No-Till Operational Benchmark Study

Fertilizer Expenses Creep Upward

After slashing their fertilizer bill nearly 27% in 2016, no-tillers battled to keep their spending on applied nutrients to a 4% increase last year.
After having made considerable cuts to their fertilizer spending in 2016, No-Till Farmer readers fought hard to hold on to those dollars in a bid to stay profitable in 2017. They did well, for the most part.

Fox River Demo Farms Project Overview

Brent Petersen, with the Brown County, Wis., Land & Water Conservation Department, overviews the Lower Fox Demonstration Farms Network. The "Fox Demo Farms" is a Great Lakes Restoration Initiative (GLRI) project involving six farmers that is designed to showcase and demonstrate leading edge conservation practices that improve Great Lakes water quality by reducing phosphorus from entering Green Bay and Lake Michigan.

Insights into Grain Phosphorus and Potassium Numbers

Corn and soybean take up relatively large amounts of phosphorus (P) and potassium (K), and much of this P and K ends up in the grain that is taken off the field during harvest. In order to keep soil nutrient levels from dropping over time, the amounts removed need to be replaced by applying fertilizer or manure. In order to know how much nutrient a crop removes, we need to know how much there is in a bushel of harvested grain.

Why Phosphorus is Leaving the Farm and What to Do About it - Joe Nester - NNTC 2016 Presentation - MP3 Download

$19.95

Phosphorus has come under fire lately, especially around Lake Erie where toxic, blue-green algae blooms caused by phosphorus runoff have plagued the lake’s western basin the last several years. Why is this happening? Nester Ag owner and independent crop consultant Joe Nester from Bryan in northwest Ohio shares his thoughts on why phosphorus management is different today than it used to be. He talks about what practices no-tillers can employ on their farms to ensure their crops have adequate phosphorus while minimizing loss.

How Can I Place My ‘N’ and ‘P’ Better in a No-Till System? - John Fulton - NNTC 2016 Presentation - MP3 Download

$19.95

With environmental policies influencing the timing and placement of fertilizers, it’s important to improve the application toolbox without sacrificing farm profitability. Placing nitrogen and phosphorus below the soil surface has been a suggested way to reduce off-site transport of nutrients, but at times, field capacity (ac/hr) may be sacrificed. Moving forward, the ability to both accurately place nutrients and apply them at the right time will be important for the no-till operation. In this presentation, John Fulton discusses opportunities for timing and placement of nitrogen and phosphorus, and how new technology can help enhance delivery. The Ohio State ag engineer also discusses environmental risks, agronomic response and application field capacity, as well as tips to consider for success.
