“…The introduction of HAs also resulted in a significant increase in soil pH, which further reduced the mobility and bioavailability of iron. Similar results were reported by Herviyanti et al [95], who evaluated the effect of HAs applications (200-600 mg kg −1 ) on the iron content of flooded soils and the yield quality of rice. They obtained the best results in the series with the highest HA dose.…”

An interesting feedstock for energy purposes is plant biomass due to its renewability, widespread availability and relatively low cost. One plant with a high and versatile use potential is maize. Plants used for energy production can be grown in polluted areas, e.g., with iron. The aim of the study was to determine the effect of humic acids (Has) on the yield, calorific value and other energy parameters and chemical composition of maize biomass applied as a phytostabiliser on iron-contaminated soil. The soil was contaminated with iron at 0, 250, 500 and 750 mg kg−1. The Has were added to the soil in the following amounts: 0, 0.3, 0.6 and 0.9 g kg−1 of soil. Soil contamination with iron had relatively little effect on the heat of combustion and calorific value of biomass and very strongly reduced plant height (42%), dry matter yield (95%) and energy production of maize biomass (90%), the SPAD index at the fifth leaf unfolded stage (44%) (as opposed to the stem elongation stage), sodium, magnesium and phosphorus contents, and increased calcium, potassium and nitrogen contents of maize. The application of Has to the soil had a positive and very large effect on both the height and biomass parameters studied, resulting in an increase in plant height (22%), dry matter yield (67%) and energy production from maize biomass (62%). Changes in the heat of combustion and calorific value of the biomass were minimal but positive. Has contributed to a decrease in the value of the SPAD index during the stem elongation phase of maize and in the content of all macronutrients in maize biomass as a result of a reduction in the effect of iron on macronutrient content and to a significant increase in maize dry matter yield in plots with their application. The application of Has appears to be an effective adjunct in the phytostabilisation of iron-contaminated soils by growing crops for energy purposes.

“…Rezki, Ahmad, & Gusnidar (2007) reported that Sub-bituminous coal taken from Pasaman, West Sumatra can be used as a source of organic material because it contains HS Copyright © 2019 Universitas Brawijaya as much as 31.5% (21% humic acid and fulvic acid 10.5%) and were extracted with 0.5 N NaOH. Subbituminous coal percentage humic acid (21%) was higher than the percentage of humic acid contained from other organic materials, such as municipal solid waste compost (1.4%), manure (1.6%), rice straw compost (5%), and peat soil (9.2%) (Herviyanti, Prasetyo, Ahmad, & Saidi, 2012). Therefore, the Sub-bituminous coal as a source of HS can be used as soil organic matter to improve soil fertility.…”

“…The aplication of HS has been studied by Herviyanti, Prasetyo, Ahmad, & Saidi (2012) from the first year of research. The result showed that the highest grain yield of paddy rice was on the treatment of 800 ppm HS (1.6 t/ha) + 100% P-fertilizer recommendation (300 kg/ha) which were incubated with I 3 (the mixture of HS and P fertilizer for 1 week and then incubated to the soil for 1 week) with grain yield 5.27 t/ha.…”

“…The redox reaction is raised by poor drainage, deficiency of K, Ca, Mg, P, Zn, and Mn, as well as a low amount of soil oxygen. Newly opened rice fields that were infected by ferro toxicity can be recovered through proper water management, amelioration, fertilization, adjustment of planting time, and the use of tolerable crop varieties (Herviyanti et al, 2019).…”

Indonesian swamp has a high potency to provide areas for agricultural expansion, which means to raise food security. To optimize its utilization, government has developed new rice fields in the tidal swamp. This research was carried out in a new rice field from the tidal swamp in Bulungan District. The research aimed to optimize the new rice fields by implementing superior rice varieties (NSV). The study used a randomized block design (RBD) with three replicates. Benefit Cost Ratio (BCR) analysis was performed to determine the feasibility of rice farming in the new field. The NSV consisted of six varieties of rice, namely Inpara-1, Inpara-2, Inpara-3, Inpara-4, Inpara-5, and a local variety. The planting pattern implemented was jajar legowo (jarwo) 2:1, and seedlings were planted three stems per clump at the age of 20-25 days. Each planting treatment was given the same dose of limestone and fertilizer, namely dolomite 1,000 kg ha-1, NPK fertilizer 250 kg ha-1, and Urea 100 kg ha-1. The results showed that all varieties were able to adapt tidal swamp condition, and Inpara varieties productivity was higher than that of local variety. The productivity of superior varieties rice in a newly opened rice reached 2.6–5.75 tons milled dry grain ha-1. The findings also revealed that superior rice varieties have BCR>1, while the local variety had BCR<1. The productivity of Inpara-1 and Inpara-2 was the highest compared to other varieties and was also feasible to be cultivated on newly opened rice fields in Bulungan District.
