The research field was at Siófok, in Hungary, which is situated in the South East side of Lake Balaton. The physical characteristic of the soil is sandy loam and loam and the peach orchard is irrigated. The detailed goals were mapping and analyzing of physical properties of the soil in water management point of view, mapping the acidity and CaCO3content of soil for precision liming, measurement of humus the element content. Sites with different physical characteristics (from sandy loam to loamy clay) could be distinguished. The reason for this is that besides the possible increase of clayminerals, the increasing rate of colloidal humus content contributes to larger soil plasticity. Statistics also proved positive and strong correlation (r=0.822) between the soil plasticity and humus content. In the case of pH, only a small part of the orchard is has to be limed, since most of the orchard has neutral pH, which is advantageous for nuts and stone fruits. It has to be mentioned, that the CaCO3 supply is also appropriate for the stone fruits. Based on the results hyperspectral imagery can be a good solution for detecting calciferous soils, although these measurements are still need validation.

Peach Orchard

The research field was at Siófok, in Hungary, which is situated in the South East side of Lake Balaton. The physical characteristic of the soil is sandy loam and loam and the peach orchard is irrigated. Mainly Sweet Lady (early ripening), Red Heaven (medium ripening) and Weinberger (early ripening) species were installed. In order to achieve the optimal developement level of trees and maximal yield amount and fruit diameter (Sweet Lady 60–75 mm, Red Heaven 60–70 mm, Veinberger 50–60 mm) continous water and nutrient supply is required. The irrigation modeling was set by CROPWAT 8.0 based on the climatic, crop and soil data inputs of the last 10 years. Based on the results, large amount of water is needed for optimal growth of fruit trees, particularly in the summer months, in case of active ground cover (+) and bare soil (–) as well. The irrigation requirement of a tree was found maximum 4 l/hour in certain cases. This irrigation intensity can be achieved – calculated with 12-hour operating time – by using continuous water NAAN Tif drip tube with 2 l/h flux on 3 atm pressure with 16 mm pipe diameter. If lower irrigation intensity is required irrigation can be controlled by the decreased the operation time.

Цель исследования усовершенствование способа обогащения растений чеснока селеном до уровня суточной нормы потребления путем обработки вегетирующих растений растворами селенитов натрия и калия в сочетании с поверхностно-активными веществами и диметилсульфоксидом. Исследования проведены во ВНИИО филиале ФГБНУ ФНЦО, в условиях открытого грунта в 20162018 годах, на супесчаной почве, содержание гумуса в которой составляло 3,413,44, рНKCl 6,7, степень обеспеченности питательными веществами: фосфором высокая (содержание P2O5 в слое 020 см составляло 22,7824,62 мг (по Чирикову) калием низкая, содержание К2О в слое 20 см 10,3817,88 мг (по Масловой). Для улучшения минерального питания растений осенью под основную обработку в почву вносили калий хлористый в дозе 50 г/м2, в период вегетации проводили подкормки растений: первую, в фазе начала интенсивного роста листьев аммиачной селитрой 30 г/м2, вторую, через две недели после первой сульфатом калия 50 г/м2. Погодные условия в течение периода исследований были благоприятны для выращивания чеснока. Поливы проводили по мере подсыхания верхнего слоя почвы. Исследования проведены на чесноке озимом сорта Гладиатор. Схема опытов предполагала предпосадочное замачивание зубков в течение 30 мин. и последующую двукратную обработку вегетирующих растений 0,1-ным раствором селенита натрия и калия в сочетании с поверхностно активными веществами (1) и диметилсульфоксидом (1): первый раз в фазе начала интенсивного роста листьев и второй через три недели. Установлено, что некорневая обработка растений селенитом натрия была в 2,3 раза, а селенитом калия в 5,8 раза эффективнее, чем корневая. Сделан вывод о том, что луковицы чеснока, полученные, в результате некорневой обработки растений 0,1-ным раствором селенита натрия и калия в сочетании с поверхностно активными веществами и диметилсульфоксидом содержат в 145,3169,8 раза больше селена, чем контроль, что позволяет получить зубки, содержащие селен в концентрации 6,837,98 мг/кг. Суточная норма потребления чеснока составляет примерно 10 г, средняя потребность в селене составляет от 30 до 70 мкг. Учитывая, что содержание селена в обогащенной продукции составит 68,3 79,8 мкг/10 г чеснока предложенный способ обогащения позволяет в полной мере удовлетворить суточную потребность организма человека в этом микроэлементе.The aim of investigation was to improve the method of enrichment of garlic plants with selenium to the level of daily consumption rate by treatment of vegetative plants with solutions of sodium and potassium selenites in combination with surfactants. The investigations were carried out at ARRIVG branch of FSCVG, in open ground in 20162018, on sandy loam soil with humus content of 3.413.44, pHKCl 6.7, content of phosphorus (P2O5) in the layer 020 cm was 22.7824.62 mg (Chirikov) content of potassium (K2O) 10.3817.88 mg (Maslova). To improve mineral nutrition of plants fall under the basic treatment in the soil was added potassium chloride at a dose of 50 g/m2 during the growing season were plant nutrition: first, in the early phase of intensive growth of leaves ammonium nitrate 30 g/m2, the second, two weeks after the first potassium sulphate and 50 g/m2. Weather conditions during the period of growth were favorable for growing garlic. Watering was carried out at the periods where the top layer of soil was dried. Studies were carried out on variety Gladiator of winter garlic. The experimental design included soaking the cloves for 30 minutes before planting, and subsequent double treatment of vegetating plants with 0.1 solution of sodium and potassium selenite in combination with surfactants (1) and dimethyl sulfoxide (1): the first time in the phase of the beginning of intense leaf growth and the second time after 3 weeks. As a result of the investigations it was found that non-root treatment of plants with solutions containing selenium was more effective than root treatment. Non-root top dressing with sodium selenite was in 2.3 times, and potassium selenite in 5.8 times more effective than root. It is concluded that garlic bulbs obtained as a result of non-root treatment of plants with 0.1 solution of sodium and potassium Selenite in combination with surfactants and dimethylsulfoxide contain 145.3169.8 times more selenium than control, which allows to obtain teeth containing selenium in a concentration of 6.837.98 mg/kg. The daily consumption rate of garlic is approximately 10 g, the average need for selenium element is from 30 to 70 micrograms. Because of content of selenium in enriched products consisted of 68.3-79.8 mcg/10 g of garlic, the proposed method of enrichment allows to fully satisfy the daily need of the human body at this microelement.

