Plot sizes and farm-plot distances affect the economic performance of agricultural production. Their effects likely differ between conventional organic farming systems due to major differences in crop production programs. Our paper quantifies these based on big data resource requirements field operations, summarized by regression models. Combined with detailed case study information obtained through interviews, we assess plot size distance for three farms which recently converted farming....
Deciding on which crop to plant a field and how fertilize it has become increasingly complex as volatile markets, location factors well policy restrictions need be considered simultaneously. To assist farmers in this process, we develop the web-based, open source decision support system 'Fruchtfolge' (German for 'crop rotation'). It provides makers with coarse manure fertilization management recommendation each based solution of single farm optimization model. The model accounts specific...
With the increasing availability of sexed semen, farms have opportunity to select genetically superior dams produce their replacement animals and crossbred calves for beef production higher economic value than remainder herd. However, costs reduced fertility semen complicate decision when what extent should be applied in a The objective this study was explore economically optimal utilization crossbreeding among North Rhine-Westphalian dairy holistic single-farm model. For analysis, we...
Abstract This paper investigates the Maximum Acquisition Values (MAVs) of weeding robots and their determinants in both organic conventional sugar beet farming Germany. The MAV is defined this as price robot that renders same net profit current methods. For our analysis, a Monte Carlo simulation approach used, combined with empirical data collected from companies. results show MAVs mechanical for are substantially higher than spot spraying farming. Technology attributes more influential...
Abstract Legumes, which currently show low production levels in the European Union, can reduce negative environmental externalities of agricultural systems by lowering nitrogen (N) fertilization and increasing protein self-sufficiency. This has led to introduction coupled support France, contrast Germany. However, German implementation Nitrates Directive is more favorable for legumes. Our study assesses economic impacts these two policies affecting legume production. We employ bio-economic...
Farm-scale and agent-based models draw typically on detailed preferably spatially explicit single farm data. Data protection standards however restrict or exclude their access, as for example in Germany. We provide data a synthetic population of the German federal state North Rhine-Westphalia, mainly based Farm Structure Survey 2016 plot specific crop from 2019/2020. The is derived typology at administrative unit level to which observed plots are allocated afterwards. contains 25,858 farms...
This paper presents analyses of the economic and environmental impact relevant phosphorus management policy scenarios, using representative pig poultry farms in Emilia-Romagna region (Po River basin, Italy) Niedersachsen (Ems Germany) as case studies. The analysis was done by a farm-level linear programming bioeconomic model developed for different farm animal types—sows, fattening pigs, laying hens broilers. baseline assessed scenarios involved situated within Nitrate Vulnerable Zones...
Despite their application in research and political consultancy, crop planning models have been rarely adopted agricultural practice. High data requirements are claimed to be one of the main reasons for implementation gap. The objective this contribution therefore was create a model that focuses on both farm adaptation as well usability. In order achieve goal, an interactive web-application built. Through use linked open data, allows personalised optimised cropping plan within less than 10 minutes.
