How to publish in this journal


LANDTECHNIK is a scientific open access journal that publishes studies and results from applied research in agricultural engineering. Topics range from the development of methods and research equipment through to the use of technology in crop production, animal husbandry and energy production right up to environmental engineering and information technology. We support scientists and young professionals from research institutes, industry and agricultural engineering companies in the publication of their projects in order to further develop an interdisciplinary exchange of knowledge in agricultural engineering.

The SJR is a size-independent prestige indicator that ranks journals by their 'average prestige per article'. It is based on the idea that 'all citations are not created equal'. SJR is a measure of scientific influence of journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from It measures the scientific influence of the average article in a journal, it expresses how central to the global scientific discussion an average article of the journal is.

Citations per document

This indicator counts the number of citations received by documents from a journal and divides them by the total number of documents published in that journal. The chart shows the evolution of the average number of times documents published in a journal in the past two, three and four years have been cited in the current year. The two years line is equivalent to journal impact factor ™ (Thomson Reuters) metric.
