Add 20 g of Active NS per m3 of slurry in the reception pit and agitate vigorously before pumping into the storage tank. If Active NS is used all the time, regularly add 20g of Active NS per m3 of slurry added since the previous treatment. Agitate before pumping the slurry into the storage tank.
Use 20 g of Active NS per m3 of slurry in the storage tank. Add Active NS before or at the same time as agitating the storage tank. If there is a floating crust on the storage tank, puncture it with the agitator. Pour the Active NS directly down by the agitator to make sure the Active NS mixes thoroughly with the slurry right away. This produces the best effect.
Lagoons can be a challenge as it is usually pumped around the lagoon. Add Active NS with 20 g per. m3 slurry in the lagoon. Thereafter, the pump is pumped vigorously so that the precipitate is processed and Active NS is mixed.
Since the precipitate is often very solid, it is supposed to drain the lagoon 3 times before it is completely empty. Active NS must be applied to all new slurries that have not been treated to get the maximum effect.
For how long does Active NS remain effective?
After being added to the reception pit and the slurry tank, Active NS stays active for more than a year, but more Active NS should be added whenever new, untreated slurry is introduced. Use 20 g per m3 of slurry added. You should always thorough agitation the tank before starting to offload the slurry.
Get off to a good start with Active NS
If you start using Active NS mid-season, you must first empty the slurry out of all channels and containers. Then add 20 g of Active NS per m3 of slurry in the slurry tank.
Now Active NS can be used in the channels and containers; add 20 g per m3 of slurry expected to be found in the channels and containers by the next emptying. Active NS now works until the next emptying.
If Active NS is always used in the channels and containers, there is no need to add any extra product to the slurry tank.
Under normal circumstances, a floating crust will form more readily after using Active NS. The floating crust will gradually build up over the summer.
What could prevent the formation of a floating crust?
A lot of heavy rainfall during the summer could break up the thin floating crust, so the floating crust would have to build up again afterwards.
Spreading the slurry in the autumn
If slurry is to be spread in late summer, it is advisable to add 20 g of Active NS per m3 of untreated slurry introduced. Remember to agitate the tank vigorously before starting to offload the slurry.
Fast-forming, strong floating crust
To establish a strong floating crust, add 20 g of Active NS per m3 of slurry. If Active NS has been used before, add only 20 g of Active NS per m3 of untreated slurry introduced. Then add 1–2 kg of finely chopped straw per m2 of the surface of the slurry tank. Next, agitate the slurry tank vigorously to mix the sediment and the straw with the slurry. A very strong floating crust will now form, which will prevent the evaporation of ammonia from the slurry tank.
Cattle and circulation flushing
Empty as much as possible out of the channels, then add 20 g per m3 of slurry expected to be found in the channels at the next emptying. Perform circulation flushing at least once every 24 hours, as this makes the slurry more homogenous, increases the nitrogen content of the slurry – and reduces odour.
Start as above. Then add 20 g of Active NS to the exit channel – preferably at the farthest end so that the Active NS mixes with all the slurry that ends up in the slurry tank.
Always vigorously agitate slurry that has had Active NS added to it before starting to offload the slurry. Failure to take this step will result in less than the maximum expected effect.
