Martignani technology has been synonymous with sustainability and crop protection for nearly 70 years. Electrostatic charge and low volume spraying allow effective, targeted treatments without waste or drift. This claim is continually confirmed by testimonials from producers around the world and comparative tests conducted by agronomic technicians.
Below is a study conducted in Chile by Agronomic Engineer Pablo Poirot, analyzing the operational and environmental performance of the 2,000-liter Martignani M612 Turbo 2 electrostatic sprayer compared to a conventional sprayer of the same capacity, in Chandler variety walnut plantations (6×5 m planting sixth, 7 m height). Application speed for both machines: 5.1 km/h. Application volume: electrostatic Martignani 500 l/ha, conventional sprayer 2200 l/ha. Average times considered are: 15 minutes outward, 12 minutes return, 7 minutes for tank filling, and 10 minutes for product preparation and refilling.
+120% daily efficiency”
🔍 Methodology
The data collected are based on a typical 8-hour workday, considering:
- Time for emptying, refilling, mixture preparation, and moving
- Area treated daily
- Water, fuel and labor consumption
- Economic and ecological costs and savings on an annual basis

✅ +120% efficiency in the surface treated with Martignani
💧 Water saving
- Martignani consumption: 2000 liters per 4 hectares → 500 l/ha(8000 liters/day)
- Conventional consumption: 2200 l/ha → about 15,994 liters/day
✅ Water savings: 8000 liters/day, equivalent to 480,000 liters/year (considering 60 working days)
✅ Drastically reduced use of drinking or irrigation water
⛽ Fuel consumption and operating costs
- Estimated average savings: 2.3 USD/hour in fuel
- Lower machine and operator time: $26.3/ha total cost savings
- Total daily savings: $252 USD
- Annual savings: US$15,128 (savings generated by one machine)
✅ Higher profitability through lower inputs and greater operational capacity
🌱 Sustainability and environmental benefits
- Martignani electrostatic mist-blowing: electrostatically charged microdroplets distribute evenly over all surfaces of foliage, branches, flowers, and fruit, including hard-to-reach places (such as the inside of flowers and the reverse side of leaves), reducing drift and waste
- Lower environmental impact: less product dispersed into the environment and greater safety for the operator
- Treatment times cut in half = fewer tractor hours in the field, fewer emissions
🔚 Conclusions
The data collected clearly highlight the advantages of using the Martignani electrostatic sprayer in the treatment of Chandler variety walnuts:
- +120% daily efficiency
- Significant savings on water, fuel, time and labor
- Lower environmental impact, higher accuracy
- +15,128 USD saved in a single season
✅ This technology is confirmed as a key tool for modern, more sustainable, efficient and profitable agriculture.
