Soil classification can also play a role since its function is to group soil properties into soil types and create maps that show soil patterns across the landscape. In addition, classification is based largely
Due to this relationship, many researchers have used it to predict a number of soil properties and to assess threats such as degradation to soil and soil classification (Ben-Dor and Banin, 1995; Islam et al., 2003; Awiti et al., 2008). Show moreView chapter Book series 2013, ...

but had otherwise a limited effect on microbial carbon values in the rest of the range above zero up to 28.9 °C. Based on partial predictions (Supplementary Figs.1–2), microbial carbon decreased monotonically with an increase in temperature (with all...
There were no significant effects regarding the interaction term (Table 1), showing that precipitation during the wettest months was not linked to the presence of Veredas in each classification type, so that higher levels of precipitation during the wettest months were not a factor regarding the ...

Addition of lime to reduce the acidity of forests soils was frequently tested in Central and Western Europe, where many trials were set up (Kreutzer1995; Huber and others2006a,b; Kunes and others2007; Court and others2018). A number of liming experiments were also carried out in Norway, Fi...
This classification could be useful as a basis for targeting agronomic advice and inputs to farmers. The results suggest that soil fertility variability patterns on smallholder farms are reinforced by farmers investing more resources on already fertile fields than on infertile fields. CART proved a ...
Their type and structure are influenced by (a) soil texture, (b) erosion and deposition effects by wind and water, and (c) vegetation cover. Their distribution also depends on terrain position, microrelief and the impact of wind. The crusts are usually formed during the 2–4 months of ...
Classification and Function of Root Derived Products Newman (1985) examined a variety of plant species and estimated that roots can release anywhere from 10 to 250 mg C /g root produced or about 10-40% of their total photosynthetically fixed carbon. The C released is in both organic (e.g....
