The objective of this study is to reveal the qualitative changes caused by organic fertilization in Agrostis capillaris L. and Festuca rubra L. grasslands in the upper basin of the Suceava River. The study will be used, as a starting point, to identify the necessary measures for the sustainable management of these grasslands. The study was conducted during several field trips between 2009 and 2011, in Poiana Cerbul, Putna village, where we set up a fertilization experiment comprising five variants and three repetitions. Based on ADF and NDF content of feed, quality values were calculated: RFV, NEL and TDN. Using organic fertilization we have achieved an increase of the forage quality, with significant differences, distinct significant or very significant compared to the control variant.
