45	Soil-Cultivation Unit and Soil-Cultivation Method for Conservation-Type Soil Cultivation	US15303223	2015-06-18	US20170105331A1	2017-04-20	Thomas Herlitzius; Andre Grosa; Tim Bögel
The invention relates to a soil-cultivation unit, comprised of a tractor (21) and a driven soil-cultivation machine or comprised of a tractor (21) and a passive, pulled soil-cultivation device (22) for conservation-type soil cultivation, having an equipment carrier with cultivator tools for accommodating one or more cultivator tines (6), characterized in that a regulation unit (23) is provided that accesses data that is recordable before and after travel over the work area in the work process and during the work process, control elements (10) are provided, via which the cutting geometry of the cultivator tines (6) can be adjusted, the regulation unit (23) is set up in such a way that control variables can be generated from the recorded data for setting the cutting geometry during the work process, and the cutting geometry of the cultivator tines (6) is can be permanently adjusted during the work process as a result of the control variables that are generated. A corresponding soil-cultivation method is described.
46	Robotic platform and method for performing multiple functions in agricultural systems	US13837786	2013-03-15	US09288938B2	2016-03-22	Kent Cavender-Bares; Charles C. Bares
An autonomous vehicle platform system and method configured to perform various in-season management tasks, including selectively applying fertilizer, mapping growth zones and seeding cover crop within an agricultural field, while self-navigating between rows of planted crops and beneath the canopy of the planted crops on the uneven terrain of an agricultural field, allowing for an ideal in-season application of fertilizer to occur once the planted crop is well established and growing rapidly, in an effort to limit the loss of fertilizer.
