Brief description
Description of the effect on leaching (positive or negative)
of N and P 5
One of the crucial factors in the management of livestock manure is the capability to storage the manure
during the year to achieve the possibility to supply the crops when it is most needed. Examples of storage
facilities are primarily big concrete tanks, where manure can be stored (typically capacity of 5oo to 5.000
m3). These storage tanks are very simple, but the level of investment is fairly high.
It is possible to install a tight fitting cover on most tanks, primarily to prevent emission of ammonia and
odour.
For solid manure, the storage facilities will be manure pits.
By being able to store livestock manure safe during periods
of the year where it is not appropriate to spread manure in
relation to the need of the crops, as would achieve a
significant reduction in leaching of nutrients to the
recipients. It is very unfortunate to spread manure
especially in winter, since at this point no crops are
growing to absorb nutrients, and nutrients may potentially
be leached.
Also during the summer, it is not appropriate to spread
manure, if the sole purpose is getting space in a storage
tank which does not have sufficient capacity and at the
same time no crop with fertiliser needs.
A proper storage management of manure will in itself have
a great effect in preventing point source hot spot pollution.
