In the development of plant communities within permanent grasslands, key environmental factors include relief, climate, soil characteristics, groundwater, and anthropogenic influence. The primary objective of this study was to identify the interdependence between the botanical composition of the plant community, plant productivity, and the main biotope characteristics. The ecological and forage value assessment of the studied ecosystem involved evaluating species requirements for the following ecological indicator...

Biomass is the first form of energy used by man at the same time with the discovery of fire, means all the products of animal and vegetable origin used in present in the production of energy. Actually, the biomass approximately half (44-65 %) of the total renewable energy sources used in the EU, and occupies a third place as a primary energy source in the world, after coal and oil. At the same time represents a sustainable alternative to reduce carbon emissions. The experimental territory is located in the middle ...

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...

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...

Dioecious Cannabis sativa L. is grown for derived products that are of industrial, food and therapeutic importance. The research aims to highlight the therapeutic potential. The study's main objective is to examine the antibacterial activity of dioecious hemp extracts on two bacterial strains. The plant material comes from 4 varieties of dioecious hemp CS (Cannabis sativa L.): CS1-Armanca, CS2- Lovrin 110, CS 3- Silvana and CS 4- Teodora. The antibacterial property of the plant biological material was tested on tw...

Renewable energy is the energy produced from renewable resources replenished naturally on a human scale from sources: sunlight, wind, rain, tides, waves, geothermal heat, etc. Renewable energy induces a negligible ecological footprint that is quite limited in the area of operation, while at the same time providing obvious ecological benefits and contributing to the sustainable development of human societies. Today in 2022, renewable energy sources are considered alternatives to fossil fuels because they contribute...

The soils potential is the result of interdependence between the characteristics of the vegetation and the natural environment, also the level of production is the result of the influence of determining factors: natural environmental factors and technological factors. The influence of biotope relief factors on the above-ground vegetation is a direct consequence of the altitudinal differentiation of climatic conditions, a vegetation layer and implicitly a rather varied and complex area soil cover. It is unanimously...

By product is broadly understood as a product obtained in a usually industrial or biological process in addition to the main product for which the process is carried out. The main challenge addressed to humanity as well as productive ecosystems, regardless of the form of terrestrial or aquatic substrate, is to cope with the rapid rate of growth of the planet's population. The demographic growth of the planet must be in balance with the maintenance of the environment and also with climatic shifts. By-products are o...
