Chertsey Establishment Trial
This experiment has been added by the GLTEN Curators using existing published sources.
- Objective
- To provide evidence that a progressive shift to a reduction in cultivation intensity would not penalize crop production under an intensive annual cropping rotation.
- Description
- The Chertsey Establishment Trial is also know as the Chertsey Long-term Cultivation Trial

- History
- The site was previously farmed under a mixed cropping system using intensive cultivation for more than 20 years.
- Management
- Crop protection and nutrition inputs are the same across all treatments. Inputs are usually non-limiting.
- Soil type
- umbrisol
- Soil description
- Classified as a Chertsey Silt Loam under the New Zealand Soil Classification. 40-60cm top soil over gravels.
- Climate properties
Variable Time period Value (range) Units precipitation 660 millimeter
Design period: Original establishment treatments (2003—2017)
- Design Type
- Split-plot
- Design description
- Irrigation treatments make up the four main plots, with each plot split into 6 sub plots testing the 6 different establishment treatments.

deficit irrigation process
Irrigated treatments aim to remove soil moisture deficits and usually receive 250-300 mm of applied irrigation.rainfed process
- tillage process Tests 6 different establishment methods on sub-plots
minimum tillage
Cultivation using 2 passes with a disc type cultivator operating in the surface layer.minimum tillage
Cultivation using 2 passes with a disc type cultivator with rippers to remedy compaction.no-till
2 sub-plots where the crop was sown with no prior cultivation using a disc drill.no-till
2 sub-plots where the crop was sown with no prior cultivation using a cross-slot drill.conventional tillage
Inversion plough followed by one pass with a disc type cultivator.conventional tillage
Inversion plough followed by two passes with a disc type cultivator.

Design period: Revised establishment treatments (2017—)
- Design Type
- Split-plot
- Design description
- From September 2017, the size original cultivation treatments were reduced to three by combining the inversion, minimum and no-tillage treatments. This increased the number of replicates from 2 to 4 for each treatment
