Preliminary study of the potential for phosphorus loss with the development of organic soils
(Fertilizer and Lime Research Centre, 2013)
Organic Soils (organic matter concentration > 30%) cover 200,000 ha in New Zealand, of which around 67,000 ha have been converted for intensive land use (viz. dairy). However, Organic Soils have a number of properties that ...
Direct exports of phosphorus from fertilizers applied to grazed pastures
(Crop Science Society of America with the American Society of Agronomy and the Soil Science Society of America, 2019-08-21)
Since its discovery in 1669, phosphorus (P) in the form of fertilizer has become an essential input for many agroecosystems. By introducing a concentrated P source, fertilizers increase short-term P export potential soon ...
Using organic phosphorus to sustain pasture productivity: A perspective
Organic phosphorus (P) in grazed pastures/grasslands could sustain production systems that historically relied on inorganic P fertiliser. Interactions between inorganic P, plants and soils have been studied extensively. ...
Role of organic anions and phosphatase enzymes in phosphorus acquisition in the rhizospheres of legumes and grasses grown in a low phosphorus pasture soil
Rhizosphere processes play a critical role in phosphorus (P) acquisition by plants and microbes, especially under P-limited conditions. Here, we investigated the impacts of nutrient addition and plant species on plant ...
