Pasture and weeds

As part of the project to compare the performance of the conventional and organic dairy farmlets, the composition of the pastures within each farmlet was monitored over the duration of the trial. This mainly involved taking detailed measurements along set transects within 10 paddocks in each farmlet. The grass – clover - weed balance was determined every 6 months, and also the proportion of each weed species was recorded from within fixed quadrates at each time of assessment.  

This allowed changes in pasture and weed composition to be followed throughout the experiment, which changed quite dramatically whenever a pasture was replaced but otherwise remained fairly constant.  Measurements were also made of the mineral content of pasture components at times.
