水分和成分分析

用于食品生产或饲料牲畜的食品级玉米品种根据某些可测量的质量参数从美国农业部和其他实体获得分级，其中水分含量和测试重量是两个更重要的因素。这些参数还决定了出售给食品生产商的玉米的价格，因此，拥有可验证的玉米水分和测试重量数据可以使公司不必为质量较差的玉米交付过多费用。

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

玉米是一种强壮的作物，可以在世界各地的许多气候和多种土壤类型中生长。但是，随着化肥成本的上涨，玉米种植者可以通过定期检查土壤状况来避免不必要地使用土壤养分。将可能影响生长季节的不可预见的天气或人为事件排除在外，玉米种植者有某些可控的土壤参数可以确保成功收割。

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.
