Permanent Grassland History Researches in Maramureş

Abstract

In the main part of the 20^th century, research on plant nutrition was focused on inorganic nutrients, its foundations being laid by the 19^th century chemist Justus von Liebing who identified the essential nutrients responsible with plant growth and promoted the use of mineral fertilizers. Although in the middle of the 20^th century plant nutrition was focused on mineral fertilizers, organic nutrients still have a long history of use in agriculture and research in this field established fundamental knowledge.

Permanent grasslands in Maramureş were the object of study and research from old times because of the vast area and the richness in herbal and wood species – as a result of the influence of the ecological conditions. The research conducted in the area can be divided in three periods - independent on the type of fertilizers used in the process - studies carried out during the 19^th century, studies held in the 20^th century and the ones in the 21^st century which are developed on the concepts of ecology and sustainability to support public policies and provide environmental benefits. Although the first two periods of research in Maramureş are rich in providing information on the flora in Rodna Mountains, ţibleş Mountains, Borşa etc. and on grassland development in the area, in the last century the research scale decreased making this space auspicious for developing new data in the field.
