Responses of soil respiration and barley growth to modified supply of oxygen in the soil	2000	16	.pdf	application/pdf	8405	379	69	Responses of soil respiration and barley growth to modified supply of oxygen in the soil Asko Simojoki Department of Applied Chemistry and Microbiology, PO Box 27, FIN-00014 University of Helsinki, Finland, e-mail: asko.simojoki@helsinki.fi Roots of dry-land plants are supplied with oxygen mainly by molecular diffusion from soil air. The strong correlation between ODR measurements and plant performance (Glinski and Stépniewski 1985) emphasizes the impor- tance of an adequate diffusive flux of oxygen from soil air to plant roots.	cache/afs-5671.pdf	txt/afs-5671.txt
