Abstract The application of mechanically crushed silicate minerals to agricultural soils has been proposed as a method for both improving crop yields and sequestering inorganic carbon through enhanced mineral weathering. In Greenland, large quantities finely grained glacial rock flour (GRF) are naturally produced by erosion bedrock deposited in easily accessible lacustrine marine deposits, without the need energy-intensive grinding. To determine if this material can improve yields, we...
Abstract Rock flour (RF) is a fine‐grained material produced naturally by glacial movement and resulting bedrock abrasion. In Greenland fluvial transported RF from the inland ice sheet sediments in riverbeds marine outflows. This fine‐sized (50% < 9.8 µm) has high reactivity may therefore potentially be used to rejuvenate nutrient poor soils provide nutrients plants. The aim of this study was evaluate ability supply P, K, Mg, S A double‐pot system used, which ryegrass ( Lolium perenne L...
Phosphorus (P) is critical for food production. However, it has been managed unsustainably decades and geopolitical challenges complicate its availability. While accessible P-rock deposits are linearly exploited, excessive fertilization practices lead to P loss from land water, thus, eutrophication. The release of legacy sediments the water column, i.e. internal loading, sustains global eutrophication issues. Sediment removal subsequent reuse as soil amendment can simultaneously lower...
Biochar pellets produced from the solid fraction of manure-based digestates are rich in phosphorus (P) and may represent a P source that is easy to handle suitable for transport P-deficient regions. However, effect feedstock composition particle size on availability this type biochar remains unexplored. To evaluate short-term biochars derived manure digestate solids, an incubation experiment was carried out, which four solids powder pellet form were incubated with three soils low content....
