Lime and calcium-magnesium silicate in the ionic speciation of an Oxisol

, 2017
Plant residues and certain fertilizers accelerate soil acidification and increase the levels of aluminum-Al+3 in soils under no-tillage (NT). Silicates act as acidity amendments and as a source of silicon as in H4SiO4.

Yield, stability, and plasticity of Arabica coffee genotypes under contrasting pruning systems

Agronomy Journal, Volume 118, Issue 3, May/June 2026.
Abstract Coffee yield instability caused by biennial bearing causes coffee yield instability, reducing production predictability and farm income. Biennial drastic pruning (Zero Crop), which alternates harvest and no‐harvest years, has been proposed to reduce this instability, but its benefits depend on genotype performance under contrasting management.

Mammals' zoogeochemical effects change litter and soil biogeochemistry in a tropical rainforest

Ecological Monographs, Volume 96, Issue 2, May 2026.
Abstract While most research on nutrient cycling has focused on plant–soil interactions or soil decomposers, recent studies highlight the emerging role of terrestrial mammals in contributing to biogeochemical cycles, a field known as zoogeochemistry. More than half of all mammal species are found in tropical forests, ecosystems currently experiencing ...

Release of Andean abiotic‐resilient common bean germplasm

Journal of Plant Registrations, Volume 20, Issue 2, May/August 2026.
Abstract Andean abiotic‐resilient (AAR) common bean (Phaseolus vulgaris L.) germplasm lines AAR1 to AAR7 were developed through an international bulk breeding effort to improve abiotic stress tolerance and combine it with disease resistance by increasing genetic richness.

Agroforestry and enhanced rock weathering: A dual strategy for sustainable cacao

PLANTS, PEOPLE, PLANET, Volume 8, Issue 3, Page 843-860, May 2026.
Cacao production is both economically vital and environmentally intensive, presenting a major sustainability challenge as a crop largely cultivated by smallholder farmers in climate‐vulnerable regions. This review synthesises evidence that integrating agroforestry with enhanced rock weathering (EW) may significantly reduce emissions from cacao ...

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.

Nutrient Leaching in a Colombian Savanna Oxisol Amended with Biochar [PDF]

Journal of Environmental Quality, 2012
Nutrient leaching in highly weathered tropical soils often poses a challenge for crop production. We investigated the effects of applying 20 t ha biochar (BC) to a Colombian savanna Oxisol on soil hydrology and nutrient leaching in field experiments. Measurements were made over the third and fourth years after a single BC application. Nutrient contents

Micronutrients for cacao: Availability classes in two soil layers

Soil Science Society of America Journal, Volume 90, Issue 3, May/June 2026.
Abstract Efficient management of soil micronutrients is crucial for the yield and sustainability of cacao (Theobroma cacao L.), especially in tropical regions. However, specific availability classes for copper (Cu), iron (Fe), manganese (Mn), and zinc (Zn), extracted by Mehlich‐1, had not yet been established for the crop in Brazil. This study presents,

Soybean yield performance in oxisols with varying morphological and physicochemical characteristics

Soil Science Society of America Journal, Volume 90, Issue 3, May/June 2026.
Abstract Soybean (Glycine max (L.) Merril) yield in tropical high‐altitude regions is strongly influenced by soil physical and chemical attributes, particularly in highly weathered oxisols, where variability among suborders may affect crop performance.

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 ...
