Hybrid airship-drone farm robot system for crop dusting, planting, fertilizing and other field jobs

Modern farming is currently being done by powerful ground equipment or aircraft that weigh several tons and treat uniformly tens of hectares per hour. Automated farming can use small, agile, lightweight, energy-efficient automated robotic equipment that flies to do the same job, even able to farm on a plant-by-plant basis, allowing for new ways of farming. A hybrid airship-drone has both passive lift provided by a gas balloon and active lift provided by propellers. A hybrid airship-drone may be cheaper, more stable in flight, and require less maintenance than other aerial vehicles such as quadrocopters. However, hybrid airship-drones may also be larger in size and have more inertia that needs to be overcome for starting, stopping and turning.

Method and apparatus for ultra precise GPS-based mapping of seeds or vegetation during planting

InactiveUS6941225B2Application can be controlledLow costMowersFertiliser distributersVegetationGps receiver
An ultra precise seed planter apparatus and method for generating a centimeter accuracy map of the location of seeds or vegetation as they are planted from an agricultural planting machine. The apparatus is fitted with a GPS receiver feeding a data logger, and optical sensors that are placed adjacent seed or vegetation dispenser. The data logger monitors GPS time and UTM coordinates, as well as the optical sensors. Ground speed and azimuth are also monitored. The seeds or vegetation are time-tagged as they are dispensed, and software is used to process the dispensing time and GPS location data and estimate the exact coordinates of each seed or plant and its distance from adjacent seeds or plants. As a result, a precise planting map is generated. The invention may also be used to determine the location to dispense seeds or vegetation, and activating the dispenser when that location is reached.

Seeding Machine With Seed Delivery System

A seed delivery system for use in a seeding or planting machine that removes the seed from a seed meter by capturing the seed therefrom. The delivery system then moves the seed down to a lower discharge point and accelerates the seed horizontally rearward to a speed approximately equal to the forward travel speed of the seeding machine such that the seed, when discharged has a low or zero horizontal velocity relative to the ground. Rolling of the seed in the trench is thus reduced. Furthermore, as the seed only has a short drop from the outlet to the bottom of the seed trench, the seed has little vertical speed to induce bounce. The delivery system uses a brush belt to capture, move and accelerate the seed. By capturing the seed and moving it from the meter to the discharge, the seed is held in place relative to other seeds and the planter row unit. As a result, the seeds are isolated from row unit dynamics thereby maintaining seed spacing.

Sodium alginate oligosaccharide coated slow-release fertilizer and preparation and application thereof

The invention discloses a sodium alginate oligosaccharide coated slow-release fertilizer. Coated materials of the slow-release fertilizer contain sodium alginate oligosaccharide and an auxiliary coated material, wherein sodium alginate oligosaccharide is composed of two structural units, namely a-L-mannuronic acid and b-D-guluronic acid. The two structural units are linked in three ways by 1,4-glucosidic bond, so as to form a unbranched linear segmented copolymer. The coated slow-release fertilizer is mainly applied in commercial crops, fruit and vegetable crops, grain crops, economic forest, flowers and plants, traditional Chinese medicinal materials, lawn and the like. By introducing organism-derived sodium alginate oligosaccharide into the coated materials of the slow-release fertilizer, nutritive elements required by plant growth and development can be supplemented by a slow-release approach, and the plant growth promoting effect of sodium alginate oligosaccharide also can be performed so as to finally achieve the yield-increasing effect. In addition, a medicament prepared by using sodium alginate oligosaccharide as the main coated material composition is safe and nontoxic and has advantages of low cost, small application amount and the like.

Mobile soil mapping system for collecting soil reflectance measurements

A mobile soil mapping system includes an implement for traversing a field to be mapped, and a reflectance module carried by the implement for collecting spectroscopic measurements of soil in the field. The reflectance module has a light source, an optical receiver for transmitting light to a spectrometer, and a shutter system that alters the optical path between the light source and the optical receiver. The shutter system allows the system to automatically collect a dark reference measurement and a known reference material measurement at timed intervals to compensate for drift of the spectrometer and the light source. A self-cleaning window on the reflectance module has a lower surface maintained in firm contact with the soil during operation. External reference blocks are used to calibrate the system to ensure standardized, repeatable data. Additional sensors are carried by the implement to collect other soil data, such as electrical conductivity and temperature.

Dual capability nurse distribution system

A nurse distribution system provides dual capabilities for planting different seed varieties from a single planting mechanism. The air cart carries two tanks in which different seed varieties can be placed. The nurse mechanism selectively distributes seed from one tank to the on-row singulation meters, yet can switch to the seed in the second tank to correspond to different soil conditions encountered by the planting mechanism. The planting mechanism carries a first line from the first tank to the nurse receiver and a parallel second line from the second tank to the same nurse receiver. By keeping the nurse receiver as small as possible, thus having a small seed reservoir, the seed variety selection can be switched from one tank to the other in an effective manner.

Combined intercropping and mulching method

A method of combined intercropping and mulching of commercial crops is described herein. Suitable annuals such as young wheat and / or buckwheat plants are planted in soil in which legumes were originally planted. A portion of the resulting upper portions of young wheat and / or buckwheat plants is mowed and blended with organic debris to provide nutrients for intercropped commercial plants such as corn and soybeans. The remaining portion is chopped blended with organic debris and sprayed onto the top layer of seeded soil as combination mulch. For larger commercial applications, conventional agricultural machines are described herein, and are modified for the most efficient intercropping.
