A method enhances soil by preparing a microbial solution with microbes, a growth medium, and water; iteratively and selectively breeding generations of microbes to arrive at a predetermined microbial solution in a concentrated form of at least 110.sup.7 cfu/ml (colony-forming units per milliliter); adding humic acid with amino acids and protein to support an active microbial population to support active and healthy plant growth; and storing the microbial solution as a solid for enriching the soil with micronutrients, microbial cultures and organic materials.

Systems and methods are disclosed to provide a plant nutrient by selecting a microbial solution with predetermined characteristics for agriculture use; iteratively and selectively breeding generations of microbes for microbial strain selection with predetermined microbial gene profiles to arrive at a predetermined microbial solution in a highly concentrated form of at least 110.sup.7 cfu/ml (colony-forming units per milliliter), wherein multiple single microbial series are separately cultivated and followed with cross cultivation among the microbial series in a specific sequence; and mixing by-products produced by the crossly cultivated microbial series with humic acid and a filler.

Systems, methods and apparatus are provided for modifying a position of crop input application. In some embodiments, a positioning control actuator modifies a position of liquid application relative to a seed.

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.

An agricultural tillage implement has a vertical tillage section and an aerating section behind the vertical tillage section, each extending substantially perpendicular to the pull direction of the implement. Individual vertical tillage elements, such as disc blades, can be indexed with individual rotary tine assemblies of the aerator section so that discrete holes formed by the aerator section are positioned between substantially continuous slits formed by the vertical tillage section. A ground deposit system is provided for depositing a component on the ground and may be configured for conducting and depositing a granular component, such as seeds, fertilizers, minerals or the like, or liquid components, such as liquid manure.

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.

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 at least one applicator arm that is actuated by an actuator to move the applicator arm from a position in the row between plants to a position adjacent to the plant.

A fluid injection system includes a container and fluid injection device. The fluid injection device includes a housing having a flow tube having an inlet end and an outlet end. A shroud is positioned between the inlet end and the outlet end and has a first end and a second end defining a ramped surface therebetween. The shroud redefines at least a portion of the fluid pathway as a constricted fluid pathway. A diverter port is between the inlet end and the shroud and diverts a portion of the inlet fluid into the container. An injection port is between the shroud and the outlet end and receives product from the container. The first end of the shroud includes a step defining a notch in fluid communication with the diverter port. The second end defines a recess in fluid communication with the injection port.

A fluid injection system includes a container, fluid injection device and a fertigation basket. The fluid injection device includes a housing having a flow tube having an inlet end and an outlet end. A shroud is positioned between the inlet end and the outlet end and redefines at least a portion of the fluid pathway as a constricted fluid pathway. A diverter port is between the inlet end and the shroud and diverts a portion of the inlet fluid into the container. An injection port is between the shroud and the outlet end and receives an injection tube. The fertigation basket holds dry product which is dissolved into the container to be drawn out of outlet end via the injection tube.

A method for treating plants comprises estimating a growth state or maturity state of a plant based on a planting date, a current date and the crop type of the plant. A root zone estimator or data processor estimating a size, diameter or radius of a root zone of the plant based on the determined growth state or maturity state. The data processor adjusts a lateral offset of a distribution pattern of a crop input or nutrient from at least one nutrient knife based on the size, diameter or radius of the root zone and safety zone about the root zone, where the at least one nutrient knife tracks a path outside of or bounded by the root zone.
