Using NDVI and soil quality analysis to assess influence of agronomic management on within-plot spatial variability and factors limiting production

Abstract

This study uses remote sensing technology to map the spatial variability of crop performance within trial fields using conservation agriculture practices. Using zero tillage and residue removal, it is discovered that crop performance is unevenly distributed within the field with lower elevations offering higher performance. However, retaining soil cover allows for uniform distribution of crop performance. Subsequently, the article concludes that maintaining soil moisture is the most important element of the production system and recommends retention of cover for best performance throughout the field.
