Lucerne requires deep, well-drained soils (sands to moderately heavy clays) with a slightly acid to alkaline pH. It is intolerant of high levels of exchangeable aluminium. PGG Wrightson Seeds recommend a crop rotation with a lucerne crop as this helps to lower the risk of root disease becoming a problem. This can be achieved by sowing a forage crop such as; winter sown Cooee® Oats/Southern Green Ryecorn or summer planting of sorghum/millet. This method also assists with weed suppression prior to final cultivation. Take a soil sample 6-8 months prior to planting as this will allow time for any soil pH or nutrient corrections to occur. It is important to have a well prepared seedbed, free of any weeds, prior to planting. We recommend the use of Superstrike™ coated seed which contains the correct rhizobia and insecticide to assist maximise seedling establishment and plant development. Weed infestation early in the life of lucerne stands can limit yield and hay quality. In general weed infestation is greater in the warmer months so any sowings in spring will require careful management including potential herbicide applications. Autumn sowing has less weed risk potential, however, herbicide applications may be necessary in certain circumstances.
