Key Equations

$$\text{C}:\text{N}:\text{P} = 106:16:1$$
$$(\text{CH}_2\text{O})_{106}(\text{NH}_3)_{16}(\text{H}_3\text{PO}_4) + 138\text{O}_2 \rightarrow 106\text{CO}_2 + 16\text{HNO}_3 + \text{H}_3\text{PO}_4 + 122\text{H}_2\text{O}$$
$$f = \frac{\rho_{\text{NO}_3}}{\rho_{\text{NO}_3} + \rho_{\text{NH}_4}}$$
$$N^* = [\text{NO}_3^-] - 16 \times [\text{PO}_4^{3-}] + 2.9$$

Equations are rendered with MathJax in the PDF with professional LaTeX typesetting.
