PASTURE CULTIVATION
STIMULUS TO GRASS GROWTH In a country such as New Zealand, where the originally liberal supplies of humus in the soil have been heavily drawn upon for exportable production, and where artificial manures are almost solely relied upon to maintain or increase the soil’s fertility, the maintenance of humus in the soil is of vital importance. . Sun-dried and lifeless animal manure, left scattered over the surface of the soil, is of little value when, if ever, it becomes incorporated with the grassland by the process of trampling with stock. Severe harrowing not only breaks up and distributes this manure evenly, but effectively introduces a large proportion of the matter into the surface soil, where it becomes available to the bacteria. This and the aeration which such harrowing promotes, largely accounts for the stimulus to grass growth which is always a noticeable result of the severe harrowing of old pasture.
