The management practices, most frequently suggested to increase soil organic carbon content have variable effects depending on pedo-climatic conditions and have to be applied for a long time periods to maintain their sink capacity. Biochar (BC), a carbon rich product obtained through carbonization of biomass, can be used for carbon sequestration by applying large amounts of carbon very resistant to decomposition. The BC remains into soil for a long time and there is evidence that the BC stores atmospheric carbon from centennial, to millennial timescales. However most of the agronomic studies on BC application have been made in tropical and sub-tropical climates, while there is a substantial lack of studies at mid-latitudes and in temperate climates. This paper presents the results on an investigation of large volume application of BC (30 and 60 t ha-1) on durum wheat in the Mediterranean climate condition, showing the viability of BC application for carbon sequestration on this crop. BC application also has positive effects up to 30% on biomass production and yield, with no differences in grain nitrogen content. Moreover no significant differences between the two BC treatments were detected, suggesting that even very high BC application rates promote plant growth and are, certainly, not detrimental. The effect of the biochar on durum wheat was sustained for two consecutive seasons when BC application was not repeated in the second year.", "keywords": ["2.

Grain and biomass yield and its components were determined at maturity and the grain metabolome was analysed by gas chromatography-mass spectrometry (GC\u2013MS). Elevated CO 2  (537  versus  409\u00a0\u03bcl\u00a0l \u22121 ) increased biomass production except for leaves. In total, levels of 16 grain metabolites were decreased and four were increased. CO 2  enrichment resulted in significant decreases of amino acids such as o-acetyl-L-homoserine, leucine, arginine, L-homoserine and the group of ornithine, arginine and citrulline and negative trends for norleucine, L-aspartate, proline, L-cysteine and tyrosine. The amines D/L-diaminopimelate and alpha-ketoaminobutyrate and the polyamine putrescine were significantly decreased. In contrast, the polyamine spermidine tended to increase under elevated CO 2 . Among sugars and sugar derivatives, ribose-5-P was significantly increased, while gluconate-6-P was decreased. There were also negative CO 2 -induced effects on sugar alcohols: significant for glycerol-2-P ( P \u00a0=\u00a00.008) and almost significant for myo-inositol-P ( P \u00a0=\u00a00.066). In contrast, organic acids such as pyruvate and glucuronic acid were significantly increased. Overall, the N-rich metabolites especially were reduced. CO 2  enrichment can markedly affect the physiology and metabolome of mature grains which may in turn lead to changes in nutritional status.", "keywords": ["0301 basic medicine", "2.

Treatments were rotary-till wheat + rotary-till rice without any straw (conventional treatment, CK), zero-till wheat with rice straw mulching + rotary-till rice with no wheat straw (WZRR), zero-till wheat with rice straw mulching + rotary-till rice with no wheat straw + autumn vegetable (WZRRV), zero-till wheat with rice straw mulching + zero-till rice with wheat straw mulching (WZRZ), and zero-till wheat with rice straw mulching + zero-till rice with wheat straw mulching under ridge-till (WRZB). There was little variation amongst years in grain yield and yield components with the treatment, while CK had lower yields in most years than other treatments with a slight decreasing trend; spike numbers per area had no significant change with the elapse of time. An obvious descending trend in grain number per spike and grains per area for CK and increase in 1000-grain weight for all treatments were observed; zero tillage and straw mulching improved wheat tiller ability, soil available nitrogen, phosphorus, and potassium contents at major growth stages, and leaf area index, SPAD, a portable chlorophyll meter reading, and dry matter at middle and late stages. Most grain quality traits of wheat were nearly the same in all treatments in all year-round tillage patterns.", "keywords": ["0106 biological sciences", "2.
