“…In modern agriculture, a wide range of potash fertilizers is used. FAES is employed to determine the content of potassium oxide K2O in the production of complex fertilizers [112,113] and organic fertilizers [114], using extraction with an ammonium oxalate solution and treatment with a mixture of nitric and perchloric acids, respectively, to decompose the samples.…”

The modern instrumentation for flame atomic emission spectrometry (FAES) is overviewed: the main technical (composition of the fuel gas used, dispersing element, number of analytical channels, reference channel, detecting element, sampling method) and analytical (determined elements, range of determined concentrations, limits and the accuracy of their determination, the duration of a single measurement, the equired amount of the analyzed sample) characteristics of flame photometers for industrial and clinical use as well as spectrophotometers currently made by various manufacturers such as Sherwood Scientific Ltd., BWB Technologies UK Ltd., Labtron Equipment Ltd., Labnics Equipment Ltd. and JENWAY Ltd (UK); A.KRÜSS Optronic (Germany); Cole Parmer Instrument Company and Labfon Equipment Inc. (USA); Inesa Analytical Instrument Co., Ltd (China); OJSC Zagorsk Optical and Mechanical Plant, Unico-SIS LLC and VMK-Optoelectronics LLC (Russia); Manti Lab Solutions, Labtronics, Systonic, Globe Instruments, Electronics India, Lasany (India). The main areas of application of FAES are presented – bioenergy, agriculture (analysis of plants, soil extracts and fertilizers), mineral raw materials (geology), clinical medicine and pharmaceuticals, food industry, environmental control (analysis of drinking, technical and waste water), nuclear energy, metallurgy and chemical industry, as well as some features and problems associated with the preparation of samples for analysis by the FAES method. The review includes references to works on the practical application of FAES, published mainly from 1998 to 2023.

“…The decision of the observation points was carried out by purposive randomized sampling (Rayes 2007). The composite soil sampling and rice leaf samples were conducted for laboratory analysis to obtain levels of nitrogen (Bremner 1996), phosphorus (Bray & Kurtz 1945) and potassium (Zakiyah et al 2018) as macronutrients.…”

Indonesia’s rice production has decreased by 6.83% (on average) in the last five years (2015 – 2019) because of some factors. Salinity (42%) is one of the leading factors that cause decreasing rice production besides climate change (21%), drought (9%), and other factors (28%). The smartphone camera serves as an alternative technology to prevent macronutrient deficiencies due to salinity. This study used aerial photos from android with visible light (R, G, and B), and the image was taken from a height of 5 m. The observation of macronutrient content in plant biomass was carried out using a free grid to adjust rice fields and saline soil. The formula was obtained from regression analysis and paired t-test between the biomass macronutrient and the extracted digital number of aerial photographs that have been stacked. The results showed that digital number (DN) from a smartphone was reliable to predict nitrogen (N), phosphorus (P), and potassium (K) content in rice with formula N = 0.0035 * DN + 0.8192 (R 2 0.84), P = 0.0049 * DN – 0.2042 (R 2 0.70), and K = 0.0478 * DN – 2.6717 (R 2 0.70). There was no difference between the macronutrient estimation results from the formula and the field’s original data.

Gracilaria sp. and Sargassum sp. contain growth hormones such as auxins, gibberellins, and cytokinins. A combination of them is expected to complement each other as raw material for organic fertilizers to improve soil structure and help plant growth. The purpose of this study is to determine the characteristics of organic fertilizer from different seaweed composition. Reduction the size of sample and soaking with 1% phosphoric acid solution to soften the seaweed. Homogenization and heating with the addition of molasses 3% as microbial nutrition and KOH 1% to maximalize mineral content. The fermentation process is carried out for 14 days as microbial exponential phase of Azospirilum sp as nitrogen fixation also phytohormones producer and Trichoderma sp. as an organic material decomposer. The results of ANOVA analysis and Tukey test showed that the treatment of raw material composition using different types of seaweed gives significantly different in C-Organic, nitrogen, potassium, phosphorus, pH, color, and aroma. The composition of Gracilaria sp. and Sargassum sp. give the highest value for C-Organic (1.15%) and Nitrogen (0.67), as well as phosphorus (0.45%), potassium (0.48%), and pH (4.48). Color and aroma are maturity indicators of organic fertilizers. This composition of liquid fertilizer has a pungent aroma and a dark brown color.
