Different doses of effluent have been examined in combination
with different types of chemical fertilizers in agricultural
fields, and there are reports of both positive and negative
effects. For example, Joshi et al. (1998) recommended four
post-sowing irrigation with diluted effluent in combination
with a 50 NPK treatment to achieve the best results. The
majority of such studies has focused on macronutrients, and
to our knowledge, there are no studies have been conducted
on the impacts of effluent on plant response to micronutrients
application.
