Rapid synthesis of a corncob-based semi-interpenetrating polymer network slow-release nitrogen fertilizer by microwave irradiation to control water and nutrient losses
This paper presents the rapid synthesis of a corncob-based semi-interpenetrating polymer network (semi-IPN) slow-release nitrogen fertilizer (SRFs) with bentonite additives via microwave irradiation at 320 W for 4.5 min. The SRFs were based on urea incorporated in a polymer matrix composed of cornco...
