As we get closer to closing up harvest season, what about harvesting the unharvested crop? Crop Residues unmanaged can be problematic if not broken down, but can be a great tool in soil health. As crop residues break down, they can be a fantastic source of nutrients, carbon, and protecting soils and building soil organic matter and microbiology. How do we better utilize crop residues? How can we aid in their decomposition for improving soil health? FERTIL HUMUS® is the answer!
Crop Residue Management Program
Solution: FERTIL HUMUS (24-0-0 with Fe, Mn, Zn) liquid stubble digester/soil enhancer creates an environment to break down stubble/stover into humus.
Application: Spray directly to the soil or stubble/stover anytime following harvest (the sooner the better).
Rate: 1-2pt/ac broadcast application ($7.00 – $14.00/ac MSRP)
Objectives:
Feed the Soil
• Carbon-based, excellent nutrient recycler
• Promote biological diversity and activity
• Accelerate microbial populations by providing the top food source for beneficial fungus
• Rapidly shift from bacteria to fungal dominated organisms
• Buffer harsh chemicals and degrade toxic compounds in the soil
• As microbe diversity and populations increase, soil resilience to abiotic and biotic stress decreases
• Ideal for use with manure, breaks down manure to dramatically increase bioavailability
• Can replace cover crops in areas where cover cropping is not viable
Fertilizer Savings
• Release N, P, K, and carbon tied up in the crop residue
• Increases recycling of carbon and nutrients tied up in organic matter
• Aids in the decomposition of organic residues in soils, converting them to humus and nutrients
• Catalyst for strengthening the microbial activity in the rhizosphere for the next crop
• Builds organic matter
Promote Minimum and No-Till Practices
• Ultimate composter: maintains stubble/stover benefits over winter by protecting the soil; turns stubble/stover into finished compost prior to spring planting by composting residue all winter long
• Eliminates stubble bunching during a planned spring tillage pass, eliminating the need to run a disk in the fall
• High N content aiding in proper C:N ratios
• Strengthens water penetration and water holding capacity
• Rapidly improves soil structure and compaction issues
• Soils warm up quicker in the spring, may reduce the need to till the soil in the spring
Recycle last year’s nutrients for this year’s crop
FERTIL HUMUS will recycle and unlock 25-30% more of the stubble nutrient content (especially Carbon) contained in the stubble/stover from the previous crop – making more of those nutrients available this season. Corn stalks* from a 200 bu/ac crop can contain about 100 lb/ac of N, 50 lb/ac of P and 210 lb/ac of K. Soybean residue* from a 60 bu/ac crop contains about 34 lb/ac of N, 6 lb/ac of P and 26 lb/ac of K. Wheat straw* from a 60 bu/ac crop contains 33 lb/ac of N, 9 lb/ac of P and 45 lb/ac of K. The trick is capturing these nutrients and making them bioavailable for the next crop. FERTIL HUMUS quickly breaks down the stover/stubble and captures the nutrients in the soil, where they can be consumed by the following year’s crop. Applying FERTIL HUMUS in the fall means you can significantly reduce your NPK fertilizer rates the following year.
Reduce the need to disk stubble in the fall – Eliminate 0.63 gal of diesel fuel per acre**. Pulling a disk requires 0.74 gal/ac of diesel fuel, while operating a sprayer requires 0.11 gal/ac. So, you dramatically reduce the expenses and carbon emissions from disking in the fall.
Reduce the need to work the soil in the spring – Eliminate another 0.74 gal/ac of fuel per acre** by not having to run a field cultivator or disk in the spring. Last year’s stover will turn into compost, allowing the planter to operate easily across the soil with little disruption.
In areas where cover cropping is not viable, FERTIL HUMUS can provide many of the same benefits as cover crops. Rain and snow can incorporate the product into the soil.

One of the greatest inventions in history is the combine. The concept of threshing and separating grain in one operation revolutionized our food system, as well as redefined our labor force. Consider that in the mid-1800s, 90% of the US workforce was involved in some aspect of farming. Now it’s under 2%. To think my grandfather harvested corn by hand and threw the ears in a wagon! He used the pull-behind model in the 1940s to harvest small grains (that’s him, Fred Nichols, combining oats on our family farm). My mother still talks about dad wearing a Jesse James style mask while operating their first self-propelled combine without a cab.
Where Did the Water Go?
By Jared Alder, MS In England, it is estimated that around 700 million gallons of water—the equivalent of 1,200 Olympics–size swimming pools—is lost every day to leaks in the country’s vast water system. Often the water just rises out to the pavement and runs down the road. Utilities spend countless hours and a great deal of money and other resources trying to locate the sources of leaks, often tearing up roads multiple times in
