Question 1

How do I choose the right maize variety maturity for my farm location and soil type?

Accepted Answer

Maize maturity in the UK is classified by FAO number - the lower the number, the earlier the variety matures. Earlier-maturing varieties (FAO 160–190) are better suited to northern UK regions or cooler, heavier soils where the growing season is shorter. Later-maturing types (FAO 210–240) suit warmer, more southerly locations with longer growing seasons and can offer higher dry matter and starch yields where conditions allow.

Question 2

What dry matter percentage should I be targeting when harvesting maize for silage or AD?

Accepted Answer

For wholecrop silage, the optimal harvest dry matter is typically 28–35%, which balances starch content, fermentation quality and palatability. For AD use, slightly wider DM windows may be acceptable depending on your digester management. Harvesting too early results in low starch and poor fermentation, while delaying harvest risks excessive fibre and reduced digestibility.

Question 3

What seed treatments and establishment practices help maximise maize establishment in UK conditions?

Accepted Answer

Maize is sensitive to cold soils and slugs at establishment. We recommend drilling into soils that have consistently reached 8–10°C and ensuring adequate drainage and field preparation to minimise slug pressure. Seed treatments providing protection against soil-borne disease and seed corn fly are available on selected varieties. Using quality compost or digestate applications ahead of drilling can improve soil warmth and moisture retention, particularly on lighter soils.

Question 4

Can I grow maize as part of a diversified rotation alongside other AD crops such as hybrid rye?

Accepted Answer

Yes, and this is strongly recommended for AD operators seeking to secure year-round raw material supply and reduce the risk of total crop failure. Pairing winter-harvested hybrid rye wholecrop with spring-drilled maize silage creates a complementary cropping programme that spreads workload, manages soil risk and smooths digester feeding across the calendar year.
