Pedotransfer functions to predict water retention for soils of the humid tropics: a review

Abstract: SUMMARYOver the past three decades, pedotransfer functions (PTFs) have been widely used by soil scientists to estimate soils properties in temperate regions in response to the lack of soil data for these regions. Several authors indicated that little effort has been dedicated to the prediction of soil properties in the humid tropics, where the need for soil property information is of even greater priority. The aim of this paper is to provide an up-to-date repository of past and recently published articles as w… Show more

“…A similar SVM approach was employed by Twarakavi et al (2009) to develop parameter-based PTFs for van GenuchtenMualem models. The SVM approach has not yet been applied for soils in the humid tropics (Botula et al, 2014).…”

“…Several phenomena depend on soil water retention, including plant growth and nutrient absorption, leaching of nutrients and pollutants, irrigation and drainage, hydrological recharge and modeling, and biochemical processes and microbial activity, among others. Water retention is determined and modeled in laboratory conditions; however, its measurement is time-consuming and costly, especially in tropical climates, where the soil properties vary widely and data are scarce (HARTEMINK, 2002;COSTA et al, 2013;BOTULA et al, 2014).…”

“…Sá et al (2009) Fonte: Modificado de Minasny e Hatermink (2011) Independentemente de qual método é utilizado de FPT's para estimar propriedades hidráulicas do solo, estes podem ser classificados de diversas formas. Neste estudo, foram classificadas em pontual, paramétrica e pseudocontínua (WÖSTEN et al, 2001;SHARMA et al, 2006 Botula (2014) A respeito dos parâmetros de entrada, estes podem ser os mais variáveis possíveis. De maneira geral as frações granulométricas são os mais usuais, todavia podem ser utilizados ainda a massa específica seca de campo, conteúdo de matéria orgânica, pH, CTC, superfície específica, dentre outros.…”
