December newsletter
December, 2023

The most important article in this issue of the newsletter is a summary of some recent research we conducted in our soil health lab. Some farmers have expressed concerns that Biocat 1000 may decay cover crop seeds when the product is applied while fall covers are grown. We show that Biocat 1000 does not affect the germination rate or early seedling growth of annual rye seeds. We also focus on the upcoming National No-Till Conference and Soil Health U, and we provide our winter show schedule, spring discount prices, and some interesting information about weed seed dormancy.

September newsletter
September, 2023

In the September newsletter, we highlight our latest webinar with No-Till Farmer. The title of the presentation was “Practical Answers to Common Questions about Residue Decay,” and we review our answers to questions about the decay process that are frequently asked by farmers. We also update the value of recycled corn and bean residue, discuss weed seed decay, and introduce the latest research on seed exudates.

June, 2023

This newsletter focuses on several topics, including the impact of dry weather on sulfur availability and the chances that El Nino returns in 2023. We also announce our eleventh free webinar with No-Till Farmer on August 17 as well as some upcoming changes to our farm show schedule. We conclude with a review of the latest research on the impact of sounds on plant growth.

March, 2023

We celebrate the thirtieth anniversary of our first newsletter published in March, 1993. We also promote the upcoming National Cover Crop Summit, which will be held online from March 15 to 17. The difference between the Chandler crop products and other types of biological products are explained, and we update the expected returns from using the crop products this spring.

On this page, we post a summary of the topics covered in each newsletter published in the past few years. You can also access a PDF version of the newsletter file by clicking on the newsletter image.


December, 2022

We begin this newsletter by noting that much of the current interest in biological crop products is due to high fertilizer prices. While we have documented the potential savings from increasing biological activity, we also explain that there are many other benefits from improved soil health. We report some recent field results from our users, and we update the estimated net returns from the Chandler crop products. The newsletter concludes with our winter show schedule, including two new farm shows in Iowa and Nebraska.

September, 2022

In this edition, we discuss recent trends in commercial fertilizer prices and project the nutrient value per ton of corn and soybean residue. Then, we estimate the expected net returns from accelerating crop residue decay with Chandler Biocat 1000. We also present the latest side-by-side on-farm test results from Biocat 1000 applied to corn stalks in northern Illinois. Finally, the newsletter includes our fall discount price list, and the program runs from September 1 to October 31.

June, 2022

Our first article announces that Jim Miller recently celebrated his 90th birthday. Midwest Bio-Tech was founded by Jim and Carole Miller in November, 1981. The interior of the newsletter focuses on photosynthesis and the impact of early planting dates on soybean yields. We also update the estimated net return from using Chandler Foliar on soybeans and using Chandler Seed Treat and Biocat 1000 on wheat. Other news items include our sponsorship of the 2022 National Strip Tillage Conference and a new special report on cover crops. We also include general interest articles on the use of lignin in road construction, enzymes and plastic recycling, and battery-powered chemical transfer pumps.

March, 2022

We begin with a summary of our tenth webinar co-hosted with No-Till Farmer. During the webinar, Doug Miller discussed the top ten lessons we have learned about soil fertility over the past 40 years. We also present some recent results for Chandler Foliar applied to soybeans, and we discuss the emergence of tar spot, which is a fungal disease that can sharply reduce corn yields. Tar spot remains in undecayed residue over winter, so you can reduce the problem by accelerating corn residue decay. Finally, we discuss the latest research on corn response to nitrogen during droughts, the National Cover Crop Summit, and our observations from the winter farm shows.


December, 2021

This newsletter celebrates the 40th anniversary of Midwest Bio-Tech, which was founded by James and Carole Miller in November, 1981. We reminisce about some of the changes in the world and farming since 1981, and we highlight some of the key changes in our business over the past 40 years. Although we had to raise product prices for the first time in six years, we demonstrate the continued value of the Chandler products in crop farming through the estimated net returns per acre for 2022. This issue concludes with our full winter show schedule for 2021-2022.

September, 2021

Our lead article provides some basic facts about building soil organic matter and the associated impacts on water holding capacity and fertility. Due to sharply higher fertilizer prices this fall, the expected net returns from recycling nutrients from corn and soybean residue are also much higher than last year. We then answer some common questions about residue decay, including the role of moisture, temperature, and nitrogen. We also discuss some upcoming events that we sponsor, including the National Cover Crop Summit in November and the National No-Till Conference in January, 2022.

June, 2021

We begin with the private benefits of building soil carbon levels. Private benefits are those enjoyed by the farmer or landowner, and these are distinct from the external benefits that outsiders are willing to pay for through carbon contracts. The private benefits of building soil organic matter include improved water infiltration, better water holding capacity, and higher nutrient bonding capacity. We also discuss the benefits and expected returns from Chandler Foliar as well as the basic functions of photosynthesis. Finally, we provide some field scouting notes for new users of Chandler Seed Treat.

March, 2021

Midwest Bio-Tech hosted our ninth webinar with No-Till Farmer on February 25. The title of the presentation was “Measuring and Managing Soil Carbon.” In addition to these topics, Doug Miller reported new results on managing active carbon gathered by the Soil Health Lab. As well, we report recent yield gains from an in-row application of Chandler Soil to soybeans plus the expected net returns from the other crop products. Unfortunately, we only had one farm show this winter. Further, all of our March customer appreciation meetings were canceled due to COVID.


December, 2020

For the first time, Midwest Bio-Tech is a title sponsor of the National No-Till Conference, which is a virtual event for 2021. We report field results from a Chandler user who cut NPK rates in 2020 and maintained his yields. As well, we show the microbial response to Chandler Soil, humic acid, and molasses. Finally, we discuss our spring discounts and the updated winter show schedule.
