25. Leaf-associated bacterial microbiota of coffee and its correlation with manganese and calcium levels on leaves
Abstract Coffee is one of the most valuable agricultural commodities and the plants’ leaves are the primary site of infection for most coffee diseases, such as the devastating coffee leaf rust. Therefore, the use of bacterial microbiota that inhabits coffee leaves to fight infections could be an alternative agricultural method to protect against coffee dis

26. Soil Physical and Chemical Properties in Epigeal Termite Mounds in Pastures
ABSTRACT We characterized soil physical and chemical properties and soil organic matter in epigeal termite mounds in pastures to evaluate the changes promoted by termites in comparison to an adjacent area. We selected seven active epigeal termite mounds in the municipality of Seropédica, state of Rio de Janeiro, Brazil. Soil samples were collected from top

27. 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

28. Novel Food Supplements Formulated With Spirulina To Meet Athletes’ Needs
ABSTRACT The food, training, and health are crucial for a good performance in sports. Intense physical activity takes the athlete to maintain a very unstable balance between energy demand and consumption of nutrients. Spirulina microalga has a nutritional profile that renders it an ideal food supplement, because has high protein content, also contains vitami

29. SWINE WASTEWATER: IMPACTS ON SOIL, PLANT, AND LEACHATE
ABSTRACT: The use of animal-origin residues as a nutrient source without prior and proper investigations on their positive and negative impacts can affect the quality of agricultural soils and the environment into which they are inserted. In this sense, the aim of this study was to assess the impact of swine wastewater and mineral fertilization application o

30. Nutritional value of Brazilian distillers dried grains with solubles for pigs as determined by different methods
ABSTRACT The objective of this study was to determine the digestibility coefficient (DC) of nutrients and the digestible energy (DE), and metabolizable energy (ME) values of distillers dried grains with solubles (DDGS) produced in Brazil by different methods. Eight barrows with 23.3±4.1 kg were housed in metabolic cages in a randomized block design and fed

31. Mineralogy of the Clay Fraction and Chemical Properties of Soils Developed from Sedimentary Lithologies of Pirambóia, Sanga-the-Cabral and Guará Geological Formations in Southern Brazil
ABSTRACT Quali-quantitative and crystallographic characterizations of the different minerals of a soil are essential for the best evaluation of its genesis, degree of weathering, active pedogenetic processes, physical and chemical properties, and its potential reserve of mineral nutrients. This study presents the results of mineralogical investigations carri

32. Soil chemical properties and nutrients in maize fertilized with urban waste compost1
RESUMO Atributos químicos do solo e nutrientes em milho adubado com composto de lixo urbano O composto de lixo urbano tem potencial de uso na agricultura como fertilizante orgânico, mas estudos em condições de campo são necessários para a definição das doses recomendadas para as culturas. Objetivou-se avaliar o efeito da adubação com composto de li

33. Soluble amino acid profile, mineral nutrient and carbohydrate content of maize kernels harvested from plants submitted to ascorbic acid seed priming
ABSTRACT Both the scientific community and society have shown interest in improving the content of amino acids, carbohydrates and mineral nutrients in maize because it represents an important staple food in many developing countries. Earlier studies demonstrated that the treatment of seeds using ascorbic acid (AsA-seed priming) enhanced soluble carbohydrates

34. CHANGES IN SOIL CHEMICAL PROPERTIES PROMOTED BY FERTIGATION WITH TREATED SANITARY WASTEWATER
ABSTRACT We evaluate the application of treated sanitary wastewater (TSW) to provide potassium for crops and reduce demand for fresh water and mineral nutrients. The field experiment was arranged in randomized block design with four replications and five treatments: 50, 100, 150 and 200% of potassium requirements and a control with conventional fertilizer. T

35. 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

36. Digestibility, Determination of Metabolizable Energy and Bone Mineralization of Broilers Fed with Nutritionally Valued Phytase
ABSTRACT The objective of this study was to evaluate the effect of using exoenzyme phytase in broiler's diets on digestibility of nutrients, feed energy and tibia bone mineralization. A completely randomized design was used, with the following treatments: sorghum with dicalcium phosphate (SDP), corn with dicalcium phosphate (CDP), sorghum with meat and bone
