The 'Express®' willow variety features

One of the most pressing problems of nowadays is the rapid run out of the traditional energy sources, as well as the specially high pollution problem that it causes.

Researchers are concerned that one the most important objective is the search for alternative energy sources. This mission is not easy because the goal is to find a replacement for the well-known, and high-energy content gas and petrol, wich is much more environment friendly.

One thing everyone agrees on,
the new energy source must be affordableenvironmentally friendly and available to anyone. Guided with these principles our company began breeding and testing new varieties, which lead to the following result:

 

Energiafűzek

 

 

The  'Express' willow  (Salix alba L. cv. Corvinus) is a special breed of the common White willow.

It is a tree shaped variety. When applying the proper managament method, it is also suitable for short rotation coppices (SRC) and for industrial wood production plantations.

Especially noteworthy is its great environmental adaptation ability when compared to other willows. For instant, it tolerates drought extremely well.

 

 

 
 
Excellent, above average wood production,
 
which can reach 100 tonnes/ha green Biomass within 2 years! As a fast growing energy plantation, we recommend harvesting every second year. Furthermore, up to 10 rotation periods are possible. 
 
This comes to a total of ca. 1,000 tonnes of green biomass during the 20 years of its life cycle.  

 

Comparative experiments have proven that the 'Express' willow produces far more volume compared to the Swedish, Polish or other Hungarian varieties, and based on comparative tests made on the same habitat with some poplar clones such as the AF2 - we have also recorded recorded faster growth!

    

 

It's also suitable for round wood production purposes, with a rotation period of 5 to 10 years.

 

Amongst willows, the 'Express' variety is the most suitable for quality industrial wood production due to its high wood to bark ratio. 

It must be underlined that the 'Express' white willow is exceptionally suitable for coppicing energy plantations (SRC), and also for roundwood production purposes.

Advantages of the 'Express' willow:

  • applicable for plantations of different purposes 
  • as industial wood plantation it produces roundwood, being a tree shaped willow - rotation period: 5-10 yrs.
  • as energy crop it has an outstanding production: 100 green t/ha/2 yrs.
  • ca. 5 cm yearly growth in diameter  
  • excellent coppicing ability
  • see its produciton here 

 

Burning features

The combustion of most tree species is between ca. 13-14 MJ/kg - measured at 50% moisture content. Related to absolut dry matter content this value is about 17-19 MJ/kg. This means that the differences between two tree species or varieties are below 5%. The Express willow's burning analysis was done at the University of West Hungary, and the tests showed the following values: 17,85 - 18,04 MJ/kg.  

In terms of burning features, the high wood to bark ratio is also an advantage.

 
 
 
 
VARIETY PROTECTION
 
The Silvanus Group Ltd. holds the 'Express' willow's variety rights. It is a registered, patent protected variety. Its propagation material can be produced only in our registered production sites.
