Phosphorus legacy: role of long-term soil phosphorus accumulation in the sustainable management of intensive agroecosystems
(Lincoln University, 2017-08-02)
Phosphorus (P) is an essential nutrient for all organisms. Phosphate rock is primarily utilised for the manufacture of P fertilisers, and is a finite resource. Most agricultural lands worldwide present low levels of available ...
Phosphorus response and efficiency of 12 novel dryland legume species on an acid high country soil
(Fertilizer and Lime Research Centre, Massey University, 2012-02)
High country soils are typically acidic and have low fertility compared with intensive high fertility low land systems. Pasture legumes commonly used in New Zealand perform poorly in these environments. The optimum soil P ...
The performance of an efficient dairy system using a combination of nitrogen leaching mitigation strategies in a variable climate
An efficient dairy system, that implemented a combination of nitrogen (N) leaching mitigation strategies including lower N fertilizer input, standing cows off pasture for part of the day in autumn and winter (stand-off), ...
Transforming soil phosphorus fertility management strategies to support the delivery of multiple ecosystem services from agricultural systems
Despite greater emphasis on holistic phosphorus (P) management, current nutrient advice delivered at farm-scale still focuses almost exclusively on agricultural production. This limits our ability to address national and ...
Nitrous oxide emissions from in situ deposition of ¹⁵N-labeled ryegrass litter in a pasture soil
(Crop Science Society of America, Soil Science Society of America and American Society of Agronomy, 2013-03)
During pasture grazing, freshly harvested herbage (litterfall) is dropped onto soils from the mouths of dairy cattle, potentially inducing nitrous oxide (N₂O) emissions. Although the Intergovernmental Panel on Climate ...
