“…В грунтах и воде соединений фосфора обычно содержится на порядок меньше. Следует отметить, что фосфатный метод довольно широко применяется в археологических исследованиях для решения целого спектра задач [5,6,7,8], от определения границ распространения культурного слоя до рекон-струкции состава пищи единичных древних сосудов, причем, после пролития из разбитого крупного горшка в условиях промывного водного режима на подзолах северной тайги [9]. Рассмотренные различия в составе исходных пищевых продуктов дают возможность провести дифференциацию грунта из придонной части различных сосудов по концентрации фосфатов, существующей в настоящее время.…”

“…В перспективе данные работы необходимо продолжать, используя аналогии по результатам исследований микробиологических характеристик почво-грунтов древних поселений и погребенных почв [13,14,15], и применяя выводы с фоновых объектов для сосудов. Кроме того, большие перспективы для изучения почв в древних горшках открывают работы по ферментативной организации почв [16], при условии проведения корректных экстраполяций.…”

Изучены почво-грунты из древних сосудов, погребенных под курганными насыпями лесной зоны РФ. Уникальность выборки сосудов горшечного типа в их культурной принадлежности к древнемордовской культуре и датировке ранним железным веком. С палеопочвенной точки зрения определение пищи в почвах лесной зоны проведено впервые. Установлено, что с водой сосуды практически отсутствовали, и подавляющая часть исследованных фосфатным методом почво-грунтов сосудов содержала белковый продукт.

The article describes the results and the methodology for determining the initial presence of wares containing cellulose in the Vyatichi funeral ceremony in the Middle Ages in the natural zone of the southern taiga, Moscow region. Cellulose is a high molecular weight polymer. Cellulose (in other words – fiber) contains up to half of all the organic carbon of the biosphere, therefore, the prevalence of various microorganisms utilizing cellulose is quite high. In addition, the prevalence of this trophic group of microorganisms significantly complicates the diagnosis in archaeological contexts, since it’s necessary to understand the total number of these microorganisms on different depths in certain soil types and certain climatic zones. To overcome this difficulty, we conducted a two-month experiment to determine the rates of decomposition of the added cellulose substrate by soils from the adjacent structures of cremated burials using method, providing results comparable with published data. For the first time, there was made an attempt to identify soils of cremated burials with an increased content of cellulose, by analogy to microbiological methods of identifying keratin-containing substrates of ancient burials. The presence of cellulolytic microorganisms was identified by counting of colony forming units after planting on a solid nutrient environment – soil agar enriched in carboxymethyl cellulose. The object of the experiments was soil samples from medieval burials with cremations. Comparisons were made with the background soil of the same age as cremations (XII century), which have been developing according to the zonal type on the kurgan mound nearby to cremated burials. Three sites with maxima activity were revealed, according to the archaeological context. The article continues the cycle of experimental planting of trophic groups of microorganisms for the purpose of indicating substances that entered the soil at different periods of time, from antiquity to the Middle Ages, and have been utilized by microorganisms up to nowadays.

The influence of wood biochar on the content of various forms of phosphates was studied in laboratory experiments on soils with different phosphorus availability. Soils of the middle taiga subzone of Karelia were used in this work: a sandy Umbric Podzol and a heavy loamy Umbric Retisol. The tests studied the effect of two fractions of biochar (3–5 and ≤2 mm) in an amount of 2% and 5% of soil mass on pHKCl, the content of available and total phosphorus, the inorganic phosphorus fractions (Chang-Jackson method), and the total phosphatase activity of soils, as well as the effect of separate and combined application of biochar and fertilizer (NPK) on the content of available phosphorus in a pot experiment with spring barley. The research revealed that biochar significantly increased the content of available phosphorus by 20–40%, increased the content of the fraction of Ca-bounded P, Al-bounded P and loosely-bounded P, and also increased the phosphatase activity in the Umbric Podzol. In pot experiment was noted a higher content of P2O5 in variants with biochar ≤2 mm, in variants with fertilizer, and a significant mutual influence factors of biochar and fertilizer. Biochar increased the content of available phosphorus by 2–6%, increased the content of Ca-bounded P and loosely-bounded P (with biochar ≤2 mm at 5% dosage), and had no significant effect on the phosphatase activity in the Umbric Retisol. Only combination of biochar ≤2 mm and fertilizer had a significant effect in pot experiment with Umbric Retisol. In general, the most noticeable effect on almost all studied indicators was provided by ≤2 mm fraction of biochar in a 5% dosage. The use of biochar led to statistically significant increase in pHKCl values, and did not affect the content of total phosphorus in both soils. Biochar had a greater effect on the phosphate regime of coarse-textured soil with an initially lower pH and a less content of available and total phosphorus.
