1. Evaluation of the use of fertilizer obtained from pharmaceutical effluent
Resumo A sustentabilidade envolve um número grande de aspectos. Entre eles, o de aproveitamento de nutrientes presentes em efluentes tratados com diferentes tipos de processos. Nos últimos anos, têm sido detectados danos ambientais decorrentes do despejo de fármacos e de efluentes da indústria farmacêutica, em função da difícil recalcitrância de al

2. Biochar association with phosphate fertilizer and its influence on phosphorus use efficiency by maize
RESUMO O uso de fertilizantes com alguma proteção aos íons fosfato pode diminuir sua adsorção pelo solo e aumentar a absorção pela cultura, o que aumenta a eficiência da adubação. O objetivo deste trabalho foi avaliar o desempenho de um fertilizante fosfatado associado a biocarvão em um solo com alta capacidade de fixação de P. Os biocarvões fo

3. CO-INOCULATION OF GROWTH PROMOTING BACTERIA AND Glomus clarum IN MICROPROPAGATED CASSAVA PLANTS
RESUMO Os fungos micorrízicos arbusculares (FMA) e com as bactérias promotoras de crescimento (BPCPs) beneficiam a sobrevivência e o desenvolvimento de plântulas; tais benefícios são atribuídos ao aumento da absorção de nutrientes, aumento da taxa fotossintética, e aumento da tolerância a estresse abiótico. O objetivo deste estudo foi o de avalia

4. Ajmalicine Bioproduction in Catharanthus Roseus (L) G. Don Inoculated with Arbuscular Mycorrhiza and Fertilized with Nitrogen
ABSTRACT Catharanthus roseus (L) G. Don (Madagascar periwinkle) belongs to the Apocynaceace family and is widely spread throughout tropical and subtropical regions of the world. The plant produces several important alkaloids, such as ajmalicine and serpentine, which are used in the treatment of circulatory diseases. The potential of inoculation with arbuscul

5. SUPPLEMENTATION OF NUTRIENTS FOR TABLE BEETS BY IRRIGATION WITH TREATED DAIRY EFFLUENT
ABSTRACT: This study was conducted to evaluate the nutritional status of table beet plants cultivated in a greenhouse irrigated with treated dairy effluent at different irrigation depths. The experimental design used was a randomized block in a 3 x 3 + 1 factorial arrangement with four replications and conducted in a greenhouse. The treatments consisted of t

6. Maize dry matter production and macronutrient extraction model as a new approach for fertilizer rate estimation
ABSTRACT Decision support for nutrient application remains an enigma if based on soil nutrient analysis. If the crop could be used as an auxiliary indicator, the plant nutrient status during different growth stages could complement the soil test, improving the fertilizer recommendation. Nutrient absorption and partitioning in the plant are here studied and d

7. Phosphorus fractions in soil with a long history of organic waste and mineral fertilizer addition
ABSTRACT Applications for long periods of organic animal waste as a source of nutrients to crops can contaminate the soil and the surface and subsurface waters. This study aimed to evaluate how the utilization of organic waste, after successive applications, affects P fractions in the soil and consequently environmental contamination. In an experiment conduc

8. Strategy of Sample Preparation for Arsenic Determination in Mineral Fertilizers
A method for determination of arsenic in mineral fertilizers by continuous flow hydride generation atomic absorption spectrometry (CF-HG-AAS) was developed by using diluted acid and digester block with perfluoroalkoxy (PFA) tubes to sample preparation. An additional sample preparation procedure using microwave-assisted digestion was evaluated and compared wi

9. Nitrogen contributions of legume roots to cabbage nutrition
The effects of roots are generally not considered in studies assessing crop responses to green manure. However, measuring such effects can contribute to a better understanding of crop rotation. In two experiments, we evaluated the content of legume-N in crop tissue and the fertilizer value of the roots and shoots of two legume species. Roots, shoots, or whol

10. CHARACTERIZATION AND EVALUATION OF INTERACTION BETWEEN SPECIES AND METAL HUMIC SUBSTANCES OF PEAT: an alternative for remediation of soil and surface water in the arid region of Sergipe. / CARACTERIZAÇÃO E AVALIAÇÃO DA INTERAÇÃO ENTRE ESPÉCIES METÁLICAS E SUBSTÂNCIAS HÚMICAS DE TURFA: uma alternativa para remediação de solos e águas superficiais na região do agreste sergipano.
This study aimed to understand the interactions between humic substances extracted from peat and metallic species, of the National Park of Itabaiana - SE, seeking a further application in the remediation of soil, surface water contaminated by agricultural activities. We collected samples of soil, fertilizer and peat and characterized by the organic matter co

11. Resposta da cultura do milho aos fertilizantes fosfatados e nitrogenados revestidos com polímeros / Response of maize to polymer-covered phosphate and nitrogen fertilizers
The effective use of fertilizers, besides resulting in greater yield, can reduce production costs, with positive results in the end of the cropping season. Soil correction and fertilization in intensive maize production systems represent, on average, 40% to 45% of the production cost. Phosphorus is considered as a nutrient with low absorption by plants due t

12. Fosfato monoamônio revestido com polímeros no plantio das culturas de milho irrigado e cana-de-açúcar
Phosphorus (P) is the most limiting nutrient, in tropical conditions, for crop yield, mostly due to its low contents and high fixation in soils. Moreover, it is common to observe low efficacy of phosphate fertilizers, with plant absorption varying from 20% to 30%. Therefore, the reduction of phosphate fertilizers expenses and, or, increasing its efficacy, co
