Brazil-Tocantins

Overview

Crop identification and Crop Area Estimation:

  • Cropland
  • Crop types
  • Agricultural systems : level of intensification : crop livestock forest integration; crop rotation; cropping patterns; agroforestry systems.

Note: To support the Brazilian Low Carbon Agriculture Program (ABC Program)

Crop Condition/Stress:  not at the moment

Soil Moisture: not at the moment

Yield Prediction and Forecasting: not at the moment

Crop Residue, Tillage and Crop Cover Mapping:

  • Different types of soil management (no-tillage systems, convention systems) as indicators of different cropping systems.

Site Description

Landscape TopographyDominance of the topographic modeled type A: Areas with mild relief, slightly undulating with soft slopes (declivity equal to or less than 5%) in which, in most soils, the runoff is slow or medium. Subdominance of the topographic modeled type B: Areas with sloping surfaces (declivity greater than 5% and equal or less than 10%), usually with undulating relief, in which the runoff, for most soils is medium or fast.
Typical Field SizeMostly large (fazendas with fields of ~ 100 ha), and some smallholders
Climatic ZoneTropics, warm

In Situ Observations

Land Use Cover

  • Crop Type(s):
  • Collection Protocol:

    Land use and land cover observations were carried out following the JECAM field data collection guidelines. 256 GPS waypoints were collected during the land use survey using the high resolution Landsat 8 image of the 28th of July printed in an A1 format for tracking the observations. Attributes of the database include centroid position, date of entry, land use information (Crop/ non crop, cropping pattern) and georeferenced photo ID.
