Abstract


The aim of this study is to present the results of the organic technology applied to increase and maintain the biological soil activity in an organic edible rose plantation established within USAMV Bucharest. Before and after planting, three ameliorative species: Sinapis alba L., Phacelia tanacetifolia L. and Tagetes patula L. were sown in seven variants for increasing soil biological activity. Two types of mulches, woodchips and wool, were applied on the rose rows. The results presented statistically significant correlations between different microbiological and agrochemical parameters. A strong correlation between the fungi number and soil respiration (r = 0.94, p<0.05) was observed on the mulched rows. The soil bacteria number was positive correlated with humus content (r=0.68, p<0.05) and negative with mineral nitrogen (r = -0.66, p<0.05). Positive correlation between soil respiration and assimilable potassium content (r = 0.83, p<0.05) was noticed, confirming its role in soil microorganism growth.
