Grain (agricultural Product)

Historically, tillage has been essential for seedbed preparation and weed control, but it has also accelerated soil degradation through erosion and loss of soil organic matter (SOM). Our objective was to quantify the changes in soil physical properties and earthworm abundance under six tillage treatments on an Endocalcic Chernozem (Loamic) soil (2016 and 2017).
Irrigation management may influence soil greenhouse gas emissions (GHG). Solid-set sprinkler irrigation systems allow to modify the irrigation time and frequency. The objective of this study was to quantify the effect of two irrigation times (daytime, D; nighttime, N)and two irrigation frequencies (low, L; high, H)on soil carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O)emissions in a solid-set sprinkler-irrigated maize (Zea mays L.)field located in NE Spain during 2015 and 2016 growing seasons and the fallow period between growing seasons.
Rising demand for renewable resources has increased silage maize (Zea mays L.)production characterized by intensive soil management, high fertilizer and pesticide inputs as well as simplified crop rotations. Advantages of renewable biomass production may thus be cancelled out by adverse environmental effects. Perennial crops, like cup plant (Silphium perfoliatum L.), are said to benefit arthropods. Substituting silage maize could hence increase biodiversity and foster ecosystem services.
