Fertiliser co-operative Ravensdown has reduced its urea price by $44 a tonne in line with softening global prices.
The new domestic price puts urea at $745 a tonne.
Sales manager Ross Aimer said the co-operative altered the price as global prices had been falling.
"There are several reasons for this including the prospect of increased capacity from large new urea plants in Saudi as well as the improved access to large gas reserves in the United States."
The costs of phosphate rocks have increased and Ravensdown has avoided passing this on to farmers by managing blends to hold the price of superphosphate.
Meanwhile, more than 90 South Island farmers have attended seminars looking at the latest research on the use of nitrification inhibitors on pasture to reduce nitrate leaching into waterways.
The seminars on the product developed by Lincoln University and Ravensdown were presented by professors Keith Cameron and Hong Di.
The technology reduces nitrate leaching and greenhouse gas emissions, makes more nitrogen available for pasture growth and cuts costs.
Initially Cameron and Di focused their research on nitrate leaching resulting from the application of fertiliser to pasture, but saw the main source of nitrate leaching and nitrous oxide emissions was urine patches in grazed pasture.
The change of focus led to the development of technology to apply the nitrification inhibitor dicyandiamide to pasture soils.
Eco-n works by slowing the effectiveness of bacteria in the soil. The bacteria converts ammonium into nitrate, which can leach into waterways, and nitrous oxide which is released into the atmosphere. Fairfax NZ
