ICL Specialty Fertilizers files for patent on apparatus for rice fertigation
New in-house invention eliminates intense labor associated with fertilizer application in rice fields
ICL Specialty Fertilizers under the name of Everris International B.V. filed a patent application at the United States Patent and Trademark Office on 30 August 2018. The patent relates to the apparatus for surface irrigation that has been designed more specifically for rice fertigation. The new invention popped up from in-house development based on ICL Specialty Fertilizers’ expertise in fertigation, consisting of drip emitters (on-line drippers or integral drip lines), minimally elevated reservoir tank and gravitational energy.
‘It is very tough to have to wade through muddy rice fields under the blazing sun, while shouldering a 30 kg knapsack applicator for top-dressing,’ says Masahide Tabata, Area Sales Manager for ICL Specialty Fertilizers in Japan and Korea, and inventor of the apparatus. ‘We wanted to develop a device that could eliminate the high-intensity labor that comes with the application of fertilizers in rice fields. The result is this apparatus: it enables the solution of water-soluble fertilizers (nitrogen, phosphate and potassium) to flow precisely from a water inlet point outside of the field, and surface irrigation supplies the solution continuously to the rice field.’
The new apparatus is economical, trouble-free, user-friendly and accurate to operate. On top of the labor-saving aspect, field trials have revealed that improved nutrient management can be achieved with the apparatus, thanks to its even distribution of nutrients.
ICL Specialty Fertilizers is to attend the 5th International Rice Congress held at Marina Bay Sands, Singapore from 15 to 17 October 2018 to present the new invention in the form of a poster. If you plan to visit the congress, please make sure to stop by the stand. Tabata is looking forward to welcoming you there.
