Abstract:

Soil quality index (SQI) is an effective method for assessing soil’s capacity for crop production and other ecosystem services. SQI can be used to determine if soil quality is aggrading, sustaining, or degrading. Soil quality assessment includes: (i) characterizing the overall agro-ecological functions of soil by selecting some key soil properties (physical, chemical, and biological) as indicators, (ii) measuring these properties, and (iii) scoring and calculating SQI. The objectives of this research were to assess SQI using the scoring function analysis, and calculate carbon sequestration. The SQI calculated and correlated with the crop yield for the selected sites in the Mid-western Region of the US will be discussed.
