What should we know about the biological agriculture?
The biological agriculture is an intensively developing sector in the rural economy of Europe. It encloses 4.4 million hectares of land and 155 thousand farms. Irrespective of these figures, it is just about 2% of total agricultural production and 3.2% of arable land of the Community. The tendency shows an accelerated development, which has to reach a growth of 10% annual production of agricultural biological produce by 2005.
The biological production is manufacturing biological produce by using a new technology connected with standards, which guarantee the quality required for this production.
The standards are periodically renewed and published. However, they are not obligatory and suggest the basic framework on which each country develops its own standards and technological requirements. These developments are entered in the regulations of the notion “biological production”through the specific technology of production, but some national particularities are also considered.
As regards the biological production, the SOIL holds a high position:
It requires much more special care for maintaining and recovering its fertility. It is explained by the fact that the use of mineral fertilizers is inadmissible in this type of agriculture, and the balance of nutritive substances is obtained by natural fertilizers and improving agents, which maintain and recover the structure and fertility.
IMPROVING agents are:
- Shavings, which improve the aeration.
- Micro organisms in the form of preparations, which improve the structure.
- Special improving substances – lombri compost, green fertilizing, extract of kelp.
