This study (M-TROPICS/BVET) identified and quantified the Si sources to rice plants using a solute mass balance at soil-plant scale and the silicon isotopic signatures of the various Si pools. It reveals that the main Si sources are soil amorphous silica, irrigation water and to a lesser extent Si fertilizer when it was applied. In […]

In montane Southeast Asia, deforestation and unsuitable combinations of crops and agricultural practices degrade soils at an unprecedented rate. Typically, smallholder farmers gain income from “available” land by replacing fallow or secondary forest by perennial crops. The aim of this study (M-TROPICS/MSEC) was to understand how these practices increase or reduce soil erosion. The paper […]
