Among the soil organisms that are pests of crops are nematodes, slugs and snails, symphylids, beetle larvae, fly larvae, caterpillars, and root aphids. In the ecosystem, nutrients exchange between living and nonliving parts. For example, root-knot nematodes can damage plant roots, and fungi can cause root rot. Addition of nitrogen in the soil by bacteria is called bacterial-fertilizers. However, they have some challenges that have hindered their extensive and successful use. ; Moreno, S.; Salerno, G.L. The soil, where the interactions between the plant and the environment occur, needs to have enough quality to ensure good development and growth of the plant. Nematodes are often talked about in a quiet fearful voice. Soils are some of the most complex ecosystems on Earth, containing nearly a quarter of the planet's biodiversity. This may adversely affect growth in two ways: The minimum amounts of oxygen necessary for the respiration of the root would not be available. Blue-green algae is capable of fixing atmospheric nitrogen to the soil. The conversion of elemental nitrogen to readily available form by nitrogen-fixing microorganisms is called biological nitrogen- fixation. Visit our dedicated information section to learn more about MDPI. Increasing soil capacity and containing organic matter and nutrients will also help to stimulate the growth of microorganisms. As soils interact with the atmosphere, their complex boundary to the environment is also visible. Another type of nematode that can be beneficial to farming systems is the insect-parasitic bacterial feeding nematode. the editor(s) disclaim responsibility for any injury to people or property resulting from any ideas, Corrections?
