Abstract
The use of broiler chicken manure is increasing in Sweden due to its reputation as a quick-acting nitrogen fertiliser.
However, data concerning the effects on crops and the environment are limited.
In 1998, a field trial was carried out at Ultuna with the aim of investigating the effects of spreading two different quantities of pelleted and stored broiler manure to iceberg lettuce and white cabbage.
The parameters studied were yield, plant nutrient utilisation and amount of soil mineral nitrogen.
Results from the field trial show that the pelleted broiler manure gave a better effect on yield than stored broiler manure.
Nutrient balances showed that it is difficult to attain a good balance between application and uptake of nutrients when using broiler manure, especially pelleted.
Soil samples indicate that the amount of mineral nitrogen in the soil after harvest did not differ significantly between the two broiler manures at the two levels of application.
The results from this first year of field trials need to be confirmed with further trials.
