Traditional pastoral grazing systems in New Zealand are under increasing scrutiny regarding their potential influence on the environment. Regenerative Agriculture systems are promoted as a potential solution. In addition, diverse sward mixes containing more than 10 species have been suggested as a management solution to reduce environmental footprint and improve animal productivity. To scientifically evaluate these opportunities, a long-term dairy and sheep farmlet study is underway at Massey University, Palmerston North, New Zealand. It involves three treatment groups including: i) perennial ryegrass/white clover sward under conventional management; ii) a diverse pasture sward under regenerative management; and iii) a diverse pasture sward under conventional management. This three-year PhD programme will examine aspects of soil phosphorus availability and plant uptake under the different treatments and will explore key plant, microbial and soil factor influences on phosphorus availability. Students will be working in a large team of multi-disciplinary scientists, technicians and other post graduate students to undertake their research.
The PhD programme includes an annual stipend of NZ$30,000 in addition to covering student fees. The programme is suited for a candidate with an Honours or Masters qualification in Soil Science or related disciplines. The aim is to have the successful candidate on site by June 2023.
