after sampling. After every harvest, we collected two soil samples at 0–20 cm and
20–40 cm depth for physical and chemical property analysis. The Research Centre
Hanninghof, Yara International, Dulmen, Germany, analysed contents of macroand micronutrients in samples from the soils, maize stover, rice straw and their
grain. Various agronomic data were also recorded including plant height, cob length,
grain yield (Mg /ha at 14% MC) and whole stover biomass (Mg DM/ha) for maize
and tillers/m

and whole straw biomass (Mg DM/ha) for rice. In this chapter, however, only whole
maize stover and rice straw chemical nutrients in terms of macro- and micronutrients and biomass yield are presented and discussed.
