Synthesis of a National Soil Dataset Across Productive Land in Mexico: The Importance of Making Existing Data Accessible

open access: yesEuropean Journal of Soil Science, Volume 76, Issue 3, May–June 2025.
ABSTRACT The lack of soil data is a complication that most soil scientists will encounter throughout their career; this critical aspect is exacerbated due to the excessive cost of soil surveying. Consequently, it is essential to develop strategies that guarantee the permanent accessibility of past soil sampling efforts.

Interacción de cuatro minerales de la arcilla con ortofosfato dicálcico dihidrato

open access: yes, 1970
[EN]: The use of dicalcium phosphate dihydrate contained in dialytic bags allow this solid to react with clay minerals and demonstrate that the phosphate fertilizers in contact with enough water transforms themselves. When the pH of the systems is lower than 7 the dicalcium phosphate dihydrate transforms to octacalcium phosphate if there is not ...

Estimates of Soil Organic Carbon in the Ojos de Agua and El Quinillal Forests in the Central Huallaga of Peru

open access: yesInternational Journal of Forestry Research, Volume 2024, Issue 1, 2024.
The Peruvian Amazon has experienced large losses of forest cover due to changes in land use, contributing to increases in CO2 in the atmosphere. This study estimated the organic carbon content of forest soil in two forests “Ojos de Agua” and “El Quinillal” in the Central Huallaga of Peru, establishing three types of cover: (i) primary, (ii) intervened,
