Grain Drying & Storage

Humidity-Safe Grain Storage for Italian Farms

Drying methods, moisture thresholds, and storage conditions for wheat, maize, and other cereals — focused on the climatic realities of Italian agriculture.

Why moisture content matters after harvest

Grain stored above safe moisture levels is at risk from mould, mycotoxin development, insect activity, and weight loss. Correct drying before storage is one of the most critical steps in the post-harvest chain.

Regional considerations for Italian grain producers

Italy's grain production spans distinct climatic zones — from the humid Po Valley in the north to the drier conditions of Sicily and Puglia. Drying and storage requirements vary significantly across these regions.

Northern Italy
Po Valley: high humidity at harvest

Maize and wheat harvested in Lombardy, Veneto, and Emilia-Romagna frequently arrives at the dryer above 20% moisture due to autumn rainfall. High-capacity continuous-flow dryers are the standard for farm operations above 500 hectares in these areas.

Southern Italy
Puglia and Sicily: heat and storage risk

Durum wheat in southern regions often comes off the combine at lower moisture levels, reducing drying costs. However, high ambient temperatures during summer storage create conditions where insect infestations can develop rapidly if aeration is not managed actively.
