Biosolids cut fertilizer costs by $200 an acre

In an attempt to gain a better understanding of nutrient utilization via nitrogen application, a field testplot was treated with biosolids in 1995. All 130 acres of a corn field received 5.8 dry tons of biosolids per acre, which provided an adequate level of plant-available nitrogen to produce a tar...

Description
Summary:In an attempt to gain a better understanding of nutrient utilization via nitrogen application, a field testplot was treated with biosolids in 1995. All 130 acres of a corn field received 5.8 dry tons of biosolids per acre, which provided an adequate level of plant-available nitrogen to produce a target yield goal of 150-160 bushels per acre. Herbicides and insecticide were also applied, and extensive soil sampling using pre-sidedress nitrate-nitrogen testing was carried out over the entire field. The first year data suggested that the prudent use of biosolids could replace several major costs of commercial fertilizers without risking yield loss.
