Acid soils stop plants and roots from growing properly, and plants cannot take up as much nutrients as they need from the soil. Crop yields and farmer profits are lower than they could be
Many soils in Fiji are naturally acidic, and others are acidic after years of farming
Before planting you should know how acidic your soil is, by measuring its pH level. pH levels are from 0-14. From 7-0 pH goes from neutral to very acidic. From 7-14 pH goes from neutral to very alkaline. Most plants grow well in pH between 5.0 and 7.0
Before planting you should correct the soil pH level to a level suitable for your type of crop. This first application of lime is called remedial liming and will need a large amount of lime. You should see a big improvement in crop by the first harvest after lime is applied
After you’ve got the pH correct, you should manage your fields so that pH does not fall again and cause problems. These applications will need smaller amounts applied before each crop is planted
Some examples of application rates are found below. For information on application rates for the crop you are planting, based on your farm’s pH level, please contact your local Ministry of Agriculture Extension Officer.
