Land cultivating systems and methods utilizing high-pressure fluid jet cutting techniques

A seeding method comprising:

• generating a high-pressure fluid jet within a fluid jet cutting head such that the high-pressure fluid jet follows a first path toward soil positioned below the fluid jet cutting head;
• cutting through a layer of stubble between the soil and the fluid jet cutting head using the high-pressure fluid jet;
• forming a furrow in the soil with the high-pressure fluid jet;
• and
• routing an additive along a second path through a liquid injector nozzle separate from the fluid jet cutting head and toward the furrow formed in the soil, wherein the additive includes at least one of:
• an insecticide, a wetter, a fungicide, an herbicide, and a fertilizer;
• routing a seed along a third path through a cut in the layer of stubble formed during the cutting step, and into the furrow.
