Tidal swamp land is an important resource in providing rice in the border area of Sambas Regency, West Kalimantan-Malaysia. However, rice production capacity in tidal swamp land is still low. Applying appropriate and balanced fertilizers tailored to the unique nutrient requirements and salinity levels of tidal swamp soil can support optimal paddy growth and productivity. Therefore, this study was conducted to determine the combination of fertilization and amelioration application on the growth and productivity of rice in tidal swamp land with a type C overflow. The study tested the treatment of amelioration (without lime/A0; CaCO3/A1; and (Ca, Mg)(CO3)2)/A2) and fertilization dose (based on farmer and recommendation) in Tebas Sungai Village, Tebas District, Sambas Regency, West Kalimantan. The treatment was arranged in a split-plot design consisted of amelioration methods as main plot while fertilization dose as suplot. The results showed that plant growth, yield components, and productivity were influenced by lime source and fertilizer dose. The highest productivity (5.62 tons ha-1) was obtained from the plot treated with CaCO3 and fertilized according to the recommendation.

Coastal acid-sulfate soils are crucial for producing crops and thus, for food security. However, over time, these soil resources experience degradation, leading to higher agro-input, lower yields, and environmental hazards that finally threaten food security. The optimal use of this fragile resource is only attained by implementing vigorous integrated water–soil–crop management technologies amid the climate change impact. This study aimed to review the distribution, properties, use, and management of acid-sulfate soils in Kalimantan, Indonesia. Acid-sulfate soils cover about 3.5 Mha of the coastal area in Kalimantan and have high acidity, high-risk iron and aluminum toxicity, and low fertility, requiring precise water management, amelioration and fertilizer application, crop variety selection, and rice cultivation technologies. Lime, biochar, organic fertilizer, compost, ash, and fly ash are ameliorants that raise pH, reduce iron and aluminum toxicity, and improve crop yield. Rice cultivation has developed from traditional to modern but needs re-designing to fit local conditions. Depending on the soil nutrient status, rice cultivation requires 80–200 kg ha−1 of urea, 50–150 kg ha−1 of SP36, 50–150 kg ha−1 of KCl, and 125–400 kg ha−1 of NPK compound fertilizer, but is affected by CH4 and CO2 emissions. Good water management impacts the effective implementation of amelioration and fertilizer application technologies. The remaining challenges and future directions for water management, amelioration, fertilizer application, crop varieties, cultivation techniques, land use optimization, climate change adaptation and mitigation, technology adoption and implementation, and resource conservation are outlined. Acid-sulfate soils remain a resource capital that supports food security regionally and nationally in Indonesia.

“…The dolomite treatment was significantly different from without dolomite treatment on the parameters of rice yield components. Control treatment showed that the plants could not grow properly and were unable to produce panicles and grain [12,13]. The application of micronutrient fertilizers affected shoot weight at a dose of 4 g L -1 .…”

Soil acidity, availability of P, base cations, micronutrients such as Cu and Zn, and climate change have become limiting factors in nutrient management on acid sulfate soils. Therefore, applying dolomite and micronutrient fertilizer is required to improve rice productivity and climate change adaptation. This study aims to determine the effect of dolomite, Cu, and Zn fertilizers on the growth and yield of rice in acid sulfate soils. The study was conducted in the greenhouse using a completely randomized design with seven treatments and four replications. The treatment consisted of control, 3 tons ha-1 dolomite application, and 4 levels of Cu and Zn fertilizer doses 0, 2, 4, and 6 g L-1. NPK as basal fertilizer was applied according to the recommended dose for all treatments. Observations included soil pH, dissolved Fe, plant height, number of tillers, number and weight of panicle, dry shoots weight, 1000 grains weight, yield, and nutrient uptake (N, P, K, Fe, Cu, and Zn). The results showed that applying dolomite 3 tons ha-1 significantly increased soil pH, growth, and yield of rice, but applying Cu and Zn fertilizers without dolomite cannot support the growth of rice. Combination of dolomite 3 tons ha-1 with Cu and Zn fertilizers 4 ml L-1 increased nutrient uptake of N, P, K, Cu, and Zn in grains around 16% - 35% compared to without micronutrient fertilizers. Applying a combination of dolomite and micronutrient fertilizers can increase soil productivity on acid sulfate soils, nutrient uptake, and increase rice yield.
