ABSTRACT: It is estimated that by 2050 the world population will be 9 billion people; and therefore, need for alternative sources of protein inevitable, since conventional sources, such as beef, pork poultry, not sufficient to meet demand growth. Food includes protein, insects, a reality in countries Latin America, Asia, Australia, Europe Africa. This research presents results an exploratory study analysed food profile 1,619 consumers five Brazilian regions (North, Northeast, Midwest,...
The diverse biological activities attributed to essential oils (EOs) mean that the market for these products is on rise. Today it known several factors influence quantity and quality of secondary metabolites, is, their production responds variably biotic abiotic factors, including seasonality. In order understand effects seasonality EO yield, ten aromatic species were studied over two years, with repeated collections in four different seasons. results presented here show yield varied...
Vermicomposting has been found as a profitable approach to dispose of and treat large quantities raw grape marc. However, less information is available with regard its efficiency for treating distillery winery byproducts, even though distillation widely used way economically valorize As such, we sought characterize the compositional functional changes in bacterial communities during vermicomposting distilled marc by using 16S rRNA high-throughput sequencing. Samples were collected at...
ABSTRACT: Composting and vermicomposting before addition to the soil is a viable alternative disposal of cattle manure. However, this residue has been used in untreated form for seedling production. This study evaluated use manure natura, organic composted or vermicomposted variants on substrates production Eucalyptus urograndis seedlings. The treatments consisted formulated by mixing fertilizers with washed sand 20, 40, 60, 80 100 (v/v) percentages, compared commercial substrate. E....
The efficiency index (EI) refers to the ratio of nutrients mineralized/made available in soil total amount added by organic fertilizer. Therefore, understanding EI is essential for recommendation fertilization. aim this study was evaluate availability through mineralization and nitrogen (N), phosphorus (P), potassium (K) fertilizers produced from cattle manure. following treatments were evaluated an incubation experiment under controlled conditions: without fertilizer (control); + beef...
Wildfire events cause considerable environmental disturbance but few studies have examined changes in soil properties due to fire. This study aimed assess the effect of a wildfire event on chemical, physical, and biological eucalyptus forest Pampa biome. Part seven-year-old was affected by that lasted for two days. Soil plant litter sampling performed three areas: not fire, it, an adjacent natural pasture area (the original vegetation). Seven samples were collected from 0.00-0.05 0.05-0.20 m...
ABSTRACT: Phytoremediation is an alternative technique used to treat copper-contaminated soils. The objective of this research was explore the behavior nine summer cover crops regarding growth, absorption and translocation copper in soils with contamination levels exceeding Value Prevention, a view selecting plants for phytoremediation programs. In experiments Cambisol contaminated copper, added doses 0, 100, 200, 400, 500 600mg kg-1, which following were cultivated under greenhouse...
ABSTRACT: The successive application of pig slurry to pastures is a common practice in southern Brazil, serving as method waste disposal well an important alternative chemical fertilization. Although there are economic benefits the use manure fertilizer, it may be associated with environmental hazards and cause changes composition activity soil fauna. This study aimed effects on biota pastures. Composition biological where was applied successively for 2 years (A2) 14 (A14) were evaluated,...
Objetivou-se avaliar o efeito de diferentes usos do solo na abundância, riqueza, diversidade e atividade organismos da fauna edáfica. A foi amostrada em: florestamento Eucalyptus spp., Pinus lavoura grãos, impactado pela construção civil pastagem natural. Para a avaliação dos epiedáfica empregou-se método armadilha queda para amostragem hemiedáfica utilizou-se TSBF. biológica avaliada pelo lâminas bait. Foram coletados 5.413 epiedáficos 813 hemiedáficos, distribuídos em 18 grupos...
An alternative to controlling weeds resistant conventional herbicides is the isolation of new active principles. Fungi can produce phytotoxic metabolites that may be used in development herbicides. The objectives this study were: (1) isolate, select, and identify a fungus producer (2) optimize culture conditions low-cost medium, with aim increasing effects their commercial plants. were isolated from leaves Conyza sp. disease symptoms selected according production solid submerged fermentation...
This work aimed to characterize the composition of soil macrofauna in non-mined and mined areas recovered with native vegetation, Eucalyptus dunnii Maiden Acacia mearnsii De Wild. plantations, a coal mine. Five were evaluated, namely, three two areas. Six samples per area collected using 10x10 cm circular probe, every month during one year. Defragmentation removal specimens was carried out laboratory. A total 3,195 from 11 taxa collected. The most abundant groups Hymenoptera, Isoptera...
O trabalho teve por objetivo avaliar a produção de alface (Lactuca sativa L., var. Ceres), partir fertilizantes produzidos à base esterco bovino. experimento foi conduzido em duas etapas, mudas e plantas, casa vegetação. Na foram avaliados os fertilizantes: bovino (EB); vermicomposto (VEB); composto produzido palha (CEBP); o substrato comercial (SC), nas dosagens 20, 40, 60, 80 100% (v/v). plantas utilizados EB, VEB, CEBP, adubação mineral (MIN), doses 33, 66, 100, 133 166% nitrogênio...
Copper (Cu) mining have been carried out for more than a century in the Minas do Camaquã region, southern Brazil. Currently, this site has an extensive area impacted by disposal of tailings and soil high levels Cu. As result contamination, little or no vegetation cover, increasing risk other environmental compartments being affected. Phytoremediation can be used to mitigate problem, its efficiency enhanced use organic amendments. Therefore, study sought evaluate effect sewage...
