Phosphorus content of ditch sediments as indicator of critical source areas (Research Note)	2000	5	.pdf	application/pdf	2406	136	66	We compared the extractable P in ditch sediment with the P concentration in ditch water during high flow periods in areas of different land use by assuming that the sediment gradually equili- brates with the water running in the ditch. Dissolved reactive P in ditch water as a function of phos- phorus extracted with ammonium acetate in ditch sediments.	cache/afs-5662.pdf	txt/afs-5662.txt
