Corn and Soil Test Response to By-Product Nitrogen Sources

Author: Stanley Henning (Iowa State University)

Abstract

Bio-fermentation industries generate large volumes of nitrogen (N)rich by-products that are alternative N sources. Two such by-products are Heartland Lysine Fertilizer(HLF) and ProteFerm (ProF). Each contains organic N from microbial biomass and inorganic N from anhydrous ammonia combined with chloride or sulfate, respectively. Biomass is the remains of micro organisms that produced the amino acid. Both by-products contain approximately 6.5 to 7% total N. ProF possesses about 12 to 13% chloride (Cl) while HLF has about 5% sulfur(S) assulfate (SO₄).
