We assessed the impact of integrated crop-livestock (CL), with silage maize (Zea mays L.) in summerand grazed annual-ryegrass (Lolium multiflorum Lam.) in winter, and continuous crop (CC), with annual-ryegrass used only as cover-crop, on net greenhouse gas emission from soil (NetGHG-S) in a subtropicalFerralsol of a 3.5-year-old experiment in Brazil. Emissions from animal excreta in CL were estimated.Soil N2O fluxes after N application to maize were higher in CL (max. 181 g N2O-N m−2h−1) than in CC(max. 132 g N2O-N m−2h−1). The cumulative annual N2O emission from soil in CL surpassed that in CCby more than three-times (4.26 vs. 1.26 kg N2O-N ha−1, p < 0.01), possibly because of supplementary Napplication to grazed ryegrass in CL (N was not applied in cover-crop ryegrass of CC) and a certain degreeof soil compaction visually observed in the first few centimetres after grazing. The estimated annual N2Oemission from excreta in CL was 2.35 kg N2O-N ha−1. Cumulative annual CH4emission was not affectedsignificantly (1.65 in CL vs. 1.08 kg CH4-C ha−1in CC, p = 0.27). Soil organic carbon (OC) stocks were notaffected by soil use systems, neither in 0?20-cm (67.88 in CL vs. 67.20 Mg ha−1in CC, p = 0.62) or 0?100-cm (234.74 in CL vs. 234.61 Mg ha−1in CC, p = 0.97). The NetGHG-S was 0.652 Mg CO2-Ceqha−1year−1higher in CL than in CC. Crop-livestock emitted more N2O than CC and no soil OC sequestration occurredto offset that emission. Management of fertiliser- and excreta-N must be focused as a strategy to mitigate NO2 fluxes in CL.

Microorganisms associated to plants can promote plant growth and development through direct and/or indirect mechanisms in addition to enabling them to tolerate biotic and abiotic stresses. Several factors are responsible for shaping the microbiome associated with plants and understanding how they influence the structure and functions of microbial communities is crucial for the development of sustainable agriculture. Using culture-independent methods and soils from Rothamsted Research, I will describe the importance of different factors in determining the root microbiome structure and diversity in wheat. In addition, I will describe a culturedependent approach that led to the development of a microbial product for maize. I also discuss gaps and benefits of taking a multidisciplinary approach to explore the plant microbiome to generate microorganism-based solutions for sustainable intensification of crop production. |
