Disclosed are improvements relating to injection of water-absorbent polymers, including a blend containing fine granules, using one or more air-blown, plowblade applicators. The process creates a "blanket" of moisture-retaining particles for the plant roots. A further aspect of the invention includes drawing a plowblade through the soil at an appropriate shallow angle and speed to establish a wave in the soil, together with the use of a deflector and control over the air pressure, all of which maximizes diffusion and distribution of the injected particles.
