New precision drill controller offers unrivalled row crop seeding accuracy

  • LH Agro has announced the launch of a universal row crop planting controller which enables growers to establish sugar beet and maize more accurately and with reduced seed wastage

The new Topcon Apollo CM-20 row crop planting controller is fully ISOBUS compliant, with its plug-and-play design enabling it to be retrofitted to most existing precision drills and to be used with any ISOBUS compatible implement control console.

The new controller can monitor the accuracy of row crop seeding operations in real-time and relay this information back to the drill’s operator so that any anomalies can be dealt with immediately.

“Accurate planting is the essential first stage of any cropping cycle, with the precise application of large seeds vital to the successful establishment and yield producing ability of row crops such as sugar beet and maize,” explains Richard Reed, Managing Director of LH Agro, Topcon’s preferred distributor in the UK.

“The Apollo CM-20 row crop planting controller enables growers to carry out this vital operation with improved accuracy thanks to its ability to monitor and control the placement of individual seeds as well as controlling the variable rate application of up to three additional granular products such as a starter fertiliser or micro and macro-nutrients.”

The Apollo CM-20 can control the function of up to 24 electrically driven seeding units and to make on-the-fly adjustments to avoid seed wastage as a result of overlaps or misses at headlands or in the corners of awkwardly shaped fields.

“In addition to auto-section and variable rate control, the new controller’s biggest single advantage is its ability to monitor singulation and spacing accuracy and to ensure that each seed is dropped in exactly the correct position,” Mr Reed continues.

“This even includes at bends in the field where the CM-20’s turn compensation feature reduces the seeding rate towards the inside of the curve and increases it at the outer radius where the drill’s seeding coulters will effectively be travelling further and faster. This ensures all seeds are planted at equal distances irrespective of irregularities in field shape and helps crops to achieve their full potential by maximising crop uniformity for optimum light inception and to minimise competition between neighbouring plants.”

The new controller is also compatible with the Topcon Agriculture Platform (TAP) which allows seeding data and prescription mapping information to be relayed from the implement to the farm office and vice versa.
