The study was conducted to examine the effect of surface burn severity (Moderate, Severe and Unburned) of wheat straw on soil properties. The results showed statistical differences in some soil physical, chemical and biological properties. Bulk density and field capacity increased statistically by the severity of fire; however, porosity and infiltration rate were statistically lower in sever burned plot when compared to unburned plot. The chemical properties, soil organic matter (SOM), P, Ca, S, Cl, K, Mo, Fe and As were not affected by the fire. The pH value was increased slightly by increasing the fire severity, while, EC was decreased when compared with the unburned plot. It was found a statistical reduction in the number of bacterial and fungal cells per gram soil in the burned plots. A moderate and severe fire reduced seed germination percentage significantly. This finding suggests that fire severity may destruct the biological, physical and some of the chemical properties of the soil, and this may impact negatively on plant growth in the next growing season.

Biopore infiltration hole are hole made for run-off flow which if allowed to cause erosion and can remove the topsoil, causing soil fertility to be reduced. The use of biopori infiltration holes can be maximized by adding organic matters into the hope that in addition to absorbing water it can increase soil fertility. The liquid waste of tofu and meranti litter is an organic matters are used in this study, by adding organic matters to the biopori hole. This study aims to look at the effect of providing organic matters in the biopore hole derived from tofu and litter liquid waste on the value of pH, C-Organic, and post-mining CEC. This study was an experimental study in the field using a completely randomized design of one factor, namely organic matters with six levels, namely without organic matters and using 25 g, 50 g, 75 g, and 100 gr organic matters given to the biopori hole in incubation for one month later Soil samples taken were analyzed for pH, C-organic, and CEC. The results showed that the treatment only affected the soil's pH value. Organic material provided in the biopori hole is thought to have not completely decomposed, causing the soil around the biopori infiltration hole to remain acidic. The acidity of the soil is due to the gases produced during the decomposition process. Changes in soil pH ranged from 4.36 to 4.65 by administering 75g of organic matters from tofu liquid waste and meranti litter. This research is useful in post-mining land reclamation in increasing soil fertility, with the improvement of soil chemical properties such as pH will slowly improve the physical and biological properties of the soil so that it can be used as cultivation land.

The study was conducted at Shyamnagar and Talaupazila of Satkhira district in Bangladesh to know about the soil salinity and its relation to other properties of soil in both dry and wet season and comparison the present status of soil between two upazilas. Electrical Conductivity (EC) value of the study area showed that yield of many crops can be restricted in dry season due to salinity. Mean EC was slightly saline (5.93 dsm-1) in dry season and non- saline (0.61 dsm-1) in wet season. Ranges of pH were slightly acidic to slightly alkaline (6.2 to 7.5) in dry season and slightly acidic to neutral (5.7 to 6.9) in wet season. pH values indicate it was suitable for crop production. Mean Organic Matter (OM) status was low in both seasons (1.5 % in dry season and 1.6 % in wet season). Mean total N status was very low (0.08 %) in dry season and low (0.10 %) in wet season. Mean status of P in the study areas was low (8.08 µgg-1 soil) in dry season and very low (4.98 µgg-1 soil) in wet season. Mean status of K, Ca, Mg, S and Zn were very high in both season of study area and this was may be due to excessive fertilizer use and inherent properties of soil in the agricultural land. Mean status of B was high in Tala in both season and in Shyamnagar was high in dry season and optimum in wet season. To test the significance of the pair of parameters p-value has been measured. Pearson’s correlations among the different parameters were done to identify the highly correlated and interrelated soil quality parameters. EC showed significant and positive correlation with Potassium, Sulphur and Zinc in dry season. Although chemical properties of soil at Shyamnagar and Talaupazila was not found similar and optimum level but it was found that the chemical properties of soil of wet season more suitable than the dry season because of soil salinity.

