In the project MaisSolo, a consortium comprising growers, farmers&#8217; associations, researchers and academia, we aimed to demonstrate that the introduction of cover crops will help to improve soil structure and soil water properties (water infiltration and retention), enhance nutrient recycling and reduce agrochemical needs, with impact on pests and diseases cycle break. Nematodes inhabit all type of soils and are often used as soil status bioindicators. In this work, the evaluation of nematode communities was used to assess the effects on soil status of the proposed alternative practices: 1) biodiverse mixture of grasses and legumes 2) annual ryegrass and 3) biofumigation (forage turnip). In the control plot no cover crop was set. At the end of the 4-year experimental period, the number of free-living nematodes increased in all treatments compared with the control plot, namely the bacteriophagous group, in the mixture treatment, indicating an improvement in the organic matter content of each plot.]]></p></abstract>
<abstract abstract-type="short" xml:lang="pt"><p><![CDATA[Resumo Os sistemas de produção intensivos hortoindustrais do Ribatejo (centro de Portugal) baseiam-se no recurso à monocultura e num elevado grau de intervenções culturais. O projeto MaisSolo, um consórcio formado por agricultores, associações de produtores, investigadores e a academia, teve por objetivo demonstrar que a introdução de culturas de cobertura contribui para a melhoria da estrutura do solo e da sua capacidade de retenção da água, melhorando a reciclagem de nutrientes e reduzindo a necessidade de agroquímicos, com impacto positivo na diminuição da prevalência de pragas e doenças. Os nemátodes, pequenos animais que habitam em todos os tipos de solo, são cada vez mais usados como bioindicadores do status do solo. Neste projeto, efetuou-se a avaliação das comunidades de nemátodes presentes em solos sujeitos a diferentes tratamentos: 1) consociação de leguminosas e gramíneas; 2) azevém anual e 3) biofumigação. Na parcela de controlo não se instalou qualquer cultura de cobertura. No final do período experimental (4 anos: 2017-2021), as populações de nemátodes de vida livre no solo aumentaram em todos os tratamentos comparativamente às parcelas de controlo, nomeadamente dos nemátodes bacteriófagos, o que indica uma melhoria do teor de matérias orgânica em cada um dos talhões, sobretudo naqueles com instalação de consociação.]]></p></abstract>
