Arbuscular mycorrhizal fungi (AMF) confer positive and negative effects on many plants, but it is unclear whether AMF has an effect soil fertility, aggregate distribution, stability. The aim of this study was to analyze the Rhizoglomus intraradices plant growth, root morphology, leaf chlorophyll gas exchange, sugar concentrations, nutrients, stability in marigold (Tagetes erecta L.), maize (Zea...

As culturas anuais geralmente são acometidas por doenças causadas fitopatógenos do solo, que prejudicam a produção agrícola gerando perdas econômicas. Entre os mais comuns estão Sclerotinia sclerotiorum, Fusarium sp. e Macrophomina phaseolina. Embora o efeito benéfico de espécies adubação verde em rotação cultura já seja conhecido na proteção fertilidade ainda limitadas as informações proporcio...

Cover crops can improve soil health by maintaining organic carbon (SOC) and nitrogen (N) contents, yet their dynamics in relation to crop yield a semi-arid cropping system are poorly understood. The main objective of this study was evaluate the response diverse winter cover species mixture on SOC N fractions relationship with sorghum (Sorghum bicolor L. Moench) wheat (Triticum aestivum L.)–sorg...

Effects of winter cover crop management on nematode densities associated with a subsequent corn (Zea mays) crop were examined in five sites in north Florida. Two sites had received winter cover crops of lupine (Lupinus angustifolius), and one site each had rye (Secale cereale), hairy vetch (Vicia villosa), and crimson clover (Trifolium incarnatum). In each site, five different management regime...
