Short summary
Short summary
Silicon (Si) research could provide complementary measures in sustainably cultivating oil-palm monocultures. Our study shows that current oil-palm management practices and topsoil erosion on oil-palm plantations in Indonesia have caused a spatial distribution of essential Si pools in soil. A lack of well-balanced Si levels in topsoil could negatively affect crop yield and soil fertility for future replanting at the same plantation site. Potential measures are suggested to maintain Si cycling.

We established an oil palm management experiment in a large-scale oil palm plantation in Jambi, Indonesia. We recorded oil palm fruit yield and measured soil CO2, N2O, and CH4 fluxes. After 4 years of treatment, compared with conventional fertilization with herbicide weeding, reduced fertilization with mechanical weeding did not reduce yield and soil greenhouse gas emissions, which highlights the legacy effects of over a decade of conventional management prior to the start of the experiment.

We present results of the Baix loess–palaeosol sequence, SE France. Reconstructed intense soil formation under warm, moist conditions before and into the last ice age and less intense soil formations in warm (temporarily moist) phases during the generally cold, dry ice age were validated with laboratory and dating techniques. This is particularly relevant as Baix is located in the temperate–Mediterranean climate transition zone, a sensitive zone that is susceptible to future climate changes.

Short summary
The central Mongolian forest steppe underlies a recent decline of forested area. We analysed the site and soil properties in the Khangai Mountains to identify differences between disturbed forest areas with and without regrowth of trees. More silty soils were found under areas with tree regrowth and more sandy soils under areas without tree regrowth. Due to the continental, semi-arid climate, soil properties which increase the amount of available water are decisive for tree regrowth in Mongolia.

Short summary
Silicon (Si) can have multiple beneficial effects on crops such as oil palms. In this study, we quantified Si concentrations in various parts of an oil palm (leaflets, rachises, fruit-bunch parts) to derive Si storage estimates for the total above-ground biomass of an oil palm and 1 ha of an oil-palm plantation. We proposed a Si balance by identifying Si return (via palm fronds) and losses (via harvest) in the system and recommend management measures that enhance Si cycling.
