In the early 1980s the Harrow Research Station developed a peat-bag system for greenhouse tomato production. The recommendations for the peat-based growth medium and the corresponding fertigation schedule are presented in Tables 15 and 16, respectively

Table 15 Peat-bag growth medium recommended for tomatoes

  1. 0 (0.17 m3) bags of peat moss (57% of total volume 1
  2. 0 (0.11 m3,7 kg) bags of vermiculite (25% of total volumel A
  3. 0 (0.11 m3,7 kg) bags of perlite (18% of total volumel
  4. 0 kg limestone (pulverized FF) 4.0 kg ground limestone (dolomitic)
  5. 5 kg ground superphosphate (20% phosphorus1 B
  6. 0 kg potassium sulfate
  7. 0 g fritted trace elements (FTE302)

2.0 kg 18-6-12 slow release (9-month) fertilizer

35.0 g Borax (15% boron)

35.0 g chelated iron (iron EDTA, 13% iron)
