Within-field yield stability and gross margin variations across corn fields and implications for precision conservation

Abstract Soil spatial variability is a primary contributor to within-field yield variation across farms. Spatio-temporal stability and can be assessed through multi-year monitor data geostatistical techniques. Our objective was delineate zones using coupled with gross margins plan precision conservation prescriptions. This study employed corn measurements from 2018, 2019, 2020 farm economics compile margin maps for nine Texas Blackland Prairie fields, identified nonprofitable areas in each field that may unsuitable crop production. Yield were delineated mean coefficient of (Zone A: high yield, stable; Zone B: unstable; C: low D: stable). Approximately 57% the area fields classified as unstable and, nearly 29% yielded consistently below D). Gross ranged − $693 $775/ha. Stability A B generally had positive margins, whereas C D negative margins. Based on assessment, zone could removed row As part Long-Term Agroecosystem Research Network Common Cropland Experiment, production (fields Y-8 Y-13) or received reduced inputs (field SW-16 W-13).
