This study was conducted to evaluate the population of the arbuscular mycorrhizal fungi (AMF) in the semi-rid agro-ecosystem of North Jordan and to evaluate the effect of the biotic and abiotic factors on AMF population. Soil samples were collected from 12 locations where several soil samples were collected from each location. The collected soil samples were analysed for chemical and physical p...

Humans are continuously exposed to ionizing radiation from natural sources. The main contributors to natural radiation are high-energy cosmic radiation and radioactive nuclides that originate in the earth’s crust. Rn, a decay product of Ra, originates from the naturally occurring U decay series. Rn, the only gas in the U decay series, is chemically inert, but is radioactive and exposure to it a...

Land surveys of soil attributes can provide valuable information on the geographic distribution of important soil attributes and summarize the levels found. Landscape position can have a major influence on soil attributes. Consideration of field landscape variables in selecting sampling locations and interpreting results, even in large-scale surveys, should help to reduce unexplained variabilit...

A multi-syringe flow injection system for the potentiometric determination of exchangeable potassium in soil samples is proposed. Firstly, a manifold was devised to allow determination in soil extracts prepared off-line. It was possible to analyze samples prepared in extractants with different composition (Mehlich or Morgan) without physical or chemical modification of the manifold. A linear dy...

The abundance of Pratylenchus scribneri in soil and root habitats was compared in potato and corn plots during 1986-88. Nematodes were extracted from 100-cm(3) soil samples and the roots contained within the samples. The percentage of the population recovered from soil, similar among years and crops, averaged ca. 50% at the beginning and end of the growing season and ca. 20% from early to late ...

Plant growth is directly affected by soil water, soil aeration, and soil resistance to root penetration. The least limiting water range (LLWR) is de®ned as the range in soil water content within which limitations to plant growth associated with water potential, aeration and soil resistance to root penetration are minimal. The LLWR has not been evaluated in tropical soils. Thus, the objective of...

PH (Puissance de Hydrogen) is an essential ingredient of soil that effects on fertility and productivity of dirt. Barddhaman district is a part of Lower Gangetic Plain fully covered by alluvial soil and popularly known as 'rice bowl of West Bengal' owing to its lofty production. This data article provides a block level data on soil PH that is essential for further investigation of the relations...

Photoplethysmography (PPG) devices are widely used for monitoring cardiovascular function. However, these devices require skin contact, which restricts their use to at-rest short-term monitoring. Photoplethysmographic imaging (PPGI) has been recently proposed as a non-contact monitoring alternative by measuring blood pulse signals across a spatial region of interest. Existing systems operate in...

The Data Availability Statement appearing with the published article is incorrect. The correct Data Availability Statement should read: There are legal restrictions on the student outcome data. National Child Measurement Programme data was used as determined by the data sharing agreement with the then Information Centre of the National Health Service (NHS IC), now Health and Social Care Informa...

Soil is one of the most common natural elements encountered by humans in their daily lives, either consciously or unconsciously. Soil is defined as ‘a material, which can be more or less friable and loose, in which the plant can obtain nourishment, foothold and other essential growth factors by means of their roots’ [1]. Soil is categorized as trace evidence in forensic science. The earliest wr...
