Andisols from Tondano Area, North Sulawesi: Properties and Classification

open access: yesJournal of Tropical Soils, 2008
Three pedons of Andisol (TN-1, TN-2 and TN-3) developed from young volcanic materials of the Lokon, Soputan, and Lengkoan volcanoes respectively in the Tondano area, North Sulawesi, were studied in the field, and 18 soil samples were analysed in the ...

Fluid fertilizers improve phosphorus diffusion but not lability in andisols and oxisols

open access: yes, 2014
Fluid phosphorus (P) fertilizers increase availability of P in calcareous soils compared with granular fertilizers, because of reduced P precipitation. It is unclear whether fluid P forms may also enhance fertilizer P availability in acidic soils. A 35-d

Characteristics of non-allophanic andisols with hydric properties from the Ecuadorian paramos

open access: yes, 2003
So far, the occurrence of hydric properties (i.e. water retention values at 1500 kPa matrix potential larger than 1000 g kg(-1)) has generally been reported in Andisols characterised by advanced stages of weathering. Moreover, as these properties are due

Improving Phosphate Efficiency by Phosphate Solubilizing Bacteria and Organic Matter Estimated by Radio Isotop (32P) Technique in Some Soils

open access: yesJournal of Tropical Soils, 2012
Phosphorous (P) contents in many soils are varies highly along with their ability to provide available P to plant growth. Soils may contain very high in total P, but low in available P due to high P adsorbed by soil matrix and all their adsorbing agents.

Characteristics of non-allophanic andisols derived from low-activity clay regoliths in the Nilgiri Hills (Southern India)

open access: yes, 2000
Low-activity clay soils on old planation surfaces of the tropics are generally considered as stable end points of soil formation. It is therefore surprising to find Andisols on them. We characterized the properties of six profiles representative of these

Extracción de Sustancias Hidrofóbicas de Andisols Repelentes al Agua del Oriente Antioqueño, con Solventes Polares

open access: yesRevista Facultad Nacional de Agronomía Medellín, 1997
Muestras de Andisols repelentes al agua fueron sometidas a extracciones con mezclas de solventes orgánicos de diferentes polaridaddes; los lavados con mezclas de polaridades 5 y 6 removieron completamente la hidrofobicidad del suelo, sin importar el ...
