system components, organization, socio-economic

Land use is a classification criterion determined by
use categories specific to our country and the type of
management different in one category of use or the
other. According to this criterion agroforestry systems
are classified in: I) agroforestry systems in the forest
fund, classified themselves in: i) intimately mixed
cultures; ii) forestry corridors - source of animal feed
mass; II) agroforestry systems in the agricultural
fund, classified in: i) intercropping; ii) field protection
forest belts, water course protection forest belts; iii)
forest-pastoral systems (pastures with trees); iv)
agroforestry-pastoral systems. This classification
takes into account the different environmental
conditions and priority production, forestry in the first
case and agricultural in the second. The mentioned
agroforestry systems are also the most common
combinations of the three components. Some of
them have been practiced in our country over
time and continue to be practiced, although in a
less organized manner, others, such as forestry
corridors - source of animal feed mass and
intercropping in agroforestry sense, are news for
our country.
3. Characteristics of the main
agroforestry systems
3.1. Intimately mixed cultures
Intimately mixed cultures are agroforestry systems,
which consist of agricultural species growing among
forest species rows of young plantations in order to
achieve maintenance, diversification of production
and improve soil properties (fig. 1). Therefore, in long
term, the main objective of this agroforestry system is
achieving timber production in less time and of better
quality.
Through the maintenance of crops forest cultures
benefit from more maintenance than usual and, in
some cases even additional water intake (when crops
are irrigated). Also, by maintaining crops within the
system and implicitly the forest cultures is resolved
the issue of labor in forestry, difficult to procure for
forestry work. Crop yields that are obtained in this
agroforestry system can compensate labor costs, but
also contributes to increasing rural incomes.

Combination of agricultural species and the forest
cultures is done from plantation installation until the
latter reach their massive state. It is done in forest
plantations installed in large planting schemes (from
2.00 x 1.00 m to 7.00 x 7.00 m) to enable the
mechanization of maintenance and / or harvesting of
crops.
