The determination of the soil pore size distribution, water retention curve, and derived parameters that control important processes in soils, such as supply for plants; infiltration; solute movement soils; erosion; plant nutrients contaminants transport, etc, are challenging available methods expensive, time-consuming prone to bias errors. use 1H Nuclear Magnetic Resonance (NMR) relaxometry characterise porosity hydraulic properties through spin-lattice spin-spin results an ill-posed...
Machinery traffic in sugarcane (Saccharumsp.) plantations reduces soil physical quality, and hinders both root development crop yield. We evaluated the quality of an Oxisol roots under controlled traffic. The treatments assessed were: without machinery (WCT), by adjusting tractor infield wagons to a 3.0 m track width with operator guiding (CT1) previous treatment using real time kinematic / global positioning system (RTK GPS) precision auto steer (CT2). Soil samples were collected from...
A comprehensive digital soil profile database of Brazil was compiled and is being made available through the Internet. Most data were obtained from Radambrasil project other regional surveys. The contains information 5086 profiles distributed over whole Brazilian territory corresponding to 10034 horizons, each with 31 variables. variables chosen represent different areas science, embracing morphological, chemical, mineralogical, physical attributes. distribution uniformity low sampling...
Soil ecosystem service (SES) approaches evidence the importance of soil for human well-being, contribute to improving dialogue between science and decision-making encourage translation scientific results into public policies. Herein, through systematic review, we assess state art SES in tropical regions. Through this 41 publications were identified; while most these studies considered SES, a lack consistent framework define was apparent. Most measured natural capital processes, only three...
The Arya and Paris (AP) model predicts soil water retention curves from particle‐size distribution (PSD) data based on the similarity between these two functions. AP estimates pore radius ( r i ) R of spherical particles by scaling length with a parameter α. This paper evaluates performance representative Brazilian types using three constant α values: = 1.38, 0.938 (literature values), 0.977, (obtained in present work); α‐variable approach, where is determined as function content (θ). study...
Microaggregates that characterize ferralic soils have been hypothesized to physical, geochemical and/or biological origins. Despite of many studies, the hierarchy between these processes form microaggregates has seldom reported. The objective this work was study genesis in a sequence Ferralic Nitisols developed on Quaternary red clayey sediments and diabase Piracicaba (SP), Brazil. This issue tackled by combining optical microscopy, image analysis, scanning electron microscopy elemental iron...
Knowledge of soil hydraulic properties after forest restoration is essential for understanding the recovery hydrological processes, such as water infiltration. An increase cover may improve infiltration and properties, but little known about response extent to which can affect these properties. The purpose this study was investigate effect on surface-saturated conductivity (Ks), verify Ks pre-disturbance conditions. We sampled field at surface in Campinas municipality, São Paulo State,...
In the soil science, a direct method that allows study of pore distribution is bi-dimensional (2D) digital image analysis. Such technique provides quantitative results shape, number and size. The use specific softwares for treatment processing images fast efficient to quantify porous system. However, due high cost commercial softwares, public ones can be an interesting alternative structure objective this work was evaluate quality data provided by Image J software (public domain) used...
Abstract Land use change ( LUC ) alters soil structure and, consequently, the functions and services provided by these soils. Conversion from extensive pasture to sugarcane is one of largest land transitions in Brazil as a result growth domestic global demands bioenergy. However, impacts expansion on under remains unclear, especially when considering changes at microscale. We investigated whether for cultivation impacted microstructure quality. Undisturbed samples were taken two layers (0–10...
Although native vegetation is a determinant of aquatic ecosystems' maintenance, forest restoration has been linked to decreases in water yields worldwide. Here, we clarify linkages between and services identify gaps the literature critical for evaluating benefits on yields. Also, discuss possible strategies improve planning implementation. We argue that apparent disconnect estimates real‐world observation reflects limitation studies, methods, approaches capturing relationships' complex...
Com o objetivo de fornecer dados que ajudem na discussão problemas existentes classificação dos Nitossolos no Brasil, foram estudadas detalhadamente a estrutura, consistência, porosidade, cerosidade, condutividade hidráulica e retenção água solos com horizonte B nítico ambos, latossólico. O comportamento físico-hídrico horizontes perfis estudados mostrou íntima relação existente entre este forma grau bem como abundância intensidade da cerosidade. Os caracterizados apresentaram blocos...

Knowledge of the soil water retention curve (SWRC) is essential for understanding and modeling hydraulic processes in soil. However, direct determination SWRC time consuming costly. In addition, it requires a large number samples, due to high spatial temporal variability properties. An alternative use models, called pedotransfer functions (PTFs), which estimate from easy-to-measure The aim this paper was test accuracy 16 point or parametric PTFs reported literature on different soils south...
