Cowpea (Vigna unguiculata) Water Relations, Growth, and Productivity as Affected by Salinity in Two Soils with Contrasting Mineralogies

Soil Systems
Soil salinity affects crop growth and production, especially in arid and semi-arid regions of the world. The interactions between salt ions and soil particles vary depending on soil texture, mineralogy, and ion composition.

Unravelling upbuilding pedogenesis in tephra and loess sequences in New Zealand using tephrochronology [PDF]

, 2010
The genesis of soils developed in either tephra or loess on stable sites differs markedly from that of soils developed on rock because classical topdown processes operate in conjuction with geological processes whereby material is added to the land ...

Δυναμική του φωσφόρου σε εδάφη alfisols [PDF]

, 2021
Η επίδραση των χρήσεων γης στην αγρονομική και περιβαλλοντική συμπεριφορά των ανόργανων και οργανικών μορφών του φωσφόρου (Ρ), μελετήθηκε σε δυο κατηγορίες εδαφών της τάξης των Alfisols: καλλιεργούμενα εδάφη με διαφορετικά επίπεδα διαθεσιμότητας φωσφόρου (υψηλά, μέτρια και χαμηλά) και εδάφη με φυσική (δασική βλάστηση).

Effect of Chemical Soil Properties on the Growth of Cajuput (Melaleuca Leucadendron (L.) Linnaeus) Stand [PDF]

, 2019
Soil chemical properties play important roles to support plant growth. It determines the nutrient availability which is required by the plant. This study aimed to identify the influence of soil chemical properties on cajuput stand growth.

Zeolite and Organic Fertilizer Application to The Improvement of Available P and Soybean (Glycine max L) Seed Yield in Alfisols

Sains Tanah: Journal of Soil Science and Agroclimatology, 2017
The problem of low soybean yield on Alfisol is low soil fertility. The availability of P is often a constraint because the P element on the Alfisol soil is strongly bound by Al and Fe elements.

INFLUENCE OF ELECTROLYTE ON CADMIUM INTERACTION WITH SELECTED ANDISOLS AND ALFISOLS

Soil Science, 1997
The adsorption-desorption of cadmium (Cd) as a function of pH, ionic strength, and composition of the electrolyte was examined for four variable charge soils: two Alfisols from Zimbabwe (Mazowe and Bulawayo) and two Andisols from Spain (Realejos=l and Realejos=2).
