Air pollution is a critical environmental issue for California, which has some of the nation’s most polluted air basins and also the nation’s most stringent set of state and local air quality standards. This paper reviews my previous work in Lin (2011), in which I examine the effects of agriculture-related local regulations in California on air quality, as measured by the number of exceedances ...

We study the Orchard relation defined in [3] for generic configurations of points in the plane (also called order types). We introduce infinitesimally-close points and analyse the relation of this notion with the Orchard relation. The second part of the paper deals with monochromatic configurations (for the Orchard relation). We give the complete list of all monochromatic configurations up to 7...

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...

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....

Abstract Bangkok’s Inner Orchard (BIO), located in the west peri-urban area of city, provides both fresh products and ecological benefits to its inhabitants. Although this unique forest-like cultivation mixed fruit trees growing on dikes has potential become an urban forest, it never been thoroughly investigated. Urban expansion is a threat orchard. Sustainable cities must maintain balance betw...

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...

Habitat fragmentation can change the community composition of species in remnant habitat patches. We studied the impacts of fragmentation by agriculture on the bird community in heavily fragmented areas of the sagebrush shrubsteppe in western North America. We examined whether bird communities in sagebrush habitat near orchards and vineyards were different from the community in interior sagebru...
