Description of study
What?
A comparative study of the quantitative depressions in wheat yield and quality that result from sheet erosion was conducted at five Soil Conservation Research Stations over fourteen years (1955 – 1968). Data analysed for each Research Station was obtained over different time periods.
When and Where?
The study was conducted at the Inverell Research Station from 1956 – 1965.
How?
Two blocks were implemented on the site, one comprised of a wheat-fallow-wheat rotation and the other comprised of a fallow-wheat-fallow rotation. Three replicates of each treatment were randomized on each of the blocks. The treatments were as follows:
- Control – no soil removed
- Three inches of surface soil removed
- Six inches of surface soil removed
Each plot had a furrow dug along the entire length of the lower side to provide drainage and prevent run-off washing from plot to plot. Each plot had a harvested area of one hundredth of an acre or six rows of a combine for the required length.
Normal cultural practices were carried out throughout the experiment. Manual harvesting was completed and the seed was then threshed, cleaned and weighed. Samples were also tested for nitrogen determinations using the Kjeldahl method.
