Once slurry has been tested and its nutrient status established, it may be possible to reduce purchased input requirements, while still providing optimum nutrients to support high levels of crop performance.
Treating slurry with an inoculant can increase available nitrogen content by up to 20%, as well as reduce the amount of ammonia released into the atmosphere. The enzymes and bacteria in inoculants will also help improve fibre breakdown during storage. This allows the carbon contained within the fibre to be incorporated into soil more rapidly and be taken up more quickly by plants.
Incorporating organic materials, such as slurry, into soil also plays an important role in increasing overall levels of organic matter. This can have important agricultural and ecological benefits, such as reducing fertiliser requirements, improving soil condition, and increasing biological activity within the soil.
Taking a balanced approach to nutrient management and maximising natural resources will build systems that are resilient to both environmental and economic change.
