1. Relief Position and Soil Properties under Continuous Banana Cropping in Subhumid Climate in Northeast Brazil
ABSTRACT Sequences of thick and eroded soils in hills surfaces are cultivated with banana since the beginning of the last century in the Northeast of Pernambuco (PE), Brazil. Measurements of soil properties depending on soil slope under intensive agricultural cultivation are limited mostly as the pedogenetic approach. This study aimed to identify the dominan

2. Reforested soil under drip irrigation with treated wastewater from poultry slaughterhouse
RESUMO A disposição de efluentes tratados sobre o solo pode ser considerada o principal destino final de águas residuárias no Brasil. Embora possa promover melhorias em relação a alguns atributos do solo, esta prática precisa ser monitorada para garantir que os impactos ambientais não sejam negativos. Assim, objetivou-se com este trabalho avaliar os

3. TRANSITION FROM SYSTEMATIC TO DIRECTED SOIL SAMPLING DESIGNS IN AN AREA MANAGED WITH PRECISION AGRICULTURE
ABSTRACT In agricultural areas with a historical of systematic soil sampling, alternative methodologies such as directed sampling design based on management zones (MZ) have been proposed to reduce sampling costs. The aim of this study was to evaluate the technical and economic impacts of replacing a dense systematic soil sampling design (cell size of 0.5 ha)

4. SOIL CHANGES AND YIELD OF MAIZE FERTILIZED WITH SWINE WASTEWATER
RESUMO A água residuária da suinocultura pode ser usada como biofertilizante e promover melhorias significativas nos atributos físico-químicos do solo e na produtividade. Objetivou-se avaliar os efeitos da aplicação da água residuária da suinocultura no solo e na produtividade do milho-verde. O experimento foi conduzido no Centro de Ciências Agrári

5. SOIL CHEMICAL PROPERTIES IN BANANA CROPS FERTIGATED WITH TREATED WASTEWATER
RESUMO Estabelecer os efeitos da aplicação de águas residuárias nos atributos químicos do solo permite o reúso agrícola seguro desses efluentes. Objetivou-se avaliar as alterações nos atributos químicos de um Latossolo no semiárido, cultivado com banana 'Prata-Anã' fertirrigada com diferentes doses de água residuária sanitária após tratamento

6. Crop Response to Gypsum Application to Subtropical Soils Under No-Till in Brazil: a Systematic Review
ABSTRACT The use of gypsum to improve the root environment in tropical soils in the southeastern and central-western regions of Brazil is a widespread practice with well-established recommendation criteria. However, only recently gypsum began to be used on subtropical soils in South of Brazil, so available knowledge of its effect on crop yield is incipient a

7. 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

8. Abundance and Diversity of Soil Macrofauna in Native Forest, Eucalyptus Plantations, Perennial Pasture, Integrated Crop-Livestock, and No-Tillage Cropping
ABSTRACT Intensive land use can affect macrofaunal biodiversity, which is a property that can be used as a soil quality indicator. This study evaluated the abundance and diversity of soil macrofauna and its relation to soil chemical and physical properties in five land use systems (LUS) in the eastern region of Santa Catarina. The following LUS were studied:

9. Root Distribution of Peach Rootstocks Affected by Soil Compaction and Acidity
ABSTRACT Root growth can be limited by physical and chemical conditions of the soil. Compacted and acidic soils, where there is an occurrence of exchangeable Al, constitute barriers to use of the soil by plant roots. The hypothesis of this study was that physical and chemical properties of the inter-row soil of a peach orchard influence the root distribution

10. Effects of surface application of dolomitic limestone and calcium-magnesium silicate on soybean and maize in rotation with green manure in a tropical region
Although lime is currently the material most frequently used to ameliorate soil acidity in Brazil, silicate could efficiently replace this source because of its greater solubility and its greater silicon content, which are beneficial for plant development. This study aimed to evaluate the effects of superficial lime and silicate application on soil chemical

11. GESSO AGRÍCOLA E ADUBAÇÃO NITROGENADA NA CULTURA DO MILHO EM SISTEMA PLANTIO DIRETO
A considerably part of the high nitrogen (N) rates applied in corn is not absorbed due root growth restriction by subsoil acidity. Gypsum is able to improve conditions for root growth and lead to greater N uptake efficiency, increasing corn yield. Thus to evaluate the effect of gypsum and N on top dressing on soil chemical attributes, root growth , mineral n

12. Forms of sulfur in Brazilian Oxisols under no-tillage system / Formas de enxofre em Latossolos sob sistema plantio direto
Soil is a critical component of the global sulfur (S) cycle acting as source and a sink for various S species and mediating changes of S oxidation states. However, very little is known about the identities of these specific organic and inorganic S containing molecules, especially in Brazilian soils under no-tillage (NT) system. Thus, the objectives of this s
