Scientists Use Technology to Track Carbons

Plant pathologist G. Brett Runion is conducting the research with plant physiologist Stephen A. Prior and research leader H. Allen Torbert.

The scientists are using cylindrical, open-top field chambers to expose growing crops to varying levels of atmospheric CO2. Measurement of soil and plant responses to rising CO2 enables the scientists to understand how to manage agricultural systems to increase the amount of carbon stored in plant residues and soil.

Increased carbon storage has multiple benefits, such as reduced soil erosion and compaction, increased water-holding capacity for plants and a slower rise in atmospheric CO2 concentrations.

Runion is also using a system called ACES--for "automated carbon efflux system"--to track carbon as it flows from soil to atmosphere.

Currently the group is using ACES to compare the effects of CO2 on conventional and conservation tillage systems for a sorghum-soybean crop rotation.

TITLE: SCIENTISTS USE TECHNOLOGY TO TRACK CARBONS

ALAM BA NINYO NA ISANG URI NG TEKNOLOHIYA ANG GINAGAMIT NG MGA SIYENTISTA PARA MATUKOY ANG CARBON SA ATING MGA LUPANG SAKAHAN AT MAGING SA ATING KAPALIGIRAN?

ITO AY TINATAWAG SA PANGALANG “ACES” – AUTOMATED CARBON EFFLUX SYSTEM, NA SIYANG GINAGAMIT NG MGA EKSPERTO SA PANGUNGUNA NI PLANT PATHOLOGIST G. BRETT RUNION, KATULONG SINA PLANT PHYSIOLOGIST STEPHEN PRIOR AT RESEARCH LEADER ALLEN TORBERT.

ANG PAGGAMIT NG ACES AY NAGLALAYONG MALAMAN ANG EPEKTO NG CARBONDIOXIDE SA CONVENTIONAL AT CONSERVATION TILLAGE SYSTEMS.

SA NGAYON, ITO AY GINAGAMIT NG MGA EKSPERTO SA ESTADOS UNIDOS SA PAGTATANIM NG SORGHUM-SOYBEAN CROP ROTATION.

SAMANTALA, ANG INCREASED CARBON STORAGE SA MGA LUPANG SAKAHAN AY MERONG IBAT-IBANG BENEPISYO TULAD NG KABAWASAN SA PAGKAKAROON NG SOIL EROSION AT COMPACTION, MAS MATAAS NA WATER-HOLDING CAPACITY PARA SA MGA TANIM AT MABAGAL NA PAGKAKAROON NG ATMOSPHERIC CARBONDIOXIDE CONCENTRATIONS.
