Abstract Micro- and macro-organisms are key components of sustainable soil-plant systems; and are involved in plant growth stimulation and accumulation of heavy metals in the plant, with great contribution to phytoremediation of heavy metal-contaminated soils. Fungi are also producers of antibiotic compounds such as penicillin and cyclosporins. The release of different by-products might change the chemical properties of soil, like the pH, cation exchange capacity, and nutrient content. Aquatic plants (macro- and micro-algae), cyanobacteria, fungi, bacteria, and aquatic animals (shellfish and fish) have an important role in treating various polluted waters. Some organisms are beneficial for the farmers. Mycorrhiza and fungal pathogens also affect seedlings, resulting in harmful consequences for plant population dynamics. Billions of organisms inhabit the upper layers of the soil, where they break down dead organic matter, releasing the nutrients necessary for plant growth. Soil microbes secrete sticky substances such as mucilage and polysaccharides which help in cementing the soil aggregates. The tiny bacteria, termed ultramicrobacteria, can be as small as 0.3 mm in diameter with cell volumes less than 0.1 mm.
