“…In contrast, phosphorus was easily fixed and difficult to be absorbed and utilized by crops [47]. It is reported that coconut bran and biochar contain a high content of basic cations, and the large surface area and negatively charged surface enhance the electrostatic adsorption and retention capacity of Ca 2+ and other cations so that nutrients can be slowly released for plant use [48]. As such, a higher total nitrogen content in the substrate leads to better nitrogen utilization efficiency.…”

To address the problems of inadequate water and fertilizer retention performance of the substrate, which results in the waste of water and fertilizer resources and then contributes to existing agricultural non-point source pollution, this study selected raw materials with different water retention performances for substrate compounding and explored their water retention performance and impact on the growth, yield and quality of strawberries. The experimental setup utilized the strawberry cultivar ‘Hongyan’ as the test subject and incorporated different proportions of vermicompost, coconut bran, biochar and humic acid into the organic fertilizer. A total of 12 treatment groups were formed across three gradients, involving different proportions of vermicompost with 0.05, 0.10 and 0.15 proportions of coconut bran/biochar and 0.05, 0.15 and 0.20 proportions of humic acid. To evaluate the water retention performance, uniform water and fertilizer regulations were applied. The results revealed that the treatment groups T4 (vermicompost:coconut bran = 0.5:0.1) and T5 (vermicompost:biochar = 0.5:0.1) exhibited higher water absorption multiplicity, lower water infiltration rates, and better water retention performances, but there was no significant difference between the two treatment groups. Among them, T4 could effectively improve the nutrient content of the substrate, and the substrate nitrogen-use efficiency (NUE) increased by 5.80% compared with CK2. Also, plant total nitrogen (TN) and total phosphorus (TP) uptake increased by 81.18% and 4.74%, respectively, compared with CK2, which in turn promoted the growth and development of the plant and improved the fruit yield and quality to a certain extent. Meanwhile, T4 had the highest urease and catalase activities, with sucrase activity ranking second only to T1. In contrast, T5 demonstrated greater effectiveness in improving the average fruit weight and maximum fruit weight, registering increases of 22.98% and 36.22% compared to CK2, respectively, but the effect on the total yield was less pronounced. A comprehensive evaluation of strawberry growth found that the T4 treatment was superior. In conclusion, the ratio of vermicompost and coconut bran at 0.5:0.1 improved and promoted the substrate water retention performance and strawberry growth.

“…Of course, before fertilizing with inorganic fertilizers to overcome the high acidity and saturation of Al and the low availability of nutrients and organic matter in Ultisols, organic matter and liming are added (Lin et al, 2018). The application of NPK fertilizer as much as 4 g/pot combined with biochar can increase the availability of macro nutrients N, P, and K as well as sweet corn production in Ultisols (Panjaitan et al, 2022). The application of NPK fertilizer at a dose of 16.7 g/plant on okra can increase the availability of nutrients in Ultisols (Kayode & Adeoye, 2021).…”

Ultisol has main problem of low nutrient availability causing a high percentage of flowers and fruit fall and reducing red chili production. This study aimed to find out effectiveness of biostimulants in reducing percentage of flower and fruit fall, use of inorganic fertilizer doses, and their role in increasing production red pepper in Ultisol. The method used experimental and randomized block design with 9 treatments. The treatment used application of flush biostimulants and without watering into soil with various doses inorganic fertilizers. The fertilizer doses were 100%, 75%, and 50% based on fertilization recommendations. The study results showed that application of biostimulants combined with inorganic fertilizers of various doses had a significant effect on fruit weight/plant and red pepper production, but had an insignificant effect on the percentage of flowers and fruits, as well as number of fruits/plant. Application of biostimulants and various doses of inorganic fertilizers tended to increase fall of flowers, number of fruits/plant, and the percentage of fruit fall. Biostimulants combined with inorganic fertilizers were able to reduce fertilizer use as much as 50%. Production of red pepper with application of biostimulants and 50% of inorganic fertilizers reached 5.36 tons/ha. The results of the economic feasibility analysis of red chili peppers were 1.69 R/C and 0.69 B/C ratio, meaning that the cultivation of red chili with application of biostimulants was profitable and worthy of development. So, application of biostimulants is able to reduce fertilizers by 50% and increase production of red peppers.
