1. Alternative budburst management in Campanha Gaúcha vineyards
Resumo Buscando uma alternativa menos tóxica que a cianamida hidrogenada para o manejo da brotação, doses do produto organomineral Erger® foram testadas em combinação com nitrato de cálcio (Ca(NO3)2). O experimento foi conduzido em Santana do Livramento, região Sul do Brasil, durante os ciclos de 2013/2014 e 2014/2015, em um vinhedo ‘Merlot’, co

3. Wood ash and water availability in the production of Paiaguás-grass
Resumo Objetivou-se avaliar a produção do capim-paiaguás (Urochloa brizantha) em função de doses de cinza vegetal e disponibilidades hídricas do Latossolo Vermelho do Cerrado. O experimento foi realizado em casa de vegetação com delineamento em blocos casualizados em esquema fatorial 5x5 fracionado, correspondendo a cinco doses de cinza vegetal (0; 8

4. Phosphorus acquisition by wheat from organic and inorganic sources labelled with 32P and 33P radioisotopes
ABSTRACT: Investment in soil phosphorus (P) capital in the tropics is often constrained by poor availability of mineral fertiliser to small-scale farmers. Consequently, new sustainable agricultural cropping strategies are required to maintain fertility and maximise crop yields. The co-application of Tithonia diversifolia (Tithonia) green manure and mineral f

5. Adubação com potássio e cálcio na nutrição e produção de goiabeira 'Paluma'
RESUMO A goiabeira é uma frutífera cultivada mundialmente, destacando-se pela grande aceitação no mercado consumidor. Entretanto, para que a cultura explore o seu máximo potencial produtivo e mantenha a qualidade dos frutos, é necessária a adequada adubação mineral para elevar a disponibilidade de nutrientes no solo e aumentar sua absorção pelas p

6. Contribution of Eucalyptus Harvest Residues and Nitrogen Fertilization to Carbon Stabilization in Ultisols of Southern Bahia
ABSTRACT: Eucalyptus forests in southern Bahia (BA) are planted in soils with a sandy surface layer and humid tropical climate, conditions that lead to soil carbon (C) decomposition. Recent studies have shown that nitrogen (N) may be important for soil C stabilization. The aim of this study was to evaluate the contribution of Eucalyptus harvest residues and

7. 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

8. Poultry Litter and Pig slurry Applications in an Integrated Crop-Livestock System
ABSTRACT Organic fertilizers derived from poultry litter and pig slurry are alternatives to mineral fertilizers in increasing soil nutrient availability. The aim of this study was to evaluate soil response, through characterization of organic C and available N, P, and K contents, and corn yield response to increasing amounts of poultry litter, pig slurry, an

9. Evaluation of the technological, nutritional and sensory qualities of bakery products produced with partial substitution of the wheat flour by whole rice flour
Summary The objective of this work was to determine the technological, nutritional and sensory characteristics of bread produced by substituting 25 and 50% of conventional wheat flour by whole rice flour (Oryza sativa L). The final products were evaluated in terms of specific loaf volume, appearance of the central slice, crumb firmness, moisture content, die

10. Soil Solution Nutrient Availability, Nutritional Status and Yield of Corn Grown in a Typic Hapludox under Twelve Years of Pig Slurry Fertilizations
ABSTRACT Nutrient content in soil solution may vary in response to the applied amount of pig slurry (PS). Thus, the aim of this research was to evaluate the nutrient content in soil solution and its relationship to nutritional status and yield of corn under 12 years of annual fertilization with increasing doses of PS, soluble mineral fertilizer (MF) and PS c

11. Changes in Soil Organic Carbon and Nitrogen Stocks in Long-Term Experiments in Southern Brazil Simulated with Century 4.5
ABSTRACT The Century model has successfully simulated soil organic matter dynamics in many agroecosystems. However, initial applications in southern Brazil produced mixed results. The objective of this study was to calibrate and validate Century 4.5 to simulate soil carbon (C) and nitrogen (N) dynamics under diverse soil management practices in subtropical B
