Maize-bean association in the Amazon

22/10/2025 Go to Evidence

This study evaluates the impact of intercropping maize with native beans on the morphological growth, yield, and nutritional composition of forage intended for silage in the Peruvian Amazon. Treatments between maize monoculture and bean intercropping are compared, as well as different phenological stages (R2, R4, and R5). The results show improvements in protein, fiber, and productive parameters of the forage when intercropped, especially at stage R4 (Alcoser et al., 2025)

Impact of agriculture on forests

19/09/2025 Go to Evidence

The study assesses the impact of converting Amazonian forests to agricultural land in the Peruvian Amazon, analyzing how this transition affects soil organic carbon, total nitrogen, and available potassium. The results show a significant decrease in these essential components, reaching critical levels that compromise fertility, agricultural productivity, and ecological sustainability (Solórzano et al., 2025).

High levels of cadmium in avocado soils in Peru

30/06/2025 Go to Evidence

This study evaluates the spatial distribution of cadmium (Cd) in soils cultivated with avocado (Persea americana) in different regions of Peru, identifying factors that influence its concentration, such as texture, pH, organic matter, and agricultural practices. It was determined that several areas have elevated levels of Cd, which represents a risk to food safety and exports, especially given the European Union's international standards (Solórzano et al., 2025).

Minimum Size for Polygon Geolocation

30/04/2025 Go to Evidence

4 hectares represents the minimum plot size (excluding cattle production) from which geolocation must be provided using polygons with enough latitude and longitude points to outline the perimeter of the land (Sarmiento, 2025).

4 hectáreas representa el tamaño mínimo de parcela (excluyendo producción ganadera) a partir del cual la geolocalización debe proporcionarse usando polígonos con suficientes puntos de latitud y longitud para delinear el perímetro de la tierra (Sarmiento, 2025).

Amazon Basin
