2	Early Stages Of Calcareous Soil Reclamation Along The TMX-Anchor Loop Pipeline In Jasper National Park Cartier, Sarah B. 11 1900 (has links) Research assessed early stages of calcareous soil reclamation along the TMX-Anchor Loop pipeline through Jasper National Park. Calcareous soils are low in nutrients and highly prone to erosion after disturbances. Four sites were established in each of five calcareous soils, and divided into three pipeline right-of-way areas; work, trench and spoil. Ten amendment treatments, established within each right-of-way areaincluded a control and combinations of wood chips, fertilizer and compost with some plots having amendments incorporated. Wood chip treatments decreased availability of soil nutrients, with small plants contributing to high vegetation densities and low cover. Compost treatments increased soil nutrients and aided large plant establishment, creating lower plant densities and higher cover. Light application rates were most successful, with higher native plant densities and cover in relation to heavy application rates, which encouraged robust non-native plants. Pipeline right-of-way areas had no overall impact on early reclamation success. / Land Reclamation and Remediation Calcareous soil Pipeline Reclamation TMX-Anchor Loop
3	Potassium and Sodium Interrelations in Alfalfa Phenotypes Grown on Calcareous Soil Dhumal, Suresh S. 01 May 1991 (has links) Three greenhouse experiments were conducted with three phenotypes of alfalfa (Medicago sativa L.) obtained from a potassium (K)-deficient field and with their diallel crosses grown on low K soil. The first experiment was conduc ted to study the partitioning and broad-sense heritability of K a nd sodium (Na) between leaves and stems of the three phenotypes which were deficient in K and exhibited normal (N), marginal chlorotic (M), and white spot chlorotic (W) leaflets. The second experiment was conducted to study the partitioning of K and Na in leaves, stems, and roots as influenced by 32 alfalfa crosses obtained from diallel crossing of the mother plants of the three phenotypes. The objectives of the third experiment were to study the effects and interactions of nine alfalfa crosses and three soil K and Na levels on transpiration, biomass, and elemental composition of alfalfa components. The three phenotypes showed no variations in their leaf and stem K concentrations but varied in their ability to partition Na between the leaves and stems. Phenotype M accumulated more Na compared to N and W phenotypes. The Na trait was highly heritable in the broad sense. The K and Na concentrations varied among the diallel crosses. Crosses with M as the maternal parent had high Na concentrations in leaves while stems and roots accumulated lesser amounts. In contrast, the remaining crosses had higher Na concentrations in roots and lower and least amounts in stems and leaves, respectively. Significant genetic variation among alfalfa crosses from a single cultivar was observed for transpiration, biomass production, plant water-use efficiency, elemental concentrations, and K utilization efficiency. Leaf and stem biomass and K concentrations in alfalfa components increased in response to increasing soil K levels. The Na concentrations in stems and roots fell in response to increasing soil K levels and increased in response to Na application. The K utilization efficiency of alfalfa increased with increase in soil Na levels, indicating partial Na substitution for K. The differences among alfalfa phenotypes and crosses from a single cultivar in their Na accumulation and translocation were thought to be governed by plant genetics rather than the direct effect of K availability.

4	Phosphorus Rate Effects With and Without AVAIL® on Dryland Winter Wheat in an Eroded Calcareous Soil Hodges, Ryan C. 01 May 2019 (has links) Soluble phosphorus fertilizer is bound in the soil rapidly after application in soils high in calcium. A fertilizer additive known as AVAIL® (J.R. Simplot Company) is purported to keep applied phosphorus fertilizer more available to plants by binding to soil minerals such as calcium, magnesium, and iron, thereby reducing phosphorus binding. This could prove useful due to the attraction of AVAIL® with cations such as Ca2+, but is fairly unstudied for dryland wheat production on alkaline, calcium-rich soils. The objective of this study is to evaluate the effect of low-rate fertilizer treatments with AVAIL® on dryland small grain yield on calcium-rich, eroded hillslopes in a fallow-wheat crop rotation. Two experiments were conducted to determine treatment effects on yield and grain quality for (1) above-ground dispersed (broadcast) application of monoammonium phosphate (MAP; 52% P2O5 content) fertilizer in the spring (2017), and (2) fall application of MAP incorporated with the seed (banded) at planting (2018). Fertilizer treatments were the recommended rate (60 lbs/ac) or one-half the recommended rate (30 lbs/ac) for dryland small grain, with or without AVAIL® (four treatments), replicated four times in a strip-block design for the 2017 experiment and replicated 3 times in a randomized complete block design for the 2018 experiment. Experimental blocks were assigned to hillslope erosional severity groups. The erosional severity groups were v designated (non-eroded, slightly eroded, highly eroded, and depositional slope segments). Hillslope segmentation allowed for correlations between calcium carbonate, organic matter, and yield levels across treatments. Results from the broadcast study indicate that there was no yield advantage of any treatment at any level of erosional severity, saving a grower $20.30/acre by applying 30 lbs/acre of MAP. However, 30 lbs/acre of MAP with AVAIL® showed similar yield to 60 lbs/acre of MAP without AVAIL®, potentially saving a grower $6.42/acre over standard growing practices. The incorporated study also indicated that there was no reliable yield advantage of any fertilizer treatment at any level of erosional severity, saving a grower $15.37/acre by applying 30 lbs/acre of MAP. Neither treatment with AVAIL had greater yield or profit than those without AVAIL. Profit for the 60 lbs/acre of MAP treatment narrowly outperformed 30 lbs/acre of MAP by $1.73/acre, indicating that growers may be able to reduce phosphorus use under dryland growing conditions with optimal fertilizer placement.

