fragmented into shorter chains or more oxidized components. Previous studies have demonstrated that crop residues from rice fields or composted rice hulls contain numerous secondary metabolites (see review by Rimando and Duke, 2003 ). The PBH used in this
depth, crop residue, soil air permeability, soil aggregation, and seed carbohydrate reserves resulting from seed size can influence weed emergence ( Benvenuti, 2003 ; Chauhan and Johnson, 2008 ). Soil texture and seed burial depth reportedly influence

asparagus was a serious weed problem. Traditional asparagus production included one or two tillings of asparagus fields each year for weed control and to incorporate previous year crop residue. However, it has been demonstrated that tillage reduces yield

2006 trial, it is likely the increased disease pressure in 2007 was due in part to the crop residue and associated FON remaining from the 2006 planting. In addition, there was more precipitation in 2006 than in 2007, and this may have resulted in higher

A brief review of slow-release fertilizer technology Slow-release nitrogen fertilizers can be separated into three broad categories. The first is “natural” organic fertilizer, with the N contained as a part of crop residue, animal waste, or other
market premium for produce. Unpredictable spring weather can complicate cover crop residue management and delay spring planting. Even where a cover crop is produced, its N contribution may be inadequate to supply high-N demand crops, and other organic N
