Sustaining Cocoa Production on Oxisols in Malaysia [PDF]

, 2015
Oxisols are dominated by variable charge minerals in their clay fraction, containing an insufficient amount of Ca and Mg in their soil solutions. Under natural conditions, cocoa grown on the soils is subjected to the stress of low pH and Al and/or Mn toxicity, which eventually produces low yields.

Nickel Effects on Growth and Phytolith Yield of Grasses in Contaminated Soils

Soil Systems
Nickel (Ni) is extremely toxic to plants at high concentrations. Phytoliths have the potential to sequester the heavy metals absorbed by plants and act as a detoxification mechanism for the plant.

Impact of Seasonal Waterlogging on Organic Carbon Stabilisation and Microbial Communities in Cultivated Mineral Soils

European Journal of Soil Science, Volume 77, Issue 4, July/August 2026.
ABSTRACT Waterlogging of aerobic soils can induce microbially catalysed reductive dissolution of iron oxides and the subsequent mobilisation of associated carbon. Additionally, the resulting shift in microbial metabolism and community structure may eventually affect the accrual of microbially derived carbon into soils.

STRUCTURAL QUALITY INDICATORS IN COMPACTED OXISOLS GROWN WITH CORN

REVISTA DE AGRICULTURA NEOTROPICAL, 2020
In the face of the elevated cost of economic and environmental order to recover degraded soil, the monitoring of the structural quality of the soil through physical and plant indicators is recommended. This way, this work aimed to verify which parameters may be used together with soil penetration resistance (PR), after compression induced by ...

Establishment and Yield of Overseeded Black Oat in a Silvopastoral System: Effects of Tree‐Induced Changes in Microclimatic and Soil Conditions

Grass and Forage Science, Volume 81, Issue 3, July-September 2026.
ABSTRACT Tree integration into pasture systems modifies microclimatic and edaphic conditions that can influence forage dynamics, especially during the establishment of overseeding annual cool‐season forage species in subtropical regions. This study evaluated the agronomic performance of black oat (Avena strigosa), overseeded into a warm‐season ...

Leaf Fungal Microbiome Is Modulated by Interspecific Hybridization Events Between Coffea Species

Physiologia Plantarum, Volume 178, Issue 4, July/August 2026.
ABSTRACT Increasing attention has been given to the host phylogeny and domestication roles in shaping plant‐associated microbiomes. However, the interspecific effects of hybridization on microbial communities remain poorly understood. We investigated the effects of interspecific hybridization on the composition, diversity, ecological organization, and ...

Cambios en el contenido de fósforo en el suelo superficial por la conversión de sabanas en pinares Changes in phosphorus content in the topsoil by the conversion of savanna to pine forest

Bioagro, 2005
Se evaluaron los cambios en fracciones de P, la actividad de fosfatasas ácidas y la adsorción de fosfatos producidos por el establecimiento de una plantación de pinos en suelos de sabanas, ácidos y arenosos. Luego de 24 años, se encontró un incremento en
