Glacial rock flour reduces the hydrophobicity of Greenlandic cultivated soils
Soil water repellency (WR) is ubiquitous across Greenlandic cultivated fields, which may constrain agricultural production. Fine-grained glacial rock flour (GRF) is available in the surrounding landscape, which could serve as a soil amendment. We tested whether the application of GRF (rates of 0, 50...

Soil water repellency (WR) is ubiquitous across Greenlandic cultivated fields, which may constrain agricultural production. Fine-grained glacial rock flour (GRF) is available in the surrounding landscape, which could serve as a soil amendment. We tested whether the application of GRF (rates of 0, 50, 100, 300, and 500 ton ha −1 ) reduced the WR across two field trials in South Greenland. The field trials, Upernaviarsuk (UP) and South Igaliku (SI), differed in clay (UP: 0.05–0.11 kg kg −1 SI: 0.03–0.05 kg kg −1 ) and organic carbon (OC) contents (UP: 0.04–0.13 kg kg −1 SI: 0.01–0.03 kg kg −1 ). We measured WR across gravimetric water contents (W) from oven-dry to the W where WR ceased (W NON ) to obtain whole WR-W curves. Most soils became hydrophilic around air-dry conditions at application rates of ≥300 ton ha −1 , likely due to increased clay:OC ratios.
