To determine which fertilizer is best used for a particular soil when growing different crops, it is necessary to become familiar with the main types of lime fertilizers, their characteristics and application features.

Types of lime fertilizers

Lime fertilizers are divided into three groups depending on what natural rock they were extracted from:

  • solid( rocks that require additional grinding or roasting), such as limestone, chalk and dolomite;
  • soft( do not require grinding) - marl, natural dolomite flour, calcareous tuff, lake lime;
  • industrial waste, which includes a lot of lime( cement dust, shale and peat ash, belite flour, defecation mud).
