This study was conducted to determine the effects of organic materials to remediate contaminated soil with heavy metals. A pot study was performed by growing maize (Zea mays) in metal contaminated soil (10 kg pot-1) and soils amendments with cow manure dust, poultry manure dust, vermicompost dust, fern dust, water hyacinth dust, mustard stover dust and barnyard grass dust each at 5 g kg-1 soil. The results showed that Pb, Cd, Ni, Cr and Co uptake by maize depended on the organic materials type. Water hyacinth dust, fern dust, mustard stover dust, and barnyard grass dust addition led to decreased metal content in maize, and this decrease was better expressed with 20.5 to 33.3% for fern dust, 17.3 to 22.0 % for water hyacinth, 18.6 to 21.3% for mustard stover dust, 17.33 to 20.5% for barnyard grass dust. Cow manure dust, poultry manure dust and vermicompost dust led to increased metal content in the maize, and this increase was 6.80 to 18.7 % for cow manure, 18.9 to 86.7 % for poultry manure and 17.4 to 16.0 % for vermicompost. The different effectiveness of organic amendment on metal uptake by maize plant could be due to the nature of organic matter where water hyacinth dust, fern dust, mustard stover dust, and barnyard grass dust were mainly originated from plant. On the other hand, cow manure, poultry manure and vermicompost were mainly the excreta collected from cattle, poultry and earthworms. However, immobilization and phytoextraction techniques might be used to remediate soils which are contaminated with heavy metal.Bangladesh J. Agril. Res. 42(4): 589-598, December 2017

Field experiments were conducted in 2016 and repeated in 2017 to evaluate the effectiveness of Oil Palm Bunch Ash (OPBA) and Dried Poultry manure (DPM) as organic supplement, applied singly and in combination on growth properties and heavy metal uptake of cassava cultivars grown in crude-oil contaminated soil of the Niger Delta Region, Nigeria. There were four different organic amendments viz: DPM, OPBA, OPBA +DPM and control using TMS 30572, NR8082 and local variety as test crops. Results were elaborated statistically with the use of three-by-four factor variance analysis with ANOVA. Effect of various application of amendment on morphometric parameters of cultivars revealed in 2017 that at 36 weeks after sprouting (WAS), DPM and OPBA +DPM significantly (P≤ 0.05) enhanced plant heights of TMS 3572 and LV but had no influence on number of nodes, stem girth and leaf area. However, the interactions resulted in significant (P≤ 0.05) uptake and concentration of the heavy metals Fe, Cu, and Pb in leaves and Fe in roots ofTMS30572 and NR8082, indicating efficient metal removal by these varieties. Results of amendment also revealed remarkable increment in bacterial and fungal (from 104 to 106 and 103 to 104 ) populations respectively, correlating with reduction in soil total petroleum hydrocarbon (TPH) from 156.45 mg/kg to 146.73 mg/Kg. This is observed to diminish oil toxicity and improve soil status. The response of these cassava varieties to crude oil contamination appears to be optimistic. Consequently crop farmers are adviced against planting cassava and other arable crop at crude oil impacted soil for the risk of uptake of heavy metal in crop tissues.

This study sought to investigate the potential of sugarcane bagasse, poultry manure and their combination in the remediation of spent motor oil contaminated soil. About 1.5 L of spent motor oil was sprinkled on plots measuring 0.5 m x 0.5 m dimension in 12 replicate plots to simulate a major spill. Poultry dung (PD), Sugarcane bagasse (SB) and hybrid of bagasse and Poultry dung (SB - PD) were applied as organic amendments and bulking agents. The amendments were randomly administered twice within two weeks to treatment plots except the control at rate of 24tons/ha. The soil was tilled to enhance aeration and watered twice a week for 56 days. A significant decrease in Total Petroleum Hydrocarbon, TPH of 61, 53, 46 and 23% for PD, SB - PD, SB and Control plots respectively was observed. TOC and TN decreased in all the plots except the control. Soil moisture contents between 21 and 24% while soil pH within the range of 6.9 to 7.5 enhanced biodegradation process. The Total Heterotrophic Bacterial Counts (THBC) varied in all the plots while heavy metals content remained unchanged during the study. The application of these biostimulants gave promising results on hydrocarbons removal from contaminated soil.

