Growing energy crops provides a range of benefits.
Growing energy crops for the AD industry has many advantages beyond conventional cropping of farmland.
The process of Anaerobic Digestion produces two main products: biogas and digestate. Digestate can be described as the remaining by-product after the process has taken place. Digestate can vary in is composition and is greatly affected by the feedstock used within each different digester. Digestate can be categorised either as Acidogenic or Methanogenic. Put simply Acidogenic digestate is the solid state digestate and Methanogenic being the classed as the liquid digestate or “sludge”. Both forms of digestate have different properties and are used in contrasting ways as a result.
Working in conjunction with one of the largest AD plants in Europe we have exclusive access to over 90,00 cubic metres of methanogenic digestate per year. Derived from totally organic feedstock which includes: maize, grass, rye & wholecrop barley, in this form digestate has many uses and has a higher nutritional content than its acidogenic cousin. Typically high in nutrients such as ammonia, nitrates and phosphate, organic methanogenic digestate offers a broad spectrum of nutrients and trace elements providing a source of nutrition for current cropping whilst offering long term soil enhancing properties for subsequent cropping. Working with growers we aim to offer various spreading options including: injectors, dribble bar and cultivator. Utilising lagoon space where available and offering temporary storage when permanent storage is not available.
A cost analysis of digestate vs artificial fertiliser can be seen below.
Advantages of using digestate
High level of readily available nitrogen, circa 80% compared to 55% of cattle manure.
No deployment licence required
Low pathogen levels, reducing disease burden risk.
Broad spectrum of nutrients and trace elements, reducing the number of additional passes required.
Very fast acting, has an immediate effect on crop condition, for excellent crop response.
Replaces reliance on mineral fertiliser applications and the price volatility associated with artificial fertiliser.
