We examined three soil maps of Zambia, two published at scales 1:1 million – the Exploratory Soil Map Zambia (ESMZ) and Vegetation–Soil produced by Trapnell colleagues in 1947 one 1:3 million, Atlas Africa (SAA). estimated components variance for measurements clay, sand organic carbon content bulk density across country using models which included different mean values map units as random effects. For all but there was significant variation accounted differences between legend maps, ESMZ...
Predictions of soil hydraulic properties by pedotransfer functions (PTFs) must be treated with caution when they are used in an application domain which differs from the their original development and calibration. However, some settings, scientists may have little alternative but to use PTFs calibrated elsewhere. In this paper we consider how legacy data can evaluate new regions, paying particular attention challenges that arise when, as is often case, not obtained independent random...
The boundary line model has been proposed for interpretation of the plot a biological response (such as crop yield) against potentially-limiting variable from observations in large set scenarios across which other factors show uncontrolled variation. Under this upper bound distribution data represents limiting effect potential factor on response. Methods have to fit model, but we propose that an initial exploratory analysis step is needed evaluate evidence (i) plausible and (ii) any...
