Organic Carbon as a Major Differentiation Criterion in Soil Classification Systems the ISRIC WISE) it was concluded that there are sufficient number of categories for expression of the amount, kind and vertical distribution of OC, however several of the definitions are very complicated, and not always consistent throughout the systems. This makes interpretation and also computati

A Novel Method for Measurement of Carbon on Whole Soil Coresimensions and can directly produce results on a volumetric (kg/m.) or gravimetric basis (g/kg). Determinations on cores have been reproduced within 0.1 % C (mass basis) which is the level of sensitivity required. The technique, which can be deployed on cores set out according to an appropriate sampl

Evolutionary Optimization of Spatial Sampling Networks Designed for the Monitoring of Soil Organic Cn regular schemes. Besides, the sequential addition produced suboptimal solutions, becoming less efficient than the simultaneous addition when the number of additional points to be allocated was increased. The optimization technique used in the study, the genetic algorithms, proved to be effective t
