Methods, systems and devices for mobile detection of soil compaction and soil characteristic data are provided. Operations include causing a subsurface portion of soil at a compaction detection location to be disrupted using compressed air, generating disruption data corresponding to the disruption of the subsurface portion of the soil at the compaction detection location, generating geographic location data corresponding to the compaction detection location, receiving the geographic location data from the location device and the disruption data from the disruption sensor and associating the geographic location data with the disruption data.

A method for a cylindrical device includes semi-helically oriented teeth, knives, or blades radially outward from an outer surface of the cylindrical device or rotor is provided. Each tooth, knife, or blade is part of a row of teeth, knives, or blades. Each row is oriented with an offset angle such that the spirally orientation completes angular offset of about 90° or less. The knives may have sharpened edges that are oriented to cut on different planes as the cylindrical device rotates. The knives may be held in place by holders that have configurations to oriented the knives at certain angles.

A multipurpose agro-farming and gardening machine for earth pit digging, tilling, raking, soil bed preparation on plain terrains, as well as in sloppy terrains in hilly areas, weeding, manuring and seeding, with augers, raking rods, compost or manure and seed drop attachments for use in small farms and home gardening. Machine of the proposed invention comprises three rotary soil excavating augers (7) and a linear actuator (2) for driving the assembly of augers to dig into the soil for making pits or for making trenches with adjoining raised beds. Attachments enable adopt double digging practices for preparation of soil beds, manuring and seeding comprising [i] raking rods with spikes for deep digging and [ii] attachments for compost or manure drop and seed drop.

A tilling apparatus and a method of tilling soils which includes the use of a rotational shaft having a number of cutter assemblies located at spaced apart locations on the shaft in which each cutter assembly has a multitude of blades which rotate as the rotary shaft rotates to form a plurality of spaced apart trenches having the same spacing as the spacing of the cutters, and a width caused by the width of the blades. As the blades dig the trench, the soil contacted by the blades is granulated and is tossed about by the spinning blades so that some soil falls back into the trench and some falls along the periphery of the trench to form rows of aerated granules which promote enhanced growth of plants or seeds in the trench and along the edge of the trench to improve the yield of pasture having the trenches. Various attachments can be provided on the tilling apparatus, either in front of or towards the rear of the spinning blades for different purposes, such as rippers, seeders, levellers, or similar. The advantage of the tilling apparatus is that the soil is formed into granules which are used to form an aerated array of soil granules having enhanced growing properties for plants.

A representative system for preparing a field for planting includes: first disk blades, each exhibiting a first offset angle with respect to a tilling direction; second blades, each exhibiting a second offset angle with respect to the tilling direction; ripper shanks disposed behind the second disk blades; third disk blades disposed behind the ripper shanks, each exhibiting a third offset angle with respect to the tilling direction; fourth disk blades, each exhibiting a fourth offset angle with respect to the tilling direction; and a chopper reel disposed behind the fourth disk blades; wherein, with respect to magnitude, each of the first offset angle and the second offset angle is greater than each of the third offset angle and the fourth offset angle.

A garden tiller is disclosed herein. The garden tiller includes at least one handle portion configured to be grasped by a user; a shaft portion coupled to the at least one handle portion, the shaft portion having a first end and a second end, the second end of the shaft portion being oppositely disposed relative to the first end; and a body portion coupled to the second end of the shaft portion, the body portion including an impact motor configured to drive one or more cultivating teeth for loosening and/or displacing soil, the impact motor configured to apply an impact torque to the one or more cultivating teeth so as to more effectively break up compacted soil.
