EFFECT OF CONTROLLED-RELEASE FERTILIZER ON MAIZE YIELD AND NUTRIENT UPTAKE UNDER A FERTILIZER ONE-TIME POINT-APPLIED SYSTEM

چکیده
Currently, maize production in China suffers from many problems, such as excessive fertilizer application, inefficient use, and insufficient agricultural labour. The effect of one-time mechanical point-applied fertilization controlled-release compound the root-zone on yield nutrient uptake was investigated to explore efficient patterns for decrease increase maize. selected a granular (24-6-10 N-P2O5-K2O) with six treatments application program: 1) no (CK); 2) banding (BDP) 5 cm off seeds between rows 10 deep; 3) (RZF) seed row 4) (90% RZF) 10% reduction 5) (80% 20% 6) (70% 30% deep. results showed that RZF increased by 5.84% over BDP, difference significant, indicating mechanized can replace manual operations achieve crop yield. agronomic utilization rate 12.35% bias productivity 5.31% were higher than differences root zone significantly improved reduced loss.

Thermal post-treatment alters nutrient release from a controlled-release fertilizer coated with a waterborne polymer
Controlled-release fertilizers (CRF) use a controlled-release technology to enhance the nutrient use efficiency of crops. Many factors affect the release of nutrients from the waterborne polymer-coated CRF, but the effects of thermal post-treatments remain unclear. In this study, a waterborne polyacrylate-coated CRF was post-treated at different temperatures (30 °C, 60 °C, and 80 °C) and durati...
