When preparing the soil for seeding, make sure that the seedbed has a rough surface layer covering a layer of fine soil with a firm base. The more the earth is liable to form a crust, the rougher the surface should be.
A layer of fine earth will ensure good contact between the seed and the surrounding soil, while the base ensures a good supply of water. Take into account the types of soil, crop rotation and crop debris management. Have a granulometric analysis done to know what type of soil you have. Soils with high clay content compact easily but, if well-drained, they are very suitable for reduced tillage techniques in a well-established crop rotation.
Sandy soils dry out rapidly and should only be worked in the springtime, leaving any organic residues on the surface to encourage water conservation. Silty soils are cold and contain a lot of water. Turning this type of soil allows it to drain but reduces the likelihood of crust formation. If you have a dairy or large crop farm, choose farm implements which allow for rapid and efficient working without harming the quality of the soil or the harvests.
If you produce vegetables, take into account the type of seed to be used. The soil should be finer but be careful with soils which tend to form a crust and leave small clumps on the surface rather than reducing the soil to dust.
