'Sustainable intensification' on the farm reduces soil nitrate losses, maintains crop yields

A nine-year study comparing a typical two-year corn and soybean rotation with a more intensive three-year rotation involving corn, cereal rye, soybean and winter wheat, found that the three-year system can dramatically reduce nitrogen—an important crop nutrient—in farm runoff without compromising yield.

Test soil to save money in 2025

University of Missouri Extension agronomist Todd Lorenz said a simple soil test helps farmers kick the habit of routine fertilization resulting in wasted money and poor crop performance. Soil tests remove the guesswork from deciding how much fertilizer to apply by providing an accurate inventory of nutrients available in the soil, Lorenz said. Applying too much fertilizer results in unnecessary costs and harm to the environment; too little ferti…

A Low Cost Alternative to Synthetic Fertilisers

An innovative project which aims to provide UK farmers and growers with a sustainable, environmentally friendly nutrient management solution is underway following a partnership between industry experts.     The project, called ‘Biofilm Biofertiliser’, will develop a novel multi-species biofilm-based biofertiliser product that reduces the use of synthetic fertilisers by 40-50%.     By utilising a unique consortium of UK indigenous biofilm-forming…

Ideal Nitrogen Fertilizer Rates in Corn Belt Have Been Climbing for Decades

AMES, Iowa — The amount of nitrogen fertilizer needed to maximize the profitability of corn production in the Midwest has been increasing by about 1.2% per year for the past three decades, according to new Iowa State University research. The study, published last month in Nature Communications, analyzed data from prior long- and short-term studies by Iowa State and the University of Illinois to calculate the Corn Belt’s steadily rising optimum n…
