Growing energy willow “Salix viminalis energo”

Description: The energy willow or Salix viminalis "Energo" is a species of willow which proved to be the most efficient plant cultivated for energetic purposes. This willow has a volume of timber of 40-60 t / ha dry material and a very high calorific value of approx. 4900kcal/kg, higher than that of oak. The energy willow is used in the form of briquettes and pellets. This willow is characterized by very rapid growth, rapidly regenerating its annual harvest. In addition to high speed growth, energetic willow planting is done very easily, as it is not a demanding plant. Planting the willow is done by means of cutting and planting branches, and it is required only once every 25-30 years to achieve annual crops. It can be planted on any soil (considering that it even helps to stop landslides), but a fertile soil and crops can prove more efficient.

The planting costs are between 1500-2000 euros / ha (investment is made only once for a harvest of 25-30 years) and in the first year there is only a modest harvest obtaining about 10 t / ha with profits of between 300 -400 euros / ha, but the next year after the harvest, it is to reach 40-60 t / h, increasing profits between 1500-1800 euros / ha/year.

Resources needed: - rigorous documentation regarding the characteristics of its planting and harvesting
                             - Availability for a lot of land
                            - Acquisition cost depending on the desired area to be planted
                         - Availability / rent equipment for the annual harvest
Advantages: - Environmentally friendly
                - Once invested, it is regenerated annually.
                - It is a tree that can be planted on any land (even swampy soils) with a resistance to temperature and weather variations.
                - It comes as a renewable and cheap energy solution
                - High calorific value (4900kcal/kg)
                - Once planted, annual profits are obtained, with minor costs.
                - It is more profitable than the use of land for vegetable growing
Disadvantages: - if you opt for the cultivation of large areas, the investment with the acquisition of cuttings can be very high (documentation regarding funding opportunities with EU funds)
Conclusions: In many countries the plant is grown in large quantities (such as Sweden), considering it is an alternative energy product easily obtained and at low prices. In some countries the multitude of agricultural land (or the one that can not be used for agriculture) may be used for this purpose, especially as the international interest in this area is growing.

Worm farm

Description: Such an activity is not intended for trading product for fishing, but for marketing the soil resulting from the process of raising the worms. The selling price of such soil arising from a production is about 5 EUR / kg. There are currently no fertilizers on the market that are more natural and more nutritious than this. It can be used both for gardens (one needs about 5-8 kg of fertilizer per 100 square meters of garden, with better results than any other product), as well as for potted plants. Worm farms can be made on a small scale (in simple containers or on a floor) or by restricting large scale to the ground + a sorting arrangement (designed to create a separate the worms from the soil).

The soil will be populated with common red worms, and regarding their diet, any residue will do, both food and non-food, with the specification that you should avoid high fat foods (meat, cheese) or high acid foods (citrus, onion family vegetables). We present below three simple ways to organize a good worm farm.

1. Organizing a simple small-scale farm:

2. Double storey farm organizing:

3. Organizing large-scale farm on the ground + an example of the screening process:

Resources needed: - Setting up  the method
                             - Availability of space outside the city / unincorporated land
                             - Expenses related to acquisition of the worms or their picking
                             - Expenses related to the construction / farm land itself (farm should be constructed so as to maintain a level of moist)

Advantages: - very small investment
                - It can be a very productive activity
              - The process is static, the worms do all the work, the only effort is the sorting of the soil from the worms.
                - Benefits as the product itself is far superior than the alternatives on the market
                - Fans of this activity are calling the soil black gold, as its price is high compared to the simplicity of the process.
Disadvantages: - The activity is not recommended to people with phobias on this topic
                      - Work may become really messy
                      - It can not be held indoor for various reasons
Conclusion: If you have a property of any land outside the city and you have no stomach issues on such subject, such business can be extremely profitable.
