2. Soil Respiration Test - USDA

The best time to run the soil respiration test is when soil moisture is at field capacity (the amount of water the soil can hold after drainage). Otherwise, soil respiration should be measured before and after the infiltration measurement or soil wetting (6 to 24 hours after wetting). Materials needed to measure respiration: 6-inch diameter ringsoil respiration measurement Equipment | Environmental XPRTThe EGA61 is a multi-channel soil respiration measuring system. A single EGA61 system is able to measure as many as 24 soil samples. The operator can easily program the system to measure each channel for a desired period of time before the multiplexer switches to the next sample.Soil Quality Test Kit | NRCS SoilsSoil Quality Test Kit. The Soil Quality Test Kit Guide describes procedures for 12 on-farm tests, an interpretive section for each test, data recording sheets, and a section on how to build your own kit. The NRCS does not build or sell soil quality test kits. Test kits can be purchased from Gempler's or Murray FFA in Murray, Iowa.
