Fertilizer container for sprinkler system
First Claim
1. A fertilizer applicator for a sprinkler system, comprising:
- A. a screen for holding solid fertilizer;
B. a screen holder for containing the screen, including;
i. integrally formed upper and lower end flange members and sidewall elements joined thereto, the said elements providing openings for water to pass therethrough at a controlled rate and dissolve the fertilizer, the lower flange member being perforated to permit water to drain therethrough; and
,ii. a bottom support member for the screen, the support member having a plurality of sized openings to permit dissolved fertilizer to pass therethrough at a controlled rate;
C. a case member, including;
i. a sidewall portion for enclosing the screen holder and contained screen therein;
ii. the case member being removeably secured to the upper flange member of the screen holder, thereby spacing the sidewall of the case member and the sidewall elements of the sreeen holder;
iii. the case member providing inlet and outlet means for water and diluted fertilizer solution, respectively;
whereby,i. water fed into the inlet will be pressured between the sidewall of the case, through the sidewall elements of the screen holder and into the screen to dissolve the fertilizer;
ii. water draining from the perforations in the lower flange member will dilute the dissolved fertilizer solution to reduce fertilizer burning; and
,iii. when the solid fertilizer is dissolved, water is passed principally through openings of the bottom support member and the outlet of the applicator, and then to the sprinkler system.

Abstract
A container for solid fertilizer is provided, the container being inserted into a sprinkler line system. The container provides a screen to hold the fertilizer and permits water to permeate therethrough. The screen and fertilizer are secured within a screen holder having continuous or perforated side walls, depending on the type of solid fertilizer to be used, and a gapped bottom support for the screen.
Water from the sprinkler is fed into the container and is pressurized through the screen and dissolves the fertilizer. The rate of solubilization depends on the water flow, the type and solubility of the fertilizer, and the size of the perforations in the screen and gaps in the screen holder.
