Cover crops act as green manure adding organic matter to agricultural-soils. For legume green manures to be an effective nitrogen (N) source for organic farming systems, their N release must be in synchrony with crop N demand. The objectives of this study were 1) determine the decomposition rates of three common cover crops (white clover, (Trifolium repens,L) red clover (Trifolium pratense L.) ...

white clover is positively correlated with increased size of plant parts and reduced leaf density per unit area The plasticity of white clover (Trifolium repens L.) results in (Beinhart et al., 1963). changes in plant habit in response to different environmental stresses. The objective of this research was to characterize those morphological Defoliation through grazing or clipping is a managech...

We present preliminary results of light hadron spectroscopy using valence, tadpole-improved, Clover fermions on an ensemble of gauge configurations generated with 2 flavors of staggered fermions at β = 5.6. We compare the slope and intercept of the curve MV vs. M 2 P S for Clover and Wilson fermions. We show that a higher order chiral perturbation theory ansatz works very well for chiral extrap...

For the Stout Link Non-perturbative Clover (SLiNC) action we determine in one-loop lattice perturbation theory the critical hopping parameter κc and the clover parameter cSW which is needed for O(a) improvement. Performing this calculation off-shell we are also able to compute the non gauge invariant quark field improvement coefficient cNGI . Additionally, we present first results for the renor...

erates frequent defoliation in monoculture (Peterson et al., 1994) or in binary mixture with grass (Kim, 1996) Improved dry matter (DM) production of cool-season grass monoand is suitable for hay or pasture production in this cultures may result from either N fertilization or the addition of legumes such as kura clover (Trifolium ambiguum M. Bieb.) or birdsregion (Sheaffer and Marten, 1991; She...

The sequestration in soil of organic carbon (SOC) derived from atmospheric carbon dioxide (CO2) by replacing arable crops with leys, has been measured over 70 years on a sandy loam soil. The experiment was designed initially to test the effect of leys on the yields of arable crops. A 3-year grazed grass with clover (grass + clover) ley in a 5-year rotation with arable crops increased percentage...
