The effects of bark
on komatsuna (Japanese spinach) and tomato were investigated by changing the
nitrogen content of chemical fertilizers and bark mixing ratio. Mixing 25 and
50% of bark with soil improved komatsuna growth, and also exceeded the growth
rates obtained by using chemical fertilizers. However, komatsuna could not grow
in 100% bark alone, with excessive amounts of bark majorly inhibiting komatsuna
growth. The aeration of bark also did not enhance komatsuna growth. The
nitrogen content and bark-mixing ratio had a much lower impact on tomato growth
compared to komatsuna. In comparison, aerated bark was more effective in
enhancing tomato growth compared to komatsuna growth.
