A powdered scent compound and related methods of application for adhering the powdered scent compound to a desired application area. The powdered scent compound can comprise a porous carrier powder, an adhesive compound and a synthetic scent compound. The powdered scent compound is shelf-stable and convenient to apply, carry and store. Furthermore, the powdered scent compound can adhere to applied surfaces, thereby ensuring that powdered scent compound remains where it is applied, even in locations where the potential exists for the compound to drip or be blown from.

A system for dispensing low rate agricultural products, includes a syringe-based agricultural product metering system, at least one agricultural product tube, and an agricultural product metering system. The agricultural product metering system is operably connected to a source of low rate agricultural products. The agricultural product tube is operatively connected to the agricultural product metering system. The agricultural product metering system is configured to dispense liquid low rate agricultural products at a low rate defined as below 3.7 fluid ounces per 1000 row feet.

The present disclosure relates to agriculture. The teachings thereof may be embodied in methods to determine a percentage of weeds and/or control device. For example, a method for determining a weed percentage in an observation section of a field may include: acquiring actual spectral information using an optical observation section sensor aimed at the observation section; acquiring reference spectral information using an optical reference sensor aimed at a reference section of the same ground area; determining a difference between the actual spectral information and the reference spectral information; and mapping the difference to the weed percentage using predefined mapping.

The present invention relates to a system for locally precise application of substances to useful areas of farmland and woodland and a corresponding method. The system comprises at least one multiple rotary wing aircraft, which contains at least one electronic control device for controlling the flight movements, which steers the multiple rotary-wing aircraft autonomously on predefined flight paths. The electronic control device contains at least one processing unit, at least one receiver for signals of a global satellite navigation system for position determining and an inertial measurement unit for detecting movement data of the multiple rotary-wing aircraft. The processing unit calculates the data of the receiver according to the method of real-time kinematics with the data of a base station and with the measured data of the inertial measurement unit for improving the accuracy of the position measurement data so that the electronic control device can sufficiently accurately steer the multiple rotary-wing aircraft to apply substances to farmlands.

An apparatus for biological control of agricultural pests and for reducing damage to crops. The apparatus includes a container for holding biological organisms or material. The container also includes first and second ends and an opening formed at the first end for receiving the biological organisms. The apparatus has a dispensing port disposed at the second end for dispensing the biological organisms over a target location. The apparatus further includes an auger, driven by a motor and having a plurality of spiral like wire brushes, said auger mounted to and driven by a first motor; a spreader motor mount having a motor mount holding area for holding a second motor, the spreader motor mount having a motor mount connection area for connecting to the second end; and a spreader agitating device used for spreading the biological organisms or material over the target location.

A spreader assembly may include a hopper configured for receiving a spreadable material, a removable cartridge configured for sliding engagement with the hopper and having a material transportation mechanism configured for receiving the spreadable material from the hopper, and a spreader configured for receiving the spreadable material from the material transportation mechanism and spreading the spreadable material onto a target surface. One of the hopper and the cartridge may include a roller having a roller surface, and the other of the hopper and the cartridge may include a bearing surface configured for rolling engagement with the roller surface. The cartridge may have one or more pull bars to facilitate removal of the cartridge from the hopper. Related methods are described.

An apparatus for biological control of agricultural pests and for reducing damage to crops is disclosed. The apparatus includes a rotatable container for holding biological organisms or material. The walls of the container include a series of openings through which the biological organisms or material can pass, dispersing the biological organisms or material over a target area when the container is rotated.

The present invention is directed to an applicator having an agricultural product pneumatic conveying system which meters particulate material from one or more source containers at the application equipment and transports the particulate material to evenly distribute the particulate material from the applicator. The pneumatic conveying system employs large diameter supply lines connected between the metering devices at the source containers and delivery nozzles, where the supply lines operate to move and mix the particulate material from the source containers to the nozzles. The particulate material is metered from the source containers into the supply lines via a number of airlocks that can be operated without allowing airflow from the large diameter supply lines to enter the source containers through the airlocks. In addition, the metering devices can b e operated in collective or independent variable manners to allow for sectional control and turning compensation.