5	Pyritic Lignite as a source of iron for soybean as influenced by variety and soil pH. Elvir Flores, Andrea Paola 07 August 2020 (has links) Iron deficiency chlorosis (IDC) is a frequent problem in soybean [Glycine max (L.) Merr.] production on calcareous soils. Greenhouse and soil incubation experiments were established to evaluate pyritic lignite efficacy to supply Fe as compared to Fe-EDDHA and Fe-EDTA sources across contrasting IDC tolerance varieties grown on a slightly acid and a calcareous soil. Soybean IDC incidence was influenced by the soil properties and variety tolerance. All iron sources increased plant dry matter accumulation on the Leeper soil, whereas on the Marietta soil only lignite at 0.672 kg ha-1 produced an increase. Lignite at 0.336 kg ha-1 successfully improved Fe availability to the plant as reflected by an increase in Fe content. Furthermore, no differences were found between the low rate of lignite and the commercial fertilizers on any of the evaluated parameters. Results from this study indicate that pyritic lignite may serve as an acceptable source of Fe on problem soils to prevent IDC.

6	The effects of P fertilizer addition on P transformations on high-P fixing and grassland soils Pierzynski, Joy January 1900 (has links) Doctor of Philosophy / Department of Agronomy / Ganga M. Hettiarachchi / Although phosphorus (P) is an essential nutrient for the growth of plants, it is one of the most limiting nutrients in terms of availability as a high proportion of applied P rapidly transforms into insoluble forms with low solubility in soils. To further understand the fate of P applied to soils, two separate but related studies using three high P-fixing soil types each were used for which the objectives were to investigate the mobility, availability, and reaction products from two granular and one liquid P fertilizer alone or plus a fertilizer enhancement product. Energy dispersive spectroscopy showed a substantial amount of P remained in the granule following a 5-week incubation. At the end of the 35-day incubation period there was evidence that the fluid fertilizer was superior over the granular sources in terms of enhanced diffusion and extractability of P for three calcareous soils with varying levels of CaCO₃. Phosphorus x-ray absorption near-edge structure (XANES) spectroscopy results in conjunction with resin-extractable P indicated a strong negative correlation between Ca-P solids formed and P extractability, suggesting that degree of Ca-P formation limits P solubility. For the three acidic P-fixing soils the results were complex. In two out of three acid soils, liquid P treatments diffused farther from the application point than the granular treatments. Phosphorus XANES results suggested that Fe-P or Al-P interactions control the overall P solubility. Integration of pH, resin extractable-P and XANES results suggested the P retention mechanism was either dominated by adsorption or precipitation depending on soil pH. More acidic soil conditions favored precipitation. The objectives of the third study were to observe how long-term (14 years) addition of P with or without N influences the inorganic and organic P pools in a native grassland soil using sequential fractionation, XANES, and ³¹P-nuclear magnetic resonance (NMR) spectroscopy. The overall results suggested that P and N fertilization and associated changes in plant productivity induced significant changes in soil P pools such as Ca-P, phytic acid, monoesters, and residual forms of P. The addition of P alone induced formation of inorganic P forms while the addition of P and N induced transformation of residual P forms into more labile and/or organic P forms.

7	Use Of Waste Pyrite From Mineral Processing Plants In Soil Remediation Aydin, Gulsen 01 November 2011 (has links) (PDF) Pyrite (FeS2) is commonly present in complex sulphide ores in significant amounts. After the enrichment of such ores by flotation, pyrite is either produced as a separate concentrate and sold to acid manufactures or removed and disposed off as tailing. Due to lack of demand from manufacturers, most of pyrites is usually disposed off as tailing. Therefore, pyrite is usually a waste from complex sulphide ores. Yet, it may be a remediation additive for calcareous soils and calcareous- alkali soils deficient in Fe and other micronutrients such as Cu, Zn and Mn. Waste pyrite may be also an alternative amendment to gypsum because of the production of sulphuric acid which is effectively used in the reclamation of calcareous alkali soils. The effectiveness of adding waste pyrite and sulphuric acid produced from waste pyrite to calcareous-alkali soil (Sarayk&ouml / y-Ankara) and calcareous soil (Gaziantep) was studied under laboratory conditions. Pure gypsum was also used as an amendment for the comparison of the effectiveness of waste pyrite in the reclamation of alkali soils. Gypsum, powder waste pyrite and sulphuric acid were applied to the soil with reference to the gypsum requirement (GR) of the soils. Greenhouse pot tests were carried out with wheat as test plant to determine the effect of waste pyrite treatment on the plant yield (wheat) and on the amount of micronutrient (Fe, Cu, Zn, Mn) essential for plant growth. Hazard potential of pyritic tailings in terms of heavy metal contamination was also taken into account. The results showed that the soil pH and exchangeable sodium percentage (ESP), indicators of alkalization, decreased upon pyrite addition to calcareous- alkali soils of Sarayk&ouml / y-Ankara. It was also found that pyritic tailings were effective in the increasing level of essential micronutrients (Fe, Cu, Zn and Mn) for plant growth in both soils. This was ascertained by the dry matter yield of the plants in the green house pot tests. Heavy metal toxicity caused by pyrite which is a rightful concern remained well below the legal limits in the soils. Thus, it was concluded that the application of pyritic tailings promoted rapid amelioration of calcareous-alkali soil (Sarayk&ouml / y-Ankara) and calcareous soil (Gaziantep) with no deleterious heavy metal contamination.
