The Impact of Agriculture on the Taranaki soils The Taranaki region The Taranaki region covers 723,610 ha (3% of New Zealand). •414,000 ha (57%) used for high intensity pastoral farming • 2300 dairy farms (17% of all dairy farms in New Zealand) •1150 sheep and beef farms • 16 piggeries • 41 poultry farms • 290,000 ha in indigenous forest and shrubland • 17,600 ha of exotic forest plantings Taranaki Landuse • Pastoral farming 57% • Native forest 30% • Scrub 9.5% • Planted forest 1.5% Agricultural impacts on soil • Taranaki has a wide range of soil types from fertile, well drained volcanic ring plain soils to relatively infertile and erodible sedimentary based soils of the inland Key issues regarding Taranaki soils • 92% of the region is sustainably managed with no significant soil erosion problem • 97% of Taranaki soils have low risk of long term damage through soil compaction(via pugging by cattle in wet weather. • There have been significant landuse changes over the past decade • As stocking rates increase, extra pressures are placed on the soil. Intensification of Dairy farming in Taranaki Soil Erosion • The potential for erosion in the inland hill country is naturally high and can be accelerated by land clearance/pasture establishment • Many ‘at risk’ areas are being retired or planted in plantation forestry Landuse changes in the Taranaki hill country Managing Erosion prone hill country
