The effect of diverse pasture and Italian ryegrass on urine patch size and plant nitrogen uptake
(Lincoln University, 2016-11-15)
The intensification of the dairy industry in New Zealand has prompted the use of fertiliser and legumes to produce productive pastures with high nitrogen content. High quality pastures create an imbalance between nitrogen ...
The fate of nitrogen in an animal urine patch as affected by urine nitrogen loading rate and the nitrification inhibitor dicyandiamide
(Lincoln University, 2014)
The animal urine patch is the main source of nitrogen (N) loss from agricultural grazed pasture systems. Losses include emissions of nitrous oxide (N₂O), a potent greenhouse gas, and leaching of nitrate (NO3-) into ...
Effect of plantain (Plantago lanceolata L.) proportion in the diet on nitrogen use, milk production and behaviour of lactating dairy cows
(Lincoln University, 2017-02-07)
Expansion and intensification of dairy in pasture based systems whilst economic, creates environmental challenges through nitrate leaching and degradation of water quality. With pressure to reduce nitrate leaching and ...
The effect of alternative forage species and gibberellic acid on nitrate leaching
(Lincoln University, 2017-02-24)
Nitrogen (N) leaching from soil is a significant concern for intensively grazed forage-based systems because it can cause a decline in water quality. Urine patches are the main source of N leaching in these systems. In New ...
Effect on nitrate leaching of plant N uptake in the perimeter of a urine patch
(Lincoln University, 2016-11-14)
Intensification of New Zealand’s grazed pasture systems over the past decade has brought focus upon the negative impacts of agriculture on the environment. The important issue of nitrate leaching losses is currently driving ...
