An opener attachment for an agricultural row unit including a frame, an arm pivotally coupled to the frame, an opener disc coupled to the arm and configured to excavate a trench into soil, and a gauge wheel coupled to the arm and configured to block movement of the opener disc into the soil to control a depth of the trench. The opener attachment also includes a mechanical stop coupled to the frame and configured to block the gauge wheel and the opener disc moving toward the soil. In addition, the opener attachment includes an air bag configured to urge the gauge wheel and the opener disc toward the soil.

A fertilizer knife for applying fertilizer to soil. The fertilizer knife includes a knife body having a primary chamber through a rearward end thereof. Fins diverge laterally outwardly from a tip at a lower forward end of the knife body and curve upwardly from the lower forward end, terminating above a discharge end of the primary chamber. Liquid from a liquid source is communicated to the primary chamber and is discharged from the discharge end into the furrow formed by the fertilizer knife. In another embodiment, a secondary passage through the knife body communicates gas from a gas supply into a gap surrounding a supply tube disposed within the primary chamber. In another embodiment flow controllers disposed on the knife regulate liquid into the primary chamber and gas into the secondary passage.

A trough is cut in the ground surface by a rotating member. The rotating member displaces soil upward with respect to the ground surface and rearwardly with respect to a direction of travel of the rotating member. While the soil is in the air, slurry is deposited into the trough. The soil is then redirected downward to the trough to cover the slurry with the soil.

A liquid dispensing apparatus for applying liquid products to row crops. The liquid dispensing apparatus includes a plurality of drop assemblies supported by and laterally spaced along a boom structure. Each of the drop assemblies includes dribble hoses for dribbling a liquid product onto the soil in a rhizosphere of adjacent crop rows. The drop assemblies may include a spray assembly for spraying the row crops. The dribble hoses may be supported by a base unit with positionable support brackets

A fertilizing device has at least one of the tubular body, and the tubular body is inserted in the soil in which the plant is planted. The tubular body has a containment space inside and a plurality of through holes on its surface. The tubular body is provided with at least first separated section at its top, and a number of second separated sections among the through holes. When the tubular body is inserted into the soil around the plant, the first separated section of the tubular body is exposed, and the second separated sections are configured for adjusting the spacing between the through holes. When the fertilizer and moisture are introduced into the containment space through the top of the tubular body, the fertilizer and moisture are discharged through the through holes of the tubular body, so that the fertilizer and water can penetrate into the deeper soil more evenly and the plant roots and soil can absorb nutrients and water more completely.

An agricultural applicator, that applies material to an agricultural field, includes an on-board, real-time image sensor that senses targets for the material to be applied. A controller controls applicators, such as nozzles or other applicators, to apply the material to the sensed targets

A farming machine includes one or more image sensors for capturing an image as the farming machine moves through the field. A control system accesses an image captured by the one or more sensors and identifies a distance value associated with each pixel of the image. The distance value corresponds to a distance between a point and an object that the pixel represents. The control system classifies pixels in the image as crop, plant, ground, etc. based on the visual information in the pixels. The control system generates a labelled point cloud using the labels and depth information, and identifies features about the crops, plants, ground, etc. in the point cloud. The control system generates treatment actions based on any of the depth information, visual information, point cloud, and feature values. The control system actuates a treatment mechanism based on the classified pixels.

Abstract: Disclosed is a liquid nutrient spreader and liquid nutrient spreader system. The liquid nutrient spreader system can include a spreader unit that can be moved in a direction of movement by a mover, which can be a tractor. The spreader unit can be mobile, being supported on the ground by wheels or tracks. The spreader unit can include a frame that supports a hose reel onto which is reeled a supply hose. The supply hose provides for fluid communication of liquid nutrients between a liquid nutrient storage unit to a fluid distributor, and eventually to a one or more of a plurality of injectors mounted to an incorporation toolbar.
