Have you ever wondered where fertilizer actually comes from? Darren Hefty explains in this week's Ag Minute.

In this Ag PhD episode, the Hefty brothers discuss how much a soil temp can vary during the day, what to consider when applying elemental sulfur, and when you should incorporate your soil-applied herbicide.

Brian and Darren discuss considerations when it comes to applying elemental sulfur to your fields.

Join us as agronomic field representative Ashley Babl, walks us through the impact of CEC, Organic Matter, soil pH and Buffer Index on your soil fertility and irrigation management.

Brian and Darren Hefty discuss tiling and ditching, their trials with silica, and weed control and more in dry beans. The Weed of the Week is crabgrass. Plus we talk about how drought can actually help you prepare variable rate planting maps.

Are you measuring your silica content in your soil and crops? Brian and Darren talk about the latest developments with silica use in agriculture.

Brian and Darren talk weed control in this crop not often discussed by the Heftys. Plus they give their input on insects, diseases, and fertility in dry beans.

Darren Hefty talks about how too much salt is harmful to plants.

This week, the Hefty brothers discuss how many ears of corn can be on a single plant, how to fight corn smut, and how to increase or decrease soil organic matter.

Darren Hefty talks about equipment to consider when making multiple nitrogen applications during the season.

The Hefty brothers talk about the importance of organic matter in soil and how you can either increase it or deplete it over the years.

Brian & Darren talk about the mobility of nutrients within your crop, fixing salty soils, and corn on corn management. The Weed of The Week is the awful musk thistle. Plus the Iron Talk concerns how to apply dry seed treatments correctly on your planter.

Many nutrients are mobile in the plant but some are not. You can see what plant food you are short on by looking at where the discolored leaves occur on your crop.

Corn on corn has to be handled much differently than when rotating. You need to take a different approach to fertility, insect, disease and residue management.

Darren and Brian explain what Bt corn is, how to do common fertility conversions when reading a soil test, and how to maximize tonnage and quality in your alfalfa crop.

Darren Hefty explains how to apply micronutrients using either variable rate technology or making multiple passes.

Brian and Darren discuss ways to maximize your alfalfa tonnage.

Brian and Darren go over some of the common conversions you should know when reading a soil test and making fertility decisions.

Brian and Darren Hefty talk about the latest technology in the tractor cab, how to raise the best sunflower crop, and why sulfur is needed even more today than yesterday. Plus johnsongrass is the Weed of the Week, and Iron Talk is all about a new way to adjust your tires to the right rates for t...

What can farmers do after a drought season? Darren Hefty says extra tillage and fertility testing are two ways you can get next year's crops ready after a dry year.

S is very important nutrient for all of your crops. Brian & Darren talk about the many forms of sulfur available to use on your field and why sulfur is needed today more than ever.

The Hefty brothers discuss avoiding overlap when planting and spraying, how to test for and apply manganese, and how to keep your broadleaf herbicide and grass herbicide from working against each other.

Brian and Darren discuss testing for and applying manganese, an important micronutrient.

How do you know if: your seed will start right this spring, your stored grain will survive the winter, and your soil has enough copper in it? Brian and Darren Hefty answer these questions and talk swamp smartweed and soybean herbicide placement in this episode.
