Trichoderma Mobilizes Phosphorus and Cobalt While Excluding Sodium in the Foliar Ionome of High‐Andean Grasses Enriched With Biochar

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 3, September 2026.
This graph shows how guinea pig manure biochar raises the pH in high‐Andean soils (4150 m). Although biochar improves soil quality, nutrient uptake depends on the microorganism: Trichoderma sp. alters the foliar ionome by increasing P and Co and excluding Na, while micronutrients maintain their homeostasis depending on the species. ABSTRACT Acidic high‐

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 ...

Volcanic Ash Weathering and Pedogenesis in Mount Penanjakan: Soil Evolution Supporting Pioneer Vegetation [PDF]

E3S Web of Conferences
Volcanic ash deposits play a fundamental role in soil formation processes and the establishment of pioneer vegetation in highland ecosystems. This study investigates soil evolution and pedogenesis derived from volcanic ash in Mount Penanjakan, Bromo ...

Transformer‐Based Digital Soil Mapping Reveals Land‐Use Legacy Effects on (Sub)Tropical Soil Carbon

Earth's Future, Volume 14, Issue 9, September 2026.
Abstract Tropical and subtropical soils store approximately one‐third of global soil organic carbon (SOC) despite covering less than one‐quarter of terrestrial surfaces, yet accurate spatiotemporal prediction methods remain inadequate. We present the first application of transformer architectures to multi‐temporal Landsat observations for SOC ...

KURVA SORPSI FOSFAT MENURUT LANGMUIR DAN FREUNDLICH SEBAGAI PENDUGA KEBUTUHAN PUPUK FOSFAT PADA ANDISOLS SUMATERA BARAT [PDF]

, 2014
Andisols are among the most productive soils in the world, but these soils also strongly retained phosphate. The high capacity for phosphate sorption in Andisols is due to their high content of active Al and Fe compounds.

Soil Transition and Characteristics Along a Periglacial–Agricultural Gradient in the Carihuairazo Volcano Area

Earth
Climate change and glacial retreat in the tropical Andes—as evidenced by environmental changes in the Carihuairazo volcano area and human-induced alterations to the páramo—reveal complex environmental dynamics that require an integrated understanding ...

Five decades of hand‐feel soil texture estimation: Accuracy, challenges, and improvements

Soil Science Society of America Journal, Volume 90, Issue 3, May/June 2026.
Abstract Soil texture refers to the proportion of fine soil particles with diameters less than 2 mm, classified into particle size categories that define the soil texture class. Hand‐feel estimation in the field is widely used by soil scientists and technicians during pedological surveys to characterize soil horizons.

Compost legacy effects in active roadside restoration: Medium‐term shifts in plant succession

Ecological Solutions and Evidence, Volume 7, Issue 2, April–June 2026.
Roadside restoration experiment established on volcanic tephra following road construction in Andean Patagonia. A single application of municipal (MC) or biosolids (BC) compost rapidly increased plant cover compared with untreated controls (C) but led to distinct, exotic‐dominated plant communities over 6 years.
