Provedor de dados: 90
Autores: Abbruzzini,Thalita Fernanda; Silva,Carlos Alberto; Andrade,Daniela Aparecida de; Carneiro,Waldete Japiassú de Oliveira.
There are currently many devices and techniques to quantify trace elements (TEs) in various matrices, but their efficacy is dependent on the digestion methods (DMs) employed in the opening of such matrices which, although "organic", present inorganic components which are difficult to solubilize. This study was carried out to evaluate the recovery of Fe, Zn, Cr, Ni, Cd and Pb contents in samples of composts and cattle, horse, chicken, quail, and swine manures, as well as in sewage sludges and peat. The DMs employed were acid digestion in microwaves with HNO3 (EPA 3051A); nitric-perchloric digestion with HNO3 + HClO4 in a digestion block (NP); dry ashing in a muffle furnace and solubilization of residual ash in nitric acid (MDA); digestion by using aqua...

Provedor de dados: 123
Autores: Mayorga,David Andrés Camargo; García,Octavio Cardona; Guzmán,Juan Manuel González.
Resumen: Este artículo tiene como objetivo estimar una función de producción de compost para 31 países de Europa usando la metodología de panel de datos. La motivación del documento se basó en el rezago que existe en la literatura económica, sobre temas relacionados con el tratamiento de residuos sólidos y su posible reintegración al mercado. Se encontró que la función de producción que mejor se ajusta es la translogarítmica. Al calcular las elasticidades de sustitución de Allen se halló que el capital, representado por el índice de instalación de nuevas plantas de tratamiento, es complementario con los demás factores de producción. Caso contrario ocurrió con el trabajo y los residuos municipales generados, siendo sustitutivos para el grupo de países...

PHOSPHORUS IN ORGANIC WASTE-SOIL SYSTEMS
Provedor de dados: 127
Autores: Fuentes,Bárbara; Bolan,Nanthi; Naidu,Ravi; Mora,María de la Luz.
Increases in the generation of organic wastes, in addition to decreases in natural resources, make it necessary to recycle these waste materials. In soils, the application of wastes as organic fertilizers, allows to reincorporate nutrients to the biogeochemical cycles. The application of wastes in agriculture has carried out with it problems associated with phosphorus (P) overapplication in soils and contamination of water bodies. Phosphorus inside the waste matrix forms organic and inorganic compounds which have different bioavailabilities. The more important factors that influence the bioavailability of P in soils, organic wastes and soil-organic waste amendments are: the soil solution pH, adsorption reactions, organic matter, phosphatase activity and...

Provedor de dados: 111
Autores: Park, Kyu-Hyun; Ngwabie, Ngwa Martin; Wagner-Riddle, Claudia.
Composting has the potential to mitigate methane (CH4) and nitrous oxide (N2O) emissions from manure.  The heterogeneous nature of emitting surfaces makes it difficult to quantify these emissions.  CH4 and N2O fluxes measured using eight small chambers (0.72 m2) and a mega chamber (90 m2) were compared, and the effect of aeration on the fluxes during composting was studied.  Two batches of compost were placed in three channels and 2-3 small flux chambers were deployed on each channel.  The channels were enclosed by a building serving as a mega chamber.  Chamber location significantly affected gas fluxes, pointing to strong spatial heterogeneity.  Mean CH4 fluxes from the small chambers were similar or 1.4 times higher compared to the mega chamber.  Mean...

Organic Versus Conventional Methods of Fertilization and Weed Control in a Long Term Rotation of Cereals in Semiarid Spain
Provedor de dados: 117
Autores: Pardo,Gabriel; Aibar,Joaquín; Ciria,Pilar; Lacasta,Carlos; Lezaún,Juan Antonio; Zaragoza,Carlos.
Under semiarid conditions the response of cereal crops to chemical fertilizers and weed control practices with herbicides is often reduced. In fact, the economic profitability of agricultural production in many dryland regions is critically affected by high costs of inputs and low crop yields. As a solution, cropping systems like organic farming, obtaining similar yields and promoting environmental sustainability by reducing fertilizer and herbicides, could be an alternative to conventional systems. In this study, 23 trials were performed in five semiarid regions of Spain during 5 yr to compare different fertilizers and weed control methods on durum wheat (Triticum durum Desf.) and barley (Hordeum vulgare L.) yields. The following rotation pattern was...
