“…bio silicic acid so-called BioSilAc, which combines the microbial and nanotechnological approaches . The formula has been shown improving performances of oil palm, sugarcane, and soybean against drought stress (Goenadi et al, 2019;Amanah et al, 2019;Santi et al, 2019;Santi et al, 2018). However, the impact of using BioSilAc to rice grown on soils in tidal swamp area has not been reported yet.…”

The soils in tidal swamp land as new development area for rice in Indonesia have a considerably low available silica (Si) because very acid condition and no Si fertilization. Therefore, increasing the productivity of rice as Si accumulator plant, in tidal swamp land requires silica fertilizer. This research presented the effect of applications of silicon in the form of orthosilicic acid (H4SiO4) enriched with selected Sisolubilizing fungi, formulated as 4-gram tableted Si fertilizer (BioSilAc) on tidal swamp land soil to improve yield and reduce chemical fertilizer dosage for rice. Field experiment was conducted in Ketapang subdistrict, South Lampung by using a Randomized Block Design (RBD) with six treatments and four replicates. The treatments consisted of (ha-1 season-1): 100% NPK recommended dosage (P1); 100% NPK + 80 BioSilAc tablets (P2); 75% NPK + 80 BioSilAc tablets (P3); 75% NPK + 100 BioSilAc tablets (P4); 50% NPK + 120 BioSilAc tablets (P5); and control (P6). The results showed that P2 treatment increased the highest rice yield in dried harvested grain by 7.6% or equivalent to 500 kg ha-1 compared to P1 treatment. The highest fertilization efficiency can be achieved in P4 treatment which means the NPK recommended dosage can be reduced 25% by adding 100 BioSilAc tablets ha-1 season-1 indicated by insignificantly different productivity compared to that of P1. The Revenue/Cost (R/C) values showed that P2 treatment was economically feasible fertilization practices.

Optimization of degraded semi-arid upland needs to be done by improving soil fertility and quality, as well as increasing plant resistance to drought. The purpose of this research is to evaluate the effect of balanced fertilization and soil ameliorant on soil quality and crop productivity. The study was conducted on degraded semiarid upland in Gunung Kidul Regency, Yogyakarta, Indonesia at the beginning of the dry season in 2018. Randomized block design with five treatments and four replications was applied. The treatments consisted of TP: control (farmer management), T1: Balanced fertilization recommendation, T2: T1+Biochar SP-50, T3: T1+Bio-silica, T4: T1+Biochar SP-50+Bio-silica, and T5: T1+Vulkanorf K-424. Soil ameliorant treatment had a positive effect on water aggregate stability. Treatment of Biochar SP-50 in combination with Bio-silica had a positive effect on soil bulk density, aeration pore, and water availability pore. Balanced fertilization accompanied by Biochar SP-50 (without and with bio-silica) gave a positive effect on the content of soil organic C and K-potential. Plant growth of balanced fertilization+Biochar SP-50 was significantly higher than other treatments, while maize production among treatments did not show a significant difference. Therefore, it requires long-term and continuous treatment to improve soil quality and crop productivity in degraded land.
