A Look at What’s in Store for Business and Workers : It won’t be dull, that’s for sure. The new year will see dramatic changes for U.S. industry and the American worker. Business writers at The Times polled experts on what is likely to happen in 1989. Here is their report. : AGRICULTURE

Most of agriculture’s bright news in the new year will likely come from continued improvement in export sales. World prices are rising, and volume of such basic commodities as corn and soybeans, reduced by last summer’s drought, is expected to shrink 8%. Farm exports are expected to grow about $1 billion to $36.5 billion, the U.S. Department of Agriculture estimated.

California exports are now beginning to approach the record year of 1982, when sales approached $4.2 billion. The state’s highly diversified farm economy produced $3.34 billion in export sales in 1987, and 1988 may have boosted that nearer $4 billion. More than half of the sales went to Pacific Basin nations, chiefly Japan, which alone accounted for 29% of exports--the same as the entire European Community. Exports now account for about 20% of the state’s total crop sales of about $16 billion.

Food shoppers will likely find prices rising 3% to 5% due to higher prices for drought-damaged crops and products that depend on them--chiefly, cereals and bakery products, vegetable oils, fruit and vegetables. Meat supplies will be ample, the USDA said.
