Influences of soil creatures toward aboveground Arthropods in environmentally friendly rice field

Abstract

Environmentally friendly farming is the most encouraging approach to beat the negative impacts of conventional farming on the ecosystem. To determine the effect of different histories of environmentally friendly rice fields on the interaction between soil creatures and biodiversity of aboveground arthropods, the researchers conducted studies in 5 and 20 years old of environmentally friendly rice fields. The investigation was conducted to find out the impacts of soil creatures on the number of aboveground arthropods by estimating the activity of soil creatures, nutrient contents, and abundance of arthropods. The research was hypothesized that long histories of living matters in the environmentally friendly rice field are supposed to rise soil microbial denitrification and N immobilization, adequately increment the plant N contents and arthropods abundance. The results showed that 20 years of environmentally friendly rice fields improved the abundance of soil creatures, biomass of soil microbial C and N, soil nutrition, and these effects indirectly improved the abundance of aboveground arthropods. This investigation recommends that environmentally friendly rice fields improve the interactions among soil creatures and the aboveground ecological community accordingly may accomplish supportability of the rice field framework.
