— Above a content of 0.8% C, the strength decreases. As the carbon content increases, the proportion of cementite in the steel also increases. Since the cementite is relatively hard, the hardness of the steel increases accordingly. This results in an almost linear relationship between the carbon content and the hardness of the (unalloyed) steel.

selected at each altitude for sampling. Five leaves were randomly collected from the south side of the crowns and measured. After felling, leaves and branches were sorted according to their age (1 and 2 years old for leaves and 1–4 years old for branches). Fully mature leaves of the present growing season were regarded as 1-year-old leaves.

In our guide to the Carbon: Nitrogen ratio, we took an in-depth look at the role of the essential nutrients in composting.. As discussed there, you CAN compost with a wide range of C: N ratios. Moreover, while you can calculate exact ratios, it's complex, time-consuming and probably far more involved than the average home composter needs to worry about.
