“…Results such as those summarised by Woodcock are the essence of a philosophy first recorded by Connell (1931) and emphasised through later publications (During 1961(During , 1962(During , 1972Blackmore et al 1969;Edmeades et al , 1982O'Connor & Mansell 1982) that lime is not a substitute for fertiliser and that priority should be given to correcting nutrient deficiencies.…”

“…Lime application can directly influence pasture production. Relationships presented by Edmeades et al (1985) suggest responses in annual pasture production to lime application might have been in the order of 9%-10% (200-400 kg DM ha −1 ) during 1976-82 and less subsequently.…”

Effects of superphosphate application rates on pasture production were measured between 1975 and 1988 within 12 grazed farmlets on steep hill country at the Ballantrae Hill Country Research Station in southern Hawke's Bay. The low fertiliser (LF) treatment received 125 kg ha −1 superphosphate pa, and the high fertiliser (HF) an average 625 kg ha −1 pa from 1975 to 1979, then 375 kg ha −1 pa subsequently. No fertiliser was applied to one LF (LFNF) and one HF (HFNF) farmlet after 1980. Soil Olsen phosphorus (P) level declined slightly for the LF treatment as maintenance requirements exceeded P inputs; rose in response to increased fertiliser inputs in the HF treatment but more slowly than anticipated maybe because of the poor fertiliser application history and low starting Olsen P; and declined in the HFNF treatment after cessation of fertiliser inputs. Pasture production was 19% greater in HF than LF in year 1, and on average 39% greater in years 2 to 13. Size of earthworm populations measured up to 30 years after treatments commenced was highly related to level of pasture production, and there was no evidence of deleterious effects of superphosphate application on earthworm populations. Pasture production declined by 3% pa in HFNF after fertiliser application ceased. Variability of annual pasture production was large, year-to-year variation about the mean being 35% for HF and 47% for LF (CV = 8.5% and 12.7%, respectively). This suggests comprehensive farm system redesign will not be required in the near or medium term to cope with the gradual onset of climate change, as farmers already manage large year-to-year variability with existing systems and their careful implementation should suffice. Estimated maximum annual production with non-limiting P supply for lowslope (1-12°), medium-slope (13-25°) and steep (>25°) sites was estimated to be 14.8, 11.5 and 9.4 t DM ha −1 from curves derived using Bayesian statistics. The Olsen P level for 97% maximum pasture production was 18 µg g −1 ; converted to a volumetric basis this equates to about 15 µg mL −1 which is lower than the commonly accepted industry guideline for near maximum pasture production of 20 µg mL −1 .

“…This relationship could partly reflect the influence of riparian shade moderating elevated temperatures that can occur during summer baseflows because of increased air temperatures in urban centres (Wenger et al, 2009). Potential reasons accounting for higher pH where imperviousness was lower are unclear, but may be related to application of lime to peat soils to reduce acidity in upper agricultural catchments that were formerly wetland (Edmeades et al, 1985).…”

Resolving land cover hierarchy relationships in urban settings is important for defining the scale and type of management required to enhance stream health. We investigated associations between macroinvertebrate assemblages in urban streams of Hamilton, New Zealand, and environmental variables measured at multiple spatial scales comprising (i) local-scale physicochemical conditions, (ii) impervious area in multiple stream corridor widths (30, 50 and 100 m) along segments (sections of stream between tributary nodes) and for entire upstream networks, and (iii) total impervious area in stream segment sub-catchments and upstream catchments. Imperviousness was higher for stream segment subcatchments than for entire catchments because of the agricultural headwaters of some urban streams. Imperviousness declined as corridor width declined at both segment and catchment scales reflecting the vegetated cover along most urban stream gullies. Upstream catchment imperviousness was strongly and inversely correlated with dissolved organic carbon concentration, whereas segment and upstream corridor scales were correlated with water temperature and pH. Corridor imperviousness appeared to be a stronger predictor than catchment imperviousness of Ephemeroptera, Plecoptera and Trichoptera taxa richness and the Quantitative Urban Community Index specifically developed to assess impacts of urbanisation. In contrast, imperviousness at all measured scales added only marginal improvement in assemblage-based models over that provided by the local-scale physicochemical variables of reach width, habitat quality, macrophyte cover, pH and dissolved oxygen concentration. These findings infer variable scales of influence affecting macroinvertebrate communities in urban streams and suggest that it may be important to consider local and corridor factors when determining mechanisms of urbanisation impacts and potential management options.
