“…In the second cropping, despite using herbicide, two times of weeding were needed due to the weed proliferating in spring. Miura et al (2008) 13 also showed weed biomass was higher in spring than fall in adjacent experimental plots. In the third cropping, herbicide using, weeding practice and low weed growth rate would help achieve high NT treatment productivity.…”

“…In the third cropping, herbicide using, weeding practice and low weed growth rate would help achieve high NT treatment productivity. Miura et al (2008) 13 showed that the yield of Chinese cabbage under no-tillage treatment was lower than that under conventional tillage. Our data were consistent with their study, and showed that reduced tillage helped to avoid a reduction in the Chinese cabbage yield.…”

“…The soil was a humus-rich volcanic ash (an Umbric Andosol, according to the FAO classification; 55% sand, 26% silt and 20% clay) 13 . The air temperature and precipitation were monitored near the experimental field.…”

“…Kaneda et al (2009) 9 showed that removing surface litter caused a reduction in the surface cast production of the same species, meaning decreasing surface litter by tillage would induce low surface cast production due to decreasing earthworm casting activity or escaping from tillage plots in this experiment. In addition to mechanical damage to earthworms, the elimination of organic matter from the soil surface and disturbance 13 showed that surface cast production under conventional tillage was lower than under a no-tillage system. Results in this study were consistent with previous research, and revealed that soil surface cast production in reduced tillage treatments was lower than that in the NT treatment, but exceeded that in the CT treatment.…”

Soil aggregation by earthworms is important for sustainable agriculture because soil aggregates are highly permeable and retain water. Casts are a soil aggregate and indicator of earthworm activity. The effects of reduced tillage using a rotary tiller on earthworm cast productivity and yield of Chinese cabbage were investigated in volcanic-ash soil. Five tillage practices were investigated; conventional tillage (CT), no tillage (NT), and three reduced tillage practices: shallow tillage, row tillage, and shallow row tillage respectively. Cast production of Pheretima (Amynthas) carnosa, the species which dominated the study site, and yields of Chinese cabbages were measured during three crop seasons. Crop yield under the NT treatment was lower than that under the CT treatment (p<0.05) in fall 2004, while in spring 2005 Chinese cabbage under NT treatment did not head out. Yields under reduced tillage treatments tended to decrease in spring 2005, but were similar to those under CT treatment in the other two cropping seasons. Under CT treatment, the surface cast production was almost zero. Cast production under reduced tillage exceeded that under CT treatment, but was lower than that under NT treatment. Accordingly, reduced tillage can combine the ability to preserve aggregate formation by earthworms while also preventing any decline in Chinese cabbage production yield in the cropping system studied.

“…However, white clover decomposes quickly in soil. Miura et al (2008) investigated white clover mass loss near our plot and showed that 75% of the mass was lost after 27 d by burying it in humic Andosol. Thus, the rapid decomposition of white clover is likely the main reason why we did not detect any effects of clover mixing on total soil C in CT.…”

Living mulch is a type of sustainable farming system that consists of cover crops planted either before or with a main crop; a living mulch is maintained as a living ground cover throughout the growing season of the main crop. Microbial biomass and abundance of mesofauna (microarthropods and enchytraeids) are important soil biological parameters in relation to soil function, plant productivity, and nutrient cycling; however, the effects of living mulch on these parameters are not fully understood. In this study we examined the effects of living mulch treatment with nitrogen fertilizer (0, 40, 160, or 200 kg ha À1 ) on the abundance of soil microarthropods (Oribatida, Mesostigmata, Prostigmata, and Collembola) and the effects of living mulch treatment on the dynamics of the soil biota (mesofauna, microarthropods, enchytraeids, and microbial biomass nitrogen) from spring to autumn. Our results showed that living mulch treatment significantly (p < 0.05) increased the grain weight of the main crop in both experiments. Generally, living mulch treatment had a positive effect on the abundance of mesofauna and microbial biomass nitrogen, despite pesticide usage. Nitrogen levels did not affect the number of microarthropods. The litter layer in living mulch significantly (p < 0.05) enhanced microbial biomass nitrogen and the abundance of Oribatida, Prostigmata, and Collembola. We conclude that living mulch enhances mesofaunal abundance and microbial biomass nitrogen and that the production of a litter layer by living mulch is one of the major mechanisms for this enhancement.
