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...

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...

Population densities of the Mediterranean biotype of Tylenchulus semipenetrans were monitored in soil and citrus roots at 3-month intervals for 3 consecutive years in four citrus orchards in the provinces of Tarragona (Amposta and Xalamera) and Valencia (Moncada and Ca rcer). Nematode population densities in soil peaked once a year in April or July depending on the orchard and year. Numbers of ...

Coniferous seed orchards require a long period from initial seed harvest to stable seed production. Differential reproductive success and asynchrony are among the main factors for orchard crops year-to-year variation in terms of parental gametic contribution and ultimately the genetic gain. It is fundamental in both making predictions about the genetic composition of the seed crop and decisions...

This report describes the epidemiology, investigation and control of a hepatitis A (HAV) outbreak in New Zealand. Descriptive and analytical epidemiology, virology, product traceback and an orchard investigation were carried out. A case-control study revealed that 56% of 39 cases had consumed raw blueberries, compared with 14% of 71 controls (odds ratio 7.6; 95% confidence intervals 2.6-22.4). ...

The physiological and psychological relaxation effects of viewing a kiwifruit (Actinidia deliciosa 'Hayward') orchard landscape were investigated. Seventeen Japanese adult females (46.1 ± 8.2 years) viewed a kiwifruit orchard landscape or a building site (control) for 10 min. The heart rate variability and heart rate were determined. The modified semantic differential method and the short-form ...

We describe a natural way to plant cherryand plumtrees at prescribed generic locations in an orchard.

We describe and prove uniqueness of a natural homomorphism (called the Orchard morphism) between some groups associated to finite sets.
