Description Rainwater contains nutrients and can, in a low-input situation, constitute an important
nutrient source for crop production. During 1981-90, rainwater was collected using standardized
collection procedures at tbree different locations at ICRISAT, Patancheru, Andhra Pradesh.
Samples were analysed for N, P, K, S, Ca, Mg and Na. Ion concentrations were low and varied
from year to year. The mean pH was 7.05. Because the locations were close to each other, there
was no significant. variation in tbe composition of rainwater among tbe locations. There were
negative correlations between the amount of rainfall and the chemical parameters. Phosphorus
was positively correlated witb N, K, S, Ca, Mg and Na. Patancheru is highly industrialized and
its atmosphere will have a bearing on the composition of rainwater. Sulphur fertilizer response
experiments should not be carried out at tbis location. On an average, rainfall at this location
contributes, per hectare, 5.8 kg N, 0.4 kg P, 4.8 kg S, 1.7 kg Ca, 1.7 kg Mg and 10.5 kg Na. The
increase in N, P and S contribution was higher during 1986-90 than in 1981-85.
