In grazing systems, the quality of the pasture is an ever-changing scenario: weather, forage variety, level of fertilisation and age of the plant are some of many factors influencing the quality of the cows' diet.

This results in a predicted loss of volume growth at high levels of fertilisation application and site index.

This concentration typically results in moderate to high levels of fertilisation success [26].

Soil and biomass CNP increased with increasing P fertiliser, and there was a significant, positive, correlation between microbial biomass P and biomass C, apart from at the highest level of P fertilisation when the microbial biomass was over-saturated with P. The molar ratios of C N P in the microbial biomass remained constant (homeostatic) despite large changes in the soil nutrient ratios.

The probabilities of identity by sexual reproduction were calculated using the software package GENCLONE 2.0 [48], which implements a method that takes into account the FIS estimated from each population [49] as S. hystrix is known to show some level of self-fertilisation [32] and deviations from HWE were observed in some of the sampled populations.
