“…OF NUTRIENT COMPETITION AND SOIL RECEPTIVITY Two parameters determine the intensity of competition for a given nutrient : the amount of the nutrient available and the amount (total mass) of microorganisms capable of using this nutrient at the time it becomes available. To evaluate the biomass and total microbial activity of suppressive and conducive soils, we studied their respiratory response to glucose supply (ALaBOUVETTE et al, 1985b). It is clear that the initial respiratory rate, which reflects the total microbial biomass (ANDERSON & DotvtscH, 1978), is 3 to 4 times greater in suppressive than in conducive soil (fig.…”

“…Au cours de travaux précédents, nous avons démontré que la germination des chlamydospores et le développement saprophytique des Fusarium spp. nécessitent un apport d'énergie plus important dans le sol résistant de Châteaurenard que dans le sol d'Ouroux (ALaBOUVETTE et al, 1985). Ces résultats ont été interprétés par rapport aux phénomènes généraux de fongistase et de compétition nutritive qui, dans tous les sols, contrôlent la mise en activité des organes de conservation et le développement des microorganismes (L O C KW OO D , 1981).…”

“…Conversely, if we consider three, rather than two, mineral elements, the mineral balance least favourable for the development of foot rot in wheat, both in seedlings and in adult plants, is high levels of nitrogen and potassium and low levels of phosphorus [128]. solani favours the germination of these spores and the development of their germination tubes [131]. A similar result was also reported in a previous study: wheat root exudates increase the number and length of germination tubes arising from the spores of F. roseum and M. nivale [98].…”
