Convert Rate per acre into Rate per 120 litre (or 200 litre)
This article explains how to convert ‘Rate per acre’ into ‘Rate per Litre’.
Boom Spraying (Farmland and large grass area fertilising)
When spraying with a boom, several factors need to be taken into account (pump flow rate, nozzles driving speed, foliage density, etc..)
But the different volume of water you use doesn’t matter, as long as the correct amount of the actual fertiliser concentrate is added to the tank.
Example
person (A) adds 2 litres of New Zealand Organic Seaweed Fertiliser to 120ltr of water and boom sprays the mix onto one acre, person (B) adds 2 litres of New Zealand organic seaweed fertiliser to 200 litres of water and boom sprays onto 1 acre.
In both cases, the acre receives the correct 2 Litres of fertiliser, The different water amount doesn't matter
Experenced sprayers of fertiliser already know what volume of water to use for their land as each padock has a diffrent landscape eg. hills, trees and muddy tracks etc..
I base my calculations on 2 litres of seaweed fertiliser concentrate to 1 acre or .41 hectres and have found this works great for a twice a year application once in the spring and once in the autumn season on a flat 1 acre farm grass paddock.
Hand spraygun & Knapsack (garden and spot tree fertilising)
people who are doing area-type spraying with a hand spraygun or a knapsack don’t generally know how much water is needed for them to spray in a given area. That's because those types of equipment are generally used for spot spraying, not area spraying.
Try a 5 litre (5000ml + 125ml concertrate) mix of 1:40 seaweed fertiliser in a knapsack unit.
so you can test it on a small area or a few trees on your farm or orchard etc.. to see how much you will require for your needs, you will see results with'n 2-3 weeks of spraying New Zealand Organic Seaweed Fertiliser.
Waterpump spray unit (Farmland and tree fertilising)
This is a NZOSF method of spraying fertiliser onto large tress and small farmland. It's very
efficient , covers moderate areas and can spot target hard to get to places that conventional boom spraying cannot get to, making this nzosf's preferred system for spraying New Zealand Organic Seaweed Fertiliser
If you want to remember how to convert acres to m2 and acres to hectares etc... use this simple estimation rule
and you will be very close to the proper figure you require, its easy to remember.
It goes like this:-
remember the number 1 and the number 4 with this 1 acre = .40 hectres , 1 acre = 44000 square feet , 1 acre = 4000 m2
"so 1 acre to .40 hectres or 1 hectre to 2.5 acres ( .40 +.40 +.20 = 1.00 ) , 1 acre = 4000 m2 etc......":
Remember the number 1 and 4 always calculate to "one acre" its easier to remember and you can quickly extimate how much New Zealand organic Seaweed fertiliser you will require for your needs.
