This study was conducted to examine the soil fertility of the Büyük Menderes Basin, where wheat is widely cultivated. Soil samples were taken from 50 different points at a depth of 0-30 cm and various physical and chemical properties and amounts of nutrient elements were determined. With regard to the results of the study, the soils were generally sandy-clay-loam in texture, with slightly alkaline reaction, limy, rich in organic matter and showed no risk of salinity. The examined soils were found to be insufficient as 34% for total N, 14% for available K, 26% Mg, 10% Fe, 94% Zn and 98% Mn contents while all of the soils were determined as sufficient in terms of available P, Cu and Ca contents. When relationships between nutrient elements and soil physical-chemical properties were examined, negative correlations were found between soil pH and EC, organic matter, total N, available K, Zn; lime contents and available Mg, Fe, Cu; clay and available K and Mn contents. The positive correlations were found between EC and available K, Ca and Zn; organic matter % and total N, available K, Cu, Zn and Mn; sand % and available Mn; clay % and available Fe contents. Investigation of relationships between plant nutrients demonstrated that, there were positive correlations between total N and available K, Cu, Zn, Mn; available P and Zn; available K and Cu, Zn, Mn; available Ca and Fe; available Mg and Fe, Cu; available Fe and Cu, Mn; available Cu and Mn contents. The results of the study showed that attention should be paid to fertilization programs to fertilization with Zn and Mn, which were found to be insufficient in the greater part of the basin’s soils, and also to nitrogen deficiency is observed, as this directly affects the protein content of wheat.

Sewage sludge refers to a nutrient-rich by-product and organic matter from treatment plants and has become a challenge for many research segments to find a rational and sustainable destination for this material. In this context, the carbonization of biomass (by the pyrolysis process) results in biochar, characterized by a very stable material with specific physical and chemical properties and can represent a very important tool for this challenge. Thus, the objective of the present work was to transform, bypyrolysis process, small portions of the biosolid generated in Rancharia ETE into biochar. In addition, both the biosolid and the generated bicarbons were subjected to physical, chemical and structural analyzes in order to proceed with their respective characterization. From the analysis, it was found that the treatment submitted to temperature of 550°C as the best option for possible applications.Keywords:biosolid; pyrolysis; biochar.

In this study, soil pH, organic matter, total N, total P, total K, alkali-hydrolyzable N, available P, available K, number of microorganism and enzyme activity were studied in a burnedE. urophyllaforest (the burned forest) and an unburned adjacentE. urophyllaforest (the control) in Dongyuan County, Guangdong Province, China. This study aims at investigating the effects of a single wildfire on soil properties of anE. urophyllaforest to provide basis for the recovery of soil fertility and management of burnedE. urophyllaforests. Significant differences were observed between the burned forest and the control in most of chemical properties. The wildfire significantly decreased the soil organic matter, total N, total P, total K, alkali-hydrolyzable N and available K by 32.8%, 33.6%, 36.8%, 35.2%, 25.0% and 28.5%, respectively. However, no significant difference was observed in soil pH and available P. The numbers of bacteria and fungi in burned forest were significant lower than those of the control, while there was no difference in actinomycetes between the two forests. The urease, phosphatase and catalase activities were statistically significant lower than those of the control. The results suggested that there were significant effects on theE. urophyllaforest 1 year after the wildfire and the recovery from the wildfire may take a long time.

Organic farming is one of the management strategies that improve productivity of marginal uplands. The study aimed to: (1) evaluate effects of various organic-based fertilizers on the growth and yield of corn; (2) determine the appropriate combination for optimum yield; and (3) assess changes on the soil physical and chemical properties. Experiment was laid out in Randomized Complete Block Design, with 3 replications and 7 treatments, namely; T0=(0-0-0); T1=1t ha-1 Evans + 45-30-30kg N, P2O5, K2O ha-1; T2=t ha-1 Wellgrow + 45-30-30kg N, P2O5, K2O ha-1; T3=15t ha-1 chicken dung; T4=10t ha-1 chicken dung + 45-30-30kg N, P2O5, K2O ha-1; T5=15t ha-1 Vermicast; and T6=10t ha-1 Vermicast + 45-30-30kg N, P2O5, K2O ha-1. Application of organic-based fertilizers with or without inorganic fertilizers promoted growth of corn than the control. But due to high infestation of corn silk beetle(Monolepta bifasciata Horns), its grain yield was greatly affected. In the second cropping, except for Evans, any of these fertilizers applied alone or combined with 45-30-30kg N, P2O5, K2O ha-1 appeared appropriate in increasing corn earyield. Soil physical and chemical properties changed with addition of organic fertilizers. While bulk density decreased irrespective of treatments, pH, total N, available P and exchangeable K generally increased more with chicken dung application.

