An investigation on the nutrient and material effects of bark in komatsuna and tomato growing tests by using pots to determine the optimum mixed combination ()
ABSTRACT
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.
