A soil survey is a key land management process that involves the identification and classification of different soil types as well as ascertaining their physical and chemical properties within a given area.
Soil mapping is fundamental for assessing the suitability of a particular soil type to horticultural, viticultural, cropping and or livestock farming enterprise.
Helping New Zealand-Aotearoa grow better
Basic soil survey information is available for most parts of New Zealand. However, the most up-to-date information available is a digital soil map (S-map) available from Maanaki Whenua Landcare Research.
As of August 2020, National S-map coverage stood at 36.6%, with 67% of NZ’s high yield land use areas (LUC 1-4: horticulture, cropping, and intensive pasture systems) covered.
S-map coverage throughout NZ varies greatly between and within regions (i.e. Waikato 72%; Bay of Plenty, 59%; and Canterbury, 46%) and at a nominal map scale of 1:50,000. So, for many areas of New Zealand, and at a more refined property-by-property scale where land-use is actively changing, there’s still much to be known and we can assist you with that.
What soil mapping can do for you …
We have the experience and capability to conduct property-specific soil mapping and soil-type characterisation (i.e. texture, rooting depth, drainage, parent material) at any level of detail you require for your property/farm block. For soil-types of preferential interest we can additionally arrange more intensive analyses that include testing the physical (i.e. permeability, bulk density) and chemical (total carbon, total nitrogen, pH, P and P retention) properties of horizons within representative soil profiles.
