A survey comparing regeneratively and conventionally managed pastures and farm management policies
A pasture and farm management survey was conducted on thirteen geographically paired regenerative and conventional beef and sheep farms in the upper North Island to identify differences in pasture attributes and management practices. Farms were paired by geographical location and livestock type. When compared to conventional pastures, regenerative pastures had a similar number of grass, legume and broadleaf species (averaging 4, 1 and 3 species respectively), three times as much legume (13 compared to 4% content) and 30% less perennial ryegrass in total DM (P<0.01) but a similar broadleaf content. There was no difference between pasture types in pre- or post-grazing covers. Compared to conventional pastures, soils sampled from regenerative pastures had a higher pH, and herbage had higher levels of calcium, boron, molybdenum (P<0.05) and a trend towards lower Olsen P values (P=0.052). There was a divergence between farm types in fertiliser policies, with regenerative farmers generally not using synthetic nitrogen (N) and phosphorus (P) products and applying a wider range of nutrients. Herbicides and pesticides were used across both farm types. Changes in pasture composition (i.e., less perennial ryegrass and more clover) and soil nutrient status were consistent with lower N and P inputs on regenerative farms.
