Embodiments of a method and a system are provided to create a uniform layer of a substance such as a hydrogel or other fluid substance underneath the soil surface with minimal or little surface disturbance to the plants, the plant roots and the soil located on or slightly below the applied surface area. It is to be clearly understood that various different embodiments may be employed to deliver a variety of different substances to the soil, and such substances may be gels or liquids. The presently preferred fluid substance is currently a hydrogel, and the present illustrated and described embodiment may be employed to inject hydrogel into soil but other fluid substances may be injected as well.

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.

Implement apparatus may be configured to displace ground material. For example, an implement may include an extension member coupled to a roller apparatus. The extension member may be coupled to a mounting apparatus configured to mount each of a crumbler, a hipper, a bermer, a bermer, crumbler combination apparatus, or a chopping apparatus.

A scarifier for raking and loosening soil includes a frame having a base plate and configured to rotate about a central axis, a rod coupled to the base plate and arranged centrally to the base plate and extending in an axial direction and adapted to be inserted inside the soil to support the scarifier and at least one tool coupled to the base plate and configured to extend inside the soil to loosen the soil.

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 machine that allows for processing the plant as much as the area where the plant requires and makes the seed bed ready for planting at once and in a single process, for plants planted in the range of 45-70 cm, such as corn, cotton, beet, sunflower, and beans in agricultural areas.

A knife for a cylindrical rotor includes at least two sharpened edges adapted to cut materials during land clearing or mulching. The knife further includes a top surface and a bottom surface wherein the knife is shaped as an inverted frusto-square pyramid. The knife may further include a tapered sidewall defining one sharpened edge. The angle may be about 30 to about 60. The knife may have four sharpened edges. The knife further may include an aperture that may be equidistant from the four sharpened edges. The knife is adapted to be moved when one sharpened edge becomes dull. The knife may further include a conical countersunk aperture. The knife may have a thickness of about to about .
