a first irrigation system for supplying water to an agricultural area, the first irrigation system comprising: a first plurality of valves; a first plurality of sprinkler heads; and a first set of pipes for placing the first valves into fluid communication with the first sprinkler heads; a second irrigation system for supplying non-water chemicals to the agricultural area, the second irrigation system comprising: a second plurality of valves; a second plurality of sprinkler heads; and a second set of pipes for placing the second valves into fluid communication with the second sprinkler heads; and a storage tank partially located underground, the storage tank being in fluid connection with the second irrigation system via a one-way valve, the storage tank being configured for storing and supplying the non-water chemicals to the second irrigation system; wherein the second set of pipes are isolated from the first set of pipes via a three-way valve, such that the non-water chemicals in the second set of pipes cannot mix with the water in the first set of pipes. ### Claim 2 (depends on 1) The fertilizer system according to claim 1, wherein the first controller controls both the first irrigation system and the second irrigation system. ### Claim 3 (depends on 1) The fertilizer system according to claim 1, further comprising: a second controller; wherein the first controller controls the first irrigation system and the second controller controls the second irrigation system. ### Claim 4 (depends on 1) The fertilizer system according to claim 1, wherein the first set of pipes and the second set of pipes are both buried in a common set of trenches. ### Claim 5 (depends on 1) The fertilizer system according to claim 1, wherein the first set of pipes and the second set of pipes are buried in separate sets of trenches. ### Claim 6 (depends on 1) The fertilizer system according to claim 1, further comprising: at least one first elongated leach line coupled to the first set of pipes for watering an extended agricultural area. ### Claim 7 (depends on 6) The fertilizer system according to claim 6, further comprising: at least one second elongated leach line coupled to the second set of pipes for providing the non-water chemicals to the extended agricultural area. ### Claim 8 (depends on 1) The fertilizer system according to claim 1, further comprising: at least one light emitting diode (LED) operably associated with at least one of the second plurality of sprinkler heads, the LED being activated during operation of the second irrigation system. ### Claim 9 (depends on 8) The fertilizer system according to claim 8, wherein the LED remains activated for a selected period of time after operation of the second irrigation system. ### Claim 10 (depends on 8) The fertilizer system according to claim 8, further comprising: an electrical power source for providing power to the LED. ### Claim 11 (depends on 10) The fertilizer system according to claim 10, wherein the electrical power source is a rechargeable battery. ### Claim 12 (depends on 1) The fertilizer system according to claim 1, further comprising: at least one warning device operably associated with at least one of the second plurality of sprinkler heads, the warning device being activated during operation of the second irrigation system by the flow of water through the second irrigation system. ### Claim 13 (depends on 12) The fertilizer system according to claim 12, wherein the warning device is a rotating mechanism carried by the at least one sprinkler head. ### Claim 14 (depends on 13) The fertilizer system according to claim 13, wherein the rotating mechanism includes portions having alternating colors.
