Availability of nitrogen in solid manure amendments with different C:N ratios

摘要: Manures behave differently as sources of available N due to differences in the amounts and forms manure. The C:N ratio is an important factor affecting rate mineralization release from manures which majority contained organic forms. In order ascertain effect manure on manure-amended soils, 13 solid with a large range were applied two Saskatchewan soils (Haverhill sandy loam Blaine Lake clay loam) at 100 mg kg-1 along control (no manure) treatments. A growth chamber experiment was conducted evaluate relationship between canola yield uptake, laboratory incubation measure how addition different ratios affected pattern measured by supply rates anion exchange membrane (PRSTM) probes placed directly soil. Canola (Brassica napus var. Sprint) grown under ...
