Must composition and nitrogen uptake in a long-term trial as affected by timing of nitrogen fertilization in a cool-climate Riesling vineyard
نویسندگان
چکیده
• The timing of N fertilization needs to consider the seasonal fluctuations in nitrogen (N) uptake. These could be summarized as followes: _ during the four weeks after budbreak : N is sourced from N stored in permanent structures, _ from 2 weeks before bloom to 4 weeks after bloom: there is a major N uptake by the roots, and _ after 4 weeks post-bloom: new peaks of N uptake happen at veraison and from harvest to leaf fall.

Nitrogen and Phosphorous Loss as Affected by Plough Direction in Rainfed Wheat Land of a Semi- Arid Region
Sloping farmlands are the major sources of soil, water and nutrient losses in arid and semi-arid regions. Information about the impacts of different tillage practices on soil erosion, nutrient loss and crop nutrient uptake on the sloping farmland of semi- arid soil is, however, limited. This study was carried out to investigate the effects of tillage direction on soil, water, nitrogen and phosp...

• Norisoprenoids are important compounds that contribute to the aroma of wines. Examples of norisoprenoids are ß-ionone and ß-damascenone , which contribute intense fruity aromas; TDN (trimethyldihydro-naphtalene), which contributes the typical kerosene, or petrol, note in wines (in high concentrations, TDN may be considered a defect); and actinidol and vitispirane , which contribute other comp...
