Agricultural implement for delivering ammonia gas to soil
First Claim
1. An agricultural implement for delivering ammonia gas fertilizer to the soil of an agricultural field, said implement comprisinga soil cutting device for forming a furrow in the soil to be fertilized,a closing device trailing said cutting device for closing said furrow,an ammonia gas delivery tube extending downwardly into said furrow between said cutting device and said closing device, and then extending rearwardly along said furrow to said closing device for delivering ammonia gas onto at least one wall of said furrow rearwardly of the trailing end of said cutting device and of the leading end of said closing device, anda discharge nozzle coupled to the trailing end of said ammonia gas delivery tube for discharging ammonia gas onto at least a bottom of said furrow, the discharge nozzle being biased downwardly to maintain engagement with the bottom of said furrow.

Abstract
An agricultural implement for delivering ammonia gas to soil includes a soil cutting device for forming a furrow in the soil to be fertilized, a closing device trailing the cutting device for closing the furrow, and an ammonia gas delivery tube extending downwardly into the furrow between the cutting device and the closing device, and then extending rearwardly along the furrow to the closing device for delivering ammonia gas onto at least one wall of the furrow rearwardly of the trailing end of the cutting device and of the leading end of the closing device. A discharge nozzle is mounted on the trailing end of the ammonia gas delivery tube for discharging ammonia gas onto the bottom and/or sides of the furrow. The ammonia gas delivery tube and the discharge nozzle may be made of non-metallic material, such as polymeric material, to reduce or avoid freezing of soil and moisture on the implement.
