“…Additionally, chitosan activates soil microorganisms as it serves as a source of essential nutrients for their growth. All these factors contribute to the overall growth, yield, and dry weight of the plant compared to NPK fertilizer, which aligns with previous findings Malerba and Cerana (2016) ‫و‬ Behboudi et al,(2018) and Vince et al,(2019) .…”

A field experiment was conducted at the College of Agriculture, University of Basrah's research station in Karama Ali during the 2022 agricultural season. The study aimed to investigate the impact of three types of fertilizers (commercial NPK as a control and two types of prepared NPK-Chitosan organic fertilizers) at four addition levels (0, 1, 1.5, and 2 ton.h-1) and two levels of organic matter (0% and 2.5%) on the nutrient availability in sandy loam soil. The experimental soil was prepared by plowing, levelling, and dividing it into 6 m² plots. Two levels of composted cattle manure (0 and 2.5 tons.h-1) were mixed with the soil, and fertilizers were prepared at four levels for each fertilizer. Seeds of yellow corn (Zea mays L.) variety "Sagunto" from Fito, a Spanish company registered with the Iraqi Ministry of Agriculture, were sown with 5 seeds per hill and a spacing of 40 cm between hills. Crop management practices, including disease and pest control, irrigation, and weeding, were carried out until the end of the growing season. At the end of the growing season, soil samples were collected to determine the available nitrogen and potassium content. The results indicated that the addition of slow-release NPK-Chitosan fertilizers and organic matter significantly increased the availability of nutrients in the sandy loam soil. NPK-Chitosan fertilizer with a 1:3 wrapping ratio and NPK-Chitosan with a 1:3 mixing ratio showed superior performance compared to the control fertilizer (NPK) in increasing the concentration of essential plant elements. This enhancement in nutrient availability positively influenced the overall yield of yellow corn plants. In conclusion, I took samples, and the results showed that adding slow-release fertilizers NPK-Chitosan and organic fertilizers led to a significant increase in dry weight and total grain yield for the yellow corn crop. The NPK-Chitosan fertilizer, either in a 1:3 coating ratio or a 1:3 mixing ratio, outperformed the comparative NPK fertilizer in increasing the dry weight and grain yield for the yellow corn crop, reflected in the overall yield of the yellow corn plants. The results indicated a significant effect of fertilizer type on increasing the yellow corn plants' dry weight and grain yield for the added fertilizer type. The NPK-Chitosan fertilizer in a 1:3 coating ratio achieved the highest values of dry weight and grain yield for the yellow corn plants, reaching 41.79, 6.15, and 47.07 kg.h-1, respectively, followed by the treatment of NPK-Chitosan fertilizer with a 1:3 mixing ratio and a fertilizer level of 2 tons.ha-1, which yielded The results showed a significant effect of fertilizer level on increasing the dry weight and grain yield of the yellow corn plants. The dry weight and grain yield increased with higher levels of added fertilizer. Level 2 achieved the highest dry weight values for the vegetative part and grain yield for the yellow corn plants, reaching 2 tons h-1.35.72, 3.63, and 40.38 kg.h-1, significantly different from level 1 and 1.5 tons .h-1. Level 2 also outperformed level 0 tons h-1 (the control treatment). Similarly, the organic matter showed a significant effect. The results indicated a significant interaction between the type and level of fertilizer and the level of added organic matter to the soil on the dry weight and grain yield of the yellow corn plants. The NPK-Chitosan fertilizer with a 1:3 coating ratio added at 2 tons.h-1 outperformed the other treatments, yielding the highest dry weight and grain yield.

“…In this context, Merino et al (2019) [19] used corn starch films to incorporate sodium to crops. Mesias et al (2019) [20] and Kartini et al [21] incorporated NPK (nitrogen, phosphorus and potassium) fertilizers in chitosan/alginate capsules and carboxymethyl cellulose bioplastics, respectively. However, the raw materials and techniques used to manufacture these systems have great scalability problems and, therefore, they cannot compete with conventional fertilization (their price ranges from 1.50 to 22.00 €/kg compared to 0.75-3.00 €/kg of conventional fertilizers).…”

Controlled Release of Zinc from Soy Protein-Based Matrices to Plants

et al. 2021

Controlled release systems are increasing their presence on the market. However, their use is not generating a great impact on horticultural production, mainly due to their price, which makes crop production more expensive. This work proposes a cheaper alternative for the manufacture of these devices. Thus, an agri-food byproduct (soy protein isolate) and a thermomechanical processing were used to create devices (matrices) that can compete in price with the use of conventional fertilizers (0.50–2.00 €/kg). First, different processing methods were evaluated to obtain the matrix with the most optimal mechanical, functional (zinc and water retention/release, biodegradability) and morphological (zinc distribution) properties for the supply of zinc (micronutrient). This was achieved by incorporating an ethanol immersion step into the processing to remove the plasticizer before its use in horticulture. Finally, the efficiency of these matrices was verified in crops (lettuce and peppers), improving up to 60% the assimilation of zinc by plants that conventional fertilization achieves. In addition, these matrices allow a 33% reduction in the water used during cultivation. This work has opened a new possibility of creating more efficient devices for the incorporation of fertilizers into crops, also having an affordable price for industrial use.

Fiber-reinforced polymer composites have received increased attention due to their environmental friendliness and sustainability, aside from at par-if not betterproperty enhancement achieved through fiber reinforcement over mineral-based fillers. The purpose of this article is to provide a comprehensive review on the various methods of fiber-based polymer composites preparation as well as their applications, particularly focusing on abaca-reinforced hybrid materials. Among the natural fibers available in the market, abaca fiber has been a major contender in the development of natural fiber composites. It has a great potential to be a renewable fiber source for industrial and technological applications owing to its inherent high mechanical strength, durability, flexibility and long fiber length. Impacts of different treatment strategies of abaca-based composites preparation resulting in property enhancements over bare polymer counterparts and that of synthetic fibers are discussed. Being eco-friendly and naturally sustainable, abaca fiber-reinforced composites can also exhibit better strength without substantial weight gaincharacteristics that have been exploited in various commercial and technological uses. How these enhanced properties of the resulting composites had led in a wide range of applications such as in the automobile and construction industries and other fields had been included as well.