This paper presents a radioecological assessment of forage agricultural land in the southwestern districts of the Bryansk region based on data characterizing the variability of the radionuclides content in the soil. Concentration of 137Cs in forage was calculated taking into account the proba-bility distributions of 137Cs soil contamination density and the soil to plant transfer factor. The pro-cessing data of the radioecological survey has shown the soil contamination density with 137Cs of agricultural lands in the southwestern areas of the Bryansk region obeys a lognormal law. The authors have used statistical models and software modules for the radioecological assessment of forage lands. Risks of exceeding the 137Cs content standards in forage obtained on soils with different texture have been calculated. The limiting levels of contamination of pastures and hay-fields with 137Cs, ensuring compliance with the specified risks for forage, have been estimated. The lowest limiting soil contamination density is characteristic of organic soils, which can be con-sidered “critical” from the point of view of 137Cs intake into forage. The authors have predicted the time of remediation of forage lands in the southwestern districts of the Bryansk region in the ab-sence of protective measures based on a probabilistic approach. The time period during which the risk of forage contamination for sandy, sandy loam and clay loam soils will decrease to 10% varies for the areas under consideration in a wide range, not exceeding 64 years. It is concluded that it is advisable to substantiate the value of the acceptable risk of forage contamination, taking into account radiological and socio-economic aspects.

Clinical trial consent for protocols and their revisions should be transparent for patients and traceable for stakeholders. Our goal is to implement a process allowing the collection of patients’ informed consent, which is bound to protocol revisions, storing and tracking the consent in a secure, unfalsifiable and publicly verifiable way, and enabling the sharing of this information in real time. For that, we will built a consent workflow using a rising technology called Blockchain. This is a distributed technology that brings a built-in layer of transparency and traceability. Additionally, it removes the need for third parties, and gives participative control to the peer-to-peer users. From a more general and prospective point of view, we believe Blockchain technology brings a paradigmatical shift to the entire clinical research field. We designed a Proof-of-Concept protocol consisting of time-stamping each step of the patient’s consent collection using Blockchain; thus archiving and historicising the consent through cryptographic validation in a securely unfalsifiable and transparent way. For each revision of the protocol, consent was sought again. We obtained a single document, in a standard open format, that accounted for the whole consent collection process: timestamped consent status with regards to each version of the protocol. This document cannot be corrupted, and can be checked on any dedicated public website. It should be considered as a robust proof of data. In the future, we think that the complex data flow of a clinical trial can be tracked using Blockchain. Moreover, a blockchain core functionality, named Smart Contract, can help prevent clinical trial events not to happen in the right chronological order: including patients before they consented or analysing case report forms data before freezing the database. This will help reaching reliability, security, and transparency, and could be a consistent step towards reproducibility.

The results of studying the elements of the technology of cultivation of a new variety of winter rye Sudarushka are presented. The research took place in 2019, 2020 in the sub-taiga zone of the Tomsk region. The impact of soil cultivation methods as well as the impact of humic fertiliser from peat Gumostim on the yield of winter rye Sudarushka is evaluated. The soils of the experimental plot are acidic (pH 4.3) soddy-podzolic loamy sandy loam. The arable horizon has a low humus content (1.5%), a low (0.2 mg/100g) content of nitrate nitrogen, a medium content of mobile phosphorus (19.2) and exchangeable potassium (7.1) and a high (11.0 mg/100g) content of mobile aluminium. The scheme of the experiment included four variants of cultivation: ploughing of fallow lands with PlN-4-35 + cultivation KPN-4,2, sowing without packing and with packing; disking with BDMK-2,8 + cultivation KPN-4,2, sowing without packing and with packing. Treatment with humic fertilizer from peat Gumostim at a concentration of 0.001% was carried out during the growing season in the beginning phase of the leaf-tube formation. The average yield of winter rye in the variety Sudarushka during the years of research was 4.66 t/ha in the variant with disking, subsequent cultivation before sowing and further sowing with packing, which is 0.34 t/ha higher than with the traditional method of soil cultivation. The application of humic fertilizer from peat Gumostim on cold sod-podzolic soils enabled the average yield of winter rye to be 4.31 t/ha y, which is 0.39 t/ha higher than without the fertilizer.
