Plant Nitrogen Fertilizer Utilization Monitor Chlorophyll Analyzer

Introduction. The application of chemical nitrogen (N) fertilizers has greatly increased global crop yields and decreased world hunger over the past five decades (Gong et al., 2011).However, only 30–40 % of applied N is utilized by crops; most is lost in numerous ways, including run-off, leaching, denitrification and volatilization, which together lead to a range of environmental problems ...

Appropriate application of nitrogen (N) can alleviate the salt stress-induced damage on plants. This study explores the changes of nitrogen requirement in feeding annual ryegrass seedlings under mild salt concentrations (50 mM, 100 mM) plus its underlying mitigation mechanism. Results showed that low salt concentration decreased N requirement as observed from the increment in plant height and ...

Nitrogen is an important nutrient that affects rice yield (Jiang et al., 2020). The proper application and testing of nitrogen fertilizer to improve fertilizer utilization can improve rice yield and reduce the negative effects of fertilizer on the environment (Zhou et al., 2020). With the development of science and technology, an increasing ...

2 days ago · Plants were harvested and dried in an oven for 30 min at 105 °C, then at 80 °C to a constant weight and weighed. N concentration was determined using a carbon nitrogen elemental analyzer (Thermo Fisher Scientific DELTA V Advantage). NUE values based on dry biomass were calculated as the proportion of biomass/total N in plants .

22 hours ago · Application of the composite NPK mineral fertilizer was carried out as follows: nitrogen (N) fertilizer was applied in the form of urea with 46% N; phosphorus (P) fertilizer was applied in the form of monoammonium phosphate with 52% P 2 O 5 and 11% N, and potassium (K) fertilizer as a 40% potassium salt (potassium chloride, KCl).
