Soil quality is defined as the ability of soil to function as an essential living system within
land-use boundaries. The quantification of soil quality under agricultural systems to estimate …

A 34-day functional test was conducted in Johnson Space Center's Variable Pressure
Growth Chamber (VPGC) to determine responses of a wheat stand to reduced pressure (70 …

To establish a Bioregenerative Life Support System (BLSS) in lunar or Mars bases in the
future, manned stimulation experiments including several kinds of creatures are needed to …

This paper discusses the development of a distributed control system for low-pressure plant
growth chambers using microcontrollers, a computer, and a process gas chromatograph …

Plants grown on long-term space missions will likely be grown in low pressure environments
(ie, hypobaria). However, in hypobaria the transpiration rates of plants can increase and …

Finding a way to categorise crop types using the Vote Classifier algorithm rather than the
Random Forest approach is the main goal of this research effort. Research Tools and …

Plant growing and insect breeding experiments in the CICS (Closed Integrative Cultivating
System) were carried out. The CICS was established for collecting experimental data to …

Reduced atmospheric pressures will likely be used to minimize mass and engineering
requirements for plant growth habitats used in extraterrestrial applications. This report …

Biological life support systems based on plant growth offer the advantage of producing fresh
food for the crew during a long surface stay on Mars. Greenhouses on Mars are also used …

Successful crop production is vital to manned missions to Mars. Plants play integral roles in
conceptual life-support systems as sources of food, oxygen, and waste treatment …