Mikania mirantha is a pernicious world-class weed with extremely high threats to the native flora, and ranks no. 1 on the invasive alien plants list. In this study, Mikania mirantha was carbonized to form the carbide, which is called Mikania mirantha charcoal (MMC). MMC’s pH value more than 9 increases with the carbonizing temperature. Besides, MMC has many microelements consist of calcium, magnesium, potassium and silicon that are helpful to the growth of the plant. Therefore, this research is to investigate the physical and chemical properties of MMC-mixed peat media and the seedling index of the vegetable for using MMC mixed with peat media to substitute the commercial perlite peat (CPP) as culture media of the vegetable seedlings. The results showed that MMC-mixed peat media (MMC-P) whose total porosity was more than 85% were belonged to the type of lighter media. The pH value of MMC-mixed media before seeding belongs to neutrality and close weak alkali. After seeding for the 39th day, the seedling index of MMC-mixed media was 0.086-0.101, which was a little lower than that of CPP, 0.11. It resulted from a higher pH value from MMC. As a whole, MMC would be also used as the biofertilizer to improve the acid soil. This study suggests that MMC can be washed by other natural acidity media to change its pH value, which is possible to promote MMC-mixed media to substitute CPP media.

Over 2004–2006, effects of mineral fertilisers (60 N + 30 P + 60 K kg/ha or 120 N + 30 P + 60 K kg/ha) and farmyard manure (12 or 24 t/ha) application on biological and chemical properties of soil were studied in seminatural grassland. The research trial was established at Radvaň site, central Slovakia (altitude 480 m, loamy to sandy-loamy Cambisol). These parameters were investigated during the growing seasons: CO<sub>2</sub> production, intensity of total N mineralisation (TMN), the rate of nitrification (NIT), total C content in microbial biomass (MB-C), C<sub>ox</sub>, N<sub>t</sub>, P, K, Mg and the humic acids to fulvic acids ratio (HA:FA). At the application of mineral fertilisers, the highest N rate significantly increased TMN and NIT, mainly in 2004 and 2005. The manure application showed the strongest effects on the biological parameters. The manure rate of 12 t/ha significantly increased the soil respiration in 2005 and 2006 as well as TMN and NIT throughout the research. The manure application increased also the soil pH, MB-C, N<sub>t</sub>, Mg, P and C<sub>ox</sub>.

The aspects of the process of decomposition and recycling of zoogenic litter (dead animals of different classes) were first ascertained for the steppe Prydniprovia. Influence of destruction of necrotic organic matter on soil properties (pH, NPK-complex) in forest ecosystems in the steppe zone of Ukraine was estimated. Decomposition and recycling processes of dead animals (chickens, rats) on the experimental plots in biogeocoenoses with artificial oak plantations, sampling soil under dead bodies after the active stages of decomposition with different soil horizons at the same time with control samples, its chemical analysis allowed to determine the effect of degradation necrotic organic matter on the pH value and the content of some chemical elements (N, P, K) in the soil studied ecosystems. In this article the results of investigation of the effect of zoogenic litter on some chemical properties of soil in forest biogeocoenoses of steppe Prydniprovia are presented. The effect of chickens and rats corpses’ decomposition on the pH of soil, nitrogen, phosphorus and potassium indexes in the soil is analyzed. The influence of the expansion of animal carcasses on soil chemical properties in different soil horizons compared with control values (without the presence of animal carcasses) is identified. It was found that under the effect of decomposition of animals’ corpses the pH of the soil increases. Under the corpses of chickens pH increases by 6,4–16,7 %, and rats – 2,2–14,2 % compared to control values. The content of nitrogen in the soil under the corpses of chickens increases by 9,5–42,2 %, and under the corpses of rats – to 25,5–25,7 %. Phosphorus content under the corpses of chickens increases by 28,4–107,7 % of rats – to 57,5–75,7 %. The content of potassium in the soil under the corpses of chickens increased by 3,63 % to 69,8 %, and the corpses of rats – by 6,8–23,0 %. Consequently zoogenic litter is an important factor in the accumulation of NPK-complex in the soil. Thus process of animal corpse decomposition has positive effect for chemical properties of forest soil and biogeocoenoses generally.

