Quality Control for Corn Products

Like other commodities, the price of corn in the grain trading market is driven by both corn quality and availability. Whether you are a corn grower, environmental scientist, grain supplier, or food producer, end-to-end analysis technologies from KPM Analytics can help you command corn quality everywhere it matters.

Moisture and Compositional Analysis

Moisture and Compositional Analysis

Food grade corn varieties used in food production or to feed livestock receive their grades from the USDA and other entities based on certain measurable quality parameters, with moisture content and testing weight being two of the more important factors. These parameters also dictate the price of corn that is sold to food producers, so having verifiable data on corn moisture and test weight can save companies from paying too much for a lesser-quality corn delivery.

Parameters Measured

Parameters Measured

Type of Corn Role in Food Production Parameters Measured
Field Corn (yellow dent corn)
Generally used in livestock feeds, but also processed for other corn products, including corn syrup. Moisture, Oil, Protein, Ash, Fiber, Test Weight, Starch
Sweet Corn This type of corn is most consumed by people. It is often harvested in earlier stages when its taste is at its sweetest. Moisture, Oil, Protein, Ash, Fiber, Test Weight, Starch
White Corn
Another type of corn consumed by people. White corn is commonly processed into other food products, like snack foods, tortillas, flours, and others.  Moisture, Oil, Protein, Ash, Fiber, Test Weight, Starch
Popping Corn This corn variety inherently has lower moisture content to others, which lends itself best to produce seeds for popcorn. Moisture, Oil, Protein, Ash, Fiber, Test Weight, Starch
High-Starch (waxy) Corn High-starch corn is a white corn that is often used for fuel ethanol production and as a distiller’s grain (DDGS), but also fed to livestock. Moisture, Oil, Protein, Ash, Fiber, Test Weight, Starch

Analysis of Agricultural Soil Extracts

Corn is a robust crop that is grown in many climates and in many soil types around the world. However, with rising fertilizer costs, corn growers can save themselves from unnecessarily applying soil nutrients by routinely checking soil conditions. Taking unforeseen weather or man-made events that can impact a growing season out of the equation, there are certain controllable soil parameters corn growers to ensure a successful harvest.

Parameter Why It's Analyzed
Nitrogen-Based Nutrients (Ammonia, Urea, TKN, Nitrate, Nitrite) Nitrogen, while important to corn crop growth, may need to be controlled to limit ground water contamination issues. This is most common with dry, sandy soils. Urea and TKN content also have a role in animal feed quality.
Phosphorus-Based Nutrients (TP, o-Phosphate, Phosphate) Phosphorus may need to be added via fertilizer at different stages of the growing season.
Potassium Potassium may need to be added via fertilizer at different stages of the growing season.
Other Compounds in Crop Production Boron, copper, iron, manganese, zinc, and other minerals all have a role in corn crop production.
