Decoupling of soil nutrient cycles as a function of aridity in global drylands
(Springer Nature, 2013-10-30)
The biogeochemical cycles of carbon (C), nitrogen (N) and phosphorus (P) are interlinked by primary production, respiration and decomposition in terrestrial ecosystems1 . It has been suggested that the C, N and P cycles ...
Hierarchical linear mixed models in multi-stage sampling soil studies
(Springer, 2013-06)
The issue of variances of different soil variables prevailing at different sampling scales is addressed. This topic is relevant for soil science, agronomy and landscape ecology. In multi-stage sampling there are randomness ...
Improving Estimation of Specific Surface Area by Artificial Neural Network Ensembles Using Fractal and Particle Size Distribution Curve Parameters as Predictors
(Springer, 2013)
Specific surface area (SSA) is one of the principal soil properties used in modeling soil processes. In this study, artificial neural network (ANN) ensembles were evaluated to predict SSA. Complete soil particle-size ...
Continuous application of direct sowing: Traffic effect on subsoil compaction and maize (Zea mays L.) yields in Argentinean Pampas
(2013-11)
Our main objective was to evaluate the effect of subsoil compaction on maize (Zea mays L.) yields. This work was performed on clayey soil and on loamy Entic Haplustoll soil. Three types of direct sowing (DS) equipment ...
A new dust generator for laboratory dust emission studies
(Elsevier, 2013-03)
The aim of this study was to develop a cheap and replicable dust generator for production and investigation of fugitive dusts. We call the device the Easy Dust Generator (EDG). The EDG was constructed with common materials ...
