Abstract

Statistical comparisons of nitrate losses between sample locations and N treatments revealed N treatment to be less significant than the field sampling location. However, sludge amended soils had significantly higher levels of nitrates in the root zone and consequently suffered higher nitrate leaching losses. A NO3-N profile (30-210cm) balance indicated that about 40% of available NO3-N was leached below the root zone (0-150cm) in the upper two-thirds of the field plots during the pre-plant irrigation, whereas the lower one-third did not experience significant nitrate losses below the root zone. A one-dimensional finite difference layered model was used to estimate the depth of moisture penetration at the field (furrow) locations following pre-plant irrigation. It was concluded that the lower one-third of the plots received less than 50% of mean plot application (30cm) water during pre-plant irrigation. -from Author
