Although physiography continued to be a primary basis of soil mapping, soil associations were used in 56% of the maps.
However, most indicators were not developed on the basis of soil loss progresses, and therefore their specific relationships with soil loss are difficult to construct.
The basic properties that can influence the behaviour of nanocomposites, i.e. texture, organic carbon, pH and electrical conductivity, were determined on the basis of soil fraction according to the standard procedure reported in the Methods of Soil Analysis (SSSA Book Series, Methods in Soil Analysis 1996).
Treatments involved four MWC rates (0, 1, 2, and 4% on the basis of soil dry weight) and four N levels (0, 50, 100, and 200 mg kg−1 soil).
Treatments consisted of four levels of MWC (0, 1, 2, and 4% on the basis of soil dry weight) and four N rates (0, 50, 100, and 200 mg kg−1 soil as urea) arranged in a factorial manner into a completely randomized design with three replications.
Four different fields were considered on the basis of soil texture variations; especially changes in sand percentage were made.
The aim of the analyses presented was to derive a zoning of forest health conditions in Saxony on the basis of soil, topographic and vegetation parameters.
In the BCM, AET is calculated on the basis of soil moisture content that diminishes over the dry season; therefore, in Mediterranean climates with minimal summer precipitation, PET exceeds AET, thus accumulating the annual deficit.
A total of 74 farms were selected from Machakos, Mwingi and Makueni districts in Kenya, using participatory techniques and classified in three categories on the basis of soil fertility management (low level, medium and high level).
This pilot study provided a technical reference for the use of REEs in monitoring sediment sources from a natural watershed, and a theoretical basis for soil conservation in the Three Gorges Area.
