Apple varieties have different response to fertilization and changes of root nutrition conditions. For 3 years, the effect of fertigation on the content of nutrients in the leaves and the yield capacity in rootstock 62-396 grafted apple cultivars: Lobo and Spartan was studied. Planting scheme is 4 x 1 m, trees were cultivated on meadow-chernozem and dark gray forest soils. The experiment on meadow-chernozem soil was carried in one of the farms of the Tambov region), and the plot on dark gray forest soil was located in the Lipetsk region. Leaf samples for analysis were taken during periods of the highest demand for the appropriate nutrients: phosphorus at the end of May, nitrogen at the end of June, and potassium in mid-August. Soil samples were taken before orchard planting and in August of the 3rd year of the study. The negative impact of drip irrigation on the content of soil nutrients was noted: the acidity increased on the meadow-chernozem soil, in both types of soil the content of available nitrogen decreased, as well as phosphorus and potassium in the upper layers of the soil. The content of the main nutrients in the leaves under fertigation depended on the variety response to fertilization, as well as on the soil type: the Lobo variety had a higher content of the studied nutrients in the leaves when fertigated on dark gray forest soil. The Spartan variety had a higher content of nutrients in leaves during fertigation on meadow-chernozem soil. Fertigation had a significant effect on increasing the yield capacity of Lobo variety on dark gray forest soil, and the yield capacity of Spartan variety on meadow-chernozem soil. | Сорта яблони по-разному реагируют на внесение удобрений и изменение условий корневого питания. В течение 3-х лет изучали влияние фертигации на содержание элементов питания в листьях и урожайность сортов яблони Лобо и Спартан, привитых на подвое 62-396. Схема посадки 4 х 1 м на лугово-черноземной и темно-серой лесной почвах. Опыт на луговато-черноземной почве проводили в условиях одного из хозяйств Тамбовской области, участок на темно-серой лесной почве был расположен в Липецкой области. Образцы листьев для проведения анализов отбирали в периоды наиболее высокой потребности соответствующих элементов питания: фосфор в конце мая, азот в конце июня, калий в середине августа. Пробы почвы отбирали перед закладкой сада и в августе 3-го года исследований. Отмечено негативное влияние капельного орошения на содержание элементов питания в почве: на луговато-черноземной почве увеличилась кислотность, в обоих типах почвы снизилось содержание доступного азота, а также фосфора и калия в верхних слоях почвы. Содержание основных элементов питания в листьях при фертигации зависело от отзывчивости сорта на внесение удобрений, а также от типа почвы: сорт Лобо имел более высокое содержание изученных элементов питания в листьях при фертигации на темной-серой лесной почве. У сорта Спартан отмечено более высокое содержание элементов питания в листьях при фертигации на луговато-черноземной почве. Фертигация оказала существенное влияние на повышение урожайности Лобо на темно-серой лесной почве, а у сорта Спартан на луговато-черноземной почве.

The article discusses the results of long-term monitoring of the yield of uneven-aged herbage at the test site in the Tver region. The study of the influence of soils and relief on the yield of grasses was carried out in 1998-2020 within a finite moraine hill on a transect, namely a field crossing the main microlandscape positions (relief elements) and elementary soil combinations of the agrolandscape. The state of crops and other parameters of vegetation and soil cover were studied on 30 systematically located plots. The results were processed by correlation and multivariate analysis of variance. Research has shown, that under the conditions of a finite moraine ridge, the maximum effect on the yield of grasses is exerted by the micro-diversity of a complex of poorly accounted factors of natural and anthropogenic genesis. It accounts for 66 to 73% of the spatio-temporal variability in hay production. The influence of relief and soil on the yield of young grasses is practically the same, 18 and 16%, respectively. The yield of grasses in the second and third years of use is less dependent on the relief (10-13%), while the proportion of its variability caused by the soil does not change, since they are characterized by a pronounced fluctuation in the proportion of legumes and cereals, as well as more developed root system. The influence of landscape components on the productivity of herbage is not constant over time, it ranges from 2 to 33%, And these fluctuations are random. It is difficult to identify elementary agroareals in the landscape on the basis of soil or relief maps in the conditions of finite moraine ridges. It is necessary to be guided by the knowledge about the nature of the adaptive responses of plants to the aggregate of a large number of factors of different genesis in different agroclimatic conditions, and to identify agroecologically similar territories (AST), areas with the same adaptive plant responses to landscape conditions. It is recommended to determine the boundaries of fields and lands based on the AST boundaries that are stable over time. | Рассматриваются результаты долговременного мониторинга урожайности разновозрастных травостоев на опытном полигоне в Тверской области. Изучение влияния почв и рельефа на урожайность трав проводили в 1998-2020 гг. в пределах конечно-моренного холма на трансекте – поле, пересекающем основные микроландшафтные позиции (элементы рельефа) и элементарные почвенные комбинации агроландшафта. Состояние культур и других параметров растительного и почвенного покрова изучали на 30 систематически расположенных делянках. Результаты обрабатывали корреляционным и многофакторным дисперсионным анализом. Установили, что в условиях конечно-моренной гряды максимальное влияние на урожайность трав оказывает микропестрота комплекса слабо учитываемых факторов природного и антропогенного генезиса. Она определяет от 66 до 73% пространственно-временной вариабельности производства сена. Влияние рельефа и почв на урожайность молодых трав практически одинаково – 18 и 16% соответственно. Урожайность трав второго и третьего годов пользования меньше зависит от рельефа (10-13%), в то время как доля ее вариабельности, обусловленная почвой, не изменяется вследствие того, что они характеризуются выраженной флуктуацией долей бобовых и злаков, а также более развитой корневой системой. Влияние компонентов ландшафта на продуктивность травостоев непостоянно во времени – она колеблется от 2 до 33%. Колебания носят случайный характер. Выделение в ландшафте элементарных агроареалов на основе почвенных или рельефных карт в условиях конечно-моренных гряд затруднительно, т.к. здесь необходимо руководствоваться знаниями о характере адаптивных реакций растений на совокупность большого количества факторов разного генезиса в различных агроклиматических условиях и выделять их агроэкологически-однотипные территории (АОТ) – ареалы с одинаковыми адаптивными реакциями растений на ландшафтные условия. На основе границ АОТ, устойчивых во времени, рекомендуется определять рубежи полей и угодий.

