“…The averaged data showed that the highest increase in nitrogen content was found in the MC and MM plots, because Persian clover and white mustard grew the largest fresh biomass [35]. Moreover, Fabaceae catch crops contain a high amount of nitrogen and quickly decompose in the soil [21]. Similar to our experiment, Marinari et al [40] noted that mulching with white mustard was effective for accumulating nutrient nitrogen.…”

“…Similarly, Liu et al [43] established that catch crops effectively increased the proportion of phosphorus in the soil. Furthermore, Wanic et al [21] pointed that the content of available phosphorus in the soil depended on the species of catch, the rate of mineralization and the P cycle.…”

“…Substances solubilize soil phosphorus and make it more available for crops. In this process, symbiotic mycorrhizal fungi play an important role [21]. Similarly, Deguchi et al [22] showed that white clover living mulch enriched arbuscular mycorrhizal colonization and increased phosphorus uptake.…”

The Impact of Intercropping on Soil Fertility and Sugar Beet Productivity

There is a lack of research on the practice of intercropping sugar beet and the impact of such agrocenoses on soil and crop fertility, especially under organic farming conditions. For this reason, a three-year stationary field experiment was performed at Vytautas Magnus University, Agriculture Academy, Lithuania. Sugar beet was grown continuously with intercropped Persian clover (Trifolium resupinatum L., MC), white mustard (Sinapis alba L., MM) and spring barley (Hordeum vulgare L., MB) as a living mulch. Inter-row loosening (CT) and mulching with ambient weeds (MW) were used as comparative treatments. The results showed that, under minimal fertilization, CT and intercropping increased the average content of nitrogen, phosphorus and potassium in the soil. However, the average content of magnesium was reduced in single cases (MW, MB), and the average content of sulphur was reduced in all cases. Intercropping significantly decreased the yields of sugar beet root-crop, but was mainly neutral in quality terms. The meteorological conditions during experimentation had a weak impact on root-crop quantity and quality. Generally, the practice of sugar beet intercropping requires more detailed research on how to minimize the competition between the sugar beet, living mulch and weeds, and how to balance the nutrition conditions.

“…Biomass production potential can be a critical determinant of cover crop selection because many ecosystem services provided, such as organic matter addition and nutrient loss reduction, are enhanced by greater biomass growth (Wanic, Zuk‐Golaszewska, & Orzech, ). Therefore, maximizing biomass production has become a major goal when growing cover crops, and much research has focused on biomass production.…”

Winter cover crops effects on soil properties and sweet corn yield in semi‐arid irrigated systems

2020

Winter cover crops (WCCs) can bolster agroecosystem services, including improving soil and crop yields. However, information is lacking about WCCs in irrigated crops in the semiarid climates of the southwestern United States. We chose three WCC species for their ecological attributes: hairy vetch (Vicia villosa, nitrogen fixation), rye (Secale cereale, nutrient sequestration; allelopathy), and mustard (Brassica juncea, biofumigant). Crops were planted in either monoculture or 2‐ and 3‐way combinations to evaluate agroecosystem services. Sweet corn (Zea mays L.) was planted approximately 2 wk after WCC termination. Neither monocultures nor mixtures consistently produced the most biomass, as WCC biomass production differed between site and year. The highest yielding cover crop was vetch (4302 kg ha−1) followed by mustard–vetch (3528 kg ha−1) and rye–vetch (3130 kg ha−1), all within the same site year, and rye (3016 kg ha−1) in another site year. Cover crops generally increased mean weight diameter of soil aggregates (a measure of dry soil aggregation) over time, with values nearly doubling in mustard–vetch and mustard–rye–vetch plots at one site. Wet aggregate stability increased by as much as 18% in mustard and 27% in mustard–vetch plots. Fertilizer requirements decreased compared to fallow plots in the second year in all WCC plots except for rye at one site, and vetch increased sweet corn yield compared to dry fallow plots in 1 yr by an average of 43.1%. These results demonstrate that WCCs can have positive effects on dry aggregate stability and potentially cash crop yield in irrigated, semiarid agroecosystems.

“…It can mobilize nutrients like potassium or phosphorus, can reduce weed density by competing with weeds, and can increase the yield of following main crops by providing nutrients from their biomass (e.g. Rinnofner et al 2008;Bodner et al 2010;Wanic et al 2018). Freeze-killed cover crops have a possible risk to support nitrate leaching, when the nitrogen saved in the biomass is mineralised in autumn and during winter.…”

Winter-hardy vs. freeze-killed cover crop mixtures before maize in an organic farming system with reduced soil cultivation

2020

The advantages and disadvantages of a winter-hardy vs. a freeze-killed cover crop mixture combined with reduced soil cultivation to a following maize crop were studied on an organic farm in Lower Austria in two consecutive experiments. Effects on soil inorganic nitrogen contents, weed density and the yield of a following maize crop were assessed. The winter-hardy compared with freeze-killed cover crop mixture, both consisting of legumes and non-legumes, reduced soil inorganic nitrogen contents over winter, leading to a reduced nitrate leaching risk, whereas the yield of a following grain maize crop was not significantly affected. Weed density was high in both cover crop treatments, presumably due to the continued reduced, noninverting soil cultivation on the farm, and higher in the winter-hardy cover crop treatment at one of the assessment dates. Combined with an adapted soil cultivation, both the winter-hardy and the freeze-killed cover crop mixture were suitable before grain maize in this organic farming system with non-inverting soil cultivation under moderately dry site conditions, but the winter-hardy cover crop mixture seems advantageous because it reduces the nitrate leaching risk.
