In these trials Corrigin Farm Improvement Group aimed to test the benefits of growing crops on chemical fallowed soil. The trials specifically compared which crop species were most profitable under a chemical fallowing regime. In season 2013 barley was most profitable and in 2014 albus lupins were the most profitable crop grown on chemical fallow.
This project was designed to test the relative benefit of chemical fallow with a range of different crop types. The trials compared different crop types on chemical fallow with the aim to identify which crop is likely to produce the highest return. The trials was a joint effort with Pulse Australia with the aim also to demonstrate and test pulse species in the Corrigin district.
2018
Soil moisture measurements were taken on the 24th of May 2013 to confirm whether there had been carryover moisture from season 2012 in the bare areas of the paddock (due to mice damage in 2012). Based on the soil moisture tests below, and with regard to the bared areas observed in the paddock, the area shaded blue was identified as the only area with a potential representation of the chemical fallow effect. So in regards to final crop yield, this is the only one that was used for continuous crop versus chemical fallow comparisons.
2019
It was observed on the 23rd of July for both the wheat and barley, continuous cropped plots, were less vigorous and weedier than the respective chemical fallowed plots. For the canola on this day the chemical fallowed plot has commenced flowering sooner than the continuous cropped canola plot. There was more purpling on the continuous cropped canola compared with the chemical fallow plots which was possibly a combination of nitrogen deficiency and herbicide damage from the chemical, Intervix. On the 23rd of July it was also observed no differences in vigour between continuous cropped chickpeas and albus lupins when compared with the respective chemical fallowed plots.
On the 31st of July it was observed that net blotch disease had infected the barley plots and needed spraying with fungicide.
On the 1st of December when the trial was harvested it was observed that the chemical fallowed albus lupins appeared to have more terminal pods when compared with the continuous cropped plot. On this day both canola plots showed symptoms of severe shedding. The continuous cropped canola plot was thinner and shorter compared the chemical fallow canola plot. For both the wheat and barley, the chemical fallowed plots were thicker than the respective continuous cropped plots.
The trials over the two seasons has been a valuable learning experience for members of the Corrigin Farm Improvement Group (CFIG). There has been four group field days at the sites and three other smaller group visits including members of the GRDC Western Panel in 2013. The trials have also been an opportunity for CFIG and Pulse Australia (Alan Meldrum) to work together showing farmers pulse options in our area. The results of the trials were presented at the CFIG AGM in early 2014 and will be presented in March 2015 at the CFIG Crop Updates.
Soil moisture measurements were taken on the 24th May 2013 to confirm whether there had been carry over moisture from season 2012 in the bare areas of the paddock (due to mice damage in 2012). Based on the soil moisture tests below, and with regard to the bared areas observed in the paddock, the area shaded blue was identified as the only area with potential representation of the chemical fallow effect. So in regards to final crop yield this is the only that was used for continuous crop versus chemical fallow comparisons.
The trial results show that chemical fallow can offer some large yield and margin gains and these are not limited to cereal crops. Break crops like canola and pulses may offer another seasonal break from cereals to subsequently improve the success of following cereal crops. These higher value break crops, in their own right, may be more profitable than a cereal crop on chemical fallow as indicated by the results in 2014.
Chemical fallow will continue to be adopted in medium rainfall regions if it can help reduce volatility in crop returns by improving crop yields and reducing average inputs costs over a number of seasons. These trials were conducted over two, above average seasons, yet the benefits of chemical fallow were still realised with some of the crop types. It is generally well accepted that chemical fallow can offer higher relative gain in dry seasons. So it is the combination of production upside in both poor and good seasons which means chemical fallow can help reduce the volatility in crop income.
