The point is that if the food is not meat we need like up to 75% less crops, which is completely attainable without synthetic fertilizer.

That land use figure includes grazing areas, not just crop fields.

Every addition of a new consumer in a food chain brings with it a high rate of energy loss. The cow will need to use its energy to live, only a small portion of the energy is left in the steak you eat. 75% is a good approximation.

In general, the shorter the food chain, the more efficient it is. This is a universally known fact. I will drop some helpful links for you if you doubt this:
