Canada-CFIA

Overview

Goals of the site in terms of:

Crop Identification and Crop Area Estimation
Crop Condition/Stress
Soil Moisture
Yield Prediction and Forecasting
Crop Residue, Tillage and Crop Cover Mapping
Soil Properties

Project Objectives

Estimation of Biophysical Variables

Operational Implementation Plan

Similar approach, the main experimental site will be planted in corn; the second sites continue rotation of corn, soybean, and wheat. We do not anticipate destructive sampling in other fields because there is no more funding to support this activity. However, we will deploy available longbar fAPAR, PASTiS-PAR, and PASTiS-57 sites in representative fields as resources allow.
