Product Description

Humistart is a soil conditioner proven to increase microbial activity, provide labile calcium, and improve breakdown of manure and (or) stubble into plant available nutrients. As a homogeneous granule, it supplies several key nutrients, such as nitrogen, calcium, sulfur, magnesium, and trace amounts of boron, iron, and zinc. Humistart works well on manured fields, orchards, vineyards, vegetables, fruits, and in both no-till and conventional tillage. It can be used alone or blended with other granular fertilizers.

Key Benefits

  • Calcimer provides labile calcium that helps improve soil structure and feeds the crop
  • Delivers other critical micronutrients in a homogeneous granule
  • Humistim complex (our patented soil amendment) increases microbial breakdown of stubble or manure into plant-available nutrients


Broad acre application in no-till or manured fields will often call for 100 to 200 lbs/ac. Tree fruit and vegetable production will normally require 200 to 400 lbs/ac to more intensively increase solublecalcium. Humistart can be blended with fertilizers or applied alone. Please refer to soil tests and the advice of your Timac Agro sales representative for specific recommendations.
