In beardon/ninja-active-mapper: Maps actively measured NDVI from passively measured NDVI imagery

Creates a variable rate nitrogen application image based on Nitrogen Rich Strip (n_rich_strip), Farmer/Target (farmer_practice), Growing Degree Days (GDD), and active_ndvi(Target).

Description

Creates a variable rate nitrogen application image based on Nitrogen Rich Strip (n_rich_strip), Farmer/Target (farmer_practice), Growing Degree Days (GDD), and active_ndvi(Target).

Usage

zero_check_variable_rate(
  yld_fert_field,
  yld_ptnl_field,
  yld_ptnl_zero_check,
  Napp,
  grain_N = 0.024,
  NUE = 0.6
)

Arguments

yld_fert_field	Unfertilized yield prediction for field (kg/ha)
yld_ptnl_field	Fertilized yield prediction for field (kg/ha)
yld_ptnl_zero_check	Fertilized yield prediction for field (kg/ha)
Napp	fertilizer applied prior to sensing (kg/ha)
grain_N	expected grain Nitrogen concentration (fraction)
NUE	Nitrogen use efficiency (fraction)

Value

Variable nitrogen rate recommendation using the zero check strip algorithm
