Biodiversity of nematodes biological indicators of soil quality in the agroecosystems
ABSTRACT: Nematodes can be associated with the soil ecological condition, thus being associated with this sustainability condition of agricultural production. Studies of their diversity can be applied with the purpose of using them as bioindicators of environmental changes and the productive impacts...

ABSTRACT: Nematodes can be associated with the soil ecological condition, thus being associated with this sustainability condition of agricultural production. Studies of their diversity can be applied with the purpose of using them as bioindicators of environmental changes and the productive impacts. However, these organisms have been neglected in the agroecosystems, only assuming status of pathogen when their population is very high, with considerable losses in productivity. It is estimated that approximately 10% of the nematodes cause damage to plants, 25% are nematodes grouped into trophic levels of fungivores or fungal feeders, bacterivorous, and omnivores, according to the type of their food. In many cases it is not known the ratio of population level of the nematode with the level of damage in plants. For this reason, the use of pesticides and fertilizers is still part of the most common practices by farmers, causing loss of soil organic matter, soil erosion and groundwater contamination, in addition to an imbalance in the microbiote. The objective of this work was to make a brief review about the diversity of nematodes in the soil in the agroecosystems that can be used in studies of sustainability, as soil quality bioindicators. Several species of nematodes have the potential to be used as biological indicators of soil quality. In this sense, the knowledge and use of bioindicators by rural producers are important, in order to encourage practices of sustainable management systems that do not cause the soil biodiversity imbalance. |
