Review Crop rotation, a way to a sustainable rice production
Main Article Content
Abstract
agronomy is a tangible reality; rice monoculture ruins soil
fertility, helps pests, diseases, weeds, causes soil salinization
and non profitable harvests. Since rice is the basic diet in
Cuba, its production and marketing is a vital necessity, that is
why thousands of people in our country are dedicated to it
and each day more people get involved with this work,
specially producers in need of having peak harvests but do
not protect the soil as the main productive medium, which is
quickly emproverished. However, there are some
phytotechnical methods, such as crop rotation, addition of
green manures, the use of chemical amendments and others
that just in case they are applied, they will stop this process
and turn those ills into benefit for the own producers and the
society. Stopping the causes of a bad work is a necesity that
cannot be postponed, the special agronomic management
given to rice crop leads inexorably to the deterioration of its
agroproductive qualities. As an answer to the problem and a
possible solution, this work summarizes the main results
related with crop rotation that have been obtained in �??Los
Palacios�?� Rice Research Station, Pinar del Rio, which prove
that it can be possible and there is plenty of time to recover
the lost fertility and achieve stable, sustainable and profitable
productions.
