I'll Be Dammed: Efficiency and Cost‐Analysis of a Rehabilitated Prehispanic Dam in the Andes

Geoarchaeology, Volume 41, Issue 4, July/August 2026.
ABSTRACT Within archaeology there is a growing shift away from the purely aesthetic towards making the past relevant to present and future needs and demands. The Past Water Futures project charts the impact of ancient dam rehabilitation on climate change‐induced water scarcity in the North Central Andes.

Zoning of a Newly-Planted Vineyard: Spatial Variability of Physico-Chemical Soil Properties

Soil Systems, 2020
Soil properties show a high spatio-temporal variability, affecting productivity and crop quality within a given field. In new vineyard plantations, with changes in the initial topographic profile, this variability is exacerbated due to the incorporation ...

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 ...

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.
