Des amendements minéraux et organiques sont appliqués aux sols nouvellement récupérés en Égypte, en particulier les sols sableux et calcaires. Les sols sont très pauvres en matière organique et en nutriments nécessaires aux plantes. Ainsi, l'ajout d'amendements organiques à ces sols améliore non seulement les propriétés physiques et chimiques, mais l'application de ces matières organiques a également un impact positif sur les formes de potassium, en particulier dans les sols sablonneux calcaires. Cette étude vise à évaluer les effets d'application d'un engrais minéral (K2SO4) et de certains amendements organiques (gâteau de boue filtrante, fumier de mouton et fumier de volaille) sur la relation Q/I du sol K et de ses paramètres ainsi que les formes de potassium d'argile et d'huiles calcaires sableuses. Les effets de ces amendements sur certaines propriétés chimiques de ces sols et l'absorption de K par certaines cultures sont également examinés.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Mineral and organic amendments are applied to the newly reclaimed soils in Egypt, especially sandy and calcareous sandy soils. T hese soils are very poor in organic matter and nutrients that are necessary for plants. So, the addition of organic amendments to these soil s does not only improve the physical and chemical properties, but also applying t hese organic materials has a positive impact on the forms of potassium, especially in calcareous sandy soils . This study aims to evaluate the application effects of a mineral fertilizer (K2SO4 ) and certain organic amendments (filter mud cake, sheep manure and poultry manure) on the Q/I relation of soil K and its parameters as well as forms of potassium of clay and calcareous sandy s oils. The effects of these amendments on some chemical properties of these soils and K uptake by some crops are also examined. 176 pp. Englisch. N° de réf. du vendeur 9786200066800
