Broadacre365 is a remote monitoring app that calculates the daily and cumulative loss of available water experienced by a crop. By utilising root-zone sensors to monitor moisture content, weather sensors for evapotranspiration calculations and combining it with plant-centric, soil and weather models, a prescription called an Irrigation Recipe is then provided to the grower, detailing the precise amount of water required to replenish readily available water for optimal plant growth and health.
