Abstract:

Improving productivity of sodic soils has become a concern in North Dakota because of the desire for more land for producing crops. Field and incubation studies were conducted to determine the impacts of different amendments (flue-gas desulfurization gypsum, sugar beet processing by-product lime, and langbeinite) on the chemical and biological properties of two sodic soils. The field study evaluated the amendment effects on the chemical conditions of the soil and the impact on alfalfa yield and quality. Differences were not observed in percent sodium (%Na) in the first 17 months and alfalfa yi

Abstract:

The results of the research showed that hydromorphous soils prevail on the territories adjoined to waste heaps. Swampy meadow and sod soils were defined. During investigation of swampy meadow soils it was determined that the soil is humused at a considerable depth. The soils are saturated with the bases. According to granulometric texture it is sandy loam soils, but with depth go to the middle loamy soils. The analysis for labile forms of heavy metals showed that in these soils the content of investigated heavy metals does not exceed the maximum allowable concentrations, except for lea

Abstract:

Forest areas are particularly susceptible to fires, which are often manmade. Too-frequent fires are likely to adversely affect the soil properties as well as vegetation composition, and possibly lead to soil erosion and desertification. One of the most fire affected forest regions in the world is the Mediterranean. Libya, in the Mediterranean region, has soils that are considered to be arid except in a small area called Aljabal Alakhdar (Green mountain), which is the geographic area covered by this study. It is the wettest part of Libya, and has an extensive forest and many agricultural crops.

Biochar can also increase soil carbon (C) inventory as a means of carbon storage and nitrogen (N) retention, improve plant growth, and reduce greenhouse gas emissions. Meanwhile, nitrous oxide (N2O) is a potent greenhouse gas with ca.

However, the remediation of old industrial sites is challenging, for several reasons.

Abstract:

Composted biosolids have been shown to enhance turfgrass establishment and growth more than fertilizer alone, but few studies have investigated the production of turfgrass using uncomposted biosolids. Increasingly employed treatment methods that generate pathogen-free, low pollutant-containing biosolids are creating alternative products for use in urban settings. Understanding the effects of these uncomposted and alternative biosolids products on turfgrass culture and soil chemical and physical properties is essential to understanding the benefits these products may provide in sod production

Entretanto, para o melhor entendimento de sua formação e ocorrência são necessários estudos de variabilidade espacial. A geoestatística é a melhor ferramenta para este estudo, sendo que a Krigagem ordinária (KO) é um interpolador de mínimos quadrados, mais utilizado em ciência do solo. Porém, ela suaviza os detalh

Abstract:

This study examines the spatial patterns of soil parameters to test the hypothesis that shrub encroachment initiates a change in scale of soil heterogeneity, which consequently influences a landscape's biotic and abiotic interactions and thus the susceptibility of soil to erosion. Grassland, shrubland and badland sites were established in two semi-arid environments; the Karoo, South Africa and the Sevilleta National Wildlife Refuge, New Mexico, U.S. 108 soil samples from each of the eleven 60m x 60m plots were analysed for bulk density, shear strength, texture, aggregate stability, organic mat

Abstract:

Bibliography: leaves 71-78.<br>It is widely accepted that afforestation adversely affects soil chemical properties. A significant decrease in pH, base cation status and acid neutralising capacity (ANC), coupled with increasing acidity have been observed to occur in acid coniferous forest soils both in the Northern and Southern Hemispheres. International and local studies in Southern Africa have observed declining productivity over successive rotations in pine plantations. Increasing acidity loads in the Northern Hemisphere and their adverse effects on forest health have generated a search for

Abstract:

Thesis (M.Sc.(Soil Science)) -- University of Limpopo, 2015<br>Winery solid waste materials namely, wine filter materials (FM), grape marc (berry stalks, skins and seeds) and chopped grapevine pruning canes were composted in heaps through a thermophilic process. The filter materials were mixed with the grape marc and grapevine prunings at five rates (10%, 25%, 50%, 75% and 100%) to produce five composts herein designated as C10FM, C25FM, C50FM, C75FM and C100FM, respectively. A laboratory incubation study was thereafter carried out to determine the nutrient release potential of the composts us
