NOMINEE JACOB VAN DEN BORNE ▶▶▶


After comparing several crop sensors, Jacob concluded that the Fritz- meier Isaria is the best performing sensor for his circumstances.


Farming, fertilisation and crop protection ac- cess research funding for the amount of the in- vestment by using so-called miles.” This gave the farmers the opportunity to test all the available crop sensors at that time: Fritzmeier Isaria, Crop Scan, Yara N-Sensor, Crop Circle


Yet another piece of technology that was bought after comparing sev- eral alternatives: the Dualem-21S soil sensor.


and GreenSeeker. “In fact, buying the Fritzmei- er sensors gave us miles to invest in the com- petitive sensors. We then tested all of them for one year in our potato crops and concluded that the Fritzmeier Isaria is the best performing crop sensor for our circumstances.”


8 questions for the Top 10 nominee


1) Who are you? I am Jacob van den Borne 2) When did you first start with precision farming? In 2006 with gps section control on our sprayer 3) What is your main motivation to use the technology? Using it as a management tool for the 300 rented fields and to uti- lise the soil’s yield potential 4) What are the most interesting things you’ve learned? Knowing what we are growing, and realising what’s going on with crops 5) What are your main tips for precision technology starters? Start with yield monitoring to map the yield potential of your fields 6) What is your main tip for experienced users? Keep it simple and understandable. Don’t overdo it technology wise 7) What went wrong? I initially bought the wrong crop sensors for use in potatoes and I bought the wrong drone a couple of times 8) What will be your next step(s)? Simplification and knowledge transfer to employees, farmers and the industry


12 ▶ FUTURE FARMING | 27 August 2019


Turning (to) the soil Two main reasons steered Jacob and his broth- er towards the use of crop sensors. Firstly, over 400 hectares (300 fields) from the total acre- age of 600 hectares is rented/leased. And al- though the growers intend to use each rent field once every four years fitting their crop ro- tation scheme, they ‘do not know anything about the fields and their history’. The other reason is that the rented fields are mostly fer- tilised by their owners , which is beyond Ja- cob’s control. The crop sensors enable him to apply fertiliser VRA to compensate for differ- ences in manure compositions but not to the extend Jacob liked. For that reason, he turned to soil scanners in 2011 (also see the overview in Future Farming magazine NO.2 2019). “Thanks to the PPL-program, we could start testing the Geonics EM-38 soil scanner. As well as the Miramap soil moisture scanner, the Veris MSP3 and the Dualem-21S scanners.” Nowadays, Jacob prefers to use the Du- alem-21S as this sensor, even though it is very comparable to the EM38-MK2. It does not re- quire any calibration and it has more coils for deeper and more accurate conductivity (EC) measurements. In addition, he deploys a gam- ma sensor as research concluded that available potassium (K) in the soil can be accurately mapped using radioactivity and because potassium is a vital element for potatoes.


Founding an own airport Jacob prides himself on being a forerunner and pioneer in working with the newest technolo- gy and concepts. This includes owning and fly- ing drones (UAV’s). This was initially made
