Coal fly ash is a soil amendment that can be used to improve soil productivity because coal fly ash contains essential nutrients needed by plants. However, coal fly ash also contains heavy metals. This study was at a time to explore the effect of coal fly ash on soil chemical properties and lead uptake by vetiver plant (Vetiveria zizanioides L.). Treatments tested were applications of six proportion levels (0, 2.5, 5., 10, 15, and 30% by weight). The seven treatments were arranged in a completely randomized design with three replicates. The result showed that the coal fly ash had a significant effect on soil pH, total-P, total-N, total-K and Pb. The value of the Pb translocation factor from the roots to the shoot of the vetiver plant was relatively low, so that the vetiver plant was not suitable for use in phytoextraction of Pb from Pb-contaminated soil.

The increment of peat soil productivity meets through ameliorant addition. Ameliorant sources can be obtained from oil palm plantation and electric steam power station waste. The study aimed at investigating the ability of the oil palm fruit empty bunch (OPFEB) biochar, palm oil boiler ash (POBA) and coal fly ash (CFA) as alternative ameliorants besides compost to improve nutrient availability in peat soil of Central Kalimantan. Treatments tested were OPFEB biochar, POBA, CFA, compost, OPFEB biochar+compost, POBA+compost, and CFA+compost. The seven treatments were arranged in a completely randomized design of single factor with four replications. The results revealed that the ameliorants increased peat soil pH at a rate of 0.7 compared to those in initial soil used and available P of 135.7% even though there was no significant increment of exchangeable cations of K, Ca and Mg. Mixing of biochar, POBA or CFA with compost improved nutrients availability in peat soil.

The soil physical and chemical properties of four densities (A:2500/hm2，B:3300/hm2，C:4400/hm2，D:6600/hm2) of hybrid Larch plantations, Larix olgensis plantation(E) and Quercus mandsurica forest(F) were studied in Jiangshanjiao forest farm of Heilongjiang province of China. Soil bulk density, soil porosity, total N, total P, available N and available P were affected significantly by plantation density in hybrid Larch plantations. The lowest surface soil bulk density was in density 2500/hm2. Soil porosity of density 2500/hm2and 3300/hm2was bigger than that of density 4400/hm2and density 6600/hm2. Total N, total P and available N of density 4400/hm2and 3300/hm2were higher than that of density 6600/hm2and density 2500/hm2. Total N, total P, available N and available P of hybrid Larch plantations were not lower than that of Larix olgensis plantation. The results of the soil physical and chemical properties under different densities of hybrid Larch plantations and different types of forest seems to confirm that hybrid Larch plantation did not decreased the soil fertility, and the hybrid Larch plantation with densities of 3300/hm2and 4400/hm2could be conductive to improving the soil quality. The results would provide the theories basis for manage the hybrid Larch plantations.

Biochar Amendment

A study was conducted to investigate the impact of biochar amendment on chemical properties and corn nutrient uptake in a sandy Podzol soil. Four rates of biochar (0, 5, 10, and 15 g kg−1) and two rates of inorganic fertilizer (0 and local recommendation rate for corn) were randomly applied to a completely randomized design with four replicates. Corn was grown for 45 d in a glasshouse using sandy Podzol. The increase in pH of the soil was concomitant with a decrease of exchangeable Al. The fertilized soil significantly increased total N, with a concomitant decrease in soil pH due to a N nitrification. Positive changes did occur in the soil due to biochar application, leading to a significant increase in dry matter yield and corn height. Corn N and K uptakes were significantly increased by the addition of biochar, but the same was not true for Ca and Mg. However, it was found that the concentrations of N, Ca, and Mg in the corn tissue were still lower than their critical level. Our results demonstrate that application of biochar alone is not able to supply enough nutrients for the healthy growth of corn.

This study aims to determine the effect of Petro Gladiator® probiotic on the growth of earthworms (Lumbricus rubellus), in terms of the length and weight of earthworms to determine the compost produced from probiotics and earthworms (Lumbricus rubellus). This study used a Completely Randomized Design (CRD) with 3 treatments and 4 replications. The sample of this study is 3 kilograms of earthworms with hand sorting. The results showed that administration of Petro Gladiator® Probiotic has a significant effect (α <0.05) on the increase in total body length of earthworms, while from the weight gain of compost in treatment of different Petro Gladiator® probiotic, there was no significant difference with the Tuket test (α = 0.05). The administration of probiotics significantly (α <0.05) increased the percentage of total N and P content, and decreased total K content. The addition of Petro Gladiator® probiotics has an effect on the length and weight of earthworms. The addition of Petro Gladiator® probiotics also improves the quality of compost, N-total, P-total, organic matter and decreases the C / N ratio.

ABSTRACTAnalyse of soil chemical properties in the encriment of oil palm production on sandy soil at Selangkun oli palm plantationSoil is one of basic components in the development of oil palm plantation. Limitation of land causes many companies expand their areas to the sub-optimal land, such as sandy soil. This research was aimed to analyzed chemical soil properties and its relation with bunch number and bunch weight in oil palm plantation, Arut Selatan sub-district, Central Kalimantan. Survey was made in sample points that were determined based on grid system, and each sample was taken in the depth of 30 cm. This research was descriptive and used double regression equation with backward-stepwise method. Several parameters have been analyzed, such as pH, organic carbon, CEC, total N, total P, P-availability, K, Ca, Mg, Cu, Zn, Mn, and B. The result showed that the pH was categorized acid, macro nutrients were medium to very low, except total P and P-availability, while micro nutrients were enough, except boron which had very high amount. Furthermore, statistical analysis showed that some chemical properties, such as total N, CEC, and exchangeable Al were parameters which influenced production of bunch number per oil palm plant.Keywords: Oil palm, Soil nutrient, Sandy soilABSTRAKTanah merupakan salah satu komponen dasar dalam pembangunan perkebunan kelapa sawit.

Gromoxone 267 SL Herbicide (GH) is widely used in weed control, and its contamination in the soil has the potential for contamination in agricultural land. The purpose of this study was to explore the effect of the application of soluble Gromoxone 267 SL herbicide on changes in the chemical properties of Inceptisols. This study used a completely randomized design with 4 treatments and 3 replications, namely A = 0% R (0.00 mL GH 7.34 mL H2O); B = 50% R (0.03 mL GH 7.34 mL-1 H2O); C = 100% R (0.06 mL-1 HG 7.34 mL-1 H2O) and D = 150% R (0.09 mL HG 7.34 mL-1 H2O), where 100% recommended soluble Gromoxone 267 SL herbicide (soluble) is assumed to be equivalent to (~) 100% Paraquat Dichloride (276 g L-1) in the Gromoxone 267 SL herbicide. The results of this study showed that 150% application of the recommended soluble Gromoxone 267 SL herbicide had a very significant effect on reducing CEC, total N, K, Ca and Mg-dd. It also had a significant effect on organic C and N of Inceptisols compared with control or without application of Gromoxone 267 SL herbicide.
