  • This product will affect the ph of the soil.
  • Calcium sulfate, the main ingredient, dissolves well in water and is efficiently absorbed by crops.
  • Through the synergistic effect of calcium and sulfur, soil quality will be recovered, the crop will grow healthily, and it will be effective in improving quality and yield.
  • Helping root growth
  • Healthy growth with cellular strengthening of crop plants
Especially recommended crops

Darwin 2000 application example

Test sample:
Test location:
Mr. K’s farm in Minamimaki village, Nagano prefecture
Sowing date:
Number of plug holes:
200 holes
Survey method:
Seedlings are cultivated in an area with 500g of Darwin 2000 mixed into 40 liters of soil, and another area using conventional method, and compared the weight and tension of roots.
Survey result:
10 stubs were taken randomly from each area
Survey date: April 4th, 2007

There is increased root weight in the area with 500g of Darwin 2000 mixed
into 40 liters of soil before planting (roughly 18% increase compared to the
conventional area) and the root tension is also improved.
