Evaluation of a Toposequence of Soils Derived from Basalt by Fourier Transform Infrared Spectroscopy

Wilson Sacchi Peternella, Antonio Carlos Saraiva da Costa
The interaction of organic matter (OM) and clay minerals has been studied as one of the main OM stabilization mechanisms present in different soil classes. The composition of OM present in the soil in terms of humic and fulvic acids and other organic compounds, together with the surface functional groups of different minerals of the clay fraction, such as iron and aluminum oxide and hydroxides type minerals, affect the intensity of the substrate/MO ratio, thus being able to change even the size ...

Experimental Research on the Influencing Factors of Radon Concentration Measurement in Soil

Yifan Jin, Junxin Zhang, Qiushi Liu
Radon is the most accessible radioactive gas in life. The radon in ambient air mainly comes from the soil. In order to ensure the accuracy and validity of the measurement of radon concentration in the soil, the paper discusses the influencing factors of the measurement of radon concentration in the soil through the controlled variable method. On the basis of familiarity with the principle of measuring the concentration of radon in the soil, using the radon meter to study the influence of the mea...

Investigation and Analysis of Soil Radioactivity Level in Parks in a City

Qiushi Liu, Ruiyang Xu, Yaohan Hu
Using a portable microcomputer multi-channel gamma spectrometer to directly measure the radioactive content in the soil, the on-site gamma energy spectrum measurement was carried out on the soil of 7 parks in a certain city. The survey results show that the specific activity of 40k in the urban park soil ranges from 470.88 bq/kg to 640.2 bq/kg. The specific activity of 238u ranges from 26.77 bq/kg to 33.31 bq/kg. The specific activity of 232th ranges from 42.14 bq/kg to 54.72 bq/kg. The content ...

Yield, Tryptophan and Lysine Content of Two Quality Protein Maize Varieties in Two Luvisols with Bio Fertilization in Yucatan, Mexico

Jorge H. Ramírez-Silva, Yolanda Moguel-Ordónez, Mónica Guadalupe Lozano-Contreras, Genovevo Ramírez-Jaramillo
This work was carried out in Yucatan Mexico aiming to evaluate the yield performance, Tryptophan (Trp) and Lysine (Lys) contents of two quality protein maize varieties (Sac Beh and Chichen Itza) growing in two Luvisols with low (Lot 1) and high (Lot 2) intensive agricultural use. Six treatments resulted from combining the two varieties with chemical fertilizers (60-80-00):(N-P205-K2O) alone or supplemented with biofertilizers (60-80-00 Mycorrhizae Azospirillum) and the control (00-00-00). Th...

The Potential Productivity of Light-Chestnut Soils of the North-Western Precaspian Region in Connection with the Dynamics of Environmental Factors

Gasan Gasanov, Tatiana Asvarova, Kamil Hajiyev, Rashid Bashirov, Aishat Abdulayeva, Zaira Akhmedova, Shamil Salikhov, Nurjagan Ramazanova, Viktoria Semenova, Radjab Usmanov, Aytemir Aytemirov, Nurulislam Magomedov, Magomed Musaev
The data on receipt of photo synthetically active radiation (FAR) on the soil surface and the coefficient of its use over the years and periods of the year de-pending on the hydrothermal conditions and dynamics of harmful salts in the soil are given. The items of the changes in the species composition of phytoce-noses depending on the environmental factors are considered.

Review on: The Effect of Mixing Organic and Inorganic Fertilizer on Productivity and Soil Fertility

Tesfaye Burju Roba
Depletion of soil fertility is a main problem to sustain agricultural production and productivity in many countries. The use of inorganic or organic fertilizer alone has both positive and negative effects on plant growth, nutrient availa-bility and the soil. Organic fertilizer improves physical and biological activities of soil but they have comparatively low in nutrient content, so larger quantity is required for plant growth. Ho

Linking Soil Conservation in Potato Production Systems in the Highlands of Southwestern Uganda to Gender and Farmer-Market Types

Robert Muzira, John Steven Tenywa, Twaha Basamba
Rural communities in sub-Saharan Africa develop different livelihood strategies driven by opportunities and constraints encountered in existing biophysical and socioeconomic environments. A study on gender effects under two market linkages on investments in soil conservation innovations in potato production systems was conducted in the highlands of southwestern Uganda. There were significant differences in lan

Microbial Inoculants Development for Bioremediation of Gasoline and Diesel Contaminated Soil

Aline Jaime Leal, Edmo Montes Rodrigues, Rita de Cássia Rocha Fernandes, Arnaldo Chaer Borges, Aline Daniela Lopes Júlio, Fernanda de Souza Freitas, Marcos Rogério Tótola
In this study, we describe the development of microbial inoculants for the bioremediation of hydrocarbon-contaminated soils through the enrichment of hydrocarbonoclastic populations in municipal solid waste compost (MSWC). Respirometric analyses were performed along with quantification of total heterotrophic bacteria and ester-linked fatty acid methyl ester (EL-FAME) profiling of the microbial communities o

Assessment of Soil Nutrients Limiting Sustainable Potato Production in the Highlands of South-Western Uganda

Robert Muzira, Twaha Basamba, John Steven Tenywa
Soil fertility management is one of the major strategies for improving potato productivity in the highlands of south-western Uganda. Land belonging to potato farmers is highly fragmented hindering sustainable potato production under small-holder farming systems. Land fragmentation brings a major challenge to small-scale farmers in soil fertility management, increasing costs of production. However, identifying major soil nutrients

Impact of Different Methods of Soil Sampling and DNA Extraction on the Identification of Soil Bacterial Abundance under Elevated CO2

Fengxia Li, Saman Bowatte, Paul C. D. Newton, Dongwen Luo
Elevated atmospheric CO2 (eCO2) is anticipated to have marked effects on soil microbial populations. While there is experimental evidence to support this view there are also studies where changes in microbial populations, such as the abundance of bacteria, are suggested but cannot be statistically established. We conducted this study
