Description
More than twelve hundred public pastures have been established since I 960's in Japan, totalling some 0.6 mil. ha located in highland areas to raise cattle. Now most of them need renovation because of low productivity. This is due to mismanagement, insect attack, weed invasion and under-utilization, etc. But complete tilling is not advocated on slope sites as it is in danger of soil erosion after reseeding. Several methods hve been proposed to renovate the deteriorated pastures, e.g. usmg herbicides (Blackmore, 1965), burning (Sawada et al., 1986), surface tilling (White, 1973), surface sowing with phosphate and lime (Cullen, 1966) and seed coating (Lowther, 1987; Norris, 1970; Hirota, 1975). Coating seeds has been developed to ensure quick strike of sown species by promoting moisture absorption of seeds, supplying nutrients for seedling growth to obtain safer establishment. Broadcasting the coated seeds into existing old pastures in the course of renovation is being examined extensively in Japan. The authors have improved seed pellets with ten forage species both in single coating and granulating.
