The objective was to determine SCC at different depths in the medium term (5 and 8 years) in a semiarid vineyard with different cover crops. The field experiment was conducted on Typic Haploxerept soil with a loam texture, pH 8.2, situated in a vineyard (cv. Tempranillo) located in the La Rioja region (northeast Spain) on Miocene sandstones, siltstones, clays and marlstones. Two different soil managements were evaluated: conventional tillage (CT) and continuous cover crop of resident vegetation (RV). Soil samples were collected from four soil layers (at depths of 0-2.5, 2.5-5, 5-15, and 15-25 cm) in June 2009 and June 2012, 5 and 8 years respectively after cover crop establishment. The SCC was determined and the SCC variation with respect to tillage treatment was determined considering the percentage of soil < 2 mm a...

Also, the action of these byproducts was compared with that of conventional amendments such as quarry limestone (QL), and gypsum (QG) Both QL, and SF were found to dramatically decrease the Al3+ content of the soil solution by raising the pH and precipitating the ion as insoluble hydroxides. Both (QG), and the gypsum-based byproducts increased the content in total Al upon application of the first few percolation rates; however, a sizeable fraction of Al was in the form of ion-pairs with sulphate and fluoride ions —the latter were displaced from the soil matrix by sulphate ions from the gypsum materials in the QG case—; this decreased the concentration...

These compounds are precursors of biogenic amines, which have negative effects to wine quality and human health. The objective was to study if the effect of conventional tillage and two cover crops (barley and clover) on grapevine nitrogen status, could be relate with wine biogenic amines. During four years, soil NO3-N, nitrogen content in leaf and wine biogenic amines concentration were determined. RESULTS: Barley reduced soil NO3-N availability and clover increased it. In 2011, at bloom, nitrogen content decreased with the barley treatment in both blade and petiole. In 2012, nitrogen content, in both leaf tissues at bloom, was greater with clover than with tillage and barley treatments. Also, total biogenic amines decreased in barley respect to tillage and clover treatments. There were correlations between some individual and total biogenic amines concentration r...

Our objective was to study the short-term effects of a cover crop on the nitrate (NO3−)–nitrogen (N) availability throughout the grapevine vegetative cycle, the grapevine and cover crop N uptake, and the yield and must quality. By short-term effects we mean the first crop cycle after planting the cover crop. The experiment was set in 2009 on a cv. Tempranillo vineyard planted in a Oxyaquic Xerorthent soil. The soil had not been fertilized with N since 2000, and two types of soil management were studied: (1) conventional tillage (CT) and (2) barley (Hordeum vulgare L.) cover crop (B). Soil samples were taken in March (bud break), June (bloom), July (setting), and August (veraison) of 2009, and the extractable NO3−-N was determined. At bloom and veraison, N contents in both blade and petiole were determined. At bloom the grapevine N uptake was estimated using the aerial parts (leaves, shoots, and bunches), and for the cover crop N uptake was determined. Total yield, bunch, and shoot weight as well as must anthocyanin and polyphenol contents were determined. Soil NO3−-N availability decreased in the cover crop from June until August, with the reduction being similar to the cover crop N uptake. Also N contents in both petiole and blade decreased in the cover crop at veraison. Regarding must quality, the cover crop increased the anthocyanin content. The reduction of soil NO3−-N availability throughout the vegetative cycle of grapevine caused a reduction in both N nutritional status and grapevine vigor, and therefore cover crops could affect must quality in the first harvest after the cover crop was sown.

These compounds are precursors of biogenic amines, which have negative effects on wine quality and human health. The objective was to study whether the effect of conventional tillage and two cover crops (barley and clover) on grapevine nitrogen status could be related to wine biogenic amines. Over 4 years, soil NO3(-) -N, nitrogen content in leaf and wine biogenic amine concentration were determined. Barley reduced soil NO3(-) -N availability and clover increased it. In 2011, at bloom, nitrogen content decreased with barley treatment in both blade and petiole. In 2012, nitrogen content in both leaf tissues at bloom was greater with clover than with tillage and barley treatments. Also, total biogenic amines decreased in barley with respect to tillage and clover treatments.

The objective was to evaluate the influence of two different cover crops upon the soil availability of N, P, K, and Mg; likewise the grapevine nutritional status, vigor, yield and the must and wine quality. The experiment was carried out on a cv. Tempranillo vineyard in La Rioja (Spain) where three treatments were established: gramineous (barley) and leguminous (clover) cover crops, and conventional tillage. Both soil N-NO3- evolution and soil P, K and Mg were determined as well as the total cover crop biomass production and its N, P, K and Mg content. Leaf nutrient content was assessed, along with vine vigor and yield. Lastly, the must and wine quality was evaluated. Results show how the P, K and Mg cover crop uptake did not reduce the soil availability of those nutrients and did not influence their concentration in the grapevine. The barley cover crop reduced N soil availability from first year leading to a leaf N and vine vigor reduction in third year, as well as a polyphenol and color intensity increase in the fourth year. In the barley treatment, those increases were statistically less significant in the wine than in the must. The clover treatment increased the soil N availability in second, third and fourth year but only resulted in an increased leaf N content in third and fourth year. Finally, barley cover crop could be a viable alternative to reduce the soil N and improve must and wine quality; although its effects were delayed from the cover crop introduction.

The areas studied included a cork oak grove (the climax vegetation in the area), a field densely covered by Cistus ladaniferus L., a field with 55% covered by Cistus crispus L. and C. ladaniferus, a field with 10% covered by bushes of the same type as the previous one, and a field with grass and occasional Cistus bushes. All of these fields with bushes were extensively cultivated with rye (Secale cereale L.) and then abandoned 45, 35, 12, and 6 years, respectively, before the study. Finally, we selected an olive grove that had been under continuous tillage for the previous 65 years. The total organic matter content decreased, starting from the virgin soil, under cork oaks, to the most heavily degraded soil (that under olive trees), whereas the bulk density increased. The total contents of exchangeable Ca, Mg, Na, and K significantly decreased, in the same trend as organic matter. In contrast, the amount of aluminum extracted by 1N KCl, AlK, remained essentially constant or even increased with increasing soil degradation. This resulted in a markedly decreased Ca/AlK ratio in the topmost 5 cm of soil, which had a strong adverse effect on crop productivity and natural plant recovery after the soils were abandoned.
