“…According to Borges et al (2015), slow-release fertilizer materials may be organic or inorganic; a primary example of an organic slowrelease fertilizers is compost while inorganic examples include urea-based fertilizers (such as urea formaldehyde, isobutylidenediurea, and triazone), magnesium ammonium phosphates and other materials which degrade biologically and are not easily soluble (Tong et al, 2009;Qiwu, 2009). In addition to the efficiency of fertilizers dissolution is very important in the plants' adsorption of fertilizers; the current technology to produce slow-release fertilizers is mainly polymer film coating of a fertilizer grain (Liang and Liu, 2006;Wu and Liu, 2008;Calabria et al, 2012); this coating changes the nutrient solubility characteristics and lengthens and controls nutrient release consequently improving fertilizer use efficiency and minimizing pollution to the environment due to fertilizers losses (AlShamaileh et al, 2018). In contrast, the traditional chemical fertilizers often cause resource waste because the release rate per unit time of nutrients is usually much higher than the adsorption rate by plants, leading to environmental pollution and other problems.…”

“…Slow-release fertilizers are made of materials complex structure and little solubility in water such as the urea-kaolin products. Various synthetic organic products, matrix-based formulations, with the nutrients dispersed in the polymeric or inorganic matrices and polyphosphate-based micronutrient fertilizers so, release their nutrient contents gradually and coincide with the nutrient requirement of plant (AlShamaileh et al, 2018). Thereby, they can minimize the pollution of soil and water associated with fertilizer over dosage and leaching.…”

Background: Slow-release fertilizers (SRF) are quite numerous, and diverse group of materials are involved in the improvement of the effectiveness of fertilization, mitigation of the negative impact of fertilizers on the environment, and the reduction of labor and energy consumption connected with the application of conventional fertilizers. The objective of the experiment was to measure vegetative growth parameters and nutritional status of Nonpareil almond young trees under two types of slow-release compound fertilizers: Matador at 30, 60, and 120 kg/Feddan and Nitrophoska at (25, 50, and 100 kg/Feddan. The experiment was conducted in the Experimental Research Station of National Research Centre at Nubaria, El Behera governorate, Egypt, during successive growing seasons 2018 and 2019. Results: The results indicated that increasing doses of slow-release fertilizer significantly improved vegetative growth of trees. The highest dose of Nitrophoska had significantly higher stem length, diameter, numbers of branches and leaves/trees, leaf area, leaf chlorophyll content, leaf fresh and dry weight while the highest significant of specific leaf dry weight was obtained by applying the highest dose of Matador compared with control trees that received the fast-release fertilizer NPK 19:19:19 at 200 kg/Feddan. Leaf mineral contents of some macro (N, P, K and Mg) and micro elements (Fe, Mn, Zn, and Cu) were significantly increased as a result of application with slowrelease fertilizers. Nitrophoska at 100 kg/Feddan gave the highest values of nitrogen, potassium, magnesium, and iron while Matador at 120 kg/Feddan gave the highest value of manganese. Matador at all doses resulted in a significant increment in phosphorus concentration in leaves in both seasons. Nitrophoska at 100 kg/Feddan and Matador at 120 kg/Feddan recorded the highest values of zinc and copper without significant differences between them. Conclusions: It could be concluded that application with slow-release fertilizers resulted in a positive and significant influence on most investigated vegetative growth measurements and leaf mineral contents of Nonpareil almond trees, since the application with Nitrophoska at 100 kg/Feddan was the most effective treatment for increasing growth measurements and improving leaf nutritional status of Nonpareil almond trees grown under Nubaria condition.

“…Numerous studies have been conducted to learn more about the methods through by which Trichoderma stimulates plant growth and development. Some of these mechanisms can be explained by the overexpression of photosynthesis-related proteins, which results in an increased plant nitrogen use efficiency, and improved plant nutrient absorption [27]. Besides, T1 which is control with topsoil (NPK fertilizer) showed the lowest N content in soil, as due to some N was lost as a result of leaching or runoff.…”

Chili Kulai (Capsicum annuum L) is a typical and popular chili that utilized by Malaysians as a spice in their daily food, emphasize its economic value. The objectives of this study were to evaluate the effect of empty fruit bunch (EFB) compost and Trichoderma biofertilizer on the growth and yield performance of chili production, as well as to determine physicochemical properties of soil and to evaluate N, P, K content of chili plant tissue. The experimental design used was Randomized Completely Block Design (RCBD) with four treatments replicated four (4) times with four plants giving a total of 64 experimental units. The treatments involved were: T1 (Control), T2 (100% EFB compost), T3 (100% Trichoderma biofertilizer) and T4 (50% EFB compost + 50% Trichoderma biofertilizer). The results revealed, there was a significant difference (p<0.05) for growth and yield performance of chili production. As for the nutrient content (%) in both soil and plant, T4 showed the highest NPK content with N (1.98%), P (0.76%) and K (0.69%). In conclusion, this study proved that the use of organic based EFB compost enriched with Trichoderma biofertilizer has increased the yield of chili plant, thus reducing the use of chemical fertilizer.

Novel materials from Feldspar as clay material and KH2PO4 (KHP) are prepared by grinding in a planetary ball mill in a mechanochemical process, one of the most effective ways to synthesize slow-release fertilizers. In two paths, tests were carried out with (3) weight ratio of Feldspar: KH2PO4 contents, at mill The incorporation of KH2PO4 and the liberation of K+ and PO4 3− ions into solution were assessed at rotating speeds ranging from 200 to 700 rpm for two hours, and at milling periods ranging from 1 h, 2 h, and 3 h. Thermal gravimetric analysis (TGA), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and ion chromatography (IC) were employed to analyze the produced materials. The results confirmed that the mechanochemistry process is a sustainable chemistry method to produce amorphous Feldspars containing KH2PO4. After dispersing Feldspar and KH2PO4 in water for 24 h, K+ and PO4 3− ions were measured. Based on these studies, it has been demonstrated that intercalated Feldspar could function as a carrier of K+ ions and release PO3− 4 ions as a slow fertilizer.
