Summary

Direct drilling has achieved results similar to conventional sowing techniques (including seedbed preparation) if the soil is well structured.
Practical recommendations
Observations and practical tips
• Pay attention to the soil structure when applying any mechanical operation. During the harvest, offloading should take place at the headlands.
• In the case of a high presence of deep-rooting weeds, choose a double-layer soil preparation (instead of compacting the soil) in order to increase porosity.
• Avoid sowing if heavy rains are expected in the next 5-6 days.
• Include cover crops in the rotation to improve soil structure. Cover crops are a key element to fine-tune direct drilling techniques.
• Directly drilled soil warms up more slowly in springtime. An early harrowing in springtime to facilitate nitrogen mobilization is recommended.
• Avoid crop residue coming into contact with the seeds (see link on hairpinning on page 2).
• To reduce the risk of mycotoxins, implement appropriate crop rotations and avoid sowing more than one winter cereal in a row or a winter cereal on corn residues with direct drilling.

Summary translation

La semina diretta ha ottenuto risultati produttivi paragonabili a quella tradizionale nel caso di terreni ben strutturati.
Raccomandazioni pratiche
Osservazioni e consigli pratici
• Rispettare la struttura del terreno durante tutte le operazioni meccaniche. Alla raccolta, effettuare le operazioni di scarico in capezzagna.
• Non ritardare le semine.
• Con una presenza elevata di specie spontanee con radice a fittone, indice di compattamento, preferire una preparazione a doppio strato del letto di semina per ripristinare la porosità.
• Non seminare se vi sono previsioni di piogge abbonadanti nella settimana successiviva alla semina.
• Inserire nella rotazione colture intercalari per migliorare la struttura del terreno. Queste colture sono una delle chiavi per mettere a punto la tecnica della semina diretta.
• Un terreno gestito con la semina diretta si riscalda più lentamente in primavera. Intervenire presto in primavera con un intervento di strigliatura per favorire la mobilitazione dell’azoto.
• Evitare il più possibile la presenza di residui colturali a contatto con il seme (vedi link hairpinning).
• Per ridurre il rischio legato alle micotossine adottare rotazioni adeguate evitando il ristoppio o la semina diretta su residui di mais.

EPrint Type:Practice tool
What problem does the tool address?:In crop rotations where winter cereals follow a crop harvested in autumn, it may be difficult to prepare the seedbed.
What solution does the tool offer?:The cereal can be directly sown, skipping the seedbed preparation, if the preceding crop left the soil well structured and free from weeds.
