this study was conducted to investigate the impact of land use change on some of carbon components in safashahr area, fars province. four land uses (destroyed rangeland, agricultural land, new and old apple orchard) were selected. sampling was done randomly from two depths (0-20 and 20-50 cm) of each land use. particulate organic matter (pom) and extractable carbohydrate by hot water were measu...

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...

In this study influence of land-use type on soil respiration was investigated in poplar plantation, apple orchard (apple trees with understory grasses) and adjacent grassland sites in Seyitler Area, Artvin, Turkey. Soil respiration was measured approximately monthly in three sampling plots in each land use type from January 2005 to November 2005 using the soda-lime technique. Mean daily soil re...

Scattered trees support high levels of farmland biodiversity and ecosystem services in agricultural landscapes, but they are threatened by agricultural intensification, urbanization, and land abandonment. This study aimed to map and quantify the decline of orchard meadows (scattered fruit trees of high nature conservation value) for a region in Southwestern Germany for the 1968 2009 period and ...

the purpose of this research was to analyze the impact of agronomic land use change to orchard in the west of urmia lake basin. the target population was about 12000 consisting of all the farmers in the west of urmia lake basin that changed their agronomic land use to orchard. using cochran’s formula and stratified random sampling method, 150 apple and grape growers were chosen. required data w...

Landscapes of farms and adjacent areas are known to influence abundance of various arthropods such as pollinators in commercial agricultural ecosystems. In this context, we examined the effect of heterogeneous landscapes surrounding and including commercial apple orchards on pollinator visitation and foraging distance during bloom period from 2011 to 2013 in Pennsylvania. Our results showed tha...

Comprehensive Automation for Specialty Crops (CASC) is a four-year project to develop crop intelligence and agricultural automation technologies for the apple and nursery tree industries. Supported by the USDA Specialty Crop Research Initiative, CASC aims at impacting industry where it matters most: increasing production efficiency and reducing labor costs. In this paper we present our most rec...
