| Objective of this paper is to compare different measurement concepts for sustainability at farm level in Germany: a) Sustainable Value Approach (SV), b) Data Envelopment Analysis (DEA) and c) indicator approaches close to KUL (Criteria for an Ecologically Compatible Land Management). The mathematical programming model FARMIS is extended wrt the underlying subject and applied for quantitative analysis. Indicators based on physical inputs are calculated based on monetary data of national FADN data. The methods are applied to a sample of about 4000 representative dairy farms. Results of SV are given in both absolute values and return-to-cost ratios which take farm size into account. Considering relationships between methods we found out that correlation... |

| Anthropic action, such as the soil use and management systems, promote changes in the soil structure. These changes might hamper the development of plants in soil management practices that involve its mobilization, and the negative effects might be increased due to intensive use. The aim of this study was to evaluate the physico-hydrical properties of a Haplohumox in integrated production systems under different soil managements. The soil superficial (0.0-0.10 m) and sub-superficial (0.10-0.20 m) layers were evaluated in the different systems: conventional tillage (CT), minimum tillage (MT), no-tillage (NT) and chiseled no-tillage (CNT), taking into consideration the annual ryegrass cropped for different uses [cover crop (C), grazing (G) and silage (S)]... |
