The red soils of China are highly weathered, inherently infertile
and very susceptible to erosion. However, they represent China's
last available soil resource that could be brought into
agricultural production, a fact that assumes great importance in
view of China's huge and still-increasing population. These soils
are typical of similar red soils that occur throughout tropical and
sub-tropical South America, Africa and south east Asia, so that if
the red soils of China could be successfully utilized then this
would have wider implications for agriculture in other countries.
Previous attempts to cultivate Chinese red soils have met with
little success and it has become apparent that they cannot sustain
arable cropping systems without the most careful management.
This book describes recent research outlining the physical,
chemical and mineralogical nature of the soils, the various
constraints that combine to inhibit their practical use, and the
traditional and novel approaches that may be used to overcome these
constraints. Building upon previous work and using examples from
other countries, the book illustrates these approaches, shows
appropriate land uses for the red soils of China and how the
fertility of the soils evolves with time under these land uses.
Whether these technical and scientific advances will be taken up by
the Chinese farmer will depend to a large extent on the prevailing
socio-economic conditions.
Agriculture is a crucial component of the economies of many of the
countries in transition from a centrally-planned to a market
economy and the sector is by no means immune to the environmental
and socioeconomic problems confronting the countries as a whole.
The concept of sustainable development provides a convenient
framework for the formulation of government environmental policy
for such countries, especially those of them that aspire to join
the EU and would thus be expected to meet EU environmental
standards. For agriculture, this inevitably involves appropriate
strategies for balancing crop and animal production while
protecting the quality of the national soil and water resources.
There is thus an urgent need to compile, exchange and evaluate
current information on the quality of soils in these countries, and
to assess the potential impact of new management practices on the
soil and on the wider environment.
