“…The ability of these minerals to bind hygroscopic water is similar to their ability to include caesium in their lattice structure. This is in accordance with the results of Wudivira et al (25) who used hygroscopic water measurements at 50 % atmospheric relative humidity to estimate site-specifi c clay mineral content. All this suggests that hygroscopic moisture is an important and useful soil parameter that deserves further investigation, but it cannot serve as a fundamental soil characteristic unless multiple environmental factors are eliminated by standardised measurement (23,25).…”

This is a preliminary study of the depth distribution of (137)Cs radionuclides in cultivated anthrosol soil of a 15-year old peach tree plantation at the experimental field "Radmilovac" near Belgrade. Before planting, the soil was ploughed at the depth of 1 m. The soil had not been annually ploughed, irrigated and treated with mineral fertilizers for three years before sampling. Activity concentration for (137)Cs ranged from 1.8 Bq kg(-1) to 35 Bq kg(-1). Along the soil depth it varied highly, reaching as high a total variation coefficient as 83 %. Radiocaesium distribution patterns depended on the extent of soil mixing in the plough layer, as it was mechanically transferred from the surface to the lower soil layers during cultivation. (137)Cs was associated with humus content and fixation to clay fractions in the soil. Our results single out soil's hygroscopic water as a valuable parameter for (137)Cs behaviour that could be used commonly if the measurement is standardised.

“…The ECa correlates with various soil properties such as salinity (Rhoades et al, 1999), clay content (Triantafilis &Lesch, 2005 andWuddivira et al, 2012), water content (Haimelin, 2008) and carbon content (Martinez et al, 2009). The ECa can be used as an indirect indicator for identifying some important soil properties including soil salinity, clay content, cation exchange capacity, soil moisture content, and temperature (McNeill, 1992 andRhoades et al, 1999).…”

“…Electromagnetic induction (EMI) sensors noninvasively measure the spatial variations of soil apparent electric conductivity (Atwell et al, 2013;Bréchet et al, 2012Rossi et al, 2013and Wuddivira et al, 2012. Electromagnetic induction methods are much less labor, cost and time intensive as the volume of measurement is larger than traditional point soil sampling (Rhoades et al, 1999).…”

“…Electromagnetic induction (EMI) sensors such as DUALEM-1S EC meter employ geophysical imaging techniques to rapidly, non-invasively measure spatial variations of soil ECa (Atwell et al, 2013;Bréchet et al, 2012;Rossi et al, 2013;Wuddivira et al, 2012). Apparent soil electrical conductivity correlates with va rious physicochemical soil properties such as salinity (Rhoades et al, 1999), clay content (Triantafilis and Lesch, 2005;Wuddivira et al, 2012), water content (Haimelin, 2008) and carbon content (Martinez et al, 2009).…”

Recently, Atwell et al (2013) and Bréchet et al (2012) showed that under humid tropical conditions, variation in ECa was influenced by temporal changes in soil moisture content, spatial variation of claysilt mineral content, soil solution electrical conductivity (ECe) and soil water repellency.…”

A b s t r a c t. Cocoa remains in the same field for decades, resulting in plantations dominated with aging trees growing on variable and depleted soils. We determined the spatio-temporal variability of key soil properties in a (5.81 ha) field from the International Cocoa Genebank, Trinidad using geophysical methods. Multi-year (2008Multi-year ( -2009) measurements of apparent electrical conductivity at 0-0.75 m (shallow) and 0.75-1.5 m (deep) were conducted. Apparent electrical conductivity at deep and shallow gave the strongest linear correlation with clay-silt content (R = 0.67 and R = 0.78, respectively) and soil solution electrical conductivity (R = 0.76 and R = 0.60, respectively). Spearman rank correlation coefficients ranged between 0.89-0.97 and 0.81-0.95 for apparent electrical conductivity at deep and shallow, respectively, signifying a strong linear dependence between measurement days. Thus, in the humid tropics, cocoa fields with thick organic litter layer and relatively dense understory cover, experience minimal fluctuations in transient properties of soil water and temperature at the topsoil resulting in similarly stable apparent electrical conductivity at shallow and deep. Therefore, apparent electrical conductivity at shallow, which covers the depth where cocoa feeder roots concentrate, can be used as a fertility indicator and to develop soil zones for efficient application of inputs and management of cocoa fields.
