This study investigated the effects of soil crust development on the underlying soil properties. The field sampling work was conducted in June 2016 in the Hobq Desert in Inner Mongolia, North China. Soil crust samples and 0–6, 6–12, 12–18, 18–24, 24–30 cm deep underlying soil samples were taken from five representative areas of different soil crust development stages. All samples were analyzed ...

Biowaste, the separately collected organic fraction of municipal solid waste, can be reused for soil conditioning after composting. In this way, environmentally harmful waste management strategies, such as landfilling or incineration, can be reduced. However, frequent application of composts to soil systems may lead to the accumulation of heavy metals in soils, and therefore legal criteria were...

   Current study monitored Electerical Conductivity (EC) as soil salinity index and Organic Matter (OM) in the area of Harat in Yazd, Iran, through remote sensing technology with high spatial and spectral resolution. The images were selected from IRS, LISS III satellites between the years 2008 and 2012. After preprocessing and analyzing the images, the relationship between parameters of (EC) an...

this paper presents a method for generating a digital management map to apply cyanazine pre-emergence herbicide. the main objective was to develop a precision method to generate management maps for the variable rate application of herbicide to reduce the amount of herbicide applied and its adverse impact on the environment. first, local and utm coordinates of a field were determined using total...

A health ecosystem is the aim of building a nice Loess Plateau with green mountain and clear river. This paper, taking Zhifanggou small watershed as an example, by using the AHP (Analytic Hierarchy Process) selecting the woodland and pasture cover, area of fundamental cropland, soil anti-scourability, soil organic matter, output/input, crop yield, net incomes of per capita and benefit of reduci...

This study was conducted to investigate direct short-term impact of vermicompost on some soil biological properties by monitoring changes after addition of vermicompost as compared to farmyard manure in an alkaline soil with high lime content from semiarid Mediterranean region of Turkey. For this purpose, mixtures of soil and organic fertilizers in different doses were incubated under greenhous...

to study the effect of salinity and organic matter on chemical composition and root morphology of pistachio cv. badami, budded on seedling root stocks, a greenhouse experiment was conducted as a factorial based on a completely randomized design with three replications. treatments consisted of four salinity (zero, 800, 1600 and 2400 mg nacl kg-1 soil) and three organic matter (zero, two and four...

The Illyric–Balkan endemic species Moltkia petraea (Tratt.) Griseb. is very interesting as a potential horticultural and medicinal plant. The aim of this study was to investigate soil conditions of M. petraea habitats, the phenolic content in plant parts, and the infl uence of soil properties on the phenolic contents. The results were evaluated using Spearman rank order correlations. Analyzed s...

This research was conducted to investigate the relationships between soil(organic matter, potassium, phosphorous, sodium, fine gravel, soil texture, EC, lime,gypsum, nitrogen) and environmental (elevation, slope) factors with distribution ofvegetation types in rangelands of Sabzdasht, located in Bafgh, Yazd province at 2012. Forthis purpose, four vegetation types were selected as follows: Artem...

expansive soils may cause disaster if not adequately taken care of. lime continues to be commonly used for modification of these types of soils although it may have limited success in some applications. thus, the present study was performed to address the viability of using silica fume (sf) as industrial waste to modify the behavior of expansive soils. this achieves the double objectives of ove...
