Mechanochemical Preparation of a Novel Slow-Release Fertilizer Based on K2SO4-kaolinite
نویسندگان
چکیده
In this study, a novel slow-release fertilizer (SRF) consisting of kaolinite and K2SO4 was prepared, employing the process mechanochemical milling in planetary ball mill. To obtain optimum time speed, several samples were made at fixed mass ratios kaolinite: (3:1). The rotational speed ranged from 200 to 700 rpm for 120 min. Different times ranging 60 180 min 600 also investigated evaluate incorporation measure liberation K+ SO42? ions into solution. properties studied analyzed by Fourier transformation infrared spectrometry (FTIR), thermal gravimetric analysis (TGA), ion chromatography (IC). is green chemistry procedure that successfully applied incorporate amorphous structure. performance evaluated determining content aqueous solution upon leaching. released amount after 24 h 32 mg L?1 conditions rpm, indicating K2SO4-kaolinite has good properties. SRF cost-effective, environmentally friendly, improves fertilizer’s efficiency many agricultural applications.

Growing Potatoes with Slow-release Nitrogen Fertilizer
Nitrogen management practices have an effect on crop yields but they can also have a negative impact on the environment. Practices such as banding fertilizer and/or split-applying total nitrogen needs per acre offer a more efficient use of nitrogen by significantly reducing nitrate leaching potential. Heavy rains occurring when plants are small and nitrogen demands are low can also increase nit...

In this paper we describe a strategy for sustained release of nitrogen into the soil. Specifically, ureamodified hydroxyapatite nanoparticles were encapsulated under pressure into cavities of the soft wood of Gliricidia sepium. Nitrogen release of the nanofertilizer composition was studied using soil from three elevations in Sri Lanka (pH 4.2, 5.2 and 7) and compared with that of a commercial f...
