Reliability of Andisol Field Texture Clay Estimates
Soil Survey Horizons, 1999Particle‐size analyses are commonly run to standardize the description of field textures of most kinds of soils. Andisols are an exception, because they do not disperse completely. Failure to disperse completely, and the smeary feel of Andisols in contrast to the sticky feel of most other kinds of soils, cause some to question the ...

Macropores regulate CO2 behavior in an andisol soil
Paddy and Water Environment, 2018Macropores resulting from soil pedogenesis, biological activity, and agricultural practices play important roles in soil water, chemical and gas transport; however, seldom studies focus on the effect of soil macropores on CO2 behavior. In this study, a 150-day soil column incubation experiment was conducted to investigate the CO2 behavior in a ...

Predictive Models for Selected Chemical Properties of Andisols
Soil Survey Horizons, 2001Particle size and chemical properties are important in interpretations for many soils. In this study, statistical models developed from field textures, or apparent textures, and simple chemical tests predict the commonly measured chemical properties of Andisols.

Improving phosphorus availability in Andisols and Oxisols
2016Low phosphorus (P) availability limits plant growth in many soils, particularly in Andisols and Oxisols, due to their large content of minerals that strongly sorb P (e.g. Al/Fe oxyhydroxides, allophane). Because of the strong P retention, P fertilizer requirements are high in these soils.
