Farmland and Crop Quality Improvement for Heavy Metals Based on Six Sigma

Abstract

Scientific methodology of soil and farmland health management and crop quality improvement is urgent to set up. Our objective was to recognize and sweep away the choke point and improve the farmland health course by applying the philosophy and method of six sigma. Farmland and crop quality improvement for heavy metals belongs to Systems Engineering. SIPOC flux of heavy metals indicates the key process by causal factor analysis through quantitative way. Multi-source and multi-scale data suggest that key process of performance is source control. Measurement processes analyse data and eliminate root causes to improve sigma levels. The study was conducted on farmland and crop health management with concern at the inputs and mechanism that had choke point and high defect rate. DMAIC of sources and exports of cd in the soil will improve and control the Quality of crop and farmland. The premise of implementing six sigma is that the chosen metrics are measurable and effective, but we find a lack of good correlation between terminal index and intermediate index in heavy metal pollution. Suggestion is as follows: Big data could be shared and processed intelligently; policy and culture to pollution-free is more important to farmland and crop health by six sigma.