Описаны минимально необходимая информация и последовательность выделения агроэкологических типов земель на территории землепользования опытной станции (ОС), расположенной в лесостепи Приобья Новосибирской области. Выделены агроэкологические типы земель: первый тип (плакорные земли) представлен черноземом выщелоченным в сочетании с обыкновенным, оподзоленным и темно-серой лесной почвой, второй тип (слабоэрозионные земли) – черноземом выщелоченным в сочетании с темно-серой лесной почвой. Почвенный покров ОС в обоих типах земель представлен черноземом выщелоченным (Чв-2-2с), доля которого для первого типа составляет 75,26%, для второго – 76,26% от общей площади типов. Для первого агроэкологического типа земель характерно варьирование высот от 134 до 165 м. Рабочие участки относительно угла наклона рельефа расположены на склонах от 0 до 3 градусов. Вертикальное расчленение рельефа в среднем составляет 1,3 м, горизонтальное расчленение эрозионными формами – 0,8 км/км2. Второй тип земель характеризуется высотой над уровнем моря от 113 до 137 м, углом наклона рельефа – от 1 до 4 градусов. Вертикальное расчленение рельефа в среднем составляет 1,7 м, горизонтальное расчленение эрозионными формами – 0,9 км/км2. Типизация осуществлена с помощью сформированной цифровой модели землепользования (ЦМЗ) ОС на основе анализа географической информации, материалов дистанционного зондирования Земли и кадастровой карты. ЦМЗ состоит их следующих геоинформационных слоев: топография, почвенный покров, цифровая модель рельефа (ЦМР), рабочие участки. ЦМР включает информацию о крутизне и экспозиции склонов, вертикальном и горизонтальном расчленении. | The minimum required information and the sequence of agroecological land type allocation on the land management territory of the experimental station (ES) located in the forest-steppe of the Priob'ye region of Novosibirsk is described. Two agroecological land types are distinguished: the first type (upland lands) is represented by leached chernozem in combination with common, podzolized and dark-grey forest soils; the second type (slightly erosive lands) is represented by leached chernozem in combination with dark-grey forest soils. Soil cover of ES in both types of lands is represented by leached chernozem (Lch-2-2s), the share of which for the first type is 75.26%, for the second - 76.26% of the total area of the types. The first agroecological land type is characterized by a range of heights from 134 to 165 m. The working areas are located on the slopes between 0 and 3 degrees in relation to the terrain angle. Vertical dissection of the relief averages 1.3 m, horizontal dissection by erosion forms is 0.8 km/km2. The second type of land is characterized by an elevation of 113 to 137 meters above sea level and a slope of 1 to 4 degrees. Vertical dissection of the terrain averages 1.7 m, horizontal dissection by erosion forms 0.9 km/km2. Typification was carried out with the help of a generated Digital Land Use Model (DLM) of the ES based on the analysis of geographical information, remote sensing materials and cadastral map. The DLM consists of the following geo-information layers: topography, land cover, digital elevation model (DEM), working areas. The DEM includes information on slope steepness and exposure, vertical and horizontal dissection.

The Zayamchay basin is selected by its complex structure, various climatic conditions, rich vegetation and soil–rich rocks. This variation of soil–forming factors has led to the formation of various forms of soil cover structure within the basin. Therefore, the study of land and its space manifestation — the soil cover structure, detail mapping, evaluation and optimization — both scientifically–theoretical and practical. The Zeyamchay basin, which is located on the north–western slope of the Lesser Caucasus, is the object of the research. The Zeyamchay basin is selected by its complex relief structure, various climatic conditions, rich vegetation and soil–rich rocks. The area of the basin is 94200 hectares. The basin covers part of Tovuz, Shamkir and Gadabay districts from the administrative point of view. These kind of soil–forming factors have led to the formation of different forms of soil cover structure within the basin. During the research, empirical information is collected from cartographic, soil research, aerospace, landscape and geomorphological methods and so on was used.
