Described herein are implements and applicators for placement of fluid applications with respect to agricultural plants of agricultural fields. In one embodiment, a fluid applicator for applying fluid to plants in rows in a field includes a frame, at least one applicator arm disposed in a rhizosphere of plants during fluid flow through the applicator, and a fluid conduit connected to the frame and disposed in the row between plants to deliver fluid to the row between plants.

Systems, methods and apparatus for monitoring soil properties and applying fertilizer during a planting operation. Various sensors are disposed in ground engaging components for monitoring soil properties. The ground engaging components may have structure for opening a side trench in the sidewalls of the seed trench and may include liquid application conduits for injecting liquid into the sidewalls of the resulting side trenches.

Described herein are implements and applicators for placement of fluid applications with respect to agricultural plants of agricultural fields. In one embodiment, a fluid applicator for applying fluids to plants in rows in a field includes a frame, a coulter connected to the frame and disposed to open a trench between the rows of plants, and at least one application member connected to the frame or to the coulter and disposed to apply fluid to a rhizosphere of the plants.

A fertilizer boot (10) for a plough assembly (27) including a body (11) with an upper solid fertiliser inlet (12) and a lower solid fertiliser outlet (14) and a passageway between the upper solid fertiliser inlet (12) and the lower solid fertiliser outlet (14), wherein the body (11) has a lower body portion (31) that includes the lower solid fertiliser outlet (14), the lower body portion (31) having outwardly facing sidewalls (33) on either side of the lower solid fertiliser outlet (14), and wherein the sidewalls (33) are at least partially coated with a wear-resistant coating for reduction of wear of the sidewall (33) during use of the fertiliser boot (10) with the plough assembly (27).

An agricultural row unit includes a knife disposed ahead of the gauge wheel for delivering material to soil adjacent to a trench. In one example, an agricultural toolbar includes a frame, a wheel mounted to the frame, and a knife disposed ahead of the wheel and comprising a material delivery conduit disposed on, through, or adjacent the knife.

Methods, systems, and kits are provided for in situ seed treatment with liquid crop benefit compositions at planting in furrow.

According to an embodiment of the present invention, there is provided a plant cultivation device, including: a body part configured such that a growth space in which a soil and plants are accommodated and to which a nutrient solution is supplied and an auxiliary space which is disposed under the growth space, into which air is introduced and through which a nutrient solution supplied to the soil is discharged are formed therein; a fertilization part disposed inside the body part and configured to supply a nutrient solution to the soil; and a separation part disposed between the growth space and the auxiliary space, configured to prevent the inflow of the soil into the auxiliary space, and provided with a plurality of openings having a smaller diameter; wherein the air introduced into the auxiliary space is introduced into the soil through the openings and promotes the growth of the plants.

Methods and systems for generating a plasma-activated liquid or gas, and applying the plasma-activated liquid for agricultural use. A system embodiment includes a hand-held device that can be pointed and directed at different target areas of a plant. A method embodiment includes generating a plasma discharge in a gas environment or a liquid environment, and applying the gas/liquid to a plant.

A swivel bar is operatively connected by a bracket assembly to a toolbar, such that the swivel bar pivots back and forth in the horizontal plane about a pivot. A resilient device is positioned inside the swivel bar where the pivot is combined to the bracket assembly and extends through the swivel bar. At least one agricultural implement and preferably two agricultural implements are connected to the swivel bar on opposite sides of the pivot.

A first biasing element is positioned between an opening unit and a first frame for urging the opening unit downward. A lateral pivot combines the first biasing element to the first frame to allow for lateral movement in a horizontal plane of the opening unit. A first resilient device is positioned between the closing unit and the first frame to allow for lateral movement about a vertical axis of the closing unit and to urge the closing unit back to a neutral position. A second resilient device is positioned between the closing unit and the first frame to allow for vertical movement about a horizontal axis and to urge the closing unit back to a neutral position.
