Benefits of Soil Sampling

For many farmers the grazing season has ended and most are now in ‘winter mode’. The next grazing season is only around the corner however so you should be making plans as to how you are going to get the most out of your grass swards for 2024. A big consideration in regard to the productivity of these swards is the fertility of the soil which the grass is growing on. Winter is an ideal time to get the soil tested to determine the level of phosphorus and potash in the soil as well as the amount of lime that is required which will be determined by the pH of the soil. Many farmers are once again realising the value of lime with its usage having increased significantly in recent years. Lime acts as a soil conditioner, removing the acidity and improving the biological activity in the soil as well as releasing previously ‘locked up’ nutrients which in turn will feed the grass plant. Soils with adequate fertility will grow more grass even where chemical nitrogen usage has being reduced. For famers who have no soil samples taken within the last four years, their soil is seen as having an adequate level of phosphorus by the Department of Agriculture. This will limit the amount of chemical phosphorus these farmers can apply. Through the Department of Agriculture Fertiliser database, a record of all fertiliser a farmer purchases will be available. A farmer may unwittingly apply too much chemical phosphorus in the absence of soil samples unless they have their research done. Many ACRES participants will take soil samples soon as part of their ACRES requirements. It is important to take note of these results and in consultation with your advisor, plan your fertiliser accordingly. Look after the soil and it will look after you.
