“…Hunady et al ( 2021) calculated the theoretical methane yield and revealed that the values of biomass from Galega orientalis, Lathyrus pratensis, Trigonella foenum-graecum and Melilotus alba ranged from 0.161 to 0.172 m 3 /kg VS, the methane yield of biomass from Onobrychis viciifolia, Astragalus cicer, Dorycnium germanicum, Vicia sylvatica ranged from 0.141 to 0.160 m 3 /kg VS and the absolutely lowest value -0.12-0.14 m 3 /kg VS -was calculated for Medicago sativa. Petcu et al (2022) found that in winter peas herbage C/N=9.24-12.63.…”

“…The benefits of leguminous forage plants within farming systems have long been recognized and include a higher production of meat, milk and wool by ruminants, improvement of soil fertility, root disease management in cropping systems, increasing biodiversity and risk management in diversified systems, particularly under the conditions of climate change. Many Fabaceae species have valuable medicinal properties and multi-purpose use in various industries; besides, they are excellent honey plants and cover crops (Lewis et al, 2005 al., 2013;Stoddard, 2013;Stinner, 2015;Foster et al, 2021;Petcu et al, 2022). The interest in systems based on legumes has increased significantly over the recent years due to their importance for sustainable and organic farming.…”

The efficient use of the biological potential of the leguminous plants that are adapted to the local climatic conditions becomes more and more relevant. The local ecotype of the species Lathyrus sativus, Lathyrus sylvestris, Lathyrus tuberosus, Vicia hirsuta, Vicia sativa, Vicia tenuifolia maintained in monoculture on experimental land in the NBGI Chişinău, served as objects of study. We found that the dry matter of the studied whole plants contained 169-257 g/kg CP, 96-125 g/kg ash, 219-346 g/kg CF, 244-371 g/kg ADF, 427-576 g/kg NDF, 34-58 g/kg ADL, 210-313 g/kg Cel, 183-205 g/kg HC, 64-150 g/kg TSS, with 59.3-69.4% DMD, RFV = 93-151, 11.87-13.55 MJ/kg DE, 9.75-11.13 MJ/kg ME, 5.77-7.22 MJ/kg NEl. The prepared hay contained 153-264 g/kg CP, 91-135 g/kg ash, 244-356 g/kg CF, 294-393 g/kg ADF, 475-606 g/kg NDF, 36-65 g/kg ADL, 258-329 g/kg Cel, 191-214 g/kg HC, 6-99 g/kg TSS, with 59.2-66.0% DMD, RFV = 90-129, 11.57-12.95 MJ/kg DE, 9.50-11.09 MJ/kg ME, 5.51-7.10 MJ/kg NEl. The haylage is characterized by pleasant smell and color, pH = 4.40-4.95, 4.7-6.1 g/kg acetic acid, 27.9-38.0 g/kg lactic acid, butyric acid was not detected, 159-180 g/kg CP, 105-125 g/kg ash, 296-343 g/kg CF, 316-360 g/kg ADF, 460-579 g/kg NDF, 51-55 g/kg ADL, 263-309 g/kg Cel, 142-219 g/kg HC, 43-106 g/kg TSS, 60.9-64.1% DMD, RFV = 98-129, 12.03-12.61 MJ/kg DE, 9.88-10.35 MJ/kg ME, 5.89-6.37 MJ/kg NEl. The harvested fresh mass and the haylage prepared from the studied species can be used as substrates in biogas production via anaerobic digestion for renewable energy production, with carbon nitrogen (C/N) ratios 12-20. The biochemical methane potential reached 320-378 litre/kg organic matter. The investigated leguminous species are an important forage source for livestock, many birds, bees and entomophagous insects, and they are excellent plants for erosion control and for reseeding and increasing the economic value of permanent and temporary grasslands. The harvested biomass can be used as alternative fodder for farm animals or as substrates in biogas generators for the production of renewable energy.

“…Although global warming caused by CO2 and CH4 air pollution is commonly considered unprecedented, rocks and fossils indicate similar redox atmospheric crises (Retallack, 2007). One of the most difficult aspects of balancing carbon in the atmosphere is sequestering it through photosynthesis in forests or managing carbon in farming practices such as cover crops or fertilizer use [8]. Moreover, the increase in the demand for food and food waste, which is unanimously recognized for developed countries, is considered to have led to an increase in the number of livestock and the amount of fertilizers used in agriculture, with the consequences of increasing the amount of nitrates (NO3) and ammonia (NH3), released into the atmosphere.…”

Average temperatures in Romania have risen by more than 1.5 degrees Celsius in the last thirty years, although the transition to a clean economy began with the closure of the gates of large resource-consuming and waste-generating enterprises. This fact confirms that there are enough polluting causes left in Romania that have contributed to the degradation of the environment and climate warming. In such a context, in an attempt to identify the main causes that led to the increase in average temperatures, the present study focuses on the road transportation and animal husbandry sectors assuming that pollutants and waste removed from them could justify this evolution. The forestry sector has also been taken into account, and its ability to balance and contribute to combating the undesirable effects of climate change is well known. In addition, the study aimed at analysing public policies and highlighting the measures that have been adopted at the international level that could inspire the decision makers in our country. Given all these elements, the current analysis indicates the existence of a causal link with the road transportation sector, a situation which could be partially explained by certain concerns about the public measures adopted in this regard. The study will be continued with the inclusion of other potential elements to gain an overview of the local specificities that condition the achievement of the assumed objectives.

“…Their research revealed an orientation especially towards the production of electricity from biomass and that "most energy is produced by wind turbines, plus solid biomass for heating", but the main conclusion was that after 2020 "agricultural waste will surpass first-generation energy crops as a supplier of primary energy". Other researches are focused on the implications of incorporating the biomass generated by cover crops into the soil in increasing the carbon and nitrogen content of the soil, in order to reduce the inputs used in agriculture (Petcu et al, 2022).…”

Biomass energy production is a priority for the global economy in terms of ensuring the premises for sustainable development. The current context, determined by increases in energy costs, involves the identification of applicable and eco-intensive measures by which the use of biomass in productive activities will reduce the level of pollution and, implicitly, global warming. Progress of the bioeconomy is intercorrelated with the dimension of agriculture, which is the major provider of biomass for food, feed, and other bio-based industries. The agricultural sector in the last decades is characterized by an increase in energy production and consumption, with direct consequences on the environment. Biomass is for Romania, a renewable energy source, particularly valuable, both in terms of potential and in terms of future use, through complementarity with the sustainable development programs of the state that aim to develop the capacity of production and the creation of well-being. This research aims to estimate the energy efficiency of three types of COP farms (which cultivate cereals, oilseeds, and protein crops) of different physical sizes, and the analysis of the potential energy generated by energetical cultures, with emphasis on biomass energy. The energy balance at the farm level remains a very important method to determine the efficiency of agricultural systems and for the assessment of potential energy from biomass. With this study, we emphasize the need to support a more sustainable demand for biomass and to make the bioeconomy market more competitive.
