Pre-construction treatment of soil-media for golf greens

Basamid G may be used to fumigate soil as pre-construction treatment for golf greens.  

The following procedure is a guideline for pre-construction soil fumigation done off site or at the construction site.

Before blending carefully shred all peat, other organic or native soil because a uniform particle size of the medium is essential for quality turf.
Blend sand, peat, organic or native soil into a homogenous mix according to USGA or national standards.

Depending on target problems measure out 8-10 ounces (230-285 grams) of Basamid G per ton of finished mix. Blend the Basamid G with the plant nutrients and other soil additives. Add the mixture to the soil medium during the last blending operation.

  Off site: Build a soil heap of max. 6 feet (2 meters) height. Irrigate while building the heap slowly to moisten the soil not to saturate it. Then cover the heap with plastic sheeting. When fumigation is complete (temperature and time) the tarp is removed and the soil thoroughly worked and aerated. A germination test should be carried out before using the soil media. If the soil media is not intended for immediate use keep plastic tarp on to avoid the infestation with weed seeds or fungi by air contamination.
  Onsite: After final quality control deliver the finished mix to the construction site and shape according the architect's design.
  When the green is completed, measure soil temperature at 4 inches (10 cm) and record.
  In order to activate Basamid G, irrigate until the moisture has reached the bottom of the media layer, using fine nozzles e.g. frost protection nozzles. To contain the fumigant activity cover with plastic tarp when irrigation is complete. If no plastic tarp is to be used roll the new green and provide a water seal by irrigating daily with a total of 0,25 inch (approx. 6 to 8 l/m2) water at several times for 4 to 5 days.
  Depending on soil temperature, remove tarp or stop irrigation and allow for a waiting period of 3 to 10 days.
  Carry out germination test. If the test shows harmful residues, leave the treated area for a further waiting period of 3 to 5 days and repeat the test.
  When germination test indicates the absence of harmful residues, proceed with seeding, sprigging, sodding or planting.
