Synthesis of slow-release fertilizer with coconut shell biochar and activated natural zeolite for red onion (Allium ascalonium)

<p>Using fertilizers is one of the efforts to increase crop productivity, but conventional fertilizers tend to be easily leached so it becomes ineffective. Slow-release fertilizer (SRF) is a modified fertilizer that releases nutrients slowly or gradually so that the use of fertilizer becomes more effective. SRF can be synthesized by mixing fertilizers with zeolite as a slow-release agent. Because natural zeolite contains many impurities that cover the pores of the zeolite, it is necessary to carry out an activation process to increase the pore capacity of the zeolite so that the process of absorption of nutrients in the SRF becomes more leverage. This study aimed to synthesize NPKSMg slow-release fertilizer with coconut shell biochar and activated natural zeolite for red onion plants (<em>Allium ascalonium</em>). Coconut shell biochar was used as a source of potassium. The activation process of natural zeolite was carried out by the desilication method using a basic solution of NaOH as an activator. Based on the results of research using activated natural zeolite on SRF, the surface structure of SRF became more porous, with a porosity percentage of 69.31%. In addition, the use of activated natural zeolites increased the absorption of nutrients in fertilizers. The use of biochar in SRF increased the percentage of porosity by 66.32%. The use of coconut shell biochar as a matrix and activated natural zeolite as a slow-release agent in SRF NPK S Mg for red onion plants has succeeded in increasing red onion yields.</p>

Effect of acid modified tea-waste biochar on crop productivity of red onion (Allium cepa L.)

Biochar has widely been utilized as an agricultural soil amendment owing to its enhanced surface properties and cost-effectiveness. In the present work, the influence of tea waste biochar (TWBC) upon acid modification on Allium cepa L. (red onion) growth has been studied. Its effect as a soil amendment has also been studied by assessing the nutrient retention, microbial population growth and immobilization of potentially toxic metal ions. A greenhouse experiment was carried out by applying different biochar (BC) ratios (2% and 5% w/w) to soil as the growth media for onion plants. A 2.4 times (2.4 × ) reduction of phosphate from leaching was observed upon BC application at a ratio of 2% than that of 5%. Moreover, red onion plants that grew in the BC-fertilizer amended soil at a 2% ratio showed higher growth compared to that of 5%. A ∼1.3 × and ∼1.2 × increment of total dry weight was observed upon amendment of soil fertilizer system with nitric and sulfuric acid-modified TWBC, respectively. An analysis of the potentially toxic metal ion uptake by the respective plant parts showed that lead uptake by the roots of red onion was ∼8.3 × less in BC amended soil compared to that in contaminated soil. Thus, acid-modified TWBC can be considered a potential soil amendment for an enhanced red onion growth. Employing TWBC as a soil amendment in tropical countries, where tea-waste is in abundance, will boost sustainable agriculture.

Oil palm empty fruit bunch ash as a potassium source in the synthesis of NPK fertilizer
