Soil pH is a foundational element of agronomy, profoundly influencing biological, chemical and physical soil processes. Adjusting soil pH is a paramount factor for enhancing soil health and productivity with far-reaching environmental benefits. Over time soil naturally tends towards acidity, a process expedited by intensive agriculture practices. To determine the extent of necessary pH corrections, precise soil pH testing is imperative. Various methods including buffer systems, titrations, lime incubations and algorithms considering soil texture are used to assess a soil's lime requirement and each method carries distinct advantages and disadvantages. The Shoemaker–McLean–Pratt (SMP) buffer method is extensively used in Ireland …

This lesson on soil pH explores the crucial role of soil acidity or alkalinity in plant health and productivity. Soil pH, or potential of Hydrogen ions in soil, is a measure of how acidic or basic soil is. Appropriate soil pH condition is important to grow plants. If soil pH is not appropriate, plants cannot absorb nutrients from soil well, then plants cannot grow well and cannot produce vegetables. This class will show what an appropriate soil pH condition is and how to measure soil pH of garden using simple test kit. Covering the pH scale from acidic to alkaline, …

In semiarid soils of the Western U.S., altering soil pH is not easily accomplished nor straightforward. Utah’s soil pH range can be 1,000 times more acidic or alkaline than neutral (7.0) pH soils. In semiarid regions, typical high-pH soils are also calcareous, meaning there is a large amount of solid calcium carbonate (lime) in the soil. When soil-acidifying amendments are added to these soils, the lime dissolves and counteracts any of the applied soil-acidifying amendments. This fact sheet explains how to identify whether crop symptoms are related to soil pH, how to perform an in-field test for soil pH buffering …
Lethal And Sublethal Effects Of Beauveria Bassiana On Maine Ticks Across Soil Ph, Alexander Mahar
Lethal And Sublethal Effects Of Beauveria Bassiana On Maine Ticks Across Soil Ph, Alexander Mahar
Honors College
Ticks are obligate parasite arthropods that are becoming increasingly common in northern regions of the United States. Ticks such as the black-legged tick (Ixodes scapularis) and the American dog tick (Dermacentor variabilis) are vectors for pathogens that cause a wide range of diseases, and as these ticks increase their exposure to humans, the diseases they transmit become more prevalent. This upward trend in cases of tick-borne illnesses has necessitated the pursuit of tick control methods that can be used across the diverse environments that are present in tick habitat ranges. One such control method is the fungal biological control, Beauveria …
Changes And Relationships Of Soil Aluminum, Organic Matter, And Hydrogen Ion Concentration With Rye Cover Crop, Arron Wilder
Changes And Relationships Of Soil Aluminum, Organic Matter, And Hydrogen Ion Concentration With Rye Cover Crop, Arron Wilder
Cal Poly Humboldt theses and projects
Soil acidity is a common agricultural problem worldwide, as approximately 50% of all potentially arable soils are affected by pH limitations. At soil pH 3+) is considered to be the chemical form of aluminum in acid soil that hinders plant growth the most. Potentially, soil organic matter (SOM) can ameliorate the toxic effects of Al3+ on plants and microbes by binding with Al3+, thus preventing Al3+ (and other species of aluminum) from interacting in the rhizosphere. Increasing SOM also increases soil health indicators (i.e., microbial activity, soil water holding capacity, aggregate stability, porosity, etc.) while the …

Lowland heath is of high conservation value because of the specialised and rare assemblages of plants and animals that it supports. Combinations of agricultural and urban development, and lack of appropriate management have resulted in large-scale loss and fragmentation of this habitat throughout the UK. Current UK conservation policies seek to re-create 6,000 ha of this habitat on land previously in agricultural and forestry production. Previous research indicated that high soil pH and fertility, together with a lack of propagules of heathland species, made it difficult to achieve this objective. The aim was to evaluate techniques to establish grass-Calluna …

Weeds have a significant impact on agricultural systems. They not only cause a loss in crop yield by competing with them for resources, but they can also serve hosts for several pests and parasties such as plant parasitic nematodes casusing additional crop loss. The aim of this study was to analyze plant-nematode feedback in two major weeds, Amaranthus palmeri S Watson and Parthenium hysterophorus L. First, a field survey was conducted to determine the rhizosphere nematode trophic groups associated with these two plants in the summer of 2020 and 2021. Then a 6-week greenhouse study was conducted where the two …

Comparison Of Mehlich-3 And Dtpa Soil Tests For Analysis Of Micronutrients In Kansas Soils, B. Rutter, D. A. Ruiz Diaz, L. Hargrave
Kansas Agricultural Experiment Station Research Reports
Mehlich-3 (M3) was designed as a multi-nutrient soil test procedure and has become common at soil testing labs across the U.S. In Kansas, Mehlich-3 is predominately used as a soil test for phosphorus (P) and potassium (K), but recent studies have also investigated the use of M3 for the extraction of base cations and cation exchange capacity estimation. However, data relating M3 to traditional methods for soil micronutrient extraction remain scarce. The objective of this study was to investigate the relationship between M3 and diethylenetriamine pentaacetate (DTPA) extractable copper (Cu), iron (Fe), manganese (Mn), and zinc (Zn) across a wide …

Unprecedented nitrogen (N) inputs into terrestrial ecosystems have profoundly altered soil N cycling. Ammonia oxidizers and denitrifiers are the main producers of nitrous oxide (N2O), but it remains unclear how ammonia oxidizer and denitrifier abundances will respond to N loading and whether their responses can predict N-induced changes in soil N2O emission. By synthesizing 101 field studies worldwide, we showed that N loading significantly increased ammonia oxidizer abundance by 107% and denitrifier abundance by 45%. The increases in both ammonia oxidizer and denitrifier abundances were primarily explained by N loading form, and more specifically, organic N …

