Quality standards
Corn must comply with quality requirements established by national and international standards. In Ukraine, the primary standard is DSTU 4525:2006, which defines grain classes, allowable moisture levels, impurities, and damaged grain content. In international trade, GAFTA and ISO standards are commonly used to regulate basic quality parameters for export. The grain must be sound, free from mold, self-heating, foreign odors, and pest infestation.

About culture
Corn is one of the most important cereal crops in the world, widely used in food production, feed industry, and bioenergy. It is a key raw material for compound feed, starch, bioethanol, and various industrial products. Ukraine is among the leading exporters of corn globally, supplying stable volumes to international markets. Due to its high yield and versatility, corn plays a crucial role in the agricultural economy.
Planting and care
Corn is primarily grown as a spring crop that requires warmth and adequate moisture. It performs best on fertile soils with neutral or slightly acidic pH. Key success factors include proper hybrid selection, optimal planting time, fertilization, and effective control of weeds and pests. Modern cultivation technologies involve high-yield hybrids, precision farming, and advanced crop protection systems.
Harvesting
Corn is harvested at full maturity when grain moisture decreases to levels suitable for storage or drying. Timely harvesting is essential to prevent losses due to grain damage or field losses. After harvesting, corn is cleaned, dried, and stored in specialized facilities. Proper post-harvest handling ensures grain quality preservation and competitiveness in the market.
