From North Dakota to New York to Georgia, soybean yields from planned on-farm field trials indicate the benefits of improving the in-furrow environment for the seed. During the 2013 crop season, even with challenging soybean growing conditions, when many areas faced late-season heat and drought, the effects of in-furrow fertilization and seed protection gave soybean plants a boost, generating positive yield results in 72 percent of 91 plots across 16 states.
Nachurs liquid fertilizer and FMC Corporation partnered with 91 American Soybean Association (ASA) member growers across the soybean belt on a joint venture. The program was an on-farm field trial called “Soy Booster.” Participants used FMC’s Capture LFR (Liquid Fertilizer Ready) insecticide and Nachurs HKW6 liquid starter fertilizer on soybeans. The trial gave growers the opportunity to observe for themselves how the application of insecticide with starter fertilizer could enhance profitable production on their farm. Each grower devoted 20 acres of treated and 20 acres of untreated soybeans in the trial.
Nachurs spokespersons are definite in their contention that emerging soybean plants benefit when fertilizer is placed in-furrow, with a seed-safe source of fertilizer. Banded fertilization reduces tie-up with the soil and increases availability to the young plant. The proximity of the fertilizer to the seed ensures adequate fertility at all times, even before roots are able to mature to the point they can extract other nutrients which may be nearby.
With seed-placed fertilization, risks associated with growing season stresses are reduced, according to Nachurs and several university personnel who see starter fertilizer in soybeans as a good way to complement nutrients that may have been removed by other crops in a rotation. Like corn or wheat, soybeans require immediate availability of balanced nutrients to ensure they have a good start to the growing season.
Since soybeans are a salt sensitive seed, many universities do not recommend seed placed fertilizers because of the fear of decreased germination. Iowa State University information has stated observations that lead to a conclusion that dry conditions and decreased germination from in-furrow fertilization results in decreased yield, but in good growing conditions the reduced germination did not lead to decreased yield.
Nachurs HKW6 fertilizer is the answer to these concerns, according to the company. This fertilizer delivers seed safety allowing soybeans to receive the boost from banding fertilizers, which normally only other crops are able to capitalize upon.
Seed safety results from the raw ingredients used. Most salt injury occurs because of the nitrogen or potassium source used in a fertilizer. The Nachurs fertilizer is formulated with different materials. It is especially important to understand that potassium phosphate (formed by potassium hydroxide combined with phosphoric acid) and potassium acetate are much safer than other sources available, claims Nachurs specialists.
Additionally, 20 out of 21 field trials conducted in the 2011- 2012 growing season proved benefits for soybean production can be achieved with a timely application of Nachurs N-Rage foliar fertilization. The trials showed an average yield increase of 7.89 bushels per acre. Nachurs N-Rage fertilizer is most effective when applied at R1-R3 growth stage and may be applied with other crop protection chemicals, the data shows.
