Abstract:
The effect of soil inoculation with urea, Nostoc muscorum, and Tolypothrix tenuis on rice seedlings, nutrient contents, and structure of postharvest soil was studied. Tolypothrix tenuis and T. tenuis + urea produced the highest increase in oxidizable C (54.60% both) which resulted 7.63% higher than urea. Tolypothrix tenuis also produced the highest increase in soluble C (241.14%). Regarding nitrogen (N) soil content all treatments produced a positive difference. No treatment exerted any effect on soil available phosphorus (P). The percentage of aggregates >50 (m increased with all treatments from 6 to 12%, except N. muscorum. Tolypothrix tenuis produce the highest effect, with 50% more of these aggregates than urea. Seedling dry weight and shoot length were higher than control for all treatments. Shoots were longest with N. muscorum + urea being this treatment more effective than each Cyanobacteria alone. There was no effect on the number of leaves. Except for N. muscorum, all treatments increased the seedling N content. Postharvest soil showed a better quality when inoculated with T. tenuis or T. tenuis + urea compared to urea. Cyanobacterial fertilizers are a promising alternative to avoid soil pollution caused by agrochemicals and recover the nutrient content and structure lost after harvest as they bring to soil combined N (some of them are N fixers), exopolysaccharide that improve soil structure and bioactive substances that enhance seedlings growth.
