    Soil Acidity in Oregon

    Declining soil pH is often overlooked because symptoms do not appear, and crop yield does not significantly decline, until a soil pH threshold is reached. Once soil pH drops below the crop threshold, a very small difference in soil pH can result in a substantial yield decrease (Figure 3). This situation differs greatly from a slight nutrient deficiency, which might cause only a 10 or 15 percent yield reduction. When soil pH is a few tenths of a unit lower than a crop’s threshold, yield can decrease 50 percent or more.

    Precision cuts costs, ups yields

    Jim Wilson, of SoilEssentials UK, talks to NZ Farmers about the huge paybacks from precision agriculture, starting with correcting the variability in soil pH.

    “The yield monitor cost more than my header but the results were amazing and very quickly it was clear the variation was caused by low pH. Accurately mapping the variability of my soil’s pH alongside rotational soil sampling enabled precise, variable rate lime applications”.

    Precision Agriculture: Nuffield Scholarship Report – Andrew Williamson

  • 23 Aug

    An exacting approach

    Not so long ago the thought of a machine that maps soil texture and organic matter while carrying out instant soil pH tests was the stuff of arable farmer fantasy.

    But four of Canterbury’s better known arable farmers have invested in just such a piece of equipment, a timely move in this increasingly regulatory environment of nutrient-use efficiency and nutrient management.

    Nuffield scholar Michael Tayler had seen the Veris MSP3 – a machine that measures and maps three soil components in one pass – while on his scholarship travels and had been impressed.

    Back home, a conversation with three other arable farmers – Nick Ward, Hugh Wigley and Colin Hurst – ultimately led to the decision to invest in this piece of precision equipment.

    The four of them imported the machine and set up a company, SMART AG Solutions.

    Certainly the stars aligned when they employed Seaun Lovell to operate both the machine and the business.

    He had recently moved to New Zealand after a 22-year career in the British Army as a tactical ground-to-air communications specialist with the Joint Helicopter Force.

    ICPA Conference Presentation Information

    An important basis for adequate liming is the recording of the soil pH. Several studies indicated a large heterogeneity of soil pH within fields. Recent technological improvements facilitate an on-the-go determination of the soil pH in a much higher sampling density compared to the conventional, time-consuming and costly laboratory method. The Veris Soil pH Sensor allows georeferenced on-the-go mapping of the soil pH. However, the Veris Soil pH Sensor and the widely accepted laboratory method differ in their measuring principles. Hence, it is necessary to adjust the results of the pH sensor to the results of the laboratory method.

    The economic potential of high resolution soil sampling strategies compared to the conventional soil sampling strategies is determined by four effects: the costs of applying the technology, the cost savings resulting from the reduction of over-fertilisation, the improved exploitation of phosphate (which will become plant-available due to small scale pH management) and the expected increase in yield (and thus revenues) resulting from a better lime distribution.

    From precision air strikes to precision ag


    A group of South Canterbury cropping farmers are taking soil sampling to a new level of precision with New Zealand’s first real-time soil sampler. Andrew Swallow reports.

    SEAUN LOVELL spent 22 years in the British Army calling in precision air strikes around the world. Now he’s deploying precision soil sampling techniques on New Zealand farms.

    He’s been in the country a couple of years and was recently employed by four South Canterbury farmers to run start-up company Smart Ag Solutions and its state-of-the-art soil sampler, a Veris MSP3.

    “The Veris will help farmers better understand their soils and where they need to apply more, or less, nutrients and irrigation.

    It’s another tool in the farmer’s armoury,” quips the former Royal Corps of Signals sergeant-major.

    His army role was tactical forward air controller. “That’s calling in fast jets, ground attack helicopters, artillery, etc,” he explains.

    Now he’s operations manager for Smart Ag Solutions and while he didn’t anticipate working in agriculture on leaving the army, his experience operating and maintaining high-tech military communications systems in rugged environments with little or no on-thespot support is ideal, say Smart Ag’s directors. He’s also picked up a feel for farm work on his wife’s family’s farm at Eiffelton, Mid Canterbury.

