Practically all the soils of Bais are locally considered to be excellent 

 sugar producers, and the same fact is indicated by chemical analysis, 

 they being especially rich in potash and lime and somewhat above 

 the average in phosphoric acid and nitrogen. As in Ilog-Cabancalan, 

 much of the lime is present as the carbonate. Apparently, Bais has 

 an abundant yearly rainfall, as I am informed that the cane there 

 hardly ever suffers from drought, the only complaint being that in 

 especially wet years, cane growing in the 'Tiamakan" soils is apt to 

 be injured by the abundance of water, which does not filter well through 

 the heavy clay subsoil. To obviate this danger it is customary to 

 commence plamting rather early, so as to finish before March at the 

 latest, and get a good stand of cane before the onset of the rainy season
