Effect of forestation on soil fungitoxicity
1974
HORA, F. K. | KO, W. H.
Ascospores of Neurospora tetrasperma germinated on topsoils of forest but not agricultural Hydrol Humic Latosols (Hydrendept). All the agricultural and some of the forest subsoils were inhibitory to spore germination. There was no correlation between pH or organic matter content and spore germination on soils. Results showed that all the major plant species in the forest accumulated a higher concentration of Al from soil than the sugar cane on the agricultural land. The biomass of the total forest plants also was much greater than that of the sugar cane. It is postulated, therefore, that effective accumulation of free Al ion from soil by forest plants results in decrease of fungitoxicity in forest soils.
