Those of us who are working on grassland problems fully realise that manuring is only one factor in production. Sir John Russell s&3 when he was in New Zealand that in considering the manurial scheme for any farm oneāhas first to decide what manure should be used, and then when it should be used. I disagree with this view. I first want to look at the farmer and then at his farm. In other words,a great deal of money can be wasted by inefficient management.
Work on the mineral content of pastures at the Cawthron Institute commenced in 1928, when a survey of the pastures of the Waimea County, Nelson, was undertaken.
The figures quoted below in regard to the use of fertilizers and lime refer to the 1929/30 season, unless otherwise stated.
In connection with the process of rotational grazing of pastures, the two following questions are of great practical importance.
A research worker in soil chemistry accustomed to conditions in England is soon conscious in New Zealand of many anomalies in the position that liming occupies in local farming practice.
The evolution of species in response to, and their perpetuation in harmony with the forces of the habitat is, I think, accepted by at least all ecologists.
In the following paper attention is drawn to the necessity of a better organisation of agriicultural research in New Zealand.
In practical agriculture it is essential when making investigations and experiments to keep in mind the need of the farmer: i.e. - that the investigations and experiments be conducted in such a way that truly sound and reliable results may be secured. If the information given to the farmer is misleading, i.e., the experiment or investigation fails to obtain the truth, then the farmer who heeds erroneous instructions must lose accordingly.
