STUDIES ON THE EFFECT OF ACID PRECIPTATION ON SOIL FERTILITY

This paper concludes the following aspects:The results of field inves-tigation on acid rain harmful to the soils and plants;The different res-ponses of soils and plants between the irrigated and spraied by the simul-tant acid rain;The changes of the constituents and properties of soiland percolate in the processes of leaching soil column with simultant acidrain;The vegetables response in yield and quality to the acidificationsoil after having been leached by acid rain in ten years'rainfall;The pHstability of soil and its acid capacity under the condition of being acidi-fied by the simultant acid rain or by various kinds of acid;The dynamicevidence of the mechanisum of soil acid buffer;The predict of soil aci-dification process and countermeasure studies.
