“…Fertilisation rates close to the crop's N demand can result in fertiliser use efficiencies of approximately 50%, as observed by Reddy and Reddy (1993) in the Piedmont region (NC, USA), by Bundy and Andraski (2005) in Illinois, by Normand et al (1997) in France and by Gabriel and Quemada (2011) in Spain. In the last study, it was reported that neither a legume nor a grass cover crop had an effect on the N use efficiency (NUE) with respect to fallow treatment.…”

“…Each microplot received 130 kg N ha -1 as enriched ammonium nitrate (5% 15 N double labelled; Cambridge Isotope Laboratories, Andover, MA, USA), which was applied when the maize had 4-6 leaves (May 23, 2013 andMay 26, 2014). In this study, the established microplots established were larger than in 2007/2009 (Gabriel and Quemada, 2011) and the 15 N richness of the labelled fertiliser was doubled to ensure the solidity of the results. The 15 N fertiliser was applied to the soil surface of the microplot in 4 L of distilled water using a hand sprayer.…”

“…The climate of the area is Mediterranean semiarid (Papadakis, 1966) with a 14.2ºC mean annual temperature and approximately 350 mm average rainfall with high interannual variability. Additional information concerning the soil and climatic conditions can be found in Gabriel and Quemada (2011). Measurements during the experiment of the air and soil temperature, humidity, radiation, PAR (photosynthetically active radiation) and wind were recorded by a CR23X micrologger in a Campbell Scientific station located <100 m from the experiment (Fig.1).…”

“…Cover crops reduce nitrate leaching in many humid (Hargrove, 1991;McCracken et al, 1994;Thorup-Kristensen et al, 2003) and semiarid regions (Salmerón et al, 2010;Gabriel et al 2012b) and they are an important tool to reduce the risk of diffused water pollution (Thorup-Kristensen et al, 2003). Moreover, cover crops increase organic matter (Kuo et al, 1997), water retention capacity (Quemada and Cabrera, 2002), soil aggregate stability (Roberson et al, 1991) and nutrient supply (Gabriel and Quemada, 2011), and the mulch provided by the residue contributes to soil erosion control (Hargrove, 1991).…”

“…Leguminous cover crops do not reduce soil available N at sowing with respect to a fallow treatment (Gabriel and Quemada, 2011); however, non-leguminous cover crops are prone to reducing it (Wagger and Megel, 1988;Thorup-Kristensen, 2001). This could lead to N pre-emptive competition with the main crop, which is often related to microbial immobilization, as reported by Garibay et al (1997) or Kramberger et al (2014) for grasses as cover crops.…”

Cover crop (CC) roots are critical for soil ecosystem service delivery including soil stabilization, C and nutrient cycling, soil health improvement, and others. However, most CC studies only evaluate CC aboveground biomass yield, neglecting the belowground portion of the plant. The objectives of this study were to quantify the impacts of (a) CC planting (pre-and post-harvest) dates and (b) early (2-4 wk before main crop planting) and late (at main crop planting) CC termination with and without corn (Zea mays L.) residue removal on root biomass yield. We assessed the effects of CC planting or termination dates on root biomass yield for surface 10 cm of soil at four sites through sampling at CC termination and separating roots from soil with a hydropneumatic elutriation system. Pre-harvest CC planting had limited and variable impacts on root biomass yield compared with post-harvest planting. Corn residue removal had no impact on root biomass yield. However, CC termination date had effects at the Irrigated but not at the Rainfed site. At the Irrigated site, late-terminated CCs doubled root biomass yield in both years compared to early terminated and no CC. At this site, under late-terminated CCs, root biomass yield was 2.8 Mg ha-1 attributed to their higher aboveground biomass yield and later termination. At the Rainfed site, root biomass yield was 1.6 Mg ha-1. Overall, late termination of CCs can increase root biomass yield; however, early planting into the cash crop did not consistently increase root biomass yield under the conditions of this study. 1 INTRODUCTION Plant roots are critical to the delivery of soil ecosystem services as they directly interact with the soil. Roots influence soil processes and properties more than aboveground biomass (

Harvesting cover crops for biofuel and livestock production: Another ecosystem service?

Harvesting cover crops (CCs) for livestock and biofuel production can be an important ecosystem service from CCs, but this potential service has not been widely discussed. We reviewed the potential use of CCs for livestock or biofuel production, impacts of CC harvesting on soils and crops, the amount of harvestable CC biomass, and strategies to enhance CC biomass production. We searched literature in Web of Science using terms such as “cover crops,” “harvesting,” “soil properties,” and “crop yield,” among others, and found about 30 papers. The literature indicates that CC harvesting does not generally affect soil properties, crop yields, and weed suppression, although the studies are relatively few. Leaving 7.5‐10 cm of CC stubble after harvest could maintain soil ecosystem services. Cover crops produce 3.37 ± 2.96 Mg ha−1 (mean ± SD) of aboveground biomass and 1.33 ± 0.98 Mg ha−1 of belowground (root) biomass. Root biomass input, representing about 30% of the total CC biomass production, could be critical to the maintenance of soil services after CC harvest. The amount of harvestable biomass while maintaining soil services ranges from 1‐3 Mg ha−1 in semiarid regions and from 1‐6 Mg ha−1 in humid regions for high‐biomass‐producing CCs. Strategies to increase CC biomass production include planting CCs early and terminating late, adapting cropping systems by using earlier‐maturity group varieties, and using flexible cropping systems. Overall, CC harvesting appears feasible, but additional research on CC management and harvesting effects on ecosystem services is needed before harvesting CCs at large scales.
