The primary resources used in organic and conventional tomato
production in suburban Beijing included renewable (e.g. land and
water) and non-renewable (e.g. fossil fuels) resources. Compared to
the conventional farming system, the demand for non-renewable
energy resources in the organic tomato system was 31.50% lower,
whereas water depletion was 1.73% higher. The land area for
organic production was 177 m2 per ton, 29.98% more land
compared to conventional tomato production (Table 4).
