I think at first you need to identify whether the soil is calcareous, gypsiferous, or salt affected if you are working on arid areas. Then you can go with any normal test tools as per the soil type to identify the fertility status of soil.
As they are both monocots and fast growing, you would need to find out silicates and boron status and N and P are also important but these can be more easily corrected. It has been mentioned above that the type of soil needs to be determined.

Soil fertility refers to the ability of a soil to supply plant nutrients. However, the measurement of the fertility of soils can be calculated by chemical analysis for plant nutrients e.g., N, P, K and trace elements.
