Some of the more recent soil survey projects include:
Emirate of Abu DhabiThis government project included an extensive soil survey of approximately 1,000,000 ha (Phase I = 22,000 sampling sites) which was subsequently followed up with an intensive soil testing of approximately 400,000 ha (Phase II = 32.000 sampling sites) in the UAE. As the Senior Soil Surveyor along with GRM International, John Rasic was managing camps, field operations and the team of international soil scientists and technicians, often operating under extremely harsh weather conditions. He organised daily activities, resolved issues as they arose, trained and calibrated the survey crew members, undertook field and office mapping, quality control, identified and described common soil types and developed field definitions for each according to the standards of the USDA.
HASSAD FoodThis premier investor/developer in the agriculture and livestock sector requested to undertake a reconnaissance soil survey of approximately 100,000 ha of land to evaluate soil suitability for intensive cropping using center pivot irrigation relying on water supply from the River Nile. The surveyor combined satellite images, 3D GIS topographical modelling and on-site inspection to select the locations for soil pit examinations using a targeted approach. A similar approach was used to evaluate suitability of approximately 10,000 ha for intensive sheep grazing and cropping sheep production in Georgia.
DAL GroupFor the purpose of this project, a detailed and semi-detailed soil survey were combined to evaluate the suitability of approximately 64,000 ha of land for center pivot cropping irrigation. Thousands of soil pits were excavated to categorise the soils and their distribution patterns in the pre-designing stage. This provided invaluable information which was then used to achieve a spectacular increase in production in the first cropping season, in existing operation regardless of only partial soil treatments.
TADCOIn order to meet a very tight schedule, satellite images, fast screening soil surveying techniques and sparse ground truthing were combined to evaluate several sections of the land totalling approximately 40,000 ha alongside the Senegal River as well as an additional 12,000 ha of the land close to the River Nile and examine some large existing operations in the Kingdom of Saudi Arabia.
AAAID and Al RawabiAn aerial image was combined with a free soil surveying technique and relaxed grid pattern to select soil pit locations for a preliminary suitability assessment of approximately 10,000 ha of the land along the River Nile.
Chanares AltosIn this case a satellite image was combined with free and detailed surveying to evaluate the suitability of different sections of a virgin bushland in Argentina for a range of horticultural crops under drip irrigation.
Al SafiFor this client, satellite images, fast screening methodology and 3D modelling were combined across thousands of hectares of the land to select an area suitable for diverse multi-cropping using the Center Pivot irrigation system.
Al MaraiSimilar to Al Safi, this investor also requested thousands of hectares to be assessed for diverse multi-cropping using Center Pivots. Satellite images, 3D modelling and reconnaissance surveys were combine for the purpose of this project.
Blaxland Vineyards Ltd, AUFor over a decade, JRC has been providing continuous soil services to this client that was only interested in finding and buying the best available viticultural land for his vineyards across Australia (read the testimonial – Ron Collins).
CMV Farms Pty LtdSince the commencement of their irrigation operations in 1980, CMV Farms has been diversifying their enterprise. However, whenever it came to land purchasing, soil treatments and management practices, their philosophy remained the same: second best is unaccepted (read the testimonial – David Crawford).
Great Southern Plantations LtdSince 2006, a wide range of soil surveying techniques have been used and thousands of soil profiles in the states of Western Australia and Victoria were examined to assist the client with land purchasing, irrigation developments and redevelopments (read the testimonial – Professor Robyn Wood).
Timbercorp LtdJRC was appointed to conduct reconnaissance soil surveys for the purpose of purchasing land. These initial investigations were usually followed up with high-intensity soil surveys using ground truthing and soil pit examinations spaced at 75 or 100 metre rectangular grid patterns. Thousands of soil profiles were tested and comprehensive soil reports and maps were prepared to guide various irrigation developments for olives, grapes, almonds, etc.
Webster HorticultureAn initial soil investigation for possible pre-purchasing was followed by detailed soil testing to evaluate the suitability of various parcels of land for drip irrigated walnut production in the Griffith region of NSW, Australia. Both preliminary and detailed soil surveys were based on ground truthing and soil profiling.
Perpetual Forests Pty LtdComplex modelling was used to undertake a detailed analysis of currently available climatic, soil and current land use data of Western Australia to identify an area of 50,000 ha for the potential development of a dryland olive grove for Perpetual Forests Pty Ltd. This was subsequently followed up with a reconnaissance survey and a detailed survey including soil preparation and amelioration recommendations for a trial olive grove.
For some projects, thousands of sampling sites may not be enough to evaluate soil and land recourses. For other projects, however, no or possibly only one testing site could be enough to guide decision making. Logically, every soil survey is different and stands on its own regardless of its size, purpose or cost.
Deep ripping/subsoiling/soil mixing implement ‘Vibrosoiler’ (Australian patent)
The Vibrosoiler is an oscillating-foot ripper or subsoiler with an amplitude ranging from 1 – 3 Hz. It is an ameliorative implement designed to penetrate up to 120 cm depth to fracture some impending layers or modify some soil profiles below the standard cultivation depth.
