Soil cation exchange capacity (CEC) measures the capability of soils to hold and release nutrients. It is an important measure for classifying planning nutrient additions, but it not included in routine soil tests offered farmers. In this study, we compared CEC measured with standard laboratory practices (neutral ammonium acetate [AAc]) estimated from agronomic test data (Mehlich-3 AAc). We app...

Recent studies have shown that soil particle size analyses using laser diffraction method (LDM) can give compatible results compared with traditional sedimentation based methods, if the clay-silt cutoff is transformed. Additionally, procedures including separation of sand fraction by wet sieving and running a well dispersed sample only fractions smaller than during measurement, given promising ...

Identifying the vulnerability of soils to compaction damage becomes an increasingly important issue in the planning and execution of farming operations. Soil compaction models are efficient tools for predicting soil compaction due to agricultural field traffic. Most of these models require the knowledge of the stress/strain relationship, as well as the mechanical parameters and their variation ...

With regard to the differences between soil particle size distribution (PSD) obtained by sieve-sedimentation methods (SSMs), e.g., sieve-pipette method (SPM) and laser diffraction (LDM), usually, clay fraction content in LDM measurements is lower than SSM. Two groups of reasons can be identified for this. Firstly, resulting from features themselves. Secondly, sample preparation (after sampling)...

Saturated hydraulic conductivity is one of the most essential soil parameters, influencing surface runoff and water erosion formation. Both field laboratory methods measurement this property are time or cost-consuming. On other hand, empirical very easy, quick costless. The aim work was to compare 15 pedotransfer models determination their usefulness for assessment saturated highly eroded loess...