    Smart soil scanner enhances precision ag

    Advanced soil mapping equipment imported from the United States is giving Kiwi farmers more details about their paddocks than they’ve ever had and promises new efficiencies in nutrient and water use.

    The Veris MSP3 measures soil texture, organic matter and soil pH to provide an exact picture of soil composition so that machinery can then be programmed to apply inputs precisely as required within the mapped paddocks, using variable rate technology.

    The result is more targeted, strategic use of fertiliser, lime and irrigation, less risk of environmental damage, better decision making and ultimately greater farm sustainability.

    Farmers are being urged to regularly monitor the nutrient status and structure of their soils

    “With incorrect pH resulting in drops of crop yield of up to 30 per cent, the wrong pH level can have large financial ramifications for dairy businesses through reduced soil quality, lower uptake of nutrients in slurry, manures and purchased fertilisers, and poorer competition of grass and clover species against weed species.”

    Farmers are also being encouraged to bring along soil samples (quantity of a small spade) to the DairyCo-Eblex-BGS stand to discuss aspects of soil management with the experts. Soil texture and structure will be inspected and tests conducted looking at pH, nitrogen, phosphorus and potassium levels.

    It is also important farmers understand their soil structure. Good soil structure is vital for maintaining productive pastures, however, a recent survey across England and Wales has shown more than 70 per cent of grassland soils are exhibiting signs of soil compaction.

    Precision mapping of soil ‘next step in sustainability’ – Timaru Herald, April 2014

    A new generation of soil mapping technology is giving farmers insights into what lies beneath the surface of their paddocks.

    Four South Canterbury farmers have imported a Veris MSP3 machine from the United States that combines electrical conductivity (EC) mapping of paddocks for soil texture, infra-red measurement of organic matter and constant sampling for soil pH. The machine is towed behind a tractor and takes takes 20-25 ph samples per hectare; and 150-250 soil texture and organic matter samples per ha, feeding the data back to an on-board computer.

    Colin Hurst, who farms at Makikihi, in Waimate District said the end result was a precise picture of the soil’s composition.

    Hurst said data from the Veris would help farmers fine-tune inputs, use nutrients more efficiently, and reduce the risk of environmental damage. “We can see soil characteristics and how they vary in greater detail than ever before, and in a format that will allow us to programme machines to make variable rate applications across paddocks. It will make us all the more environmentally sustainable.”

    Soil mapping was significant for irrigation as well. “We can identify the at-risk soils for n leaching, and identify the soils where you can save irrigation water using precision irrigation.”

    While Hurst and the other three farmers involved – Michael Tayler, Nick Ward and Hugh Wigley – are all cropping farmers, they believe the machine will be equally useful in other farming systems including dairy and livestock farms to improve pasture management. “Grass is a crop just like any other: it needs the right soil pH to maintain nutrient availability to plant and animal, and soil texture and organic matter content are major factors in determining soil water holding capacity, a key consideration in scheduling irrigation.”

    Traditionally, fertiliser, lime and irrigation are applied at one rate across a paddock or even block of paddocks, determined by the average pH or soil water holding capacity. The farmers established Smart Ag Solutions to offer the soil sampling.

    Operations manager Seaun Lovell uses the data collected in the paddock to create maps for clients. “The map shows precisely where your applications can do the most good. With GPS, this allows both the Veris, and the farmer’s machines to identify exactly where they are at any point in time, and apply the right amount of an input, be it fertiliser, lime or water.”

    Components on the Veris include a sapphire window on an optic shoe that sends an infra-red beam 62cm into the soil to measure organic matter. The data is bounced back into the computer in the tractor cab. Discs beside the optic shoe carry electrodes that analyse soil texture up to 91cm down into the root zone.
