Protein per unit area
Edible protein per unit area for various foodstuffs:
| Food | Protein | |
|---|---|---|
| (g/m²) | (lb/acre) | |
| Soybean | 40 | 356 |
| Rice | 29 | 260 |
| Maize | 24 | 211 |
| Legume (all non-soybean legumes averaged) | 22 | 192 |
| Wheat | 15 | 138 |
| Milk | 9.2 | 82 |
| Egg | 8.5 | 76 |
| Meat (all meats averaged) | 5.0 | 45 |
| Beef | 2.2 | 20 |
Interpretation
Soybean provides the largest amount of protein per unit area. Soybeans, as a legume, produce essential amino acids such as lysine and fix their own nitrogen, so it doesn't have to be added as a chemical fertilizer in large amounts.
