Abstract
<\/strong>Crop rotation diversification using legumes has been advocated as one of the solutions to improve the resilience of the crop system to various environmental stresses and the use of nitrogen resources. However, when forage legumes or grass-legumes are ploughed, there is a high risk of nitrate leaching, especially in sandy soils (https:\/\/doi.org\/10.1016\/j.agee.2017.12.009). Skipping autumn tillage can reduce the decomposition of plant residues and promote soil humification processes. We hypothesized that winter wheat (Triticum aestivum<\/em> L.) \u2013 forage legume strip intercropping technologies could optimize crop residue mineralization and increase soil organic carbon. The aim of the study was to determine the effect of winter wheat \u2013 black medick (Medicago lupulina<\/em> L.) WW+BM, winter wheat \u2013 white clover (Trifolium repens<\/em> L.) WW+WC, and winter wheat \u2013 Egyptian clover (T. alexandrinum<\/em> L.) WW+EC strip tillage intercropping management on soil mobile organic carbon content compared to forage legume monocropping with conventional tillage. The study was carried out at the LAMMC Joni\u0161k\u0117lis Experimental Station on Endocalcari-Endohypogleyic Cambisol <\/em>(siltic, drainic) in 2018\u20132019 (Experiment I) and 2019\u20132020 (Experiment II). In 2018 and 2019, legumes were grown with oats (Avena sativa<\/em> L.) or in monocrops. After harvesting the oats, the straw was chopped and spread, the legume grass was mulched, and winter wheat was sown using the strip tillage system involving one-pass tillage. The legume monocrops in autumn were ploughed and winter wheat was sown. After harvesting winter wheat, soil was taken and water-extractable organic carbon (WEOC), mobile humic substances (MHS) and mobile humic acids (MHA) were determined. The results showed, that in winter wheat \u2013 forage legumes intercropping, WW grain yield decreased (especially in Experiment I), compared to the same grasses monocultures that were ploughed before WW sowing. The highest amount of WEOC was in intercropping soil WW+WC (Experiment I) or in all fields (except WW+EC) after applying strip tillage. During the research period, the amounts of MHS and MHA changed analogously (especially in Experiment I). Their content increased substantially in fields with BD and EC, regardless of whether the grasses were ploughed or grown with WW. In experiment II, these differences were smaller, and the variation in MHA content was slight. Studies have shown an inverse correlation between WW grain yield and soil mobile forms of organic carbon.<\/p>\n
