Lime ensures the correct pH and the correct nutrient balance for grain and oil crops. Grains do best at a pH of 6.0–6.5. However, some grains may do well at a lower value. Liming can take place throughout the year, as long as spreading equipment can access the area. Ideally, you should lime after cultivating or on stubble before ploughing. The lime works fastest when it is worked into the soil. If the soil needs a large amount of lime, you should divide the amount in two, and spread it before and after ploughing.
Oil crops must have a pH of 6.0–6.5. If there is a high risk of club root, the pH should be even higher. It may be appropriate to lime up to a value of 7.0.
