From different zones of Golestan province, 61 soil samples from 0-30 centimeter depth with a wide range of physicochemical properties, were obtained. In figure 1, the sample sites are shown with different symbols each of which will be explained below. The violet thin film shown in figure 1 is the pathway of sample site. Vegetation cover type of Tuskestan, Shah-koh Shah-roud regions were varied including jungle, arable land and pasture. This district was named as Site A. The B site comprised Ramian

that I would take to assess the land’s condition is to take the time and goview the property for myself. I would inspect the area for soil erosion which would be clearlyevident from the large gullies. Soil erosion makes it difficult for vegetation to regrow, a problemthat perpetuates the lack of cover and gives rise to more erosion (Withgott & Laposata, 2014).Soil erosion is a serious problem and this would need to be fixed to help prevent it fromhappening even more. Then I would look to see if the

and slope gradient influence the soil properties. This is a topic of great interest amongst geographers and Geologists alike, as slight changes within soil structures, characterisation, and soil composition will alter the soil system and its stability. The study of Relief in regards to soils is key in soil study as it will have the most outstanding impact on changes in landscapes and may potentially have detrimental impacts in societies; from an economic view of soil fertility and crop harvesting,

Effect of heat on the transport and removal of contaminants from soil 1. Introduction 1.1 Background Soil remediation has emerged as an important field in Applied Sciences due to its potential in environmental clean-up of harmful chemicals and contaminants. Various incidents in the past like the deep water horizon oil spill in the Gulf of Mexico has raised an alarming question regarding how to protect the environments encountering such devastating effects and restore them to their original state

Soil respiration is the greatest terrestrial contributor of carbon dioxide to the atmosphere and can be a direct indication of agricultural crop and soil health (Schlesinger and Andrews, 2000). The amount of carbon dioxide generated from soil respiration is influenced by several factors including, temperature, moisture, and carbon/nitrogen ratios in plant litter amongst others (Biology 208 Lab Manual 2016). The occurrence of soil respiration is as a result of root respiration which signifying healthy

has long been used as a management tool all over the world. In our study we designed 2 experiments to investigate the affect fire has on both organic soil layers and Pinus palustris (Longleaf pine) saplings. For this study, a sapling is a youth Longleaf pine less than 2m in height in addiction to one you can wrap your fingers around. The organic soil layer is made of undecomposed plant matter (litter). Samples were taken from 2 different forests located behind the UNCW campus. A prescribed burn

Literature Review Capacity of a soil to function in supporting important ecosystems without producing a negative interaction with the environment is referred to as soil quality (Larson and Pierce, 1991). This concept integrates physical, chemical and biological properties of the soil (Idowu et al, 2009). As there is an increased awareness regarding the impact of soil management on environmental quality and production of agriculture (Doran and Parkin, 1994), this concept of soil quality has gained increased

Effect of Organic Farming on Soil Nutrients and Structure Works Cited Missing Since the 1970s, the agribusiness and agrochemical industries have been aware of a growing problem: as the global population soars, soils around the world are becoming less suitable for farming as a result of erosion, nutrient depletion, and structural degradation. In the United States, about 60,000 farmers have abandoned the "conventional" system which relies on chemical fertilizers and pesticides, and adopted the

How does the pH level of soil affects plant growth Did you know 16 million people in the world are vegetarian? Plants need soil to live, and we need plants to live. Most soils contains clay, silt, sand, stones, rocks, boulders, humus, and peat. Soil also has a pH level. “A pH is a measure of the hydrogen ion concentration of a solution.”Different climates have different soil pH. For example, soil in desert has a very basic soil pH. The pH of something can be measured using the pH scale. If it is

Rain Forest Soils of La Selva Tropical rain forests across the globe are currently threatened by massive deforestation for logging, grazing, and cultivation (Otzen 1993). Such land-use practices alter temperature regimes (Fernandes and Sanford 1995) as well as ground, soil, and surface water, flora, fauna, and microorganisms (Otzen 1993). These changes may result in a loss of soil organic matter, a decrease in soil fertility (Garcia-Oliva et al. 1994, Tissen et al. 1994), severe soil erosion (Otzen