We evaluated the effects of soil acidity on seedling emergence and seedling persistence of several ecotypes of Austrodanthonia spp. collected from the Central, Southern and Monaro Tablelands of New South Wales (NSW) in southern temperate Australia. A pot experiment was conducted outdoors to identify the most promising material tolerant to soil acidity for domestication. In the experiment, 183 ecotypes and two commercial cultivars of Austrodanthonia were grown in pots at three levels of pHCa (3.9, 4.4 and 5.3). The pH treatments were achieved by adding either aluminium sulphate or lime to an acid earthy sandy loam soil collected from …

The Effect Of Soil Ph On Phosphorus Content Of Clover Pasture, David Weaver, Robert Summers, David Rogers, Peta Richards
Resource management technical reports
Testing of pasture soils from 2009 to 2018, as part of DPIRD’s Whole Farm Nutrient Mapping (WFNM) project in the coastal catchments of south-west Western Australia (WA), indicated that soil pH was so low it could be limiting plant access to nutrients. Observations by some farmers who had been involved in the soil testing were that lime application had not increased pasture production, even when pHCa (pH measured in calcium chloride) tests indicated that phosphorus (P) should become more available by increasing soil pH. Farmers also wanted to know if they needed to apply more P than soil testing …

Kansas Agricultural Experiment Station Research Reports
Lime application is a key management strategy to control the acidifying effects promoted by long-term application of nitrogen (N) fertilizers and is also a source of calcium for the crops. Two field studies located in Mitchell County was carried out during 3 years (2016-2018), exploring the effect of lime application in wheat (first year), corn (second year), and soybean (third year) crops. After the first year, there was an increase in wheat yield of up to 8% with lime application. For corn (second year), liming showed a yield response of up to 10%. Soybean (third year) yield response to lime …

Theses and Dissertations--Plant and Soil Sciences
Zinc deficient soils, or soils with low Zn bioavailability, are widespread, which exacerbates Zn deficiency in human as crops grown on these soils have low Zn content. Often crop yields are also compromised. Fertilizers based on soluble Zn salts often have limited efficacy in such soils. In this research, we evaluate the performance of polymer coated and bare ZnO nanoparticles (NPs) in an attempt to overcome limitations of soluble Zn salts in alkaline soils. We first synthesized 20-30 nm bare ZnO NPs with different surface chemistries to impart colloidal stability to the particles. Bare ZnO were treated in phosphate solution …

Atmospheric nitrogen (N) deposition has been shown to decrease plant species richness along regional deposition gradients in Europe and in experimental manipulations. However, the general response of species richness to N deposition across different vegetation types, soil conditions, and climates remains largely unknown even though responses may be contingent on these environmental factors. We assessed the effect of N deposition on herbaceous richness for 15,136 forest, woodland, shrubland, and grassland sites across the continental United States, to address how edaphic and climatic conditions altered vulnerability to this stressor. In our dataset, with N deposition ranging from 1 to 19 kg …

Biochar And Nitrogen Effects On Winter Wheat Growth, T. E. Zee, N. O. Nelson, G. Newdigger
Kansas Agricultural Experiment Station Research Reports
Biochar, a co-product of thermochemical bioenergy production, may be a valuable soil amendment, but little is known about its potential long-term effects on plant growth and soil fertility. In order to gain more information, this experiment was performed to see if the addition of biochar, in comparison to lime and fertilizer treatments, has the potential to return key nutrients back to the soil or increase crop yield. A field study to investigate the effects of biochar on plant growth was initiated in 2011 near St. John, KS. Treatments included biochar applied at 16.6 ton/a (biochar), lime and annual applications of …

This study was done in an effort to better understand the multifaceted issues in amphibian decline, specifically within the eastern regions of Nebraska, to determine whether or not human-induced acid rain contributed to the decline. This is a heavily important topic of research as amphibians worldwide are declining related to many issues that stem from climate change and several other environmental issues of that nature. This study looked to use acidic pH within soil from western Nebraska to determine the reactionary impacts (primarily lesions) the western tiger salamander had after being subjected to it. It was found that pH did …

Ellenberg developed a system that assigns indicator scores for habitat characteristics of individual plant species. Swamp forests are highly diverse ecological communities and include different plant species, all of which have different ecological requirements. Ellenberg's indicator values (EIVs) were calculated for soil pH and nitrogen (N) concentration in some swamp forest species in the Central Black Sea region of Turkey. In this study, the EIVs for soil pH were usually similar in the swamp forest species studied, while some differences were found with respect to EIVs for soil nitrogen concentration. Tolerance values (TVs) of all of the studied species were …

A range of flux chambers are available and have been used to measure fluxes of atmospheric gases, including NH3, with the addition of acid traps. Previous studies show acid traps can be very effective but there is a need to understand how chambers affect acid trap efficiency so measurements can be adjusted for more accurate results. In this lab study, chamber tightness, pump flow variation, and NH3 trapping efficiency of a flux chamber system were examined. Chamber leakage varied with time from 1-7%. Pumping rate between pumps was significantly different and when included in the closed chamber …

Designing A Soil Ph Monitoring Network For The Western Australian Wheatbelt, Karen Holmes, Pat Bellamy, Jim Dixon
Resource management technical reports
Natural resource managers in Western Australia require a purposely designed soil pH monitoring network to identify areas at higher risk of soil acidification and to observe changes in soil pH through time. This monitoring network, in conjunction with field experimental work and acidification modelling, will identify state and regional trends and help shape state natural resource management policy and regional extension programmes, as well as directly inform industry and land managers.