ABSTRACT<br /><br />The imbalanced supply-demand of soybean is the main reason of soybean import in Indonesia. One of the efforts to increase of soybean production was expanding the planting area to acid soil with a low pH, high content of Aluminum, and low nutrient availability, through giving ameliorant, such as liming organic materials, and mineral fertilization.This study was aimed to obtain the best combination of fertilizer and amelioran for soybean production in acid soil. The study was conducted in experimental station of Tenjo, Bogor from November 2015 to March 2016. The experiment used a randomized complete block design with two factors. The first factor was combinations of fertilizer and amelioran, i.e., P0 (without fertilization); P1 {25 kg urea + 75 kg SP-36 + 50 kg KCl + dolomite ¼ x Aldd (805 kg) ha-1}; P2 {25 kg urea + 75 kg SP-36 + 50 kg KCl + dolomite ¼ x Aldd (805 kg) + 1,250 kg of manure ha-1}; P3 {50 kg urea + 75 kg SP-36 + 50 kg KCl + dolomite ¼ x Aldd (805 kg) + 2,500 kg of manure ha-1}; P4 {75 kg urea + 150 kg SP-36 + 100 kg KCl + dolomite ¼ x Aldd (805 kg) + 2,500 kg of manure ha-1}; P5 {75 kg urea + 150 kg SP-36 + 100 kg KCl + dolomite ½ x Aldd (1,610 kg) ha-1}; P6 {75 kg urea + 150 kg SP-36 + 100 kg KCl + dolomites 1 x Aldd (3,220 kg) ha-1}. The second factor was soybean varieties of Tanggamus and Anjasmoro. The results showed that application of 75 kg urea + 150 kg SP-36 + 100 kg KCl + dolomite ½ x Aldd (1,610 kg) produced the highest productivity (2.91 ton ha-1), but it was not different from reducing the dose of dolomite into ¼ x Aldd (805 kg) with the addition of 2,500  kg of manure.<br /><br />Keywords: Al saturation, chemical properties of soil, nutrient uptake, produktivity, soil amelioran

The aim of this study was to synthesize, characterize, and evaluate degradation and biocompatibility of poly(lactic-co-glycolic acid) + hydroxyapatite / β-tricalcium phosphate (PLGA+HA/βTCP) scaffolds incorporating simvastatin (SIM) to verify if this biomaterial might be promising for bone tissue engineering. Samples were obtained by the solvent evaporation technique. Biphasic ceramic particles (70% HA, 30% βTCP) were added to PLGA in a ratio of 1:1. Samples with SIM received 1% (m:m) of this medication. Scaffolds were synthesized in a cylindric-shape and sterilized by ethylene oxide. For degradation analysis, samples were immersed in PBS at 37 °C under constant stirring for 7, 14, 21, and 28 days. Non-degraded samples were taken as reference. Mass variation, scanning electron microscopy, porosity analysis, Fourier transform infrared spectroscopy, differential scanning calorimetry, and thermogravimetry were performed to evaluate physico-chemical properties. Wettability and cytotoxicity tests were conducted to evaluate the biocompatibility. Microscopic images revealed the presence of macro, meso, and micropores in the polymer structure with HA/βTCP particles homogeneously dispersed. Chemical and thermal analyses presented very similar results for both PLGA+HA/βTCP and PLGA+HA/βTCP+SIM. The incorporation of simvastatin improved the hydrophilicity of scaffolds. Additionally, PLGA+HA/βTCP and PLGA+HA/βTCP+SIM scaffolds were biocompatible for osteoblasts and mesenchymal stem cells. In summary, PLGA+HA/βTCP scaffolds incorporating simvastatin presented adequate structural, chemical, thermal, and biological properties for bone tissue engineering.
