Post‐Fire Soil Organic Carbon Dynamics: Decline and Recovery Over Two Decades

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Wildfire can significantly alter soil organic carbon (SOC) dynamics in forest ecosystems, with complex temporal patterns following fire events. However, research on post‐fire SOC recovery remains limited, particularly in dry‐warm valley regions that are prone to frequent forest fires.

In-Soil Potassium Sensor System

Journal of Agricultural and Food Chemistry, 2004
A potentiometric sensor system based on potassium ion-selective electrodes was developed for agricultural purposes. Sensors were built using PVC ion-selective membranes over an inner solid contact prepared with graphite-epoxy composites. A copper plate was used as a reference electrode.

Potassium Dynamics in Soils

2021
Potassium (K) is a macronutrient required by plants in larger amounts such as nitrogen, however, different from all macronutrients because of its specific retention in the soils. It is a structural part of most of the soil minerals and its availability to plants is not directly proportional to the total amount of K in the soils.
