Sorting through nutrient management marketing claims

Farmer and advisor in a corn field putting precision agriculture technology to use

Farmers need assurance that a nutrient management tool is worth their investment.

Farmers and their advisors face increasing challenges from low crop prices, extreme weather and pressure to improve water quality. A growing marketplace of tools and products promises to help meet these challenges, but has in turn created a new problem: information overload.

This problem is especially acute for precision management of nutrients, one of the fastest growing agricultural sub-sectors. Companies promise their nutrient efficiency tools and products will enable farmers to grow more with less, save money and boost yields. But there is often little available data behind these claims.

As one of the farmers I regularly turn to for advice put it, “We (farmers) need a ‘Big Sort’” – something that sorts through this flood of information, separates the wheat from the chaff and helps farmers make informed decisions about what will work best for them.

To initiate this “Big Sort,” Environmental Defense Fund (EDF) teamed up with a group of experts in technology and nutrient management to develop NutrientStar, which helps farmers determine which products deliver on their promises and are worth the investment. Read More »

New guidance to maximize every drop of fertilizer in Ohio and beyond

Maximize every drop of fertilizerApplying the right amount of fertilizer to a grower’s field is tricky: too little fertilizer means lost yields; too much fertilizer means wasted costs and potential runoff that causes air and water pollution. Meanwhile, farmers cannot control the weather, which can wreak havoc on the best-laid plans.

One important tool used to answer the question of the right rate, timing, placement and source of nutrient application to croplands (the “4Rs”) is on-farm research trials. Farmers establish trials using their own fields and equipment, usually with guidance from a trusted advisor, university researcher or extension agent. Trials can inform many practices like nutrient management and seeding rate. Typically, they are conducted to determine practices’ effects on yield, nutrient use efficiency, soil health and profitability.

Using the data generated from these field trials, experts are now updating the Tri-State Fertility Guide for Corn, Soybean, Wheat and Alfalfa. This 22-year old document still serves as the main guidance on fertilizer applications for the Buckeye state as well as Michigan and Indiana.

Here’s how the update will benefit farmers. Read More »
