ARA
What does ARA do?
ARA is an ultra-high precision spot sprayer. It uses a set of cameras to capture detailed images of the field, deciphering soil, crops and weeds in real time. Based on the farmer's needs, ARA can selectively target and spray either the crops or the weeds for precise treatments. This allows for tailored herbicide and Crop Protection (fungicides, insecticides, liquid fertilizers, biological products) treatments.
How does ARA work?
ARA uses cameras to take pictures of the field and differentiate between soil, crops and weeds. Depending on the farmer's requirements, the machine targets and sprays the plants with precise dosages, ensuring that only the areas that need treatment are affected. This reduces the use of unnecessary chemicals, optimizes crop care and provides a solution to ergonomic issues.
What speed does ARA operate at?
ARA's ideal operating speed is 7.2 km/h (4.5 miles per hour), ensuring efficient yet precise field treatments.
What are the main benefits of using ARA?
Significant savings on plant protection products:
By targeting only the weeds or specific crops, ARA can reduce plant protection product usage by 50% to over 95%, depending on the target (crop or weeds), crop stage, and weed infestation. We have even seen reductions of up to 98%! (article)
Increased yield potential:
Avoiding touching the crop with the sprays reduces the stress induces to the crop by plant protection products. The crop does not have to detoxify from unnecessary selective products and dedicates all its energy to growth.
Earlier harvest:
The use of selective products affects crop development when applied broadcast. By incorporating ARA to reduce phytotoxicity, farmers may promote inherent growth and achieve an earlier harvest compared to conventional farming. This development allows for quicker market access and improved profitability.
Significant reduction in manual labor:
By applying precise and efficient treatments, ARA reduces the need for manual labor, resulting in major savings. Farmers can apply treatments at specific crop stages that traditional broadcast methods cannot achieve. The use of natural molecules as weedkillers offers new weed management options that take away the costs of manual labor.
Minimal drift:
ARA is designed to minimize drift, with covers on every side of the machine that significantly reduces the influence of wind. This ensures that the plant protection products are precisely applied to the target area, improving accuracy and reducing environmental impact.
Why choose ARA over traditional broadcast spraying methods?
Unlike conventional broadcast spraying, ARA offers precise, plant-by-plant treatment, which drastically reduces chemical usage and minimizes environmental impact. This innovative approach not only benefits the environment but also results in healthier crops, reduced labor costs, and better yields. ARA can also solve agronomic challenges that conventional sprayers cannot achieve so far such as by giving you the flexibility to use alternative chemicals or higher concentrations when traditional inputs aren't working.
SIZE AND DETECTION PARAMETERS
What is the minimum size of weeds that ARA can successfully detect and treat?
ARA can effectively detect and treat weeds with a minimum size of up to 4 x 4 mm (0.16 x 0.16 inches), encompassing both dicotyledons and monocotyledons.
What is the maximum crop height in which ARA can successfully detect and treat weeds?
ARA can detect and treat weeds until the crop reaches a height of 40 cm (15.8 inches). However, it's important to highlight that due to the advanced stages of weed at this size, the results may not meet expectations due to agronomic factors and molecule action spectrum. Therefore, always follow the instructions on the product label used.
What is the minimum size of crops that ARA can successfully detect and treat?
ARA's robust detection of crops begins at the phenological stage of V2 (two true leaves) and beyond. While ARA can be used before this stage, if employed for weed control, it is advisable to exclusively use selective products for the crop before reaching V2.
What is the maximum size of crops that ARA can successfully detect and treat?
ARA can detect and treat crops up to a height of 40 cm (15.8 inches), with no limitation on width or length.
OPERATIONAL SPEED AND PERFORMANCE
What is the maximum speed ARA can operate without affecting its performance?
The recommended maximum tractor driving speed for operations with ARA is 7.2 km/h (4.5 mph).
Does speed variation affect ARA's performance?
The tractor's driving speed does not impact ARA's performance within the range of 0.5 km/h (0.3 mph) to 7.2 km/h (4.5 mph). Performance remains consistent at different speeds.
Disclaimer: The mixture concentration needs to be adapted to the desired speed.
COMPATIBILITY AND INTEGRATION
Can ARA be used in crops that still have no algorithm?
Specific crops algorithms are trained to detect and treat those specific crops. They allow differentiation between crops and other plants, enabling spot applications only on the crop or on every weed, depending on the selected application.
In crops where no algorithms are available yet, other functionalities such as "all plant" or "target size" can be used. "All Plants", can identify and spray all plants (irrespective to the crop or weed), saving product from being wasted on bare soil. "target size" allows you to hit plants of a certain size only, enabling you to work in fields where there's a noticeable difference in size between your crop and the weeds you are targetting.
What are the tractor's horsepower requirements to integrate with ARA?
There is no limitation on the tractor’s horsepower (hp), but the limitation lies in its load capacity (weight to be carried).
The tractor should be capable of carrying 1'100 kg (2'430 lbs) at 1.2 m (3.3 ft) from the tractor’s connector on the back and 1'000 kg (2205 lbs) at 0.8 m (2.6 ft) from the tractor’s connector in the front. Therefore, tractors superior to 90 hp are recommended, with most clients falling in the 120 hp range.
