Do you know what your farm is worth or are you guided by what someone is willing to pay for it?
When I ask this question invariably nearly everyone misses the point.
We never actually evaluate the nutrient $ value in the soil! And this is really important stuff.
If you’re in agriculture for the long term, you don’t want to have to pay for the farm more than once.
Farmers take soil samples, but they are only based on what is plant available at any given time.
But this gives no idea of what we are actually dealing with and what is actually part of your soil asset.
A Total Soil Test is in reality is akin to a mining assay. The soil is completely broken down and the total amount of nutrient is measured.
We do these tests based on 150mm (6inch) profiles and can then calculate out how much nutrient is in your soil and then calculate its real value in dollar terms in today’s value.
At present prices of Super Phosphate 0 – 9 – 0 – 11 at around $300 a ton x 9% = $3.45 kg of Phosphorus.
To give an example of what we are not utilising I’ll quote from a soil sample taken in Central Otago a couple of years ago.
Total Test for Phosphorus came to 2838kg of P per hectare x $3.45 = $9,791.10 worth of superphosphate in the top 150 mm per hectare.
Now this is just an example. If I went through the rest of the test, the total soil nutrient value comes to about $40,000 a Hectare and that’s just calculating Phosphorus, Calcium, Magnesium and Potassium.
Comparing the total test to the available Nutrient Test we can calculate that in that soil’s present state we have $8,460 per Ha available for use.
Wow, we are only looking at utilising 20% of our investment.
To crack into the stockpile of plant nutrients on your farm all it takes is education and a change in mindset and some key ingredients.
Firstly do something about it!
