- P.S.: Flying sprayer
- Air pressure sprayers
Pressure: Specially for Horn Manure exist recommendations for low pressure (0.8 bar, 2 bar). It seems that at higher pressure parts of the effect get lost.
Materials: See remarks for stirring vessels.
Everything in a beer crate: Compact and easy to move.
- On top: Drawing in tube with filter: For the preparation, I can use any container.
- Diaphragm pump (left on top).
- Accumulator 12 volt (left below).
- Expansion tank (red).
- For Horn Manure: Windscreen wiper motor and a plain orifice nozzle. (right side)
You can see the jet of the Horn Manure going up to the right side.
The preparation is in a vessel on the three point hitch.

Animals can also go where and when tractors etc. cannot drive. They do lesst harm the soil.
My prefered sprayer for Horn Silica. The ventilator brings a mist on everything. You can work big areas and high treetops.
You can vary the quantity of the preparation without limits.
Disatvantage: Two-stroke engine: It makes a loud noise and works with a mix of oil in the gasoline.
My preferred way to spray Horn Manure.
It pumps and sprays whilst stretching and contracting.
You can hold it in different position. That makes it less strenuous.
It is sold as a bucket sprayer. I put a container in a knapsack.
They do not cost too much. Good for small surfaces.
Pumping air in by hand needs some time and can be strenuous. When you can fill them with compressed air, you can work faster and easier.
Market gardeners like them.
You can put small ones into a knapsack sprayer. I worked so when I walked on crutches. That is also a way for children to spray.

Drenching roots with Horn Manure Preparation
Around the periphery of the treetop, the two women lift the soil with the help of digging forks to make cavities.
The man fills in Horn Manure.
Spraying treetops with Horn Silica etc.
I have put a long tube on the sprayer and fixed it on a telescopic bar. It is not the easiest way, but if you have only some single trees, it is an option which does not cost a fortune.
For small surfaces.
You also can work with a cup.
Or with the bare hand.
The pictures are taken from my book: „Die Düngerpräparate Rudolf Steiners…“ You will find there detailed descriptions of these and other sprayers.
The big book of the Bio-Dynamic Preparations.
I know some self-constructions of air pressure sprayer. But they can be a risk. If you pump too much air in, they can explode.
