Silicon (Si) speciation and availability in soils is highly important for ecosystem functioning,
because Si is a beneficial element for plant growth. Si chemistry is highly complex compared …

Our current understanding of silicon (Si) availability in agricultural soils is reviewed and
knowledge gaps are highlighted. Silicon is a beneficial rather than essential plant nutrient …

Plants' ability to take up silicon from the soil, accumulate it within their tissues and then
reincorporate it into the soil through litter creates an intricate network of feedback …

Rock powders are low-cost potential sources of most of the nutrients required by higher
plants for growth and development. However, slow dissolution rates of minerals represent …

Carbon sequestered in phytoliths, the silicified features of plants, may accumulate in soils
and sediments for several hundreds to thousands of years depending mainly on the …

Terrestrial enhanced weathering is the spreading of silicate powder on land, and can
sequester atmospheric CO 2 through carbonation of calcium-and magnesium-rich minerals …

Silicon (Si) is beneficial to plants since it increases photosynthetic efficiency, and alleviates
biotic and abiotic stresses. In the most highly weathered and desilicated soils, plant …

Aims Supplying phytolith-rich biochar in agrosystems increases soil pH, CEC and nutrient
availability, adding to the impact of Si uptake on plant growth. Here we studied this specific …

Salinity has emerged as a major threat to food security and safety around the globe. The
crop production on agricultural lands is squeezing due to aridity, climate change and low …

Carbon dioxide (CO2) is a major greenhouse gas, and its concentration in the atmosphere is
increasing continuously, hence there is an urgent need to reduce its level in the atmosphere …
