1. GEOSTATISTICAL MODELING OF SOYBEAN YIELD AND SOIL CHEMICAL ATTRIBUTES USING SPATIAL BOOTSTRAP
ABSTRACT The goal of this study was to use the spatial bootstrap method to model the spatial dependence structure of soybean yield and soil chemical attributes in an agricultural area. The study involved developing confidence intervals in probability plots to determine the probability distributions assumed by the data; determine the empirical distributions o

3. Cattle Manure Bioconversion Effect on the Availability of Nitrogen, Phosphorus, and Potassium in Soil
ABSTRACT The efficiency index (EI) refers to the ratio of nutrients mineralized/made available in the soil to the total amount of nutrients added by organic fertilizer. Therefore, understanding the EI is essential for recommendation of organic fertilization. The aim of this study was to evaluate the availability through mineralization and the efficiency inde

4. 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

5. Mineralocorticoid replacement during infancy for salt wasting congenital adrenal hyperplasia due to 21-hydroxylase deficiency
OBJECTIVE: The protocols for glucocorticoid replacement in children with salt wasting 21-hydroxylase deficiency are well established; however, the current recommendation for mineralocorticoid replacement is general and suggests individualized dose adjustments. This study aims to retrospectively review the 9-∝-fludrocortisone dose regimen in salt wasting 21

6. Biofertilizante de rochas mais matéria orgânica inoculada com bactéria diazotrófica na cana-de-açúcar.
Sugarcane (Saccharum spp.) Is currently considered one of the most important crops in the Brazilian social and economic. In Pernambuco, the sugar cane industry occupies an important agricultural area with high sugar and ethanol, generating many direct and indirect jobs. For increased productivity becomes necessary the use of management technologies that fost

7. Variable rate application of potassium fertilizer for soybean crop growth in a no-till system.
Variable rate application of fertilizer has the potential to improve nutrient use efficiency, improve economic returns, and reduce negative environmental impacts. The objective of this study was to evaluate the variable rate application of potassium fertilizer to soybean crop in a no-till system. The study was conducted on a 13-ha soybean grain field in Cara

8. Establishment of recommendations and parameters for use of urban waste compost in agriculture in the State of Sao Paulo - Brazil.
The organic matter present in urban waste (45 to 60% of total dry mass), after being stabilized in the form of compost, is recommended for application in agricultural soils, since it improves its physical and chemical properties and benefits the soil biological processes. Also, the urban waste compost has been economically viable for application in agricultu

9. Effects of fertirrigation with effluent of primary treatment of wastewater from swine on the soil and in the productivity and quality of tomato (Lycopersicon esculentum Mill.) / Efeitos da fertirrigação com efluente do tratamento primário da água residuária da suinocultura no solo e na produtividade e qualidade do tomate (Lycopersicon esculentum Mill.)
In this study was analyzed the effects of fertirrigation with filtrated wastewater from swine (FWS) on soil and the physiological, sanitary variables and of tomato production, in drainage lysimeters under protected environment. The experiment was carried out in the lysimeter station at the Hydraulic, Irrigation and Drainage Experimental Area, in campus of th

10. Added sugar consumption in adults and elderly Population-based survey in São Paulo city / Consumo de açúcares de adição entre adultos e idosos: inquérito populacional do município de São Paulo
Scientific evidences point to the undesirable effects of the added sugar in the health, such as: dental caries, excess of energy intake and, consequently, weight gain and dilution of nutrients. The World Health Organization recommends to limit the consumption in 10 % of the energetic intake (EI) from added sugar. In spite of Brazil is one of the principal wo

11. Nitrogen, phosphorus and potassium recommendation for sunflower under no-tillage system in Paraguay / RECOMENDAÇÃO DE NITROGÊNIO, FÓSFORO E POTÁSSIO PARA GIRASSOL SOB SISTEMA PLANTIO DIRETO NO PARAGUAI.
Sunflower crop has some important agronomic characteristics, as great fitomassa production, larger resistance to the drought, cold and heat than most of the cultivated species and wide adaptability to different conditions of soil and climates. Its deep root system provides absorption of nutrients of the deepest layers, ciclying great amounts of nitrogen (N),
