The Elimination of H2S from Production Wastewater

Increased wheat yield

A wheat farmer near Canton, Oklahoma, had a 40 acre plot which had not been fertilized in 6 years. A soil test indicated he had 1 pound of nitrogen per acre.  He did not want to spend $800/ton for urea (46-0-0) to meet the recommended 200+ pounds of nitrogen to produce a 40 bushels/acre yield.  Part of the plot had been impacted by salt from a drilling operation several years previous. 

His goal was to bring the hard hit field back to productivity, and cut his fertilizer cost in half.

He applied 56 pounds of actual nitrogen/acre instead of the 200+ pounds recommended. 

The winter wheat was sprayed with a soil amendment containing several strains of beneficial soil bacterium, humic acid, a biological stimulant, and some liquid fertilizer at the recommended dosage.  A wheat sample was collected at that time, and analysed for protein content.  Two weeks later a second wheat sample was collected, and a forage analysis was performed.  The protein content had risen 26%. Historically, this field had yielded 15 bushels/acre.  This year the field yielded 28 bushels/acre for a 46% increase.  The farmer saved over $120/acre on fertilizer. The treated field yielded wheat heads that were full of seed and measured 4.75 inches versus an untreated area of the field that only yielded 1.75 inches and the heads were not fully seeded.  He also noted that the humic acid had broken down the clay content in the soil, allowing the moisture to penetrate instead of ponding on the surface in his terraces.  In addition, he attributed the improved yield to the humic acid detoxifying the salt in the soil allowing the nutrients to be released.  The farmer was pleased with his investment and soil improvements, particularly under the severe drought conditions  Oklahoma is currently experiencing.
