The study aimed to identify the influence of the altitudinal difference on the fertility characteristics of grasslands soils and implicitly on the production and quality of plant associations intended for grazing with animals. For that, the study material was represented by the soils of the grasslands in the region of the ?ureanu Mountains, part of the Southern Carpathians of Romania. From a geographical point of view, distinct formations were identified in the studied area with altitudes between 250 m and 1800/18...

White sweet clover (Melilotus albus Medik.) is a plant species from the group of legumes, and this is why it has a capacity to fix atmospheric nitrogen on the basis of symbiosis with bacteria of the genus Rhizobium that is not available for most plants.The species is used primarily for the production of biomass and for soil remediation. Biomass of white sweet clover can be used in biogas plants. It is also one of important producers of nectar for pollinators. The aim of the experiment was to find out whether the a...

In 2021, a field experiment was conducted with white mustard (Sinapis alba L.) the seed of which is an interesting raw material in agriculture, industry and food production. Stands of tested plants were established without tillage into a freezing catch crop from the Fabaceae family within regenerative agriculture. The stand of clovers was used as a tool of bio-drilling to work the soil and as a source of nitrogen required by the subsequent crop, and the frozen biomass was applied as mulch onto the soil surface. Th...

The aim of the study was to compare variable rate (VRA) and uniform (UNI) application of mineral nitrogen fertilizers in winter wheat and to evaluate the effect on the achieved yields, nitrogen balance and nitrogen use efficiency (NUE). For these purposes, a field experiment with an area of 16.98 ha of winter wheat was established in 2022 at farm Agra Risuty s.r.o. (Czech Republic, EU). Variable nitrogen topdressing was realized twice during the vegetation period based on yield potential (YP) maps. The evaluation ...

The highly diversified structure of the vegetal carpet in permanent grasslands, made up of numerous plant species from various botanical families, also influences a strong differentiation in the consumption of nutrients by these plant species. Thus, species with high fodder value, are high consumers of nitrogen, and meadow leguminous species require higher consumption of phosphorus, calcium, and potassium. The area of permanent grasslands studied is located in the Banat Plain Romania, more precisely at the contact...

The agricultural area of the town of Sanicolau Mare is 18,836 ha, where the following types of soil were identified: aluviosols, 2,335.66 ha; chernozems, 7,553.24 ha; vertosols, 4,407.62 ha; gleysols, 94.18 ha; solonetz, 659.26 ha; and soil associations, such as aluviosols, chernozems, vertosols and solonetz, 3,786.04 ha. The town is in the low plain of the Aranca Canal. The plain is generally plane, but slightly fragmented as a result of water erosion during flooding by the River Mure? (no longer possible nowaday...

The aim of this work was to evaluate the effect of low rates (20-40 kg ha-1) of siliconcontaining organo-mineral complex (LignoCel-Si) application on potatoes "Imanta" and summer wheat -Vinjet- productivity and quality, under conditions of organic farming. The LignoCel-Si organo-mineral complex was obtained on the basis of the residues of hydrolysis lignin and sea buckthorn (Hippophae rhamnoides L.) agro-waste lignocellulosic biomass after water-ethanol extraction, and enriched with silicon (Si)- containing inorga...

The paper presents the main limiting factors of the soils in the town of Biled, Timi? county, factors that affect the production potential of the soil cover in the area. The studied territory is located in the central part of Timi? county. The following limiting factors were reported: compactness of the soil, by 8.77%; excess phreatic moisture manifested by 12.74%, soil alkalinity manifested by 1.65%; soil acidity manifested on 0.24% and the low level of humus content signaled on 0.57% of the surface. As a result ...

The first attempts to explain the phenomena of soil formation and evolution were based on one or more pedogenetic factors, which results in the fact that there are a wide range of concepts and formulations in this regard. It is also specified that in the formation of the soil cover, in addition to pedogenetic processes, some geological processes also take place, which interfere with the formation of the soil cover and which are considered pedogeological processes. A thorough analysis of the specific and combined a...

One of the main lines of research on the impact of climate change is the study of drought and its effects on agricultural production. The aim of this study is to determine the key parameter of plant expression in relation to water stress and soil hydrophysical properties, thereby more accurately determining the need for real-time soil profile water enhancement. The research was conducted from 2019 to 2021 at the Nove Zamky experimental site, with research on royal walnut (Juglans regia L.) During the study, we clo...

The village of Sag has an area of 8,664 ha, of which 8,419 ha is agricultural land. The deterioration of soil quality has negative repercussions on either one or all soil functions. From a geomorphological point of view, the territory of the village is located in the Banat- Crisana Plain, part of the Western Plain of Romania, the eastern extremity of the Tisza Plain, in the Timis-Bega interfluvium, a unit formed exclusively by the cumulative action of the Timis River. The sustainable use of the soil involves measu...

In order to reduce the impact of agricultural activity on global warming and promote sustainable land management, it is necessary to implement management practices that reduce GHG emissions from agriculture. Conventional soil tillage produces favorable conditions for the growth of seeds and plants, but it is an energy and labor-intensive method that alters the soil to an unfavorable condition, while reduced soil tillage decrease the use of energy resources, GHG emissions from the soils, and improves the soil quali...

Water erosion is one form of physical soil degradation. As a result of climate change, global warming and changes in the distribution of atmospheric precipitation are also taking place in Slovakia. In the southern, warmer regions, snowfall decreases during the winter at the expense of rain precipitation. During the winter period outside the main crop growing season, arable land is often without a vegetation cover to protect the soil structure from the action of the kinetic energy of falling rain. For this reason, ...

The paper presents the cover of soils, their characteristics and the way of use according to the fertility and favorability of the soils identified in the Remetea Mare locality in Timis county. For this, a series of analyzes and field observations were carried out as well as comparisons of the initial data taken from previous studies and researches. Soil profiles were dug, 14 soil samples were collected in a disturbed structure to determine the main physico-mechanical, chemical and water indices, after which the d...
