“…However, the supply of these high-K, evaporite minerals is finite, therefore new sources are required to meet predicted demand and support food production for the increasing global population. This is a global issue because of the challenges of identifying and extracting new K deposits (Cocker et al ., 2016).…”

The response of winter barley (Hordeum vulgare) and forage maize (Zea mays) crops to polyhalite, a multi-nutrient fertilizer

Polyhalite is a multi-nutrient mineral ore containing potassium (K), calcium (Ca), magnesium (Mg) and sulphur (S). Historically, it has enjoyed minor use as a fertilizer, but the opening of a new mine in the UK will make larger quantities available. Therefore, an examination of the performance of crops fertilized with polyhalite, or selected commercial alternatives, was pertinent and is reported here. Four field trials were carried out between 2013 and 2016 to investigate the response of winter barley (Hordeum vulgare L.) and forage maize (Zea mays L.) to different application rates of polyhalite, potassium chloride (muriate of potash, MOP) and potassium sulphate (sulphate of potash, SOP) fertilizers. Potassium and S nutrition were the focus of these trials as they limit field production more often than Mg and Ca. Polyhalite was found to be an effective source of both K and S for crop production. In three out of four trials, application of polyhalite resulted in similar or greater K offtake compared with both MOP and SOP; MOP application resulted in greater K offtake in one trial. In three out of four trials, application of polyhalite resulted in similar or better S offtake compared with both MOP and SOP; SOP application resulted in greater S offtake in one trial. Polyhalite and MOP treatments produced similar total dry weight in all four trials, but were slightly inferior to SOP treatment.

“…Potassium differs from N and P. As explained clearly by Cocker et al (2016), the global demand for K is very skewed: ÔObtaining sufficient amounts of potash is a global trade issue, usually involving rail and ocean transportation over vast distances. Because potash is a bulk commodity where its end cost is governed greatly by the cost of transportation, the proximity of a nation to potash deposits and the availability of low-cost transportation determine the price that a nation will pay for fertilizer.Õ In these circumstances, the prosperous global north evidently can afford to compensate for crop offtake by application of potash derived from a global market that is dominated by two northern hemisphere source regions, Canada and Belarus-Russia (Sheldrick et al 2002).…”

“…Potassium (K) differs from P and N; at present, conventional K fertilizers are produced predominantly from mined salts (potash; Cocker et al 2016), especially sylvite (KCl) and carnallite (MgCl 2 AEKClAE6H 2 O) or brines, and require much less chemical processing to produce a fertilizer product . About 39 million tonnes of K 2 O equivalent are mined from 12 countries, with a trivial amount produced elsewhere (50,000 T; Jasinski 2016b).…”

“…Although conventional potash deposits in evaporite basins, suitable for mining economically using current technologies (Cocker et al 2016) A number of studies have investigated the possible use of silicate minerals as sources of K for crop growth, in circumstances where conventional potash is either inaccessible for geographic or economic reasons, or when salts are less suitable because of rapid removal from soils through leaching (Leonardos et al 1987). Early work focused on Norwegian nepheline syenites, at a time after World War 1 when Germany controlled potash markets (Goldschmidt 1922;Goldschmidt and Johnsen 1922).…”

Mineral resources are fundamental to the growth and development of human society. Extraction of metal ores has risen very slightly as a proportion of all resources, while construction and industrial mineral extraction has grown much more rapidly. This reflects growth in GDP, which is much faster than population growth, in turn reflecting improved standards of living, growth in urban housing/infrastructure and growth in the consumer society. Fertilizer minerals in particular are essential resources for production of the food needed by an increasing global population. Nitrogen fertilizer manufacture requires fossil fuels-especially natural gas (methane) as a source of the hydrogen needed for the HaberBosch process. Phosphate fertilizers are predominantly manufactured using phosphate rock as a source of phosphoric acid, and there is scope to recover phosphorus from contaminated waters. Potassium fertilizers are produced from evaporite deposits, mainly in the global north. It is difficult for poorer countries with deeply leached soils to access and make efficient use of existing conventional products. Globally, while N and P fertilizer application replaces the nutrient removed by crops and so is in balance, twice as much K is being removed from soils as is being replaced. This leads to the need for innovation in developing novel sources of K, especially to support agricultural production in the global south. Rocks containing K silicate minerals (such as feldspar and nepheline) occur widely as potential sources of K for use in soils where these minerals weather rapidly. Observations of surface corrosion in feldspars taken from soils after 10 years exposure to soil microbial systems demonstrates rates of dissolution 4 orders of magnitude greater than determined in the laboratory. Innovation in use of these minerals depends on an understanding of the role of microbial processes in silicate mineral decomposition.

“…Верхнекамское месторождение солей (ВКМС) является уникальным объектом, обладающим мировым значением. Как по запасам, так и по объемам добычи калийных солей ВКМС занимает второе место в мире, а история его освоения насчитывает почти 100 лет (Кудряшов, 2013;Rauche, 2015;Cocker, 2016). Этому способствует геологическое строение, которое характеризуется наличием мощных выдержанных пластов каменной и калийных солей, занимающих Соликамскую впадину.…”

Статья поступила в редакцию 11 декабря 2017 г.) Исследования гидрохимического влияния объектов калийной промышленности проведены в центральной части ВКМС, в окрестностях г. Соликамска (Пермский край). Обобщены данные мониторинга состава подземных вод на участке, планируемом к освоению, и результаты опробования родников в непосредственной близости от действующих предприятий. Результаты сопоставления усредненных характеристик химического состава показали значительные изменения в составе вод. Анализ степени этих изменений проведен с использованием статистических методов. Ионный состав подземных вод обогащается хлоридами, бромидами, катионами натрия, калия, кальция, магния, аммония. Гидрохимическими индикаторами изменения микроэлементного состава являются марганец, кобальт, мышьяк, ванадий, никель, сурьма, барий, стронций, селен. Ключевые слова: подземные воды, химический состав, месторождения калийных солей, техногенез, геохимические индикаторы.
