Abstract

The aim of the present study was to extract information regarding the phosphorus content in a permanent grassland ecosystem, influenced anthropic by two different agricultural systems: exclusive mineral fertilisation and sheep manure farming management. The research was made in spring, in a hill region of Romanian Banat. Principal Components & Classification Analysis (PC&CA) was performed for statistical interpretation of data. The first two principal components described around 90% of the total variance. Forages total phosphorus content was positive correlated to the sheep manure farming system (0.84), and to the grassland soil phosphorus, total content (0.88) and mobile form (0.65).
