Methods, structures, devices and systems are disclosed for solarizing soil using a moveable optical focusing array. In one example, an apparatus to solarize soil from a moveable platform includes a vehicle, an array of mirrors located on the exterior of the vehicle, in which the mirrors are steerable to control the orientation of the mirrors to direct sunlight to a spot on soil that generates heat to a solarize the soil, and a sensor coupled to the vehicle to measure the temperature of the soil, in which the orientation of the mirrors is determined based at least in part on the measured temperature to control the temperature of the soil.
