Landcare's philosophy is about stewardship and fostering our land and resources. In relation to the management of a farm enterprise, managers need to treasure and protect the environment they work in and also that of their neighbours and the greater ecosystem. A manager has to be aware of how waste is managed, how pests and disease are dealt with, how the soil is nourished and not depleted and as a result must make important purchasing decisions (eg. organic fertiliser, not overstocking, crops that suit the land) set up appropriate processes and lead their team of workers in a way that will either maintain or better the land.
The physical aspects of the farm need to be taken into account, in that soil should be monitored and improved (composting, pH testing, appropriate till strategies, crop rotation, green manure). Avoiding soil compaction, erosion or degradation through poor management is a priority and keeping an eye on what is succeeding and what isn't, for instance monitoring crops and choosing a better strain that is better suited. Caring for the farm requires constant effort and observation. Diversity is also important. Ideally following some organic and permaculture principles would line up nicely with the objectives of landcare.
