Database from a production field under continuous agriculture
Description
A database from a wheat (Triticum aestivum L.) production field (60 ha) under continuous agriculture, located in south-eastern Pampas, Argentina.
Usage
wheat
Format
A data frame with 5982 rows and 7 variables:
- x
X coordinate, in meters
- y
Y coordinate, in meters
- CE30
apparent electrical conductivity taken at 0–30 cm
- CE90
apparent electrical conductivity taken at 0–90 cm
- Elev
elevation, in meters
- Pe
soil depth, in centimeters
- Tg
wheat grain yield
Details
Coordinate reference system is "WGS 84 / UTM zone 20S", epsg:32720 Wheat grain yield was recorded in 2009 using calibrated commercial yield monitors mounted on combines equipped with DGPS. Soil ECa measurements were taken using Veris 3100 (VERIS technologies enr., Salina, KS, USA). Soil depth was measured using a hydraulic penetrometer on a 30 × 30 m regular grid (Peralta et al., 2015). Re-gridding was performed to obtain values of all variables at each intersection point of a 10 × 10 m grid.
