Fecha de publicación: 23/07/2015 Fuente: Wipo "precision agriculture" A method for prescribing variable seed density planting. The method can include: obtaining first EOS data collected approximately on an estimated day (DOY′) during a past crop-growing season in which NDVI* data most closely resembles a spatial-yield pattern measured during harvest in the past crop-growing season; converting the first EOS data to first reflectance data and first NDVI data; calculating first NDVI* data on a per pixel basis for the first EOS data based on the first NDVI data using satellite scene statistics of the first EOS data; generating an NDVI* map for a first field using the first NDVI* data for the first EOS data; and generating a variable seed density prescription map using the NDVI* map. The variable seed density prescription map can be spatially defined. Other embodiments are provided.
