Description
As part of a joint Chinese-Australian Project to promote livestock development, a farm site in the lower Chinese section of Red River Valley was chosen as an area to study techniques suited to meeting these objectives through establishing and utilizing legume based tropical pastures. Preliminary results of fertilizer trials at Daliuhu Farm show that sulphur deficiency is the main nutrient problem retarding the growth of siratro and stylo legumes. The application of as little as 5, but optimally between 10 and 20kg of sulphur as gypsum Sor elemental S seems to adequately meet their growth requirements. The apparent adequate phosphate status and low phosphate fixation properties of this soil seem unusual for tropical soils.
