Earlier this year we purchased a truckload of premium organic compost from Jindalee Ag to be used as a trial in our truffière with the purpose of improving the soil structure without introducing animal manure or organic matter that will influence the truffle development.
We are still in the very early stages of this trial. It will probably take at least 2 years before we can determine its full effect. Of course, we will be able to see earlier what it will do to the soil structure and also the possible reduction in irrigation frequency. What we can say at this stage is that the product was nice and clean, no contamination was observed. We had a bit leftover which we used on our grazing paddocks and we saw a noticeable improvement in the growth and the colour of the pasture. This was in February/March so still a very dry time of the year. We were so impressed with this that we ordered another load in April to use on all our grazing paddocks.
