Kookaburras love our soil improvement, more worms for everyone!

There must be something going on out in the field by the look of these kookaburras, perched on our brand-new, second-hand tractor. 
Can you see six of them?

We are always working on our soil to improve our ability to grow tasty and nutritious food.
This Autumn we sampled the soil in all of our fields and sent them off to the lab for analysis.
The results show continued improvement over the period of time we have been farming here. However, they also show that we have room for further improvement.
The main problem we have is the low level of organic matter in our soil.
Organic matter, which is derived from the result for total carbon, comes is at 2.5% to 3.5%.This is sharply higher than the less than 1% that we got from the soil tests 15 years ago.
But it is still much less than ideal because low organic matter in sandy soils causes a low exchange capacity which measures how much nutrient the soil can hold. Because of the low EC, our soils are chronically low in calcium and magnesium plus some of the metallic trace elements such as Boron.
The soil treatment we have chosen for the cool season is to add compost plus dolomite (calcium magnesium carbonate), boron and potassium sulphate.
Now, we are busy working this mixture into our soils. To help this, we have invested in a second-hand Korean tractor plus a Croatian rotary hoe from our friends Mark and Jenny at
Glasshouse Tractors.
The rotary hoe is slightly wider and more heavy duty than what we have been using. We expect cultivation with the new hoe to produce a better survival rate for seeds and seedlings and fewer weeds in the bed.
The results will be available for all to taste in a month or so.
