“…The dried samples were ground to 1 mm and used for nutrient analyses following digestion of 200 mg of plant material by H2SO4/H2O2 (Bremner, 1965). N concentration was determined according to the Kjeldahl method, while P concentration was determined with the molybdenum blue method using a Perkin Elmer Lambda 25 spectrophotometer (Giannini et al, 2015). At the peak of the cover crop's growth, one 1×1 m wide destructive sample was taken from each experimental plot to evaluate the above ground biomass and the nutrient content of the cover crop and weed plants.…”

The risks of soil erosion and nutrient leaching can be considered appreciable in short rotation coppices especially in the first growth phases because of the absence of any plant cover. The temporary intercropping with legumes or grasses used as cover crops can help to overcome these environmental issues. The present research work aims to evaluate the effects of the introduction of cover crops in a short rotation poplar (Populus deltoides W. Bartram ex Marshall) with two-year harvest cycle. The plantation was located in a Typic Xerofluvent, silty-loam soil of the coastal Central Italy. Two different species of cover crops, Trifolium subterraneum L. (TS) and Lolium perenne L. (LP), were compared along with an untreated control, colonised by spontaneous vegetation (CO). Several plant and soil parameters were evaluated: the above ground biomass and nutrient accumulation for the three different soil cover types, the nitrate and water content in two soil layers (0.00-0.30 and 0.30-0.60 m), the poplar yield and nutrient content in branches and leaves.TS returned to the soil about 70 kg ha -1 of nitrogen at the end of its biological cycle, thanks to the high N content (over 2%) and to the noticeable amount of dry matter produced (3.46 t ha -1 of dry matter). This value was considerably higher than those of the LP (23 kg ha -1 of N) or CO (10 kg ha -1 ). The different amount of nitrogen returned to the soil affected both nitrate concentration in topsoil (0.00-0.30 m) and accumulation of nitrogen in poplar organs. Concerning phosphorous, the differences among treatments were less evident and the amount of P returned to the soil ranged from 2 (CO) to 10 (TS) kg ha -1 . However, the effect of soil cover type on P uptake in poplar was still appreciable. Generally, the soil water content was slightly affected by the soil cover types. Indeed, the differences between the cover crops and the control became significant only in the shallowest soil layer and over the summer season. In the first year, LP induced a significant decrease in poplar yield (10.1 t ha -1 of dry matter) in comparison with TS (14.7 t ha -1 ) and CO (13.4 t ha -1 ), whereas in the second year there were no significant differences among treatments due to the weak regrowth of cover crops.These results show how to make it feasible a long lasting coexistence between cover crops and SRC, a clever design of agro-forestry systems is therefore needed.

“…Although every decision concerning the farming practices (machinery, fertilisation, water table level control, etc.) is important for a sustainable use of peatlands, the crop choice is crucial for the success of paludicultural system but still scarce literature is available about crop choice criteria (Giannini et al, 2015). The cultivated plant species have to satisfy several different requirements (Abel et al, 2013) and only by using a multi-adaptive approach (e.g.…”

The conventional cultivation of drained peatland causes peat oxidation, soil subsidence,\ud nutrient loss, increasing greenhouse gas emissions and biodiversity reduction. Paludiculture\ud has been identified as an alternative management strategy consisting in the cultivation of\ud biomass on wet and rewetted peatlands. This strategy can save these habitats and restore the\ud ecosystem services provided by the peatlands both on the local and global scale.\ud This paper illustrates the most important features to optimise the crop choice phase, which is\ud the crucial point for the success of paludiculture systems.\ud A multi-adaptive framework was proposed. It was based on four points that should be\ud checked to identify suitable crops for paludicultural cropping system: biological traits,\ud biomass production, attitude to cultivation and biomass quality. The main agronomic\ud implications were explored with the help of some results from a plurennial open-field\ud experimentation carried out in a paludicultural system set up in the Massaciuccoli Lake Basin\ud (Tuscany, Italy) and a complete example of the method application was provided. The tested\ud crops were Arundo donax L., Miscanthus × giganteus Greef et Deuter, Phragmites australis\ud L., Populus × canadensis Moench. and Salix alba L. The results showed a different level of\ud suitability ascribable to the different plant species proving that the proposed framework can\ud discriminate the behaviour of tested crops. Phragmites australis L.was the most suitable crop\ud whereas Populus × canadensis Moench and Miscanthus × giganteus Greef et Deuter (in the\ud case of biogas conversion) occupied the last positions in the ranking

“…A soil amendment that has the potential to increase plant mineral uptake and reduce nutrient losses in grassland systems is biochar (Giannini et al, 2015). Biochar is a product produced through pyrolysis, a process of thermal decomposition of organic materials in the absence of oxygen (Lehmann & Joseph, 2009).…”

Forages form the basal diet of herbivorous grazing livestock and play a vital role not only in their sustenance but also in the production of quality products in the form of meat and milk for human consumption globally (Gómara et al., 2020). Over the past two decades, there has been a substantial consumer demand for grass-fed beef, and this has been attributed to the improved fatty acids composition and antioxidant content of grass-fed relative to grain-fed beef (Daley et al., 2010). However, in resource-limited agroclimatic environments such as the semiarid and arid regions of the world, mineral undernourishment has been a major limitation to grazing livestock productivity (Brummer et al., 2019). This limitation to beef cattle productivity has been linked to poor soil nutrients availability or
