How Much Liquid Manure Should I Use on My Farm?

by Maureen
(New Zealand)

I am wanting to make liquid fertilizer from our chicken and Alapaca manures. We have 10 acres of x dairy land and run Dexter Cattle, Alpacas Sheep and Chickens. We get Balage made yearly (Balage is grass that is baled and wrapped soon after cutting, minimising the risk of loss through rain). This year we want to get hay as well off one of the paddocks (should give 60 bales approx). How much liquid "manure-tea" fertiliser should we put on each acre, how strong and how often?

I want to make the land more healthy so that it will help keep our animals healthy, with the topical applications of fertiliser.

Poultry Manure Tea
by: Daniel Reuben

I think one must not use "Poultry Manure Tea", (this goes for Horse, donkey, sheep, camel manure teas too) it is too strong in especially Ammonia and not N2 (these differ from layers to meat birds to free ranging birds) and that's why strong odor.
Poultry manure should be composted first with 30 cm layer of green and brown material to 10 cm layer of fresh poultry manure (Horse manure is tricky thing requires more attention than explained here). Follow composting technique.

1 kilo this compost to 5 liters of water, a table spoon full of molasses (or 1 to 2 teaspoons of demurrer sugar) ferment it for about 8 to 15 days, aerating it by bubbler or stir it 3 times a day. Take 10 liters of this compost tea to 100 liters of water for irrigation application (through soil) or 3 liters of compost tea to 100 liters of water for spray. (Spray will solve lot of other problems like diseases and fungal attacks.)

Application should be 3 weeks apart from one application to the next. Application through soil and spray should be at list 3 days apart from one another.

Poultry manure is hot!
by: Jacki

If you use poultry manure, a lot depends on if it has litter with it, and also how long you ferment it. I've used it a little, and believe me, it stinks! There were times when I didn't want to lift the lid off the plastic garbage container it was in. Eventually, after several weeks, it seemed to lose the stench, and then just smelled earthy.

When you're applying it, I would do as Meg suggests, and keep track of where you put it. You may be fine if you already have lots of organic matter, which means you have micro-organisms, already in the soil. If you don't, start with a more dilute application, as the salts in it will kill off everything.

Also, if you haven't had a soil test, at least test the pH. This can make a huge difference, especially on grass pasture. Last year, all I did was add dolomite lime onto my grass, and there was a huge improvement.
Let us know how it goes.

Try this...Cautiously!
by: Meg

I have no experience with broadacre application of high N liquid fertilizers. However, from my calculations a rate of 10,000 L of tea (made from 1 part poultry manure to 20 parts water) per acre sounds about right, applied onto damp soil. It would be safer to start with twice as diluted on a test patch first and gauge the results.
