Experts at the the University of the Philippines Los Baños (UPLB) are currently testing nanofertilizers in order to increase the yield of agricultural crops, including sugarcane, rice, corn and vegetables.
This initiative came because inorganic fertilizer, being an important input that is required to achieve challenging yield targets in sugarcane farms, it is costly and known to deteriorate the environment when not managed properly.
Not all nutrients from inorganic fertilizers could be assimilated by the crop. Some are lost due to runoff and leaching.
With the application of nanotechnology in agriculture, these losses can be reduced. Hence, nanofertilizers are emerging as a promising alternative.
FertiGroe N, P and K are the new slow-release nanofertilizers. These are nano-sized (1 nanometer to 100 nm) particle technology that increases surface area for nutrient adsorption.
It was found that the products offer better economic yield and safer for the environment through their strong potential of slowing down or controlling nutrient release to increase nutrient use efficiency.
The Agricultural Systems Institute and La Granja Research and Training Station (LGRTS) of UPLB are currently testing the formulated FertiGroe N, P, and K nanofertilizers for sugarcane through the project, “Development of Application Protocol and Field Verification of FertiGroe N, P, and K Nanofertilizers in Sugarcane.”
The project is one of the seven components of the program “Optimization of the Production and Use of FertiGroe N, P, and K Nanofertilizers in Selected Agricultural Crops,” funded by the Department of Science and Technology and monitored by the Philippine Council for Agriculture, Aquatic and Natural Resources Research and Development (DOST-PCAARRD).
The program aims to optimize the production process and develop application protocols of FertiGroe N, P, and K nanofertilizers to increase yield of rice, corn, vegetables, sugarcane, coffee, cacao and banana.
Initial results of the field evaluation trial show that the FertiGroe nanofertilizers-treated sugarcane obtained as much as 218.76 50kg-per-hectare (Lkg/ha), which is higher than the average yield of 129.62 Lkg/ha in La Carlota Mill District, Negros Occidental.
Use of the nanofertilizers increased nutrient uptake, minimized nutrient losses, reduced fertilizer inputs by 50 percent and reduced production costs.
Efficacy trials are still ongoing and are expected to be completed soon.
The trademark of FertiGroe has been registered at the Intellectual Property Office of the Philippines (IPOPhil).
The products are for patent application at the IPOPhil and for registration at the Fertilizer and Pesticide Authority.
These initial progress and accomplishment were discussed between the DOST-PCAARRD monitoring and evaluation team led by Dr. Juanito T. Batalon, Agricultural Resources Management Research Division-PCAARRD director, and the UPLB-LGRTS project team led by Dr. Emmanuel G. Samson, during a field monitoring and evaluation visit done before the Covid-19 pandemic occurred.
