Phosphorus release from intact soil monoliths of manure‐amended fields under simulated snowmelt flooding

Autor: Saman Dharmakeerthi, Doug Goltz, Wole Akinremi, Darshani Kumaragamage, Angela Concepcion, S. P. Indraratne

Publikováno v: Journal of Environmental Quality. 50:252-263

Anaerobic conditions developed in soils with flooding can enhance the release of soil P to overlying water, but little information is available for soils with a long history of manure application. We examined the P release from manure-amended soils u

Soil amendments reduce P release from flooded soils: Incubation studies simulating snowmelt and summer flooding

Autor: Doug Goltz, Saman Dharmakeerthi, Darshani Kumaragamage, Emily Van, S. P. Indraratne, U.W.A. Vitharana, Chammi Attanayake, Chamara Weerasekara

Flooding caused by snowmelt runoff in the spring and early summer and heavy rainfall in the summer could enhance P release into nearby surface water bodies causing eutrophication. Six soil amendments were tested for their effectiveness in reducing P

Organic carbon dynamics in soils with pyrogenic organic matter that received plant residue additions over seven years

Autor: Dominic Woolf, R. Saman Dharmakeerthi, Johannes Lehmann, Kelly Hanley, Thea Whitman

Publikováno v: Soil Biology and Biochemistry. 88:268-274

The effect of repeated application of plant residues on mineralization of different organic carbon (OC) pools in a pyrogenic organic matter (PyOM) amended soil was determined using an incubation study conducted over 7.1 years. At five occasions durin
