1. Least limiting water range in Oxisol under two conservation tillage systems in sugarcane farming
ABSTRACT The Least Limiting Water Range (LLWR) is an indicator of soil physical quality, contributing in information to propose soil management systems in agricultural farming process. This work aimed to assess the usage of LLWR and critical soil bulk density for physical-water quality evaluations, as well as its effect on sugarcane farming under no-tillage

2. Carbon and Nitrogen Stocks Under Different Land-Use in the Paraopeba River Basin-MG Before the Corrégo do Feijão Dam Burst
ABSTRACT Soil attributes can provide indicators for the management and conservation of natural and agrarian ecosystems. This study was carried out before the rupture of the Córrego do Feijão dam and aimed to evaluate and quantify the stocks of carbon, nitrogen and the C/N ratio in soils around the Paraopeba-MG river basin in five regions corresponding to t

3. Effects of different legume green manures on tropical soil microbiology after corn harvest
ABSTRACT Legume green manure is a popular practice for sustainable agriculture in tropical environments. The use of grain, forage and purely green manure legumes in a subhumid tropical area in Northeast Brazil was investigated to determine the total C and N contents and estimate C-microbial biomass, soil basal respiration, microbial and metabolic quotients,

4. Post-laser in situ keratomileusis interface Arthrographis kalrae keratitis
RESUMO Descrevemos um caso de ceratomicose por Arthographis kalrae após ceratomileusis por excimer laser. Uma mulher de 38 anos desenvolveu ceratite estromal oito semanas após a cirurgia refrativa. Ela desenvolveu infiltração estromal grave da córnea e uma leve inflamação do segmento anterior, que não pode ser tratada com voriconazol tópico a 1%, ma

5. Phosphate Sources and Filter Cake Amendment Affecting Sugarcane Yield and Soil Phosphorus Fractions
ABSTRACT: The use of mineral phosphate fertilizers associated with organic residues can improve fertilizer use efficiency and consequently decrease their usage costs. Soil application of filter cake (FC) can provide nutrients and enhance physical quality. This study aimed to evaluate the effects of different phosphate fertilizers [rock phosphate (RP) and tri

6. Determination of the spatial susceptibility to Yellow Fever using a multicriteria analysis
BACKGROUND The outbreak of sylvatic Yellow Fever (SYF) in humans during 2016-2017 in Brazil is one of the greatest in the history of the disease. The occurrence of the disease in areas with low vaccination coverage favoured the dissemination of the disease; therefore, it is necessary to identify the areas vulnerability to the YF virus (YFV) to assist in th

7. Effect of previous soil management on sugarcane response to nitrogen fertilization
ABSTRACT: N Fertilizer recommendations must be improved to optimize N use efficiency (NUE) for bioenergy crops. A study was conducted to test the hypothesis that sites varying in historical usage of by-product differ in soil N-supplying power and sugarcane (Saccharum spp.) responsiveness to N fertilization. Our aim was to quantify soil N availability and N f

8. Agronomic performance of green cane fertilized with ammonium sulfate in a coastal tableland soil
ABSTRACT The recent approach of eliminating the usage of fire for sugarcane harvesting resulted in managing the crop on a trashblanketed soil, to which a proper recommendation of N fertilization is lacking, a problem that remains in the coastal tablelands of the Espírito Santo State, Brazil. This study aimed at evaluating the effect of increasing N rates on

9. Carbon and Nitrogen Stocks and Humic Fractions in Brazilian Organosols
ABSTRACT Despite limited geographic expression of Organosols in Brazil, their high carbon storage capacity and natural environmental vulnerability justifies further studies on C and N stocks in these soils and their relationship to the nature of organic matter. Evaluation of physical and chemical properties of organic soils and their ability to store C is im

10. ESTABLECIMIENTO AGROPRODUCTIVO ECOLOGICO VS. AGRICULTURA CONVENCIONAL: PARTIDO DE TANDIL, PROVINCIA DE BUENOS AIRES
ABSTRACT In Argentina, in recent decades, a process known as “agriculturization” has been generated with various environmental impacts. This has led to introducing more sustainable farming models. This paper aims to analyze the sustainability of a rural facility dedicated to organic farming in comparison with conventional agricultural systems located in

11. Mudanças nos uso e preços de terras do Estado de São Paulo - período de 1995 a 2010 / Changes in land use and farmland prices in São Paulo State: from 1995 to 2010
This work has examined major changes in land occupation in different regions of São Paulo State to determine major vectors of the observed changes in farmland prices, between 1995 and 2010. This period encompasses both the period of retraction and deregulation of the sugarcane sector, after the extinction of Proálcool program, and the new stage of investme

12. Avaliação ecotoxicológica do uso de dejetos de suínos em solos de Santa Catarina / Ecotoxicological evaluation of swine manure usage in soils from Santa Catarina State Brazil
O Brasil ocupa a quarta posição entre os maiores produtores mundiais de carne suína. Destaque nacional deve ser dado ao estado de Santa Catarina, que detém 25% da produção do Brasil. Em Santa Catarina, a intensificação da produção em pequena área territorial gera um grande aporte anual de dejetos de suínos por unidade de área agrícola. Isso se
