· The slow release fertilizer formulations without zeolite (sample 2) have N, P, K nutrient release contents slower than with zeolite (samples 1 and 3). However, the N, P, K nutrient release rates are still high comparing to the commercial slow release fertilizer. Moreover, the coated formulation has the nutrient release contents as well as the ...

The release kinetics of NPK were determined using zeroth, first, second, pseudo-first, pseudo-second order, and Korsmeyer-Peppas kinetics models. The result of the study showed that CTAB modified bentonite has been successfully synthesized for NPK slow-release fertilizer.

 · In this study, we propose a simple biochar-based slow-release fertilizer synthesis technique involving the co-pyrolysis of 10 to 25% (w/w) …

 · SULPHUR90 ® FORT (Sulphur Bentonite) is sulphur rich pastille contains up to 90 % of sulphur added to Bentonite clay which swell the pastille in contact with soil moisture. This will enable an efficient uptake of the sulphur by the growing plants. SULPHUR90 ® FORT (Sulphur Bentonite) are contains high percentage of Sulphur which plays an important role in many …

 · A soil incubation method was used to investigate the solubility characteristics and slow-release mechanism of organic-inorganic compound coated urea at temperature of 10, 20, and 30°C. The membrane microstructure with and without incubation was tested via scanning electron microscopy (SEM). Slow release of nitrogen (N) from different inorganic minerals was …

In this work, a novel slow release fertilizer contained 14.98% nitrogen was prepared via free radical polymerization of acrylic acid, acrylamide, and bentonite in the presence of cross‐linker (N,N′‐methylenebis acrylamide), initiator (potassium persulfate), and nutrient source (urea).The samples were analyzed using a Fourier transform infrared spectrometer, X‐ray diffraction, …

 · Bentonite binds urea to provide a slow release in the rumen, which reduces the risk of ammonia toxicity and promotes a more efficient conversion to protein by the ruminal flora. Bentonite also increases the saliva flow to the rumen. The bicarbonates and phosphates present in the saliva acts as a buffer in the digestive system. Pelletising

 · Currently, developing cost-effective, environmentally friendly, and high-performance biochar-based slow-release fertilizers (BSRFs) is still challenging. In this study, we propose a new strategy for the synthesis of improved BSRFs by copyrolysis of biomass (cotton straw), nutrients (K 3 PO 4 ), and bentonite under microwave irradiation.

 · The release of NH 4 + and PO 4 3-from nutrient-laden biochar composite was 0.30–4.92% and 2.63–5.09%, displaying a good slow-release effect of N and P. Microwave-assisted co-pyrolysis of biomass, nutrient, and bentonite was proposed for the synthesis of slow-release fertilizer .

 · Selection of optimum biochar-based slow-release fertilizer. In order to obtain an optimum blend of biochar, humic acid, bentonite, and adhesive type, the L 9 (3 4) orthogonal experimental design method was applied to test the N release of the biochar-coated fertilizer in water.The N release of the nine biochar-based slow release fertilizer (CF1–CF9) is shown in …
