Compost fertiliser programs
We can demonstrate that the nutrients in a compost program can equal or better a conventional fertiliser program in both cost and nutrient supplied.
We’ve always known that incorporating compost into a fertiliser program was a cost effective way to deliver the right nutrients for your soil’s requirements and now we can demonstrate this with our compost calculator.
The budgeting tool lets us:
- stay within or below the budget set by you
- choose amendments that improve the fertility of your soil
- demonstrate how tailored compost compares to conventional programs
- manage any deficiencies
- lift biological activity
- add carbon
For example, 2.5 tonne of compost at $100 applied per hectare is the same amount of N, P, K as applying 130kg of single super, 50kg of Muriate of Potash and 80 kg of urea at $124. Plus there is more than 500kg of carbon and more calcium.
One tonne of compost has more than $55 worth of N, P, K, S, Calcium and carbon. In addition, there are the many trace minerals biological species, enzymes, vitamins and carbohydrates.
Let’s see how it compares with a conventional fertiliser quote:
All of these nutrients are very plant available, stable and not leachable.
Tying up the nutrients with the organic matter or carbon means the nutrients are still able to be digested by the biology and released as plant-available food.
Most water soluble fertilisers are readily used by a plant when applied, but if not used within a short period of time will either leach or run off (water soluble), or tie up with another element. This tie-up is undesirable as plants and bugs find it difficult to break the bond.
Ultimately, we want the nutrients to tie up with organic matter to stay in a form that the biology can easily access, which is why ideally, traditional fertiliser is spread with compost.
