1. Winery distillery waste compost effect on the performance of melon crop under field conditions
ABSTRACT: The substantial generation of organic waste together with increasing interest in developing sustainable agriculture heralds an opportunity for mobilizing the recycling of these materials as a source of organic matter and nutrients into a viable management strategy option. A field experiment was conducted to evaluate the use of compost derived from

2. Plant senescence and proteolysis: two processes with one destiny
Abstract Senescence-associated proteolysis in plants is a complex and controlled process, essential for mobilization of nutrients from old or stressed tissues, mainly leaves, to growing or sink organs. Protein breakdown in senescing leaves involves many plastidial and nuclear proteases, regulators, different subcellular locations and dynamic protein traffic

3. Microbial Diversity: Relevance and Relationship Between Environmental Conservation And Human Health
This work presents bibliographic data on the role and function of microbial diversity. The increasing use of probiotics and prebiotics foods has led to the studies on their actual functions in the human body. It is known that in the environment, microorganisms are extremely important in recycling of nutrients, balance of trophic chains, vital physiological a

4. Algae of economic importance that accumulate cadmium and lead: a review
Currently, algae and algae products are extensively applied in the pharmaceutical, cosmetic and food industries. Algae are the main organisms that take up and store heavy metals. Therefore, the use of compounds derived from algae by the pharmaceutical industry should be closely monitored for possible contamination. The pollution generated by heavy metals rel

5. Dinâmica funcional da comunidade microbiana heterotrófica em lagoa rasa subtropical
Aquatic ecosystems float around trends in which abrupt transitions can occur between persistents regimes, alterning the viability of the resources or the physical and chemical parameters. Following this trend, communities vary in time and space as a result of their interactions with the environment and other organisms. Microbial communities are important com

6. Decomposition of Arachis pintoi and Hyparrhenia rufa litters in monoculture and intercropped systems under lowland soil.
Tropical grasslands under lowland soils are generally underutilized and the litter of forage legumes may be used to recover these degraded pastures. The objective of this work was to study the dynamics of litter decomposition of Arachis pintoi (pinto peanut), Hyparrhenia rufa (thatching grass) and a mixture of both species in a lowland soil. These treatments

7. Fertilidade do solo, nutrição e crescimento de plantas de eucalipto ao longo de 46 meses após aplicação de lodo de esgoto / Soil fertility, plant nutrition and growth of eucalyptus after 46 months of sewage sludge application
Objetivou-se avaliar o efeito da aplicação de lodo de esgoto, com ou sem adubo nitrogenado e, ou, fosfatado, sobre os atributos químicos do solo e o crescimento e nutrição de plantas de eucaliptos até aos 46 meses após aplicação do resíduo. Em dezembro de 2004 foi estabelecido um experimento de campo com quatro doses de lodo de esgoto (0; 7,7; 15,1

8. Deposition, chemical composition and decomposition of litter in a sabiá (Mimosa caesalpiniifolia Benth ) canopy / Deposição,composição química e decomposição de liteira em um bosque de sabiá (Mimosa caesalpiniifolia Benth) , Itambé-PE
The objective of this experiment was to evaluate the deposition, chemical composition, and decomposition of litter in a sabiá (Mimosa caesalpiniifolia Benth) canopy. The experiment was carried out at the Experimental Station of Itambé-IPA. The evaluation of existing and deposited litter was carried through the period of August of 2006 until July of 2007, e

9. Environmental impacts and nutrient recycling on pastures grazed by cattle
Grasslands are being replaced by urbanization and more profitable agricultural activities around the world. Producers may be faced with land constraints and need to consider intensification of the remaining grasslands as a means of maintaining overall production on a decreasing land resource. However, intensification of the grazing system is usually associat

10. Monitoramento do uso da terra e dos níveis de nutrientes do solo no Sistema Integrado de Produção Agroecológica utilizando geoprocessamento. / Monitoring of land use and soil nutrients levels on an integrated agroecological production system by image processing.
Agroecological production systems are more complex than conventional ones, since a series of crops follow in sequence or are intercropped to achieve high diversity and maximize soil nutrient recycling. The full understanding of these systems require systemic analyses and therefore, adequate tools. To understand soil fertility evolution, heterogeneity should

11. Estudos físico-químicos do efluente produzido por fossa séptica biodigestora e o impacto do seu uso no solo
The generation of effluent from the sewage treatment is daily increasing then its final disposition represents a mandatory question to be answered. An alternative is its agricultural utilization such as organic fertilizer as a partial substitute of mineral fertilizer. This practice, beyond inherent benefits due to nutrients recycling promotes agricultural wa

12. TRATAMENTO DE ÁGUA RESIDUÁRIA DOMÉSTICA E SUA UTILIZAÇÃO NA AGRICULTURA / TRATAMENTO DE ÁGUA RESIDUÁRIA DOMÉSTICA E SUA UTILIZAÇÃO NA AGRICULTURA / TRATAMENTO DE ÁGUA RESIDUÁRIA DOMÉSTICA E SUA UTILIZAÇÃO NA AGRICULTURA
O esgoto doméstico tratado quando disponibilizado para as atividades agrícolas proporciona economia de água de boa qualidade e fertilizantes químicos e incentiva às atividades agrícolas. Na região semi-árida do Brasil o reúso de água poderá ser uma alternativa para a convivência com a escassez dos recursos hídricos. Neste contexto, estão inseri