Soil, itself means Soul of Infinite Life. Soil is the naturally occurring unconsolidated or loose covering on the earth’s surface. Physical properties depend upon the amount, size, shape, arrangement, and mineral composition of soil particles. It also depends on the organic matter content and pore spaces. Chemical properties depend on the Inorganic and organic matter present in the soil. Soils are the essential components of the environment and foundation resources for nearly all types of land use, besides being the most important component of sustainable agriculture. Therefore, assessment of soil quality and its direction of change with time is an ideal and primary indicator of sustainable agricultural land management. Soil quality indicators refer to measurable soil attributes that influence the capacity of a soil to function, within the limits imposed by the ecosystem, to preserve biological productivity and environmental quality and promote plant, animal and human health. The present study is to assess these soil attributes such as physical and chemical properties season-wise.

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.

The amount of mango production in Indonesia is quite high, but the quality of postharvest mangoes is still quite low. The quality of the fruit will decline due to contamination; one of the contaminants is fungi. The way to reduce the damage of postharvest products is by coating applications. The purpose of this study was to study the physical, chemical and antifungal activities of harumanis mangoes’s quality which had been given coating during storage that could cause postharvest losses of harumanis mangoes. There are 3 treatments, each of them are respectively the provision of corn based coating  6% tobacco extract, 8% tobacco extract and 10% tobacco extract. The physical and chemical properties of the antifungal coating of tobacco extract made from corn coating for post-harvest damage on harumanis mangoes were obtained by weight loss, texture, colour, respiration rate, vitamin C and total dissolved solid. Preventing coating can prevent damage after harvest and protect the harumanis mango; therefore the quality of the mangoes can be maintained. The best results from the priority with the largest diameter inhibition zone were given corn starch 10% tobacco extract. Then the higher the concentration of extract used, the greater the diameter of the inhibition zone obtained. Based on all the tests performed (physical, chemical, and antifungal) the best treatment from the treatment was obtained that consisted of mangoes with antifungal layers of corn starch 10% tobacco extract. Because the P3 obtained the best results in maintaining physical, chemical content and fungi for 15 days.

The effect of replacing shortening and sugar on the physical and chemical properties of mangaba ice cream and its acceptability were evaluated. Ice cream formulations were tested with the following fat replacers: Selecta Light, Litesse, and Dairy Lo and the following sugar substitutes: Lactitol and Splenda. All formulations were subjected to physical, chemical, and microbiological analyses and evaluated by acceptability tests. In the sensory analysis, it was observed a larger acceptance of the formulations containing Selecta Light (SL) and the combination of Litesse, Lactiol, and Splenda (LLS). The largest reduction in total energetic value (50%) was observed in the formulation LLS. The use of fat and/or sugar substitutes caused a reduction in the air incorporation (overrun) and affected viscosity. The highest melting speed was observed in the formulation with Dairy-Lo, Lactitol, and Splenda. All formulations showed good levels of global acceptability and appearance. The substitution of shortening for fat replacers caused a reduction in air incorporation and changes in ice-cream viscosity. The low-fat mangaba ice-cream elaborated with Selecta Light was the best formulation in terms of viscosity and air incorporation when compared with the control. It also showed a good level of acceptability and low fat content.

Crop-livestock integration represents an interesting alternative of soil management, especially in regions where the maintenance of cover crops in no-tillage systems is difficult. The objective of this study was to evaluate soil physical and chemical properties, based on the hypothesis that a well-managed crop-livestock integration system improves the soil quality and stabilizes the system. The experiment was set up in a completely randomized design, with five replications. The treatments were arranged in a 6 x 4 factorial design, to assess five crop rotation systems in crop-livestock integration, and native forest as reference of soil undisturbed by agriculture, in four layers (0.0-0.05; 0.05-0.10; 0.10-0.15 and 0.15-0.20 m). The crop rotation systems in crop-livestock integration promoted changes in soil physical and chemical properties and the effects of the different systems were mainly detected in the surface layer. The crops in integrated crop-livestock systems allowed the maintenance of soil carbon at levels equal to those of the native forest, proving the efficiency of these systems in terms of soil conservation. The systems influenced the environmental stability positively; the soil quality indicator mineral-associated organic matter was best related to aggregate stability.
