“…Increasing soil pH in organic soils due to dolomite application has been well studied. A pot study reported that the addition of lime doses 7.5 g kg -1 to peat soils increased soil pH from 4.14 to 5.52 (Nurhayati et al, 2014), and 3 t ha -1 dolomite increased peat soil pH from 3.7 to 4.3 (Sopha et al, 2021). The increase in soil pH was linear with the level of dolomite (Lestari et al, 2018).…”

“…The treatment without phosphorus fertilizer addition (P1, P7) had a high concentration of P, which might be due to the high concentration of total phosphorus in the soil. Lime application increased soil pH, improved phosphorus availability, and increased the available P (Sopha et al, 2021). Phosphorus is an immobile element, and the soil analysis result is highly influenced by the sampling method during the experiment.…”

Peatland degradation might affect peatland functions. Sustainable agriculture practice, i.e., nutrient management, is one of the efforts that could be made to delay the degradation. Therefore, this research aimed to identify the best nutrient management practice for shallot production in degraded peatlands. A split-plot experimental design was performed in a greenhouse environment, with cultivars (Sembrani and Trisula) as the main plot and eleven combinations of NPK fertilizer as the subplot. All treatments received 4.4 t ha-1 dolomite to increase the soil pH. Results showed that Sembrani produced a higher bulb yield than Trisula. Trisula was sensitive to acidic soils and failed to yield a high bulb. The NPK recommended dose for Sembrani was 150 kg N ha-1, 100 kg P2O5 ha-1, and 100 kg K2O ha-1, producing 57.50 g plant-1 equal to 14.4 t ha-1 or 53% higher than the control (without NPK). Meanwhile, growing Trisula was not recommended for peatlands.

“…other micronutrients and result in lower yields obtained. According to Sopha et al (2020), insufficient nitrogen supply keeps onions growing, but continues to reduce bulb size and marketable tuber yields. P deficiency in shallots will reduce root and leaf growth, tuber size and yield, but will further support optimal aging.…”

Lowland has the potential to be developed to plant shallots, given the importance of shallots in meeting the growing needs of the Indonesian people and supported by a high market share, therefore to increase the productivity of shallots in Lowland it is necessary to apply organic cow dung and biofertilizer. The purpose of this study was to determine the best organic cow dung and biofertilizer in increasing the productivity of shallots on land or in lowland. This research was conducted in Seri Tanjung Village, Tanjung Batu District, Ogan Ilir Regency, South Sumatra Province. The layout of the experiment was in polybags using a factorial randomized block design with 8 treatment combinations which were repeated 4 times. Factor 1 is organic cow dung fertilizer, namely 0, 7.5, 15, 22.5 tons/ha. Factor 2 is biofertilizer, namely without and biofertilizer. The highest production (dry weight of plant tubers) was achieved in the application of organic cow dung fertilizer of 15 tons/ha with bio fertilizers, which was 53.56 g/plant.

“…The use of lime only increased the Ca 2+ , pH, and the indigenous available P of peat [47] , while the application of manure added nutrients to the peat so that the growth and yield of liberica coffee increased significantly. Maftu'ah et al [48] also reported that using manure in combination with mineral fertilizers increased the number and weight of chilly fruits on degraded peatland. Meanwhile, Salim et al [40] showed that the use of manure of 2.5 t/hm 2 in horticultural cultivation, besides increasing crop production, can also maintain the chemical properties of peat.…”

Indonesian peatlands are a fragile ecosystem, and to protect it, growing Liberica coffee is a promising way for both the environment and the economy. This study aimed to evaluate the performance of the liberica coffee on peatland with different water tables and develop an improved cultivation system in this ecosystem. The study area was in Tanjung Jabung Barat District, Jambi Province, Indonesia. The plant age is greater than 15 years and the average plant density was about 1000 trees/hm 2 . The study was conducted in two stages. The 1st stage was a survey to identify and characterize smallholder liberica coffee farming at three peatland zones, namely 0-100 m, 200-300 m, and >400 m from the principal drainage canal, and the 2nd stage was a field experiment to test the effectiveness of amendments in improving liberica coffee growth and improving degraded peatland. The treatments were arranged in a randomized complete block design with four replications, including manure (M), at the rate of 10 t/hm 2 ; lime (L), 3 t/hm 2 ; peat surface elevation (P), and a farmer's practice (Control) without manure and/or lime as a control. This research revealed that liberica coffee can not tolerate high water table as it may stimulate disease incidence and cause low-quality yield. However, recycling of organic C of about 17.14 t/(hm 2 •a) through cherry residue application and litter compensated part of the loss of organic C through CO 2 emissions, coffee bean removal, and maintaining peat fertility for sustainable farming. The low yield of (0.70±0.12) t/(hm 2 •a) coffee bean could be increased to (0.87±0.24) and (0.94±0.14) t/(hm 2 •a) by adding 3 t/(hm 2 •3a) of lime or 10 t/(hm 2 •a) of manure, respectively. This research revealed that water table management and amendments are two main factors in liberica coffee farming on peatlands. It is of great significance to study the cultivation technology of coffee in peatland.
