Spatial Variation of Acidic Sodic Soils in High‐Andean Environments and Theoretical Estimation of Gypsum Requirement

Soil Use and Management, Volume 42, Issue 3, July‐September 2026.
ABSTRACT High‐Andean forage systems are characterized by extensive management of cultivated forages, primarily through rotation of forage oats (Avena sativa) and alfalfa (Medicago sativa), under marginal edaphoclimatic conditions. Within this context, soil sodicity severely constrains the productivity of these systems in the districts of Ayaviri and ...

Association of Agro‐Morphological Traits With Cup Quality in Accessions of Coffea arabica L. From the INIA Germplasm Bank, Peru

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 2, June 2026.
ABSTRACT In recent years, Peruvian coffee production has increasingly focused on specialty coffees, with cup quality (CQ) as a key criterion. While previous studies have characterized the Coffee Germplasm Collection of the National Institute of Agrarian Innovation (CGC‐INIA), few studies have analyzed coffee cup quality.

Hindlimb functional morphology and locomotor biomechanics of the small Late Triassic pseudosuchian reptile Gracilisuchus stipanicicorum (Archosauria: Gracilisuchidae)

Journal of Anatomy, Volume 248, Issue 6, Page 1026-1063, June 2026.
A three‐dimensional biomechanical model of the musculoskeletal system is used to analyse the potential locomotor functions of the small (~1 kg) Late Triassic archosaurian reptile Gracilisuchus stipanicicorum. The study finds that, potentially like the ancestral archosaur, this taxon was probably quadrupedal, plantigrade and neither strongly sprawling ...

Innovation Policy in an Emerging Economy: How Regional and Technological Disparities Moderate the Effects of a National Law

Review of Policy Research, Volume 43, Issue 1, January 2026.
ABSTRACT The Innovation Law, enacted in Brazil in 2004, laid the regulatory and institutional foundations for the national innovation system, aiming to promote closer interaction between universities, research institutions, and industry. However, nearly two decades after its implementation, its influence on the national innovation system remains ...

Spatial Assessment of Heavy Metal Contamination in Agricultural Soils of the Lower Chancay–Huaral Valley, Peru

Applied and Environmental Soil Science, Volume 2026, Issue 1, 2026.
Soil contamination by heavy metals (HMs) poses a potential threat to agricultural productivity and food security, particularly in rapidly developing coastal regions. This study evaluates the spatial distribution and contamination levels of cadmium (Cd), copper (Cu), lead (Pb), zinc (Zn), and manganese (Mn) in agricultural soils from the Huaral, Chancay,

Soil Organic Carbon Variability in Tropical Cropping Systems: Interactions With Texture, pH, Macronutrients, and Organic Matter

International Journal of Agronomy, Volume 2026, Issue 1, 2026.
Soil organic carbon (SOC) plays a crucial role in mitigating climate change and enhancing soil fertility. Its storage and dynamics are particularly significant in agricultural ecosystems of the Peruvian Amazon, where the expansion of agriculture and livestock farming may disrupt the regional carbon balance.

Evaluation of Different Types of Aerosols From Wildfires in South America Using Ground‐Based Observations, Reanalysis and CMIP6 Models

International Journal of Climatology, Volume 45, Issue 16, 30 December 2025.
We evaluate MERRA‐2 and CAMS reanalysis products against AERONET observations and compare them with CMIP6 models. CAMS shows better performance in capturing fire‐derived aerosols (BC AOD and OC AOD), with peak values during the dry season (August–October). Both reanalyses capture spatiotemporal AOD variability, although systematic overestimation occurs
