			An alternative way to think about the problem is by considering the space taken by a fermenter. Each fermenter takes up 6-12 plots of space depending on layout. 4 fermenters fully loaded with biomass take up 48 plots + 17.76 (rounded to 18) plots for switchgrass growth. In order to be more efficient, corn/watermelon production would need to saturate a single fermenter (12 plots) with 180 crops/hour. This leaves 66 plots available for plants, which need to produce 180 crops/hour for a minimum of {{Overline\|2.\|72}} crops/hour, ruling out corn entirely as it can't achieve the equivalent production even with no area taken by fertilizer production. Unfertilized wheat can produce {{Overline\|28.\|4}} fertilizer/h for a total of 56 cycles.

			Watermelon needs 50 plots, leaving 16 plots available for fertilizer production, which themselves need to produce at least 60 cycles of fertilizer/h (more if using fertilizer on fertilizer-producing plants). Mixing in a small amount of hay, fertilizer effectiveness can be increased, but not by enough to overcome a more compact fermenter arrangement as reducing space taken by each fermenter to ~9 plots is enough to nullify the advantage if power consumption is not priced in.

	From the conversion rate table, Pareto-optimal plants are Switchgrass (highest harvest after conversion to biomass), Corn (Highest unprocessed harvest), and Watermelon (Highest output/h on max yield fertilizer). A fermenter takes 20 seconds to process an item for a total of 180 items/hour, potentially diminishing the effectiveness of ~~Switchgrass~~. However, ~~fertilizer~~ production requirements introduce overhead.		From the conversion rate table, Pareto-optimal plants are [[Switchgrass]] (highest harvest after conversion to biomass), [[Corn]] (Highest unprocessed harvest), and [[Watermelon]] (Highest output/h on max yield fertilizer). A fermenter takes 20 seconds to process an item for a total of 180 items/hour, potentially diminishing the effectiveness of switchgrass because the output of as little as 5 plants is enough to saturate a fermenter. However, [[Fertilizer]] production requirements introduce overhead.

	Because Hay is counted as biomass instead of food, it contributes towards growth cycles when used in an [[Advanced Composter]]. As such, max yield fertilizer production is best done using Wheat as input stock.		Because Hay is counted as biomass instead of food, it contributes towards growth cycles when used in an [[Advanced Composter]]. As such, max yield fertilizer production is best done using Wheat as input stock for food.

	An advanced composter consumes 180 items/hour and 1.2 kmols of water to produce 60 fertilizer, 3kmol of Nitrogen and 3kmol of Methane. Stacks of fertilizer with different properties can be merged to achieve a mixture of ratio properties after fertilizer production, but at this point no analysis has been made on whether this achieves better production per plot.

	In order to get a rounding to 2, the yield boost needs to be 1.5 or above. As such, the minimum yield fertilizer proportion required to achieve a yield boost of 2 is 1/3rd. Any additional food results in less throughput.
