Nutrient dispersal device

Claim 1

A nutrient dispersal device comprising a hollow body section having an upper and lower end and having apertures in sidewalls of the body section, a cap section rotatably connected to the upper end of said body section, said cap section containing at least one aperture of a predetermined diameter to allow liquids entrance into said body section, and a hollow tip section rotatably connected to the lower end of said body section, characterized in that said nutrient dispersal device further comprises a single storage chamber formed from said hollow body section and said hollow tip section, said storage chamber extending from said cap section to a lower end of said hollow tip section, said storage chamber being of uniform diameter from said cap section to the lower end of said hollow tip section, flotation means contained within said single storage chamber for rising in conjunction with the liquid level within said single storage chamber and for sealing said cap aperture at the time the liquid level within said single storage chamber rises to the level of the cap aperture, said flotation means consisting only of a single spherical float being of a diameter less than said uniform diameter and greater than predetermined diameter and arranged to rise in conjunction with said liquid level from the lower end of said tip section to said cap aperture, said tip section being of a first diameter and said body section being of a second diameter, said second diameter being less than said first diameter, whereby said apertures in the sidewalls of the body section are not blocked upon vertical insertion of said nutrient dispersal device into the soil.
