Maximum Farming

Putting It All Together for Maximum Success

Soil provides a nurturing bed for seedlings and contains a multitude of primary, secondary and trace nutrients necessary for a plant’s optimum health. However, a plant’s genetic performance is limited by the least available nutrient and its ability to uptake nutrients at the right time. Highly productive soils feature a healthy microbial community and result in increased nutritional quality, increased genetic performance, and increased yields.


Plant growth and development depends upon maximizing the effects of photosynthesis. Enrich plant health by planting seeds in productive soils, getting the stand off to a good start, provide the right nutrients when the plant can use it most, and identify potential stresses and ways to minimize those stresses before they hit.  A healthy plant features broad leaves and full kernels/pods.


Energy drives the entire crop production system through chemical, physical and biological processes.  The plant’s ability to harness the sun’s energy, to produce high-quality yields and transfer that energy to the kernel results in increased yields, improved feed quality, and ultimately increases your return on investment.


While achieving improvements to your bottom line and increasing yield are often the key measures for success in farming, we challenge you to think beyond traditional yields. Do you see early crop differentials compared to your neighbors? Have you measured the feed quality of your grain? Are you improving the microbial environment in your soil? The Maximum Farming System is more than yield data, it’s a way of life that improves the well-being of all.

Systems Approach Delivers the Breadth and Depth of Farming Responsibly

Farmers are, without doubt, a critically important resource needed to feed a rapidly growing global population. However, those same producers face a challenging paradox: balancing environmental concerns while maintaining soil productivity and still earning an income.

As advocates for sustainable farming practices, growers attempt to minimize agricultural run-off, reduce nutrient loss in fields, and maximize nutrient uptake. Farmers with tightened budgets are beginning to reexamine their approach to soil...

5th Generation Indiana Farm Family Make Soil Priority

Strolling across Charlie Fox’s farm in Seymour, Indiana, you see a farming operation inspired by innovation and a responsibility for sustainable farming. The 5th generation farm has advanced agriculture by pioneering innovative conservation practices. The Fox family has used the Maximum Farming System for six years and recognizes that success starts with understanding the soil.

The farm was originally established by Fox’s great grandfather after he returned from the Civil War more than 150 years ago. Throughout the years...

Determined Farmer Saves Farm with Help of the Maximum Farming System

When Chris Pettz harvested the last of his crops in the fall of 2005, he wasn’t sure what the future would hold.

“Five years after converting from flood irrigation to center pivot irrigation, I was seeing some yield loss. Our yields were actually declining with the new irrigation system, and herbicides and insecticides weren’t working anymore either. Everything was gradually declining,” Pettz said.

Pettz farms for non-profit landowner, Garden City Company, and the majority of his fields are located...

These soybean leaves are indicative of a potassium deficiency.

A Controversy that has Cost Farmers Countless Dollars

American farmers have spent nearly $34 billion on Potassium since 1980. Has this investment actually contributed to an increase in yield or crop quality? Not according to a recent peer reviewed research study authored by S.A. Kahn, R.L. Mulvaney and T.R. Ellsworth that found that after a survey of more than 2,100 yield response trials it was confirmed that Potassium Chloride (KCl) fertilization is unlikely to increase crop yield. Contrary to the instilled perception of KCl as a valuable commodity, more than 1,400 field trials...

Research Continues to Prove Effectiveness of the Maximum Farming System

The art of foliar feeding production crops is a hot agricultural topic that is gaining ground and publicity. An increasing number of farmers are using the practice to fine-tune their nutrient strategies to create a better crop stand and maximize yields.

A leading industry expert in foliar nutrition, Dr. Patrick Brown and his team of researchers from the University of California, Davis have been in collaboration with Ag Spectrum to conduct research that furthers the understanding of foliar feeding in the...
