NPK Fertilizer With Slow Release Fly Ash

Preparation of Natural multi-nutrient Slow Release Fertilizer (NSRF) aims to reduce the environmental burden from some waste and increase the efficiency of fertilizer in releasing nutrient content. In this study,slow-release fertilizer was prepared from all natural components from waste which aredried chicken manure (N source), struvite (P source), and palm empty fruit bunch ash (K source). The equal weight of the three main nutrient sources was used with the addition of starch powder as the binder by 10%, 15% and 20% of the total nutrient mixture. The mixture of all nutrient with binder was granulated using pan granulator. Dried NSRF granule was tested using sand bed release method to observe the release profile of the contained nutrient. Based on the results of a 30-day leaching study, it was found that increasing concentration of binder will reduce the release of the nutrient from NSRF granules.

Organic And Inorganic Fertilizers

The aim of this experiment was to compare the influence of organic and inorganic fertilizers on selected indicators of turf growth-production process under non–irrigated conditions. The experiment was carried out in warm and dry conditions in the area of Nitra (Slovak Republic). In the experiment were included 5 treatments: 1.Without fertilization, 2. Turf NPK fertilizer 15–3–8 (+3 MgO +0.8 Fe +18 S), 3. Slow release NPK fertilizer 14–5–14 (+4 CaO +4 MgO +7 S), 4. Organic NPK fertilizer 5-1-1 and 5. Organic NPK fertilizer 3-2-1. Determination of the average height of turf, total height of turf and the annual average daily gain of height showed that best treatment was application of slow release fertilizer. Turf fertilized by Organic NPK fertilizer 5-1-1 reached the highest values of the average height of turf, total height of turf and the annual average daily gain of height, the same as treatment without fertilization. These finding were statistically significant. Treatment without fertilization reached the lowest values in evaluated growth-production parameters.

Plant Fertility

Urea (CO (NH)2) is one of the compositions in making fertilizer. Fertilizer is crucial, especially for plant growth (affecting plant fertility). If a plant had urea fertilizer on the soil, nitrogen in the fertilizer releases quickly, and it will cause environmental pollution. Therefore, many studies want to develop urea fertilizer to be more efficient to use. The purpose of this review is to find the most appropriate method for the efficient use of urea as seen from the material used, the technique used, and the results obtained. This review shows that the most appropriate method is the slow release method with NaOH and fly ash ingredients. Because this method can increase the effective utilization of urea, reduce environmental pollution, and be relatively more straightforward, the raw material is more affordable and spread widely in the market.

Npk Fertilizer

Biochar is a solid material produced by thermochemical conversion of biomass under oxygen-limited conditions. It has a wide surface and contains many pores so that it can be used as a material for making fertilizer. Biochar based slow release NPK fertilizer was formulated and developed to reduce nutrient leaching and greenhouse gas emissions. In this research, biochar which was a by-product of biomass gasification using oil palm empty fruit bunches was processed to make slow release biochar NPK fertilizer. Sources of nitrogen (N) were derived from urea, phosphate (P) from diamonium phosphate (DAP) and potassium (K) derived from potassium chloride (KCl). Zeolite was added as a matrix to improve fertilizer characteristics. All materials were formulated to make slow release biochar NPK fertilizer used for red onion (Allium sepa) plant applications. Several micronutrients were also added including Mg (MgSO4 fertilizer) and S (ZA fertilizer) to support plant growth. The characterization of fertilizer products was carried out by using SEM, BET etc. to determine physical properties including surface area, pore volume, morphology and composition. Furthermore, biochar NPK fertilizer was applied to the red onion plant which was a high-value crop in Indonesia. The application of NPK biochar fertilizer on red onion plant showed its superiority compared to commercial NPK fertilizers. In addition, the use of Magnesium and sulfur micronutrients could support the growth of red onion bulbs so that they produced more and bigger bulbs.Keywords: biomass, gasification, oil palm empty fruit bunches, biochar, slow release fertilizer*The paper has been selected from a collaboration with IPST and 7th ICFCHT 2019 for a conference entitled "Innovation in Polymer Science and Technology (IPST) 2019 in Conjunction with 7th International Conference on Fuel Cell and Hydrogen Technology (ICFCHT 2019) on October 16th - 19th at The Stones Hotel Legian, Bali, Indonesia"
