Effect of Organic and Mineral Soil Additives on Asparagus Growth and Productivity in Replant Soils

The repeated cultivation of asparagus in the same field can severely reduce yield. A complex predominantly microbial causes is suspected. Limited plant development, establishment problems, and yield loss may occur, particularly light sandy soils. In order to address this replant problem evaluate alternative conditions, two fields were treated with different supplements cultivated for 5 years investigate their impact on results from pot trials using soils these are presented, along trial findings. included incorporation mushroom substrate (champost), Fimonit (clay mineral), mustard meal (biofumigation), Micosat F Uno (including arbuscular mycorrhizal fungi, Trichoderma viride, rhizosphere bacteria species). trials, sterilised soil exhibited a growth benefit over original soil. However, tested additives had no significant effects short period 8 weeks. At one sites, marketable yields following champost, Fimonit, biofumigation, treatments 14, 6, 16 12% higher than that control soil, respectively, but differences treatment effect observed second test field. Biofumigation champost was most successful reducing replanting yields.
