Table 6 Chemical analysis for each species by location. Plants harvested and analysed for nitrogen (N), protein, phosphorus (P), Potassium (K), acid digest fibre (ADF) and total tannins (TT). N, protein, P and K are given in % dry matter, ADF as % and TT as % equivalent to tannic acid. Means followed by different letters are significantly different at the 95% confidence level, SE in parenthesis. Superscript refers to Estimated Marginal Means post-hoc analysis within sites with different letters significantly different at P < 0.05; ('a' refers to largest value, 'b' is smaller etc.)
