One farmer used to have recurring problems with ear necrosis, mainly when the piglets were between 6 and 8 weeks of age. He and his veterinarian observed that he could reduce the amount of drugs after he started using lagoon. He dissolves lagoon in water and pours it through the slatted floor every three weeks – meaning twice within the eight weeks. Since he has been doing this, there have hardly been any necroses. The vet assumes that this is due to a reduced amount of ammonia in the barn.
Hay milk farms don’t feed silage but only hay and concentrated feed in winter. Therefore, there was a floating layer approx. 50 cm thick on the manure before using lagoon, as naturally a lot of undigested fibre material remains in the manure. Stirring up this manure in different places of the manure container took more than an hour. lagoon was applied according to usage instructions every fourteen days on a regular basis.
In April, the floating layer was down to approximately 15 cm. The manure could be stirred into a homogenous mass in a little under 10 minutes – and that from just one place in the container. The occuring smell was a lot more pleasant and mild than before using lagoon. The distribution of the manure onto the field was noticably more even, as fluidity was improved and the manure was more homogenous.
The farmer started to apply lagoon every 14 days, pouring it through the slatted floor directly into the slurry pit. He started beginning of January. Mid-February, the slurry pit was filled to the brim so that he had to pump off a small amount before being able to stir. The manure was liquid after just a short period of stirring and there was no clotting. Later on, when he prepared the manure for application onto the field, all of the manure could be set into motion by the stirring unit for the very first time - and even in significantly less time. Only the corners of the pit in which a larger amount of manure tended to settle were not totally cleaned out. However, there was no need to water the manure down in order to ensure a more even distribution.
Manure is precious! smell equals losses
Farm animal‘s excretement is full of nutrients, as in general the feed is only partially degraded. In most cases, undigested fibre components are directly excreted in the manure and may result in floating layers and a bad viscosity.
Odour formation cannot be entirely avoided. Each development of odour indicates a loss in nutrients, as it means that nutrients are evaporating, e. g. ammonia from urea.
Storage times for manure will be extended by legislation. Maintaining viscosity and pumpability is and will remain a huge challenge.
Manure is a precious asset – it pays to enhance it!
The bacteria contained in lagoon use the manure‘s nutrients to produce fibre-degrading enzymes. Thus, solids in the manure are reduced, time and effort required for stirring and pumping can be reduced and it is easier to distribute the manure onto the fields. Less stirring reduces costs and nutrient losses.
lagoon is a freeze-dried powder containing live microorganisms. It is added to the manure in small amounts. The manner in which the manure is stored (lagoon, concrete silo ...) is irrelevant. Ideally, dissolve the product in water and apply it during stirring – either directly through the slits or via the extraction shaft. lagoon works in all climates and stays active even under ice.
Bubbling after use of lagoon indicates an increased biological activity. The surface will stay wet for longer.
lagoon – not harmful to animals or environment
lagoon does not contain chemical or water-polluting ingredients. lagoon may be used to enrich the manure of all types of animals.
Effects on manure
The trials described in this leaflet were effected with manure from a cattle fattening farm. Dry matter was at 9.3 % at the beginning of the trial. After 3 months, it was down to 6.7 %.
Effect No. 1: Fluidity
The bacteria contained in lagoon feed on the nutrients available in manure and produce fibre-degrading enzymes, thus breaking down solids in the manure. Stirring up the manure before application in spring takes up a lot of time and energy. Both may be reduced with lagoon, as it reduces swimming and sinking layers and improves viscosity. It get’s easier to empty the container.
Effect No. 2: Odour reduction
The unpleasant odour of manure which may be noticed by you, your neighbours, or your animals, is significantly reduced. Ammonia defines the smell of manure. The bacteria contained in lagoon use ammonia as nutrient source and multiply. Farmers using lagoon have noticed a milder odour, especially on stirring or distributing the manure.
How does odour develop?
Odour develops when volatile fatty acids such as acetic or butyric acid, as well as aeriform ammonia, are released. The observation of a reduced smell in farm trials fits to the reduced content of ammonia-N.
Effect No. 3: Even consistency
As to the application of manure onto the fields, the trend is developing towards drag hoses or slurry injectors. This increases the danger of damaging the cultivated plants by applying a punctually larger amount of manure. lagoon improves the manure’s flowability. It distributes more evenly and is better absorbed into the soil. The fertilizing effects are spread more evenly. The manure is less aggressive and it’s easier for the plant to absorb the nutrients.
lagoon – in short
lagoon meets the demands made on the handling of manure and on manure additives in many ways:
- reduced smell ensures a higher acceptance (better image) and fewer losses (reduced emissions)
- reduces amount of flies ensures calmer animals, less stress and improved performance
- easier to stir and pump – saves power, hours of work and machine capacity
- improved flowability facilitates an even distribution and consistent fertilizing effects on the field
- easy to use in all storage facilites
- beneficial for animals, humans and the environment
lagoon – usage instructions
Dissolve lagoon in 10 - 20 times the amount of water.
In the barn:
Pour in between the slatted floor resp. into the pit while stirring unit is runnig. Use every 14 days.
Pour the lagoon solution into the hose and pump it into the container along with the manure.
