Abstract

The acid deposition, as well as the direct effects of the air pollutant gases is causing serious damages to the forest ecosystems. The nitrogen principal compounds were monitored at the Station for the Global Atmospheric Watch (GAW), in La Palma, Cuba, to obtain the atmospheric deposition of the principal compounds of the nitrogen. It is appreciated changes from 13,3 kg-N.ha-1.año-1 to 44,8 kg-N.ha-1.año-1 during the years 1985 to 2008. The result was that the nitrogen oxidant forms represent about 25 % and the humid deposition depends on the characteristics of the precipitations of our tropical climate. The ammonia and ammonium are the most important elements in our tropical conditions. Some of the nitrogen compounds present trend to increase of concentrations. Also the depositions of these compounds via atmosphere produce effects in the feedback of phenomena as the acidity of soils and the atmosphere. It is recommended to maintain a systematic and integrated monitoring, to know the possible damages to the agriculture and the forests.
