“…So, a good evaluation of no tillage needs a full GHG accounting approach (Six et al 2004;Batlle-Bayer et al 2010)Extra carbon sequestration ranging from 97 to 1,000 kg C per hectare per year have been reported (Six et al 2004;Chatskikh et al 2008;Batlle-Bayer et al 2010). The effect of no tillage on nitrous oxide depends on the region and the related climatic conditions.…”

“…To simulate the difference in carbon sequestration between conventional and no tillage, the decomposition rate of no tillage is calibrated on the basis of Danish data (Chatskikh et al 2008). The rate is 1.5 times higher compared to grassland, whereas the decomposition rate of conventional tillage is 3 times higher.…”

“…The magnitude of the losses of soil organic C and N depends on the region, the previous land use and the used crop (Fargione et al 2008;Pineiro et al 2009). The use of no-tillage systems is also known to have significant effects on the levels and sequestration rates of soil organic C and N (Grant et al 2004;Six et al 2004;Chatskikh et al 2008). The use of no tillage systems is increasing in North and South America and in Europe as well.…”

Increasing the digestibility of cattle rations by feeding grains and whole plant silages from maize have been identified as effective options to mitigate greenhouse gas emissions. The effect of ploughing grassland for maize crops have not been taken into account yet. A intensive dairy farm is used as an example to demonstrate the trade offs by this type of land use change when more maize silage is fed to dairy cows. The model DAIRY WISE has been used to calculate the mitigation by the changed ration, the Introductory Carbon Balance Model to calculate the changes in soil organic carbon and nitrogen caused by ploughing grassland for maize crops. The losses of soil carbon and the loss of sequestration potential are much larger than the annual mitigation by feeding more maize. The ecosystem carbon payback time defines the years of mitigation that are needed before the emissions due to land use change are compensated. For ploughing grassland on sandy soils, the carbon payback time is 60 years. A higher global warming potential for methane can reduce the carbon payback time with 30%. Ploughing clay soils with a higher equilibrium level of soil organic matter increases the payback time by maximally 70%. The payback times occur only in the case of permanent maize cropping, grass maize rotations cause annual losses of nitrous oxide that are larger than the mitigation by feeding more maize.

“…According to Fødevareministeriet (2008) and Chatskikh et al (2008), reduced tillage (and direct drilling), which are methods that reduce labour and energy efforts, show a great CO 2 e reduction potential. The reductions can mainly be attributed to reduced energy uses, increased storage of CO 2 in the soil and net changes in the emission of nitrous oxide.…”

Title: Should farmers participate in the EU ETS? Permit price, measurement and technology. Journal of Environmental ManagementWe have now revised the paper according to the proposals of the referees. We have considered all the points made by the referees. Below we provide an overview over our response to all the referees' comments. (Marked with yellow). We also shortened the paper according to the advice of the editor. If the paper is still too long, we would be willing to remove the appendix.We want to thank the two referees for valuable comments and suggestings that have improved the paper significantly.Reviewer 1's comments 1. The structure of the abstract is not sound enough. The author/authors should write a comprehensive abstract based on the result and discussion.We have changed the abstract according to the guidelines of the referee 2. Introduction: There are some non-pertinent statements in the Introduction. It should be reduced as the scope of the paper. There are so many facts used in the Introduction without providing the evidences. Please improve it.We have significantly changed the introduction and made it even more focused. The title has also changed according to the revised main question, i.e. how to develop a project-based system for including farmers in the EU ETS. We have eliminated several paragraphs, including the part that farmers are affected by climate change, and the part of the future plan for the EU TPS market, to strengthen focus in the introduction.3. Methods: The way of realizing the objectives of the study is not clear. Please improve it.In the end of the introduction, we have added a large paragraph on the method we employ, namely economic theory. It is now considered how we apply this theory on the research question at hand.4. Results, and Discussion: Please restructure your results with relevant discussions which will let the readers clearly understand your findings.We have included a large paragraph in the end of the introduction that describes our methodology, and the main analysis and findings.5. The conclusion should be more precise.We have changed the conclusion such that it focuses more on the results and implications of our analysis in relation to a project-based system for including farmers in the EU ETS *Detailed Response to ReviewersReviewer #2:(1) Anstract need to be rewrittenHas been done, according to the guidelines of the two referees (2) In page 2, Last para: Authors argue that there is a research gap in the given topic, in fact it is not solely true. The problem here is that Authors mostly cited reports and websites, they have not gone through journal articles. I ask them to go through journal articles. For example, see Maraseni, T.N., We have added the following paragraph: The idea of including farmers in a national emission trading system has been launched in Australia (Maraseni 2009; ABARE 2010) but it has not yet been applied to the EU. This is our contribution to the literature.(3) in page 2, last para: I ask authors to discuss latest debates of United State...

“…To date, there has been no consensus on soil CO 2 exchange patterns as affected by soil management practices. Numerous studies have revealed relatively higher SR and CO 2 fluxes under conventional tillage (CT) compared to reduced tillage (RT) and NT (La Scala et al, 2006;Chatskikh et al, 2007Chatskikh et al, , 2008Luo et al, 2010;. Elder and Lal (2008) documented insignificant differences between CO 2 fluxes in CT and NT.…”

°C is 2718 °C and the growing period lasts only 195 days. However, during the last decades, air temperature exceeding 25 °C has been registered 12 and 25 times per year at the Baltic Sea coast and in the continental part, respectively (Bukantis et al., 2000;Bukantis and Valiuškevičienė, 2005). According to the HELCOM assessment, hot days will become more frequent and severe Abstract: Climatic conditions of environmental zone Nemoral 2 of Europe are favorable for agricultural development. However, more frequent events of hot air-waves and prolonged droughts occurring as a consequence of climate change lead to soil moisture content reduction down to the plant wilting point. Dry soil conditions may have negative consequences for soil as a habitat. The goal of this study was to evaluate the cumulative after-effect of long-term conventional (CT) and no-tillage (NT) application in combination with or without crop residues on soil physicochemical properties, microbiological activity, and soil respiration (SR) under prolonged dry soil conditions. Long-term CT with residue returning created a soil environment that was more resistant to dry conditions than NT. Longterm CT with residue returning created a qualitative soil environment in which the main direct determinants for SR were fungal (F) and bacterial (B) community and carbon/nitrogen ratio (C/N). Slightly weaker contributors for SR were available phosphorus (PAL), plant wilting point (PWP), plant available water (PAW), and urease activity (UR); however, they acted as indirect factors. Long-term spreading of residues on soil surface under NT determined the decrease in water capacity in mesopores and micropores. Significant reduction in field capacity and PWP was revealed, while PAW remained unchanged compared to NT with residues removed. Main direct determinants for SR were F and PAL. Slightly weaker indirect contributors for SR were B, dehydrogenase, UR, and PAW.
