Poultry litter is a mixture of droppings, feathers, bedding material, feeds and water in the chicken coop after cleaning.

The nutrient concentration of the litter depends on the type and amount of bedding material, poultry kept, number of birds, the nutrients included in the poultry diet and the age of the chickens. It is advisable to collect this litter once after every two weeks.

Strategies should be used to ensure that it does not get into water courses.

Poultry litter is profitable for use either as manure or animal feed since it minimises cost and maximises total nutrient input.

While it might appear suitable for direct garden use, domestic poultry litter is generally unsuitable for this purpose. This is because if used fresh, it could burn plant roots, attract vermin and rodents.

Store well the litter to use it as fertiliser and minimise health and pollution risks. Pile it in an open small stack not more than 1.8m high to reduce loss of nitrogen and organic matter due to overheating.

The site should be well-drained and away from water courses and fenced to keep off livestock.

Compact the base of the stack to reduce chances of coming into contact with surface water. Store the litter for shorter periods, in amounts that meet the needs of the current growing season. This will help maintain the material’s nutrient value and reduce environmental risk and liability.


Composting may reduce the risk of nutrients from poultry litter entering water courses, thus, cutting the weight and volume of the original material. Composted poultry litter is a more valuable fertiliser than fresh litter. Heap the litter in rows of about 1.2m high and 2.4m wide to achieve temperatures of 60°C to 70°C or simply add a 5cm layer to every 15cm of the other material.

Composting normally increases cost and time required for processing, but reduces the total amount of nitrogen and organic matter available during land application. The composted material can be used in nurseries, gardens and flower farms.


Fertilising all types of pastures: It can be applied to mixed pastures comprising grasses and legumes. Do not graze pastures for at least three weeks after spreading poultry litter to allow regrowth period on a well-grazed paddock.

Application can be done by broadcasting, followed by cultivation into the soil where possible to reduce smell and loss of nitrogen into the air. Do not apply litter on steep land.

Fertilising fruit crops and vegetables: This can be applied at the rate of 150g per square metre for most crops. Additional potassium fertiliser may be needed. Note that fresh poultry manure is known to harbour pathogens, therefore, it is crucial to mitigate the possibility of vegetable