Sandy soils are generally in need of improvement of their nutrient status. An open field pot experiment was conducted at the Gateway Fertilizer Plant, Abeokuta, Ogun State, Nigeria to evaluate the effect of various organic amendments (poultry manure, cow dung), organo-mineral and inorganic fertilizer on physico-chemical properties of sandy soil and the performance of Corchorus grown on it.Four levels of poultry manure (PM), cow dung (CD), Gateway fertilizer (GF) and organo-mineral fertilizer (OMF), at the rate of 0, 10, 20, and 30 tonnes/ha and NPK at 0, 120, 200 and 250 kg were applied. Pre-treated Corchorus seeds were planted and different agronomic data collected at pre-determined days after planting.Results obtained indicated significant differences (p < 0.05) between the treatments and yield components. PM gave the best significant value for the leaf height, leaf length and stem girth. Soil chemical properties (pH, nitrogen, acidity, phosphorus, and organic carbon content) were greatly influenced by the organic amendments as follows: PM at 10 tonnes/ha, CD at 20 tonnes/ha, GF at 20 tonnes/ha, OMF at 30 tonnes/ha and NPK at 200kg/ha.From the result of the experiment, PM at 10 tonnes/ha showed the overall best performance for Corchorus, and the trend for all amendments was: PM 10 tonnes/ha > CD 20 tonnes/ha > GF 20 tonnes/ha > OMF 20 tonnes/ha > NPK 250 kg/ha on the sandy soil. The use of organic materials in improving sandy soil to promote optimum crop growth and yield of Corchorus is recommended. PM at 10 tonnes/ha, CD and GF at 20 tonnes/ha should be recommended as source of improving sandy soil if optimum production of Corchorus is desired.

Eichhornia crassipes is well-known as water hyacinth. Water hyacinth grows rapidly in the nutrient-rich water and high light intensity places. The uncontrollable growth of water hyacinth has caused many negative impacts to the environment. For instance, interrupted water transport and decreased population of aquatic lives. The capacity of utilising water hyacinth is slower than water hyacinth growth and water hyacinth is still considered as a threat to theecosystem. This work was focused on the study of the pharmacological activity and heavy metal content of water hyacinth in Lake Cipondoh, Tangerang. Fresh water hyacinth was pre-treated through oven-drying and milling process. After that, each part of the plant was macerated by using multiple extraction method with 96% ethanol/water and three variations of sample-to-solvent ratios (1:30, 1:50, and 1:75 w/v). The result of the experiment showed thatwater hyacinth leaves produced an extract with lowest IC 50 (55.76 ± 6.73 ppm) compared toother parts. The most optimum solvent used to achieve this result was 96% ethanol/water (1:1 v/v). In order to obtain the lowest antioxidant activity, the sample to solvent ratio used was 1:50 and the heavy metal in the extract was very low. With this result, it was concluded that there is a promising opportunity to apply the water hyacinth growing in Lake Cipondoh, Tangerang as herbal medicine ingredient. Through this utilization, the overall number of water hyacinth in Indonesia can be reduced or at the least be controlled, so that the environmental problem caused by this plant can be minimized.

Very High

Organic materials that are generally used as raw material for organic fertilizer granules (POG) is a natural organic material that has been degrade, smooth and dry. One of the main raw materials are always used with a very high percentage of usage, is manure. Manure potential in Indonesia is very high, amounting to 113.6 million tons per year, or 64.7 million tons per year to the island of Java. From this amount, it will be generated numbers POG production potential of 17.5 million tons per year (total Indonesia) or 9.9 million tons per year for the island of Java. While the realistic POG production predictions figures made from raw manure is 2.5 million tons annually, a figure that has been unable to meet the number requirement of POG greater than 4 million tons per year. Therefore, in producing POG, it should be to maximize the using of the potential of other organic materials so that the use of manure can be saved. With the use of a small amount of manure (maximum 30% for cow manure), it would be useful also to avoid the production of POG with high Fe content.keywods: organic material, manure, granule organic fertilizer

Azotobacter might be used as biological agents in bioremediation of heavy metal-contaminated soil since this rhizobacteria produceexopolysachharides (EPS) that mobilize soil heavy metals, and phytohormones that regulate root growth. So that heavy metal uptake bythe roots could be increased. The objective of this research was to verify the stability of EPS and phytohormones in Azotobacter liquidinoculants during four months in different temperature storage. Liquid inoculants has been produced in EPS-induced media and stored in200C and room temperature (24-270C) during four months. The results showed that the better temperature storage was room temperatureinstead of 20 0C since pH, total N, and EPS and phytohormones content was relatively stable during storage.

Biosorption is becoming an attractive alternative for the removal of heavy metal from contaminated wastewaters since it offers low capital and operating costs. It has a great potential on heavy metal decontamination and the possibility of metal recovery. The study evaluated the performance of water hyacinth (Eichhornia crassipes) in a fixed bed column on sequestering heavy metals present in wastewaters. Column breakthrough curves at varying parameters were evaluated. The study used Aspen Adsorption® to simulate the biosorption process. Analysis of breakthrough curves for the single metal system shows that increasing both influent flow rate and initial metal concentration reduces the metal uptake of the column, while increasing bed height enhances the metal uptake of the column. Presence of both Cd(II) and Cu(II) in the system promotes competitive sorption processes. Analysis of the breakthrough curves for the binary metal system showed that copper ions adsorbed to the adsorbent are replaced by cadmium ions when the maximum capacity of the column is reached. This leads to the outlet concentration of Cu(II) exceeding its initial concentration. This phenomenon shows that Cd(II) has more affinity with E. crassipes than Cu(II).
