And Chemical Properties

<p>Soil application of raw winery wastes is a procedure of doubtful appropriateness, mainly because of waste properties, i.e. very acidic pH; high electrical conductivity; and high content of polyphenols. The disposal of winery waste on soils may cause various environmental and health hazards as for example soil overloading with polyphenols and salts, phytotoxicity to plants, odor nuisance etc. Pathogens, which may still be present in the decomposed material could spread plants and soil diseases, while waste piles attract insects, pests, domestic rodents and wildlife which may threaten public and animal health. Despite these facts, many wine producers discharge winery waste to the nearby agricultural or forest ecosystems, without treatment although this type of agricultural waste could be a significant source of organic matter and nutrients.</p><p> </p><p>In general, degradation of winery waste is a slow procedure which becomes even slower under the xerothermic climatic conditions in Greece, which may slow down the microbially mediated decomposition of organic matter and nutrients cycling; degradation of winery waste piles takes more than 5 years to be completed naturally. However, the final products are of doubtful appropriateness for fertilization use, mainly because of low quality organic matter and low nutrients content (lost mainly due to the exposure of piles to uncontrolled environmental conditions for years).</p><p> </p><p>This study aims to highlight the advantages of composting winery wastes by using also other agricultural wastes and additives as feedstock to produce a safe and environment friendly compost, appropriate for application to agricultural ecosystems. For this a 41 hectares vineyard in North Greece of about 400 tn grapes yield annually and generation of approximately 100 tn of waste was selected. Winery waste was collected after harvesting and wine-making period of 2018 and composted with cow manure, wheat straw and clinoptilolite up to 5%.</p><p> </p><p>Composting phase lasted 5 months, and during this period the pile was monitored as regard temperature, moisture and oxygen content. After composting completion, the final product was fully characterized in terms of its physical and chemical properties, considering national legislation organic materials reuse on soils. The outcomes of this study show a great potential for managing such waste types by composting using clinoptilolite in the feedstock materials since the final product has suitable physical and chemical properties for many crops, i.e. slight alkaline pH, low electrical conductivity, low polyphenol content and high content of available nutrient, therefore can be used as soil amendment or organic fertilizer.</p>

Soil physical and chemical properties play a central role in plant growth, influencing the availability of air, nutrients, and water. The aim of this two-year study was to evaluate the effect of soil texture and chemical properties (pH, electrical conductivity, organic carbon, organic matter, total, and active lime) on saffron (Crocus sativus L.) growth, yield, and quality. Corms were planted in pots filled with seven different soil textures obtained mixing an increasing quantity (33% and 66%) of sand to a clay soil (S1) and to a clay loam soil (S2) compared to a full (100%) sandy soil as a control (S7). A randomized complete block design comprising of seven pots with different types of soil (S1, S2, S3, S4, S5, S6, and S7) replicated three times was used. The results showed that the highest flower number (320.3 n m−2), stigma yield (2.0 g m−2), daughter corm production (7.9 kg m−2), and horizontal diameter (3.1 cm) were derived from S3 and S4 soils. These were characterized by a loam and sandy-loam texture, not very calcareous, with a sub-alkaline and neutral pH, low electrical conductivity, a content of organic matter between 5.46 and 8.67 g kg−1, and a content of active lime between 21.25 and 26.25 g kg−1. According to International Organization for Standardization (ISO) references, although all spice samples belonged to the first qualitative category, S1, S3, and S2 soils recorded the highest value for coloring power (290.5, 289.1, and 287.6 A1%1cm 440 nm, respectively). The highest values of bittering (109.2 A1%1cm 257 nm) and aromatic (26.6 A1%1cm 330 nm) power were reached by S3 soil. Positive correlations were found both between color with clay and organic matter, and aroma with total calcium carbonate. In conclusion, the assessment of soil conditions is particularly important to obtain the best saffron performance in terms of stigma and daughter corms yield as well as spice qualitative traits.

The aim of this study was to evaluate the effect of two organic wastes used as soil amendments i.e. filter mud cake (FMC) and vinasse (V) on some physical and chemical properties of sandy and loamy sandy soils. Applications of organic were incubated with the soils for a three periods of 15, 30 and 60 days at four application rates (0, 0.5, 1 and 2%). This study was carried out in a two way randomized completely block design with three replications. After incubation periods, bulk density, porosity, water retention, soil pH, electrical conductivity (EC) and organic matter were determined. Results showed that the values of soil bulk density and soil pH were decreased with increasing the application rates of filter cake or vinasse compared with the control in two soils. In addition, application of different filter mud cake and vinasse rates to the study soils increased soil porosity, field capacity (FC), wilting point (WP), available water (AW), electrical conductivity (EC) and organic matter contents (OM) as compared to control at different period incubation time. The data of this study concluded that, organic wastes or byproducts of sugar industries could be applied to improve some soil properties.

