Please find enclosed a summary of results obtained from a range of field trials. These include a study of some techniques to replace undesirable cultivars of subterranean clover; the competitive ability of some subterranean clovers; the evaluation of the sub clover cultivars, Dinninup 3, Midland B,some members of subspeciesYanninicum, the medic cultivars Cyfield and Tornafield; and the preliminary results from an exotic pasture species introduction trial at Shark Bay. In most cases complete results have been or will be circulated in report form.

Medium Rainfall Zone Trials Eleven replications of the basic rate of P, rate of SO4-S and S experiments were maintained during 1970 in the 20in - 30 in. rainfall zone. Soil types examined were the very gravelly soils (5 reps, 4 sites), sands or loamy sands over gravel or clay (3 sites) and sandplain soils (3 reps, 2 sites). In all cases except one, fertiliser history was not reliable, but in every case well over one ton of super had been applied. over a period of over 15 years.

Anhydrous ammonia, as the name infers, is pure ammonia, It is kept in a liquid form under pressure and must therefore be stored in special vessels. When pressure is released it changes to gaseous form. Anhydrous ammonia is the most concentrated form of nitrogen fertiliser available. It has 82% nitrogen compared to 46% for urea, the most concentrated solid form of nitrogen fertilisers.

SUBTERRANEAN CLOVER INOCULATION EXPERIMENTS Badgingarra and Newdegate Comparisons between Rhizobium trifolii strain WU290 and possible replacement strains were continued. The work was conducted for the following reasons 1. The need for information on "back-up" strains particularly since the inoculant manufacturers had experienced difficulty in producing high-count peat cultures of WU290. 2. Strain CC2480a had proved very satisfactory in the Eastern States. Although it did not show up to advantage under our conditions in 1968,further testing was indicated. 3. The need for information on inoculation needs on old land.
