To answer the question: Can incorporation of lime speed up yield response?
Key messages
Incorporation of lime has not shown a yield response above that of surface applied lime in the first year with wheat or canola in a wet year.
Acid layers exist within soils and are mainly confined within the topsoil on basalt soils and can extend deeper in other soil types.
Sampling soil in 5 cm increments is useful for identifying exactly where acidity is the profile so that lime can be potentially incorporated within the acid area.
Surface-applied lime takes time to move down the soil profile and ameliorate acidity.
To minimise yield losses where acidity issues exist (pH less than 5.0), sow acid tolerant cereals (eg. wheat) following liming or look to incorporate lime.
