I though I would try and put some simple numbers around what a 21 % increase would mean to a Buk Choy grower in $ terms per ha.
Assumptions:
1. 15 tonnes per ha.
2. $2.15 Au per kgdivide by 4 for farm gate price $0.54c kg
3. OHD weekly at 5 l ha.
4. OHD $2 per litre.
5. 30 days from planting to harvest
6. 4 foliar applications OHD
7. grown outdoors
So 15000 kg + 21 % = 18150 kg - 15000kg = 3150 kg x .054c = $1701. per ha extra
Costs involved
4 sprays @ 5l/ha = 20 l/ha @ $2 per l= $40 per ha
Labour tractor + operator $150 per hr [ contractor price/ much cheaper using own equipment] spraying with boom sprayer @ 8 km hr 6m boom spray width will do 1 ha in 15 min. I know this because I fungicide spray grape vines with a double row sprayer.
15 min x 4 sprays = 1hr
So lets put that together.
$150 for labour/equipment
$40 for the BioS
$190 total cost for a benefit of $1701......so
$1511 extra to the bottom line per ha.
I think its important to see how little actual impost there is. I believe my figures are on the high side as labour/equipment price is for contractor you could easily halve that cost using your own gear, a wider boom sprayer, spraying it out with other sprays being used.
I doubt there will be a Buk Choy farmer on the planet that would not spend $190 to get a $1500 increase in return. AIMO DB.
ps: please feel free to pick my numbers apart I'm not infallible.

the question is, how does this cost compare to other biostimulants?
If OHD "mimics" other biostimulants and is sold at 1/2 the price of other biostimulants, then the total cost of spraying OHD is only $40/ha less than other biostimulants - not much of a saving!!!!!!
