Organic viticulture and soil quality: A long-term study in Southern France
2011年10月1日 · Michaud et al. (2007) have shown that in calcareous soils contaminated by Cu fungicides, water-extractable Cu varied little, compared to total soil Cu, or EDTA-extractable Cu. Generally, grass cover and applications of organic matter have positive effects on earthworms in vineyards (Peres et al., 1998, Paoletti, 1999, Eisenhauer et al., 2009 ...
Solution and associated features of limestone fragments in a calcareous …
1985年11月1日 · Three pedological features, associated with hard, residual fragments of limestone from a calcareous soil profile from southern France, have been observed and analysed in thin sections. There are corrosion pits and galleries in the fragments, amorphous and iron-rich films on the surfaces of the fragments, and calcium oxalate (weddellite ...
Distribution, characteristics and management of calcareous soils
2023年1月1日 · Calcareous soils cover a large percentage of the north coastal regions of Africa. In South Africa, calcareous soils are mostly distributed in the drier western and northern parts of the country, with small patches in the south-western Cape Province (Mediterranean climate) and eastern parts of the country (Fey, 2010). As per Egypt's Ministry of ...
Function of Soils for Human Societies and the Environment
The ‘Massif de La Clape’ in Southern France is a calcareous hill with a semi-arid Mediterranean climate. All the agricultural lands are under vineyards managed by different châteaux.
EGQSJ - Reconstructing the Eemian to Middle Pleniglacial ...
2024年1月9日 · We present results of the Baix loess–palaeosol sequence, SE France. Reconstructed intense soil formation under warm, moist conditions before and into the last ice age and less intense soil formations in warm (temporarily moist) phases during the generally cold, dry ice age were validated with laboratory and dating techniques.
Main water pathways in cultivated clayey calcisols in molassic hills …
2023年7月31日 · In this paper, we analyze soil data and hydrological monitoring, with the aim of conceptualizing the typical water flow paths of clayey calcisols in the molassic hills of southwestern France. We identify the areas where the waterlogging risk is the highest.
(PDF) Calcareous microbialites and associated biota in the ...
2015年1月1日 · Microbialites were found in various lagoons of the Mediterranean coast of southern France. They preferentially develop on pebbles on the edge of semi-enclosed water bodies, which can be...
Soil calcium carbonate (CaCO3) impacts plant mineral nutrition far beyond Fe metabolism, imposing constraints for crop growth and quality in calcareous agrosystems. Our knowledge on plant strategies to tolerate CaCO3 effects mainly refers to Fe acquisition.
Growing on calcareous soils and facing climate change
2024年4月2日 · Soil calcium carbonate (CaCO 3) affects plant nutrient acquisition and consequently shoot mineral homeostasis leading to chlorosis and yield losses in maladapted crops. Different tolerance strategies have been identified, notably Ca flux regulation, biomineralization, and secretion of root exudates to remobilize unavailable soil nutrients.
GlobalSoilMap France: High-resolution spatial modelling the soils …
2016年12月15日 · The more basic pH corresponded to calcareous materials (Southern France, Lorraine, Champagne, Cognac) and the neutral pH corresponded to deep loamy or clay intensively cultivated soils (Northern France, Southwest France). See Supplement G for the geographic location of these regions.
