Description

Fertilizer makes plants grow faster and produce more. It can be made in the Portable Composter or Advanced Composter.

Performance

Each fertilizer is made from 3 ingredients, which can be any combination of biomass, decayed food or food (raw or cooked). When more than 3 ingredients have been added to a composter, the fertilizer will be based on the average of those values. Each type of ingredient have their own effect on the end result.

The following data was collected on tomatoes only:

Fertilizer	Number of uses	Tomato growth speed, planting to mature	Tomato yield (seeds and produce)
none	n/a	616 seconds1	2
3 biomass	7	416 seconds1	4
3 raw food	3	314 seconds1	5
3 decayed food	3	279 seconds1	4
1 biomass + 1 raw food + 1 decayed	3	314 seconds1	4
2 biomass + 1 raw food	4	349 seconds1	4
2 biomass + 1 decayed	4	336 seconds1	4
2 decayed + 1 biomass	3	311 seconds1	4
2 raw food + 1 biomass	3	327 seconds1	5
1.5 raw food + 1.5 biomass	4	330 seconds1	5

• 1: The recorded times varies with a few seconds for unknown reasons. However, two plants of the same type that was planted exactly at the same time will always mature at exactly the same time, as long as their access to light is equal. The grow times were measured using grow lights only (no sunlight). The growth times were recorded by using a Stop Watch (from Kit(Music)) and an Integrated Circuit (IC10), starting at Hydroponics Device Slot 0 "Occupied" = 1 and stopping at Hydroponics Device Slot 0 "Mature" = 1.

Producing decayed food

The following conditions gave the shortest decay times.

• Gas: X
• Pressure: <0.2 kPa
• Temperature: >200 °C
• Cooked food decays slightly faster than raw

A Fridge Small can be used instead of building a room with this type of atmosphere. Gas at very low pressures can't be heated by a Pipe Heater, the gas should be heated before reducing its pressure.

Base growth times for a selection of plants

The recorded growth time is not exact, it varies with a few seconds during each measurement for unknown reasons.

Plant	Growth time
Fern	616 seconds
Darga fern	925 seconds
Rice	340 seconds
Tomato	617 seconds
Potato	618 seconds
Soybean	620 seconds
Wheat	620 seconds
Corn	766 seconds
Pumpkin	849 seconds
