Abstract

Sistem tanam raised bed beralaskan limbah organik diduga berdampak terhadap kecukupan air, nutrisi, dan gas-gas tanah. Tujuan penelitian untuk mengkaji pengaruh variasi ketinggian raised bed terhadap perubahan sifat fisik dan kimia tanah terpilih. Penelitian dilaksanakan pada bulan Juni hingga Agustus 2025 di Jemur Wonosari, Surabaya. Rancangan Acak Kelompok digunakan untuk mengevaluasi  perlakuan  ketinggian raised bed : 20 cm (P1), 25 cm (P2), dan 30 cm (P3), masing-masing diulang tiga kali. Sampel tanah diambil pada kedalaman 0-20 cm pada setiap raised bed untuk dianalisis nilai pH tanah, EC, dan C-organik tanah. Hasil penelitian menunjukkan bahwa ketinggian raised bed mempengaruhi nilai ciri tanah tersebut. Nilai pH tanah berada pada kisaran 7,08–7,63, nilai EC tanah antara 0,594 dS/m dan 0,402 dS/m, dan kandungan C organik antara 1,09% dan 0,6%. Kandungan C organik berbanding terbalik dengan EC tanah. Bedengan yang ditinggikan optimal pada ketinggian 25 cm karena dapat menjaga kelembapan, aerasi, dan mendukung dekomposisi bahan organik yang baik.

Abstract

Soil degradation caused by industrial waste in Sidoarjo Regency has led to a decline in agricultural productivity, necessitating soil rehabilitation efforts. This study aimed to evaluate the effectiveness of silica humate as a soil amendment on paddy fields contaminated by industrial waste. The experiments were arranged according to the Factorial Complete Randomized Design, where the first factor: 3 kinds of industrial waste namely the pharmaceutical, livestock feed, and paper industry. Second factor; 5 doses of silica humat (0, 10, 20, 30, and 40 kg/ha). The parameters included soil pH, cation exchange capacity (CEC), total nitrogen (total-N), and available phosphorus (available-P), measured at 14 and 56 days after application (DAA). Results showed that the effectiveness of silica humate varied depending on the type of industrial waste and increased over time. On land contaminated with pharmaceutical waste, silica humate increased CEC from 44.34 to 52.52 cmol(+)/kg and available-P from 27.21 to 36.69 ppm at low doses. Land contaminated with animal feed waste showed the best results at a dose of 20 kg/ha, while land contaminated with paper industry waste required higher doses. These findings suggest that silica humate is promising as a viable soil amendment strategy, though optimal dosage rates must be tailored to specific industrial contamination types for maximum rehabilitation effectiveness.

Abstract

Nutrients in sandy soil are limited due to low absorption capacity and are easily leached or evaporated. Biosilica and humic acid extracted from compost and husk ash can improve the soil structure and absorption capacity to optimize the availability and uptake of nutrients. Therefore, this research aims to examine the optimal application dose of biosilica and humic acid to improve the chemical properties of soil with a sandy texture. The experiment was structured based on a completely randomized design (CRD). Factor 1 consisted of biosilica doses of 0, 0.5, 1.0, and 1.5 tons ha-1, while factor 2 comprised humic acid doses of 0, 20, 40, and 60 kg ha-1. Data analysis was performed using ANOVA, followed by Tukey’s Honest Significant Difference (HSD) test, correlation, and determination analysis. The study results indicate that the combination of biosilica and humic acid contributes to the changes in nutrient availability. The impact of the treatment was observed 90 days after application on the parameters of soil pH, organic C, total N, and exchangeable K. The effects of the treatment were also evident in plant nutrient uptake, specifically in total N in the roots and total K in the stems. The optimal combination for improving soil nutrient availability and nutrient uptake in plant tissues was a biosilica dose of 1.0 tons ha-1 (S2) and humic acid at 40 kg ha-1 (H2).

Abstract

Using manure in the form of liquid organic fertilizer (LOF) influences the heavy metal levels absorbed by plants, which can affect both plant quality and human health. This research aims to assess the impact of LOF on soil pH, total nitrogen, available phosphorus, lead levels, and the fruit yield of tomatoes. A factorial completely randomized design (CRD) was employed, with the first factor being three types of LOF from chicken, goat, and cow manure and the second factor being three doses of LOF: 5, 10, and 15 mL. The study utilized tomato plants grown in latosol soil. Results indicated that the application of LOF from the three manure types affected soil nitrogen, soil lead, and tomato yield. The addition of LOF also influenced lead content and tomato production. However, the use of chicken manure is not recommended due to high lead accumulation in soil and plants. The optimal LOF dose was found to be 5-10 mL, which maintained lead levels within safe limits. The best tomato fruit yield was achieved with 5 mL of goat manure LOF, resulting in low metal accumulation.

Abstract

Continuous use of Sipramin fertilizer can lead to sodium (Na+) accumulation in the soil. Sodium accumulation damages soil physical properties, which also affects the chemical quality and nutrient supply. This study aimed to evaluate the effects of various doses of humic acid and nitrogen fertilizer sources on soil chemical properties. This study was arranged in a factorial completely randomized design (CRD) with 2 factors: humic acid doses (0, 20, 40, and 60 kg ha-1) and nitrogen fertilizer types (control, NPK Phonska, Urea, KNO₃, and MAP) with a recommended rate of 92 kg ha-1. The study consisted of 20 treatment combinations with 3 replications, yielding a total of 60 experimental units arranged randomly. Soil samples were collected at 7 and 21 days after treatment (DAT) to analyze pH, organic C, cation exchange capacity (CEC), exchangeable Na, and available N (NH₄⁺ and NO₃-). The results showed that the interaction between humic acid and nitrogen fertilizer did not significantly affect the chemical properties of the Sipramin-affected soil. In general, the effects of both treatments depended on the parameters and the time of observation. At 7 DAT, several variables showed significant effects, whereas at 21 DAT, some of those effects were no longer significant.
