Abstract

Low P availability is the main constraint for crops on acidic soil such as an Ultisols due to high soil P sorption. The objective of current research was to determine the effect of coal fly ash-chicken manure mixture application on P use efficiency by corn (Zea mays L.) in Ultisols. The research were arranged according to Factorial Completely Randomized Design with three replicates. The treatments tested were the rates of FA-CM mixture (w/w of 1:1) that consisted of 0, 15, 30, 45 and 60 tons ha-1, and P fertilizer rates that consisted of 0, 0.5, 1.0, 1.5 and 2.0 times of P requirement to achieve of 0.2 μg P mL-1 in soil solution (equivalence to 0, 87, 174, 261 and 348 kg P2O5 ha-1). Results of current research showed that P use efficiency by corn on Ultisols had been increased through the addition of FA-CM in combination with P fertilization at the rate of 87 kg P2O5 ha-1. The optimum rate of FA-CM in combination with P fertilizer at the rate of 87 kg P2O5 ha-1 is 28.60 tons ha-1, with P uptake efficiency of 42.41 % and agronomic P efficiency of 82.53 mg shoot dry weight/mg P from fertilizer.

Abstract

Open-pit mining has affected landscapes and ecosystem balances immensely. The effects are including altered soil surface, decreased soil productivity, soil compaction, erosion and sedimentation, declined biodiversity, as well as deteriorated hydrological, hydrogeological, and atmospheric function of the surrounding area. Reclamation is one of the environmental restoration efforts that could be taken to improve these conditions. Physical and chemical properties of soil are the indicators of soil damage level as well as the success indicator of the reclamation program. This study aims to analyze the changes in post-mining soil characteristics after 5 years and 10 years of revegetation. The sample was selected by the purposive sampling method based on the age of plants and the vegetation density. The physical properties of post-coal soil after 5 years of revegetation are characterized by high soil acidity, low in organic matter (OM)/soil organic carbon (SOC), very low total N (nitrogen), moderate P availability, extremely high K2O, and moderate CEC. Whilst, the post-coal mining soil after 10 years of revegetation is found to be acidic (low pH), with moderate SOC, low total N, low P, very high K2O, and moderate CEC. Heavy metal (Fe, Mn, Al) contents in ex-coal mining reclamation area after 5 years and 10 years revegetation found to be in the high category. Key words: post-mining land, revegetation, soil characteristics

Abstract

TITLE : CHANGES OF P SORPTION ON ULTISOL DUE TO ADDITION OF COAL FLY ASH-CHICKEN MANURE MIXTURE. High soil P sorption which result in low P availability for plants is one of important constraints in Ultisols. The objective of current research was to study the effect of coal fly ash-chicken manure mixture (FA-CM) on the changes in P sorption and availability in Ultisols. Two treatments - FA-CM mixture (w/w of 1:1) at the rate of 0, 15, 30, 45 and 60 ton ha-1, and P fertilization at the rate of 0, 87, 174, 261 and 348 kg P2O5 ha-1 - were tested. These treatments were arranged according to Factorial Completely Random Design with three replicates. Results of current research showed that FA-CM and P rates and their interaction significantly affected the values of point of zero charge (PZC), pH and soil negative charges. FA-CM mixture as a soil ameliorant decreased P sorption but it increased available P in Ultisols by increasing both soil pH and negative charges. The application of FA-CM at 30 tons ha-1 and P at 174 kg P2O5 ha-1 resulted in better increases in soil charges than any other combinations. However, the lowest P sorption (127.07 mg kg-1) and the highest available P (102.21 mg kg-1) was resulted in by the applications of 42.64 tons of FA-CM ha-1 and 261 kg P2O5 ha-1.

Abstract

Taqwa et al, 2016. The Using of Cucumbar Extract to Reduce the Stress Level and Increase the Survival Rate of White Shrimp Postlarvae (Litopenaeus vannamei) during Salinity Decreasing Time. JLSO 5(1):53-61.The purpose of this study was to evaluate the effect of adding cucumber extract on the level of stress and survival of white shrimp postlarvae during acclimatization. The method used was completely randomized design with five treatment and three replication of adding cucumber extract that equal 15 ppm (T1), 30 ppm (T2), 45 ppm (T3), 60 ppm (T4) and without adding cucumber extract (T0) as a control. The results showed that addition of cucumber extract equivalent to 15 ppm (T1) in diluents media during 96 hours of acclimatization produce survival 91.67%, body fluid glucose levels are lower at 161.67 mg dl-1 and consumption level of oxygen 4.39 mg O2 g-1 h-1. Physical chemistry value of media acclimatization still in tolerance except in ammonia

Sari OR, Jubaedah D, Wijayanti M, Marsi M. 2021. Application calcite limein peat soil to improve water pH in culture media of catfish (Pangasius sp.). In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembang 20 Oktober 2021. pp. 844-853.  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI). Application of calcite lime has been researched to be able to increase the pH of water and soil of catfish culture media. Application of lime is not only affected by soil and water pH but also affected by organic matter as in peat soil that have high carbon organic.  This research aims to know the effect of calcite lime and various C-organic on water and soil pH for culture of catfish.This research was conducted from July to December 2019 at the Laboratory of Aquaculture Experimental Pond, Aquaculture Study Program, Faculty of Agriculture, Sriwijaya University. This research use Factorial Completely Randomized Design. Thefirst factor is different dose of calcite lime that are 7000 kg/ha equivalent CaO (K1), 8000 kg/ha equivalent CaO (K2), 9000 kg/ha equivalent CaO (K3), 10000 kg/ha equivalent CaO (K4). The second factor is peat soil with different soil organic carbon that are 19.72% (C1) and 59.98% (C2). The results of this study indicated that K3C1(interaction of dosage of lime 9000 kg/ha equivalent to CaO and 19.62% C-organic) increased the initial soil pH from 3.2 to 7.43, and water pH from 3,2 to 7.33, and produces 100% survival of catfish, absolute growth of length 9.08cm and absolute growth of weight 4.60 g.
