Digestate Spreading


Digestate spreading is increasingly in-demand in the UK. There is a growing recognition that this method of fertilisation benefits the crops and saves farmers money, through avoiding them having to spend a lot of money on artificial fertilisers. This is also beneficial for the environment.

Tramspread are experts in handling both digestate and slurry and provide a wide range of umbilical slurry spreading equipment. We also run our own contracting operation, providing services to farms in Suffolk, Cambridgeshire and all across East Anglia.

Advantages of Digestate Spreading

With the fast expansion of AD plants in the UK, digestate spreading is becoming increasingly popular as an alternative to slurry spreading.

As a proven organic fertiliser, digestate is a valuable improver for soil and helps to grow better crops. It is produced via the process of anaerobic digestion (AD), together with biogas, so farmers who have an AD facility to produce energy will produce digestate at the same time. Digestate can be produced by breaking down materials such as silage and slurry from livestock, as well as surplus feed. It can either be separated out into fibre and liquid, or used as “whole” digestate, which is of a similar consistency to slurry.

The main nutrients which digestate contains are nitrogen, phosphate and potash. Additionally, there are small amounts of other beneficial elements to help keep the soil in good condition. Its high nitrogen content means it is suitable for using as a replacement for artificial fertiliser containing nitrogen.

The level of nutrients in different types of digestate will vary, however. So it is important either to carry out testing before applying it to the soil or to get full information from the supplier if the digestate is being brought in from outside your own farm.

Choosing Spreading Equipment

Like slurry, digestate can be applied by an umbilical system which allows it to be accurately targeted. This means it is pumped into the field and spread via an umbilical hose. A range of different applicators can be used, with the best choice depending on the type of digestate. Broadcast spreaders work better with fibre, while many other types of equipment, such as trailing hoses and trailing shoe, are more suitable to use with liquid or whole digestate.

Tramspread supplies the full range of equipment for digestate and slurry handling, including pumps, mounted umbilical hose reelers and hoses. We also supply a wide range of umbilical applicators which are ideal to use with digestate as well as with slurry. This includes twin nozzle booms to ensure the digestate is spread evenly, as well as many different models of dribble bars with a range of application rates.

Tramspread can build systems to fit your specific application, and supplies equipment from top international manufacturers such as Bauer, Joskin and Vogelsang, as well as supplying RECK slurry mixers and other specialist equipment. In addition to supplying equipment to buy, we also offer a range of items for hire.

Tramspread’s Work as a Digestate Spreading Contractor

Suffolk-based Tramspread work as contractors, spreading hundreds of thousands of cubic metres of digestate and slurry each year. We supply our contracting services to farms in Norfolk, Hertfordshire and all over East Anglia.

Before spreading, we test digestate for its nutrient value to work out the right amount to apply. Our contracting equipment is configured to ensure accurate application, with our 24m dribble bars placing the fertiliser on the ground in a way which minimises loss of nutrients, while at the same time keeping odour to a minimum.

As well as testing, we use high-tech flow monitoring to show the flow rate during slurry or digestate spreading. Our contracting operation also includes full field mapping and recording, so that farmers have a full picture of exactly how much fertiliser has been applied.
