric corrected subset and enhanced, the images were classified into 9 classes as farmland, orchard, forest, disk-pond, urban and rural land, developing area, river, lake and unused land by using m...

Seasonal population of the fruit-piercing moths Eudocima spp. was monitored throughout the citrus growing seasons in a citrus orchard and in site adjacent to secondary forest from July 2007 to June 2009. The moth was detected practically throughout the year with activity lowest during the wet months (September-February) when fruits are still available and while highest during the dry months (Ma...
