“…Second harvest productivity was 20% higher because its growing was subjected to a larger photoperiod of year (February to May), besides being irrigated. Due to the high levels of productivity, the values of output energy (1,143.8 and 1,330.9GJ ha -1 ) were much higher than reported by other authors (ZANINI et al, 2003;KOMLEH et al, 2011;MARTINS et al, 2015;LIN et al, 2016).…”

“…However, productivity was significantly lower, resulting in an energy efficiency of 9.69 (spacing of 0.6m). LIN et al (2016), in turn, showed an energy efficiency of 20.4 and 33.5 for maize silage in conventional farms and for agroforestry systems, respectively.…”

“…According to the soil fertility analysis, the recommended dosage of NPK was smaller in the second harvest, which reduced the demand of fertilizers. Several authors that performed the energy balance of maize crop for grain and silage presented the fertilizers as the main input of energy consumption (CUNHA et al,2015;MARTINS et al,2015;VEIGA et al,2015;LIN et al,2016;FERRO et al,2017).…”

“…The authors MARTINS et al (2015) and LIN et al (2016), which did not consider irrigated crops, obtained an output energy of 140.1 and 345GJ ha -1 , for the first and second harvests respectively. Both authors adopted values for energy coefficients similar to the ones presented in this study ).…”

The aim of the present study is to evaluate the energy balance and energy efficiency of the silage maize crop in the Center for Research, Development and Technology Transfer of the Universidade Federal de Lavras (CDTT-UFLA). The crop was irrigated by center pivot and the stages of maize cultivation and energy inputs were monitored for the 1st and 2nd crops of the 2014/2015 harvest. Results from the energy analysis showed the crop had a total energy input of 45,643.85 MJ ha-1 and 47,303.60 MJ ha-1 for the 1st and 2nd crops and a significant predominance of direct energy type (about 92% of the matrix). Regarding direct energy inputs, the diesel oil was the most representative, contributing with approximately 38% of the total energy demand. Conversely, the irrigation system contribute with 3.92% e 5.97% in the 1st and 2nd crops, representing the largest indirect energy input. Nevertheless, irrigation and crop management allowed the system achieving high levels of productivity, resulting in an energy efficiency of 25.1 and 28.1 for the first and second crops respectively.

“…This analytical disarray is aggravated by the fact that (a) researchers apply different, selective, and independently developed categories of classification systems for soil functions (Blum, 2005;FAO & ITPS, 2015;Stavi et al, 2016), and (b) different available ecosystem service classification systems exist (Haines-Young & Potschin, 2013;MEA, 2005;TEEB, 2010). Likewise, a conceptual study that directly connects soil function to services and that proposes a differentiation between both concepts is hard to find (an exception is,e.g., Pulleman et al, 2012, investigating soil biodiversity Li et al, 2013;Miklovicova & Miklovicova, 2012;Moreau et al, 2012;Rehman et al, 2011;Spicka, 2015Moreau et al, 2012Phengphaengsy & Okudaira, 2008;Rehman et al, 2011;Steyn et al, 2016;Zhao et al, 2010 Energy Alluvione, Moretti, Sacco, & Grignani, 2011;Deike, Pallutt, & Christen, 2008a;Deike, Pallutt, Kustermann, & Christen, 2008b;Giambalvo et al, 2009;Khakbazan et al, 2017;Lin et al, 2017;…”

Managing soil functions for a sustainable bioeconomy—Assessment framework and state of the art

Bioeconomy strategies have been adopted in many countries around the world. Their sustainable implementation requires a management of soils that maintains soil functions and avoids land degradation. Only then, ecosystem services can be maintained and resources used efficiently. We present an analytical framework for impact assessment that links policy and technology driving forces for soil management decisions to soil processes, soil functional changes, and their impacts on ecosystem services and resource use efficiency, both being targets that have been set by society and are anchored in bioeconomy policy strategies and sustainable development goals. Although the resource use efficiency concept has a long-term tradition, most studies of agricultural management do not address the role of soils in their efficiency assessment. The concept of ecosystem services has received increasing attention over the last years; however, its link to soil functions and soil management practices is still not well established. This study is the first to conceptually link the socioeconomic processes of external drivers for soil management with the natural processes of soil functions and connect them back to impacts on the social system. Application of the framework helps strengthen the science-policy interface and to systemically assess and compare the opportunities and threats of soil management practices from the perspective of goals set by society at different spatial and temporal scales. Insights gained in this way can be applied in stakeholder decisionmaking processes and used to inform the design of governance instruments aimed at sustainable soil management within a bioeconomy.
