Agricultural systems in Amazonia depend on the management of mycorrhizal fungi. Repositório Alice
FELDMANN, F.; IDCZAK, E.; NUNES, C. D. M..
A large number of useful tropical plant species are dependent on mycorrhizal fungi. Without the fungal symbionts they show growth depression and lower tolerance to biotic and abiotic stresses. In plant production systems, common management practices normally result in symbiosis deficits. In tropical regions where the system of shifting cultivation is practiced, the fallow period was thought to have a positive regulating effect on the mycorrhizal situation. It's showed that between three and eight years of fallow there is an increase of the inoculum potential in the soils but the effectivity of the fungal populations remains very low in comparison to the populations from natural sites. The need to manage the mycorrhizal fungi in situ in the field is...

Isolation, selection and production of vesicular-arbuscular mycorrhizal fungi (VAMF) and their application in mixed cropping systems. Repositório Alice
FELDMANN, F.; MULLER, I.; WERITZ, J.; MACEDO, J. L. V. de; IDCZAK, E..
The introduction of VAMF into agricultural systems benefits the growth and the health of the crops, especially in abandoned areas with poor soils. As a pre-requisite for the application of the symbiots, the fungi must be isolate and selected with respect to their efficiency for the plants and their adaptability to the environmental conditions in the field. Different methods of isolation and the selection procedure are described. The mass production of the selected fungi can be carried out in the greenhouse or in the field. The inoculation of the plants with the VAMF is possible in the nurseries as well as in the field. Two methods of application - inoculation of the plants with a homogenous mixture of the inoculum in the substrate and with a concentrated...

Production of urucum (Bixa orellana L.) inoculated with by micorrhizal fungi in mixed cultivation systems. Repositório Alice
NORMANDO, M. C. S.; IDCZAK, E.; MARTINS, G. C.; MACEDO, J. L. V..
The urucum seedlings were inoculated with VA-mycorrhizal fungi in the nursery, on non-sterilized substrate. Root colonization in the nursery before planting into the field was statistically higher for inoculated plants (59% + ou - 11%) than for non-inoculated plants (31% + ou - 20%). After some time in the field, root colonization was the same in the different treatment regimes. However, the highest percentage colonization was found in the plants which received only 30% of the recommended fertilizer dose. The plant height in the different treatment regimes did not differ statistically. There was a significant difference in stem diameter between the two fertilization levels, but the stem diameters of the inoculated and non-inoculated plants were the same...

Recultivation of abandoned monoculture areas in Amazonia. Repositório Alice
LIEBEREI, R.; GASPAROTTO, L.; PREISINGER, H.; FELDMANN, F.; IDCZAK, E..
The project concerns an experiment in recultivating a fallow rubber plantation of 19 ha by establishing mixed plantations of selected crops, mainly tree. In order to achieve sustainability, different crop combinations and different strategies for management of the spontaneous vegetation will be tested, and the crop systems will be stabilized by inoculation the plants with spores of mycorrhizal fungi. The experimental area was divided into five blocks with eighteen plots each to test four mixed cultivation systems, compared to four conventional monoculture systems. Fallow plots will be analyzed for reference. The scientific research is focused on the ecological role of mycorrhizal fungi in the field trial, analysis of the structural and functional traits of...
