Effect of Composted and Vermicomposted Cotton Residues on Nutrient Contents, Ryegrass Growth and Bacterial Blight Mitigation
(2013-04-05)The use of organic residues as amendments to improve soil organic matter level and long term soil fertility is gaining importance due to their potential for improving soil health and productivity. Conversion of crop residues ... -
Shoot Cadmium Accumulation of Maize, Sunflower, Flax, and Spinach as Related to Root Physiology and Rhizosphere Effects
(2011-03-22)Plants differ widely in Cd accumulation when grown on Cd contaminated soils. This is because several soil properties interact with several plant properties. Plant factors determining the ... -
Potassium uptake efficiency mechanisms and root exudates of different crop species
(2007-05-03)Potassium uptake efficiency is the ability of plants to take up sufficient K under low soil K availability. Plant species differ in their K uptake efficiency. This study was done with the ... -
Beitrag von Ackerbohne (Vicia faba L.), Luzerne (Medicago sativa L.) und Saatwicke (Vicia sativa L.) zur Selbstregelung der N-Zufuhr in leguminosenbasierten Fruchtfolgen.
(2005-03-02)The contributions of faba bean, alfalfa and vetch as sole crops (M) and intercropped (I) with oat, orchard grass and annual ryegrass to the self-regulation of N input in legume-based cropping ... -
Effect of nitrogen fertilizer on nitrogen assimilation and seed quality of amaranth and quinoa
(2004-11-23)Amaranth and quinoa are protein-rich pseudocereals and may be used as an alternative source for non-allergenic food products. Seed composition of amaranth (Amaranthus spp.) and ... -
Untersuchungen zur Sinapinsäureestersuppression und zur Expression von Resveratrol in transgener Rapssaat (Brassica napus L.)
(2004-08-12)In the Brassicaceae family, sinapic acid esters (SAE) are important anti-nutritional compounds. They contribute to the bitter taste and adstringency of rapeseed products. A substantial ... -
Laboruntersuchungen zum langfristigen Denitrifikationspotential im oberflächennahen Grundwasser hydromorpher Mineralböden Nordwestdeutschlands
(2004-02-19)In the shallow groundwater of hydromorphic soils denitrification plays an important role for reducing nitrate and production of nitrous oxide. Depending on the presence of fossil or recent ... -
Soil N mineralization dynamics as affected by pure and mixed application of leafy material from leguminous trees used in planted fallow in Brazil
(2002-12-13)In Amazon human activities such as slashing and burning converted large areas of primary forest to intermittently used agricultural land. Thus, the fallow vegetation plays an important role ...
