1. Management of rice straw in rice-soybean succession in tropical lowland
ABSTRACT This study aimed to analyze rice straw alternative managements to maximize the rice-soybean succession yield and to quantify their impacts on soil properties. The experiment was set up in a completely randomized design with six replicates. Nine rice straw managements were evaluated: straw burning (M1), straw harvesting (M2), straw incorporation with

2. Enzymatic efficiency of the decomposing microbiota: what does really matter for aquatic macrophytes invasions?
ABSTRACT Biological invasions have negative impacts on different ecosystem-level functions, such as nutrient cycling. In aquatic environments, exotic litter can change the activity of the decomposer microbiota. We tested whether litter quality, litter decay, and enzyme activity differed between nativeEgeria densaand exoticHydrilla verticillata. The invasive

3. Prediction of quality parameters of food residues using NIR spectroscopy and PLS models based on proximate analysis
Abstract The real-time prediction in biorefinery industries has become essential. Models using partial least square regression (PLS) were developed to predict moisture, ash, volatile matter, fixed carbon and organic matter of coconut and coffee residues. In this study, 49 samples were collected and near infrared spectroscopy were applied to predict moisture,

4. Seasonal performance of aquatic macrophytes in improving physicochemical parameters of swine wastewater
Resumo Os efluentes da suinocultura apresentam elevado teor de carga orgânica e de nutrientes, o que dificulta o seu tratamento. Dessa forma, as macrófitas aquáticas representam uma alternativa para a despoluição desses efluentes, devido ao alto poder de absorção que essas plantas possuem. Neste contexto, o objetivo deste estudo foi avaliar o desempen

6. Fermentation characteristics and in vitro ruminal digestion of yacon residue silage with lactic acid bacteria inoculant or beet pulp
ABSTRACT In this study, we examined the effects of lactic acid bacteria (LAB) inoculant and beet pulp (BP) on the quality of yacon (Smallanthus sonchifolius) residue silage. Yacon silage was prepared using a small-scale system of silage fermentation, and the treatments were as follows: control silage without any additive and silages with LAB inoculant Chikus

7. Methods and rates of poultry litter fertilization for corn silage in organic system
ABSTRACT. The creation of proper soil fertility is fundamental to the agroecological transition phase and guarantees the sustainability of organic agribusiness. In a randomized complete block design with a 3 x 2 factorial scheme with 1 additional treatment (control, without organic fertilizer), we tested three poultry litter rates (7, 14, and 21 Mg ha-1) at

8. Methodology for minimum nitrogen compounds removal efficiencies estimation and wastewater treatment systems pre-selection: a watershed approach
RESUMO O nitrogênio constitui importante parâmetro para o controle da poluição hídrica, uma vez que a nitrificação produz consumo de oxigênio do ambiente aquático, além da toxicidade associada à algumas formas de nitrogênio. Este estudo estabeleceu e empregou modelo de otimização visando a determinação simultânea de eficiências mínimas de

9. CHANGES IN THE SOIL STRUCTURE AND ORGANIC MATTER DYNAMICS UNDER DIFFERENT PLANT COVERS
ABSTRACT The soil properties reported in areas with different management provide useful information about the systems’ operation, state of conservation and resilience. In this way, this study evaluated physical properties and organic matter dynamics of soil under different plant covers in seven areas consisting of: five areas under ecological restoration (

10. Yield and quality of seeds of lettuce genotypes produced under organic management
Resumo: A alface é uma das principais espécies de hortaliças utilizadas na produção orgânica, porém, os estudos e pesquisas na área de orgânicos são considerados escassos. O objetivo do estudo foi avaliar a produtividade e qualidade de sementes de genótipos de alface produzidas em dois anos consecutivos no sistema de manejo orgânico. Foram instal

11. Impact and management of diseases in the propagation of fruit plants
Resumo Mudas bem formadas e sadias são o sucesso econômico na fruticultura. A sanidade das mudas deve ser assegurada durante o processo de produção, evitando a morte de plantas e a disseminação de patógenos para novas áreas, tendo como consequência o aumento do custo de produção e a redução da produtividade, podendo determinados patógenos, inv

12. PEDOFUNCTIONS APPLIED TO THE LEAST LIMITING WATER RANGE TO ESTIMATE SOIL WATER CONTENT AT SPECIFIC POTENTIALS
ABSTRACT The least limiting water range (LLWR) is a soil physical quality indicator that receives much attention. It has been criticized and put to the test regarding mathematical models that compose it since they describe the behavior of soil physical attributes in a simplified way. This study aimed to assess the efficiency of some pedofunctions proposed in
