404. Anon.. 1989. Algae: companion crop for reduced compaction.. Journal of Sustainable Agriculture (CA) 2:16..
Soil Technologies Corp. of Fairfield, IA is marketing strains of green algae to reduce compaction and improve soil aggregation. The algae produce polysaccharides which help bind soil particles together. The product Microp is applied in the spring or fall, and must be undisturbed by tillage for 3-4 weeks. Polysaccharides will leach down into the soil. Their field results show a 15% reduction in compaction at 8" depth after the first year. The cost is $6/ac.
