1. An Evaluation of the Use of Statistical Procedures in Soil Science
ABSTRACT Experimental statistical procedures used in almost all scientific papers are fundamental for clearer interpretation of the results of experiments conducted in agrarian sciences. However, incorrect use of these procedures can lead the researcher to incorrect or incomplete conclusions. Therefore, the aim of this study was to evaluate the characteristi

2. Qualidade física da cama de semeadura do solo em sistemas de manejo / Physical quality of the soil seedbed under management systems
The seedbed is one of the most important soil physical conditions for plant growth. The evaluation of the soil physical quality in such soil environment is essential to understand the factors that affect crop development, as it is where seed germination and plant emergence and establishment take place. The objective of the experiment carried out in Brazil wa

4. EFEITO DO MANEJO DO SOLO E DO GESSO RESIDUAL NA CULTURA DA SOJA E EM ATRIBUTOS FÍSICOS DE UM LATOSSSOLO VERMELHO DISTROFÉRRICO / SOIL MANURE AND RESIDUAL GYPSUM EFFECT ON THE SOYBEAN CROP AND IN PHYSICAL ATTRIBURES OF DYSTROPHIC RED LATOSOIL
Adoption of soil manure systems with or without conditioners can improve or reduce its physical quality, changing the answers of crops to the same ones. Thus, this paper aimed to evaluate the agronomic performance of soybean crop and the soil physical attributes. The paper was conducted in an area granted under a lending to Faculdade de Ciências Agrárias d

5. Integrated crop-livestock and soil physical quality in Brazilian Cerrado / IntegraÃÃo Lavoura-PecuÃria e a Qualidade FÃsica do Solo na RegiÃo do Cerrado
Soil physics plays a fundamental role in conserving soil and water in agricultural landscapes and is also a key parameter for accessing the sustainability of agropastoral systems. Both pasture history and management can have a significant effect on soil physical attributes, but conclusive research on this subject remains fragmentary. This work aimed to quant

6. SOIL PHYSICAL AND BIOLOGICAL CHARACTERIZATION AFTER HERBICIDES APPLICATION IN BLACK WATTLE (Acacia mearnsii De Wild.) STANDS IN RIO GRANDE DO SUL / CARACTERIZAÇÃO FÍSICA E BIOLÓGICA DO SOLO APÓS APLICAÇÃO DE HERBICIDAS EM PLANTIOS DE ACÁCIA-NEGRA (Acacia mearnsii De Wild.) NO RIO GRANDE DO SUL
The study of soil quality biological indicators in areas classified as forest production units is important to understand the ecological processes that occur in these systems. Monitoring the soil fauna in modified environments, when management practices involve chemical products in the environment, is an instrument that allows to evaluate not only the soil q

7. Survey of one Inceptisol soil attributes influenced by different management system of rice crops in North of Italy / LEVANTAMENTO DOS ATRIBUTOS DE UM INCEPTISOL INFLUENCIADOS POR DIFERENTES SISTEMAS DE CULTIVO DE ARROZ NO NORTE DA ITÁLIA
Considering FAO data that indicate that more than 90% of rice production in the world was to human feeding, become more and more important studies to search improve the rice yields index in sustainable form. Apart from this aspect, rice crops exploration required constant management of submersion water and special care relating to criterion for contamination

9. Manejo de coberturas do solo e de plantas espontâneas em pomar orgânico de maçã. / Soil cover and weed management in na organic apple archard.
The demand for healthy and non-contaminated foods has increased between the consumers that become more and more exigent in terms of quality. The organic products appear as an option for the requirements of these consumers. However, research involving the organic production of fruits is still incipient. Thus, this study was carried out to evaluate the weed co

10. Avaliação da qualidade física de solos em pastagens degradadas da Amazônia / Evaluation of the soil physical quality in degraded pastures of the Amazonian
A região amazônica possui extensas áreas que foram desmatadas e convertidas em sistemas de pastagens. A falta de técnicas na implantação e no manejo destes sistemas resultou em inúmeras áreas de pastagens degradadas. A condução de experimentos de campo visando a reversão deste quadro está sendo avaliada no presente estudo. A área em estudo está

11. "Tomografia computadorizada, atenuação de raios gama e análise micromorfológica na avaliação de alterações na estrutura e retenção de água pelo solo" / Computed tomography, gamma-ray attenuation, and micromorphologic analysis to evaluate changes on soil structure and water retention
Soil structure is related to the arrangement of soil particles, aggregates, and pores, which makes part of this porous media. The influence of structure on soil physical phenomena ranges from macro to microscope scale. Structure changes in microscope scale are important because affect the soil particle arrangement and, consequently, the pores distribution. S

12. Sistemas de manejo agricola, qualidade do solo e o controle da erosão em parcelas experimentais / Agricultural management systems, soil quality, and erosion control in experimental plots
O crescimento populacional e o desenvolvimento sustentam a demanda por alimentos e fibras e elevam a pressão sobre o uso da terra. O uso intensivo das terras comumente traz como conseqüência a degradação dos recursos naturais. A erosão, um importante processo de degradação, leva ao empobrecimento do solo, à diminuição da capacidade de produzir boa
