Abstract. The objectives of this study were: (1) to evaluate the effect of air-drying or air-drying and rewetting on microbial biomass carbon (MBC), extracted organic carbon (EOC), basal soil respiration (BSR), the evolution of the respiration process (ERP) and β-glucosidase and β-galactosidase activities in ten native soils with minimal anthropogenic disturbance in Catalonia (NE Spain); and Cited by: 2.
In fact, baling was the only treatment that caused soil loss in spring of ( kg m −2) under an average % residue cover and in spring ( kg m −2) under an average % residue cover. Soil loss simulated under the residue cover associated with the baled plots was much lower than soil loss without residue by: Introduction.
This Brief Report includes a single-finding that is reported with descriptions of an unexpected observation. Soil degradation is a major constraint of food security (Gomiero, ; Lal, ), and soil erosion represents one of the crucial intervention points for reversing soil degradation (Karlen & Rice, ).The Universal Soil Loss Equation (USLE) (Wischmeier & Smith, Author: Masato Oda, Burhanuddin Rasyid, Hide Omae.
Nitrogen (N) is a major limiting factor for sustainable and profitable crop production. However, excessive N application through fertilizers and manures can degrade soil and environmental quality by increasing soil acidification, N leaching, and emissions of ammonia (NH 3) and nitrogen oxide (NO, N 2 O, and NO 2) gases, out of which N 2 O is considered a highly potent greenhouse gas that Author: Upendra M.
Sainju, Rajan Ghimire, Gautam P. Pradhan. A laboratory study was conducted to test the effects of biochars made from different feedstocks on soil quality indicators of arid soils.
Biochars were produced from four locally-available agricultural residues: pecan shells, pecan orchard prunings, cotton gin trash, and yard waste, using a lab-scale pyrolyzer operated at °C under a nitrogen Soil and air temperature and biomass after residue treatment book and slow pyrolysis by: 6.
Biochar is charcoal used as a soil amendment for both carbon sequestration and soil health benefits. Biochar is a stable solid, rich in carbon, and can endure in soil for thousands of years. Like most charcoal, biochar is made from biomass via r is under investigation as a viable approach for carbon sequestration, as it has the potential to help mitigate global warming and.
Biomass is plant or animal material used for energy production (electricity or heat), or in various industrial processes as raw substance for a range of products.
It can be purposely grown energy crops (e.g. miscanthus, switchgrass), wood or forest residues, waste from food crops (wheat straw, bagasse), horticulture (yard waste), food processing (corn cobs), animal farming (manure, rich in.

2 days ago The global energy system needs new, environmentally friendly, alternative fuels. Biomass is a good source of energy with global potential.
Forestry biomass (especially wood, bark, or trees fruit) can be used in the energy process. However, the direct use of raw biomass in the combustion process (heating or electricity generation) is not recommended due to its unstable and low energetic properties.
The soil analysis result further revealed that the soil had low available Pat both planting and at harvesting. However, the results found an increase in available P as a result of amending the soil with soybean biomass that had treated with Bradyrhizobium and P compared with the conventional intercropping.
In this case, the soil available P Author: Tesfaye Fituma, Anteneh Argaw. INTRODUCTION. Currently, increase in food production is the one of the primary objective of all countries as world population is expected to grow to nearly billion by developing countries the population growth rate is 3% year – for food increases 1 by % year –r, food production is increasing by only % year – food production needs to increase by.

Moreover, soil samples in the depth of 15, 45, 75, and cm were taken after harvesting the second batch of tomato (tomato 2) to research the change of nitrate with soil by: 8.
Anthropogenic activities can lead to environmental degradation through alteration of soil physical, chemical and biological properties. Ellis et al. estimated that about 95% of earth's ice-free land was in wildlands and seminatural anthromes (anthropogenic biomes) in By55% of ice-free land had been transformed into rangelands, croplands, villages and densely populated anthromes Cited by: Soil temperature, soil moisture, soil pH and M.
vimineum biomass were included as covariates, to account for any plot‐level or environmental differences which may affect SOC formation or loss. Per cent clay was included as a covariate in the model run for MASOC, as clay content can correlate with MASOC formation (e.g. Schimel et al., ).Cited by: The use of the biochar co-product of pyrolysis and gasification of biomass as a soil amendment is a potential option for improving soil fertility as well as storing more carbon in soil.
Biochar recycles most of the nutrients harvested with the biomass and increases soil organic carbon levels, nutrient and water holding capacity, and is a liming.
Soil is a mixture of organic matter, minerals, gases, liquids, and organisms that together support life. Earth's body of soil, called the pedosphere, has four important functions. as a medium for plant growth; as a means of water storage, supply and purification; as a modifier of Earth's atmosphere; as a habitat for organisms; All of these functions, in their turn, modify the soil and its.
Soil bulk density was determined in duplicate from each field plot using intact soil cores after oven drying ([degrees]C, 48 h). Soil pH and EC were determined on 10g air-dried (50[degrees]C) soil in 50 mL of double deionised (DI) water, which was shaken for 1 h and left to stand overnight.
