Abstract

A study was conducted in the experimental area of INCA, Havana province, on a compacted Red Ferralitic soil. A split plot design with four replications was used in order to evaluate four biofertilization systems in two cropping sequences: soybean (Glycine max L.)-corn (Zea mays)-sweet potato (Ipomea batata L) and soybean-sunflower (Helianthus annus)-sorghum (Sorghum vulgaris). Seeding started in 1998 spring with 32 plots of 100 m2 (10x10 m). Biofertilizer was applied by seed pelletization before sowing. Soybean was inoculated with Bradyrhizobium japonicum (ICA 8001 strain) and Glomus clarum, whereas the remaining crops of each sequence were inoculated with Glomus clarum and Burkholderia cepacia.
For each crop, yield, mycorrhizal colonization and endophyte
weight percentages were evaluated, while soil evaluations were
performed on real density (Dr), bulk density (Da), texture, degree of aggregation, stability coefficient and dispersion index. Results showed a notable influence of biofertilization system and both crop sequences on the degree of aggregation and some indicators of soil physical properties evaluated.
