A review of organic growers' concerns about weeds is presented and several issues that may ease those concerns are highlighted. The underlying principles of organic weed management (OWM) are briefly discussed and results from organic grower surveys regarding weed management practices in organic horticultural cropping are presented. The most common weeds encountered by organic growers, often tho...

II. The Foundations of Organic Chemistry A. The branch of chemistry specializing in the study of carbon compounds. 1. Organic molecules are molecules containing carbon. 2. Called organic molecules because these compounds were only found in living beings. 3. Vitalism a. Belief in a life force outside the jurisdiction of chemical/physical laws. b. Organic chemistry in early 19th century was built...

background and objectives:anionic polyacrylamide application as an organic conditioner alone or in combination with organic material, can improve soil properties. the objective of this study was to investigate the influence some organic conditioners on mean weight diameter (mwd) and dispersible clay percentage (dcp).materials and methods:soil samples collected from the top 30-cm layer of two lo...

Burgeoning consumer interest in organically grown foods has opened new market opportunities for producers and is leading to a transformation in the organic foods industry. Once a niche product sold in a limited number of retail outlets, organic foods are currently sold in a wide variety of venues including farmers markets, natural product supermarkets, conventional supermarkets, and club stores...

Based on China’s organic paddy rice farmers’ data collected from field surveys in Wuchang City, this paper utilises a data envelopment analysis method to estimate the technical efficiency scores of organic paddy rice farmers converting from conventional to organic production. Local organic rice-processing firms provide support to farmers to convert to organic production and, thereby, expand the...

The investigation of charge transport in organic nanocrystals is essential to understand nanoscale physical properties of organic systems and the development of novel organic nanodevices. In this work, we fabricate organic nanocrystal diodes contacted by rolled-up robust nanomembranes. The organic nanocrystals consist of vanadyl phthalocyanine and copper hexadecafluorophthalocyanine heterojunct...
