“…Consequently, C:N was the highest, when the temporary grasslands were settled in acidic soil. These results were unexpected, since they show the exact opposite of the humus increasing trends along the temporary grassland establishment in the continuously used arable land (Giménez et al, 2016). The C:N is indicative of the quality of the humified organic matter in the soil (Jones et al, 2009) and of the intensity of organic matter decomposition.…”

“…However, it was estimated that over the last 25 years humus content was not decreasing along the different land use with the exception of continuous arable land (the data on the organic matter humification intensity are not shown). Skuodienė et al (2017) have indicated that the C:N in the plough horizons significantly differed (p < 0.05) between the biotopes. Consequently, in the perennial grassland and silver birch stand, the C:N was much higher than in the arable land.…”

“…The content of humus varied insignificantly from 1.90-2.16% to 1.52-2.46%, respectively, in naturally acidic and in slightly acidic soils. It has been documented that SOC could buffer the soil pH changes (Skuodienė et al, 2017).…”

“…The capture of soil nutrients is completely different in perennial grasslands from that of permanently cultivated soils. Giménez et al (2016) proved that the differences rely mainly on the management practices and spatial distribution of biogeochemical compartments in soils.…”

“…Compared to the first year, in naturally acidic soil the total root mass increased by 4.0 times and in the soil with pH 5.0 -by 11.7 times. It was influenced Literature indicates that if the mineral nutrition is unfavourable, the plants develop longer roots and increase the mass of underground organs in search of nutrients (Holub et al, 2013;Skuodienė et al, 2017). The presence of roots in certain layers is not necessarily equivalent to root activity.…”

Alfalfa (Medicago spp.) plays an important role in a farming system and contributes to stabilization of the ecosystem by improving soil physical, chemical and biological properties. However, the use of alfalfa is limited due to its susceptibility to edaphic conditions. The objective of this study was to evaluate the agro-biological traits of alfalfa under different soil conditions. Field experiments were carried out in two locations with optimised management. Agro-biological traits of 46 alfalfa (Medicago sativa L. and M. varia Marth.) accessions of different geographic origin were assessed in a high productivity Endocalcari Epigleyic Cambisol. Although environmental conditions were favourable for alfalfa development and growth, the tested genotypes significantly differed in agro-biological traits: plant height of regrowth in spring and after cuts and at flowering period as well as seed yield. Cultivars from colder climate countries (Estonia, Latvia and Lithuania) were the least affected by the downy mildew. In a low productivity acidic Bathygleyic Dystric Glossic Retisol, the pH had a major influence on the distribution of the root system of alfalfa-grass mixture. During the first experimental year, in the naturally highly acidic soil (pH 3.9), where the mineral nutrition was unfavourable, alfalfa produced longer roots, their diameter and mass were larger than in the soil with a pH of 5.0. In the third year of cultivation, in the naturally highly acidic soil only 9.1% of alfalfa plants had survived. A strong correlation (r = 0.873, P < 0.01) was determined between the amount of alfalfa in the dry matter yield and soil acidity.

Alfalfa (Medicago sativa L.) as a perennial forage grass is widely adapted to favorable environmental conditions with wide range of soils including acid soils. The productivity traits of alfalfa in the soil without and with 1.8–14.7 mgAl/kg concentration of mobile Al were investigated. The study site was conducted at the Vėžaičiai Branch of the Lithuanian Research Centre for Agriculture and Forestry, 55°70 N lat., 21°49 E long. The experiment featuring 19 cultivars was established on a Balthygleyic Dystric Retisol in 2018. In 2019 and 2020, the productivity traits were evaluated: spring regrowth, plant height before flowering, stem number, seed yield, and fresh and dry matter yield. The mobile Al negatively influenced productivity traits of alfalfa in 2019 and 2020. Several cultivars of alfalfa were distinguished by tolerance to mobile Al and will be used for further selection for breeding. In 2020, the cultivar Europe from France was distinguished by spring regrowth, number of stems and fresh matter yield in the soil with mobile Al. The cultivar Ludelis from France differed by spring regrowth and height before flowering time in the soil with mobile Al in 2019–2020. The cultivar Skriveru from Latvia was the most yielding by seed yield in the soil without and with mobile Al in 2019. The Lithuanian cultivar Antanė was yielding by dry matter yield in the soil with and without mobile Al in 2019. The cultivar Žydrūnė from Lithuania was yielding by fresh and dry matter yield in the soil with and without mobile Al in 2020. This study on acid soils with and without mobile Al concentrations has revealed the differences of productivity traits under different environmental conditions of experimental years. Results of this study are important not only for Lithuania but also for the other lands of Europe where Retisol are prevails.
