Sunn hemp cover cropping and organic fertilizer effects on the nematode community under temperate growing conditions.
Field experiments were conducted in Maryland to investigate the influence of sunn hemp cover cropping in conjunction with organic and synthetic fertilizers on the nematode community in a zucchini cropping system. Two field treatments, zucchini planted into a sunn hemp living and surface mulch (SH) and zucchini planted into bare-ground (BG) were established during three field seasons from 2009 t...
متن کاملPredicting nitrogen fertilizer requirements for corn by chlorophyll meter under different N availability conditions
Rashid, M. T., Voroney, P. and Parkin, G. 2005. Predicting nitrogen fertilizer requirements for corn by chlorophyll meter under different N availability conditions. Can. J. Soil Sci. 85: 149–159. Nitrogen management strategies that enhance fertilizer use efficiency and maximize profitability in corn require a rapid and accurate method to determine the crop N needs of current hybrids. The object...
متن کاملReplacing bare fallows with cover crops in fertilizer-intensive cropping systems: A meta-analysis of crop yield and N dynamics
The availability of Haber-Bosch nitrogen (N) has permitted agricultural intensification and increased the productive capacity of agroecosystems; however, approximately 50% of this applied fertilizer N is lost from agricultural landscapes. Extensive efforts have been devoted to improving the N use efficiency of these systems. Diversified crop rotations using cover crops to provide a variety of e...
متن کاملResponse of Maize to Cover Crops, Fertilizer Nitrogen Rates, and Economic Return
17 Maize is the world’s most widely grown cereal on the basis of Mg produced (FAO, 2014). Nitrogen fertilizer applied to cropland is a considerable portion of the cost and energy input associated with nonlegume crop production (Liebman et al., 2012). When N is lost from cropland, it represents both a fi nancial loss to producers and has a potentially negative impact on the environment (Vetsch a...
متن کاملNitrogen uptake from N-enriched fertilizer by four tree crops in an Amazonian agroforest
Mixed tree cropping systems have been proposed for sustainable nutrient management in the humid tropics. Yet, the nutrient interactions between intercropped trees have not been addressed sufficiently. In the present study we compare the temporal and spatial patterns of the uptake of applied N by four different tree crops in a mixed tree cropping system on a Xanthic Ferralsol in central Amazônia...
