The best method is ploughing and direct reseeding. A properly set plough should bury all surface trash then power harrow the top few centimetres avoiding bringing trash back to the surface. Once a fine tilth has been achieved the grass seed can be sown ideally no more than 0.5 cm deep. Grass seed requires a fine firm seedbed.
In some situations it may be appropriate to roll the cultivated ground before sowing to achieve the desired firmness. Loose fluffy seedbeds should be avoided at all cost. Rolling post sowing is essential to enhance seed to soil contact. A flat roller will provide better and more uniform firmness of the seedbed than a cambridge roller.
Fertiliser should be applied to the seedbed in order to provide approximately 60 kg/ha of nitrogen phosphate and potash. The pH should be checked before sowing and requires to be 6.0. If below this, lime should be applied post ploughing and worked into the seedbed.
