Contamination level 3 (10 000–25 000 Bq kg -1 ), which indicated a need to remove topsoil, was distributed in only the EA-20km and DEA, with more than half (55 percent) in the EA-20km. Eighty percent of fields with contamination level 2 (5 000–10 000 Bq kg-1) were distributed in the evacuation zone, with the remaining 20 percent distributed in the non-evacuation zone in Fukushima Prefecture. Paddy fields with contamination level 2 (2 100 ha) have three options for decontamination: topsoil removal, fine-textured topsoil removal using water, and topsoil burying. Upland fields, orchards, and meadows that are at contamination level 2 (1 200 ha) have two options for decontamination: topsoil removal and topsoil burying. Nutrient imbalance The soil surface nitrogen (N) and phosphate (P) balance in Japanese arable land has been improving (Mishima, Endo and Kohyama, 2010a; 2010b). These values serve as the index of the impact of arable land on the environment and of the farm-gate balance of nutrients. The soil surface N (and P) balance is defined as the total N (P) input (N kg ha -1 ) minus the total N (P) output (N kg ha -1 ). Chemical fertilizer application in Japan declined continuously during the period from 1985 to 2005. The application rate of livestock manure also peaked in 1990 and declined thereafter. Crop production, however, remained constant during this period. Between 1985 and 2005, the surplus N and P (positive value of soil surface N balance) declined from 89.9 to 49.3 kg N ha -1 and from 153 to 105 kg P ha -1 respectively (Mishima, Endo and Kohyama, 2010a; 2010b). However, this trend was not consistent at the regional level because organic amendment applications were largely related to the availability and movement of livestock excreta (Mishima, Endo and Kohyama, 2010a) and to soil type (Leon et al., 2012). High surplus P and low crop P uptake compared with N, P input for crop production could be reduced. This limited negative environmental effects such as eutrophication of soil and water and conserved limited P resources.

The Basic Soil-Environmental Monitoring Project found excess soil Ca in paddy fields, upland fields and orchards during 1979-1998 (MAFF, 2008), but also a gradual increase in soil Mg deficit over the same period. Thus the balance of Ca and Mg has been deteriorating in Japanese arable land. In addition, the soil pH of paddy fields gradually decreased from 5.8 to 5.7 1979-1998 (MAFF, 2008). Soil erosion Spatial estimation of soil loss from arable land at national scale was carried out using the Universal Soil Loss Equation (USLE) and environmental inventories (Kohyama et al., 2012). Hourly rainfall and runoff factors (R: resolution 1 km) were calculated by the amount of precipitation analysed by radar-AMeDAS. Topographic factors (LS) are shown in Figure 10.7, calculated using a digital elevation model (resolution 50 m) and ALOS satellite imagery. The soil erodibility factor (K) of arable land was calculated using the physico-chemical soil properties (soil texture, soil organic matter content, etc.) as measured in the Basic Soil-Environmental Monitoring Project (Taniyama, 2003). The K factor of arable land was determined by soil series groups. The K factor was relatively higher in clayey lowland soil group than in humic Andosol groups. The cover and management factor (C) of each crop was determined by Taniyama (2003), and was delineated using the agroenvironmental census data map (Kohyama et al., 2003). 0-‐4 5-‐9 10-‐14 15-‐19 20-‐24 25-‐29 30-‐34 35-‐40 40-‐ 0-‐20 20-‐40 40-‐60 60-‐ Topographic factor (LS) Soil erodibility factor (LS; kg h MJ -‐1 mm -‐1 ) 0-‐0.1 0.1-‐0.2 0.2-‐0.3 0.3-‐ I II III IV V VI Non-‐arable land Cover and management factor (C) ClassificaBon of esBmated soil loss venerdì 20 novembre 15 Figure 10.7 Distribution map of the parameters of USLE and classification of estimated soil loss.
