Little Potential of Spring Wheat Genotypes as a Strategy to Reduce Nitrogen Leaching in Central Europe
Nitrogen (N) losses negatively impact groundwater quality. Spring wheat genotypes varying in N-fertilizer recovery were studied (by using lysimeters) for their potential to minimize NO3-N leaching during spring and summer, over a three-year period. Additionally, we examined to what extent root growth and NO3-N leaching explain the well-known difference found between apparent and isotopic N reco...
متن کاملSpring Central Sectional Sampler
The Zimmer program refers to a number of questions and conjectures posed by Robert Zimmer in the 1980s concerning smooth actions of lattices in higher-rank Lie groups. We report on some recent progress by the author and collaborators. Lattices in Higher-Rank Lie Groups The primary objects inmy talk are lattices Γ in higher-rank simple Lie groups G. The simplest example of such a lattice is Γ = ...
متن کاملThermal Zoning of Spring Safflower in Isfahan Province, Central Iran
Many crops are grown in regions and sowing dates which the climate is not in the desirable condition, bringing about decreases in efficiency of agricultural inputs and crop yield. The spring safflower is planted under irrigation condition in Isfahan province and the temperature during growing season plays a major role in its seed yield. For thermal zoning of spring safflower planting in Isfah...
