Beyond Fertiliser: What the Agricultural Drone Can Carry Across Arable Fields
When farmers and land managers first encounter agricultural drone technology, the assumption is often that it's primarily a tool for applying fertiliser. That's understandable; foliar nitrogen is one of the most common drone applications and it's the one that tends to get the most attention. But the range of products the XAG P100 Pro can carry and apply across arable fields is considerably broader than that. For many operations, the most valuable applications are those that have nothing to do with the reason they first looked at drone technology.
What products can an agricultural drone apply beyond fertiliser?
The XAG P100 Pro agricultural drone can apply a wide range of liquid and granular inputs across arable fields. Liquid applications include foliar micronutrients such as magnesium, manganese, zinc, copper and boron; biostimulants including seaweed extracts, amino acid products and humic acids; and plant growth regulators used to manage crop height and lodging risk. Granular applications include seed broadcasting for cover crops, companion crops and environmental mixes, as well as granular fertiliser products where aerial spreading is practical.
What the drone cannot currently apply in the UK is fungicides, herbicides, algicides and other chemical crop protection products. Those must be delivered from the ground, either by conventional equipment or, in settings such as orchards and vineyards, by the XAG agricultural rover.
What are biostimulants and why are they increasingly used in arable farming?
Biostimulants are products that influence plant growth and development through mechanisms other than direct nutrient supply. They include a broad range of materials: seaweed extracts that support root development and stress tolerance, amino acid products that improve nutrient uptake efficiency, humic and fulvic acids that enhance soil biology and microbial products that support plant health from the root zone upward.
In arable farming, biostimulants are increasingly used as part of integrated crop management programmes to maintain yield and quality while reducing reliance on synthetic inputs. They are particularly useful during periods of stress, whether from drought, heat, waterlogging or the physical demands of rapid growth at key crop stages, and their compatibility with drone delivery makes aerial application a natural fit.
How does drone application of plant growth regulators compare to conventional methods?
Plant growth regulators applied via boom sprayer are a well-established part of cereal management in the UK, used to reduce stem length and lodging risk during the spring growth period. The challenge with conventional boom application is timing and access; a wet spring can mean that the window for treatment coincides with ground conditions that make tractor work inadvisable, and by the time the field is accessible the optimal timing may have passed.
The drone sidesteps this problem entirely. It doesn't need the ground to be dry or firm, it doesn't compact the soil and it can be deployed into the crop at the right growth stage regardless of what the weather has done in the preceding days. For farms that have lost growth regulator timing to wet conditions in previous seasons, this is one of the most straightforward practical arguments for drone application.
What arable crops benefit most from drone micronutrient applications?
Cereals are the most obvious candidates, with magnesium and manganese deficiencies both common across lighter, sandier soils and magnesium-deficient upland areas. Oilseed rape has a particular requirement for boron at key growth stages, including flowering, and sulphur applications via the drone can support both yield and quality in this crop. Maize, which is increasingly grown across the Midlands and the South West, responds well to foliar zinc and boron applications at early growth stages when root uptake may be limited by cool soil temperatures.
Potatoes and sugar beet, grown extensively across East Anglia and Lincolnshire, also benefit from foliar micronutrient programmes, particularly where soil conditions or rapid growth create temporary deficiencies that root uptake alone cannot address quickly enough.
Can the drone apply multiple products in a single pass across arable fields?
In some cases, yes, where products are compatible and can be tank-mixed without compromising efficacy or application quality. The practicalities of mixing depend on the specific products involved and should always be confirmed with your agronomist before combining applications. Where products need to be applied separately, the drone's rapid turnaround between tank refills means that sequential applications can often be completed within the same visit, minimising the number of separate operations required across the season.
How does drone application support a reduced-input farming approach?
Precision delivery is one of the central arguments for drone applications from an input-reduction perspective. Product goes where it's needed, at the rate it's needed, rather than being applied uniformly across ground that may not require it. For micronutrients in particular, where the difference between deficiency and sufficiency is relatively narrow, the ability to apply accurately and avoid over-application has both agronomic and environmental benefits.
Combined with scouting data or mapping information that identifies where deficiencies are concentrated, drone application can support a genuinely targeted approach to micronutrient management that reduces total product use while improving outcomes in the areas that need attention most.
How do I find out which drone applications are relevant to my arable operation?
The starting point is your existing crop management programme and your agronomist's advice. Once you know which products you want to apply and at what growth stages, the QuadRotor team can advise on how drone delivery fits into that plan and what a programme of visits across the season would look like.