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.

One hundred and thirty-seven samples of agricultural residue were taken from the study area of forty subdistricts in twenty districts of ten provines in the Northeastern region of Thailand. The samples were analyzed for major physical and chemical properties and subjected to simulated burning. Rice straw had the highest dry weight and bagasse the lowest. Bagasse had the highest moisture content and the highest carbon content. Results from simulated burning found that sugarcane leaf emitted more CO2 than the other residues. Weight loss on combustion was in the range of 75-92 %, and the simulated burn of agricultural residues showed CO2 emission values at 67% of the IPCC values.

Alluvial soils on the Tanana River floodplain near Fairbanks, Alaska, were examined for development of physical and chemical properties in relation to soil depth and across a 200-year vegetation development sequence. Development was mediated by ecosystem controls including successional time, vegetation, terrace height, soil physical and chemical properties, and microclimate. These controls interact and are conditioned by the state factors time, flora, topography, parent material, and climate, respectively. On early-successional (<5 years) lower alluvial surfaces, terrace height above groundwater, soil particle size, and microclimate (through soil surface evaporation) interacted through capillary rise to produce salt-affected surface soil. Calcium salts of carbonate and sulfate were the principal chemicals encountered in these soils. Establishment of a vegetation cover between 5 and 10 years introduced evapotranspiration as a new mechanism, along with capillarity, to control moisture suction gradients. In addition, newly formed surface litter layers further helped eliminate evaporation and formation of high salt content surface soil. Continued sedimentation raised terrace elevation, so on older terraces only infrequent flood events influenced soil development. Moreover, in these successional stages, only the highest river stages raised groundwater levels, so transpiration and capillarity influenced water movement to tree root systems. During the first 25–30 years of succession, plant deposition of organic matter and nitrogen, associated with the growth of alder, markedly changed soil properties. Nearly 60% (or 240 g•m−2) of the 400 g•m−2 nitrogen encountered at 100 years was accumulated during this early period. After 100 years of vegetation development, soil carbonate content dropped to about half the peak values of about 1600 g•m−2 encountered between 4 and 25 years. By the time white spruce was the dominant forest type at 180 years, carbonate carbon declined to about 500 g•m−2, one-third that of the 1600 g•m−2 high. By this time surface soil pH declined from high values of 7.5 to between 5.5 and 6.0. Organic carbon continued to accumulate to about 6300 g•m−2 in the white spruce stage, twice that encountered in the alder–poplar stage at 25 years. Indices of moisture retention were most strongly related to either soil particle size (low moisture tension and available moisture range) or vegetation-mediated soil organic matter content (high moisture tension). Cation exchange capacity was most strongly related to a vegetation-mediated index of organic matter (OM) content (%N, %C, or %OM).

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.

An Orthic Humo-Ferric Podzol formed on a sandy deposit in the St. Lawrence lowlands exhibited a weakly cemented horizon at depth. Weathering of minerals was active mainly in the upper Ae horizon and released large amounts of iron, aluminum and silica. These elements migrated down the profile as organo-metallic complexes and accumulated as concretions in the podzolic B-horizons but also in the cemented horizon at depth. Micromorphological analysis showed that this latter horizon had a chlamydic/plectic assemblage. A comparison was made with other horizons found at depth in various profiles and differing from this one by their macro- and micromorphological, physical and chemical properties. The relative content of the various constituents of the cement was calculated. The sum of organic matter plus free sesquioxides ranged from 7 to 85%. There are apparent similarities in the formation of ortstein and duric horizons. The results serve to establish the concept of "ortstein-duric horizon-fragic horizon" intergrades in weakly cemented horizons found at depth in many Quebec soils.

Grassland is an important ecosystem in land surface. Soil is the basis of grassland ecosystem, and the changes of its properties directly affect grassland ecosystem. The study region is located in Xilamuren grassland using the methods of field sampling and experimental analysis. It was divided into four test areas according to grazing intensity. Soil physical and chemical properties were analyzed in each test area. The results showed that: the trend of soil water content decreased and then increased with increasing grazing intensity, soil water content in repaired grassland was the lowest. For the soil mechanical composition, particle size content increased first and then decreased with increasing grazing intensity when the particle size was 1-0.05mm. The difference between the highest and lowest values was obvious. When the particle size was 0.05-0.002mm, the trend of particle size fluctuated, first decreased and then increased, finally reduce again and the difference between the highest and lowest values was obvious. When the particle size was less than 0.002mm, the trend of particle size content increased with increasing grazing intensity. In soil chemical properties, soil organic matter appears downward trend overall as grazing intensity increase. Soil organic matter content was the lowest in repaired grass. Available N and P first decreased and then increased with increasing grazing intensity, the minimum values appeared in the repaired grassland and degraded grassland respectively. Available K content increased with increasing grazing intensity.
