afs-71941	Haman, František	Effects of percolating water with graduated acidity upon the leaching of nutrients and the changes in some chemical properties of mineral soils 	1977	8	.pdf	application/pdf	3120	152	61	It should be mentioned that this effect de- pends also upon the clay content of the soil, since in soil A (fine sand) the acidification was more significant than in soils B (loam) and C (clay loam). In soil C (clay loam) there was an apparent tendency for the con- centration of nitrates in extracts to decrease with the increasing acidity of percolating water.	cache/afs-71941.pdf	txt/afs-71941.txt
