It describes water‐use efficiency when discussing the results of the Rodale Research Center experiments The chapter explains the absence of or minimal use of pesticides in low‐input systems It considers the effects on soil structure and biological activity and the implications of these effects on N losses and nitrogen‐use efficiency (NUE) Nitrogen use efficiency (NUE) can be defined in different ways (Dobermann 2007) For example NUE can be defined as the ratio of yield to total N inputs also known as partial factor productivity (PFP) (Cassman et al 1998): (2) where NUE is often express as kg kg-1 Y is harvested crop yield (kg ha) and Water and nitrogen use efficiency in

Water-use efficiency (WUE) of wheat grain production is simply the grain yield of a crop divided by the water used by that crop Crop water-use is generally defined as transpiration plus evaporation but it can be useful to also include net run-off and drainage The most practical way of estimating water-use in the field is by measuring soil
