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 includes at least one applicator arm, a first nozzle disposed to apply fluid to a rhizosphere of the plants, and a second nozzle disposed to apply fluid between the row of plants.

Systems for delivering biological products are provided. The biological products may be delivered, for example, to a field. The systems may include a container (110, 210, 310) for holding the biological product. The systems may also include a fluid flow unit (120, 220, 320) configured to subject the biological product to flow from within the container along a fluid flow path (115, 215, 315). Methods of delivering biological products are also provided.

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.

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).

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.

Liquid nutrients are continuously applied to a first group of rows of standing crops by pulling a drag hose from a reel located at one end of a field and between two crop rows with a boom having one end pivotally connected to an applicator and a tractor. The boom provides a liquid supply line from the drag hose to the center or one end of the applicator. At the opposite end of the field, the tractor and applicator turn 180° while the boom pivots to project from one end of the applicator to the drag hose. The tractor returns down adjacent rows back to the first end of the field with the boom projecting to the drag hose while the reel simultaneously retracts the hose between the two crop rows. The reel is moved axially to a third group of rows, and the steps are repeated.

Described herein are implements and application units for placement of fluid applications with respect to agricultural plants of agricultural fields. In one embodiment, an application unit includes a frame to be positioned in operation between two rows of plants and a plurality of flexible members coupled to the frame in operation such that the plurality of flexible members guide a lateral position of the frame to be approximately equidistant from the two rows of plants based upon whether at least one flexible member of the plurality of flexible members contacts one or more plants of the two rows of plants. The plurality of flexible members include a plurality of fluid outlets for spraying crop input in close proximity to the rows of plants.
