Surface characteristics of soils are one of the main factors controlling processes at the soil-water interface like wetting, sorption or dissolution processes and, thereby, have a high impact on natural soil functions like habitat, filter, buffer, storage and transformation functions. Since surface characteristics, like wettability or repellency, are not static soil properties but continuously ...

Drought potentially affects carbon balance and growth of trees, but little is known to what extent soil plays a role in the trade-off between carbon gain and growth investment. In the present study, we analyzed leaf non-structural carbohydrates (NSC) as an indicator of the balance of photosynthetic carbon gain and carbon use, as well as growth of European beech (Fagus sylvatica L.) saplings, wh...

the role of calcite as related to the chemical behavior of boron (b) in calcareous soils was investigated through an assessment of b adsorption and desorption reactions on and from calcite in four ratios of solid to solution rate, three levels of ionic strength, and within a ph range of 7.5 to 11.5. experimental data indicated that b adsorption is increased by an increase in the solid to soluti...

The aim of this work is to model the occurrence and intensity of calcium carbonate loss in calcareous forest soils under Mediterranean conditions. We have used 193 Spanish forest soils found on limestone parent material considered highly calcareous materials. This data set came from FOREDAF, a database containing 2200 complete soil profiles and all of them covered by forest stands (mainly domin...

Abstract Phosphorus (P) reactions in calcareous soils limit the concentration of P soil solution for plant uptake. Calcareous with high calcium carbonate content (CaCO 3 ) and pH have low fertiliser efficiency, leading to crop deficiency limited productivity. The aim this work was test if acidifying amendments could reduce improve solubility nutrition biomass. Three varying CaCO (14–29% w/w) we...

The taxonomic hierarchy and nationwide distribution of soils with a salic horizon were studied using the USA Natural Resources Conservation Service Soil Survey Geographic (SSURGO) Database to provide a more holistic view of the role of soil-forming factors in pedogenesis than from isolated case studies. Soils with a salic horizon occupied an area of 11 000 km2, i.e., 0.1% of land area in the co...
