| Popis: | Diversity is a term no longer alien to any social category (the ordinary peasant political class) and became the main topic in any actual problem. Phytodiversity are in decline and all policies try to focus their attention to this problem. The importance of grassland ecosystems is increasingly exploited demonstrated and changes lately whether political, economic and / or social affects not only the ecosystem but the whole agricultural system in the world especially fertilization. This is the reason why our experience include a study on semi-natural grassland based on combined form of organic and mineral fertilization. The experiment was placed after experimental technique method and includes six different fertilized treatments in four replications. Experiment is establish in Baisoara Commune, Cluj County. The experience includes four variants in three repetitions, which are: V1 – control variant, (unfertilized); V2 – variant fertilizer with 10 t/ha manure; V3 – variant fertilizer with 10 t/ha manure + 50N25P25K; V4 – variant fertilizer 20 t/ha manure; V5-variant fertilizer with 10 t/ha manure + 100N50P50K and V6-variant fertilized with 100N50P50K. Like is known, mineral fertilization reduce more than organic fertilization the phytodiversity and in our experiment this are very good highlighted. The studied phytocenosis present a Shannon diversity even if large mineral inputs are are provided. |
