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

Crops obtain required S from diverse sources including soil, crop residues, manures, irrigation water, rainfall, atmosphere, and soil amendments and fertilizers ( Tabatabai, 1984 ). In the past, the primary sources of S for crops were from
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
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
