...expected to start soon on bringing water from the Yarkon-Negev pipeline to irrigate the first 2,500 acres of citrus-growing land in the Deir el Balah sector. In nearly every village, Israeli experts are handing out new strains of grain, instructing farmers in how to fertilize their soil and improve their scrawny breed of cattle...
When any kind of strontium gets into soil, it is taken up by plants as if it were calcium. Since plants do not like it as much as calcium, those grown in calcium-deficient soil generally contain more strontium 90 than plants that get plenty of calcium. It is not established, however, that all plants behave in this...
Most of the strontium 90 created by past bomb tests is still in the stratosphere or in the soil, but it will tend to move for years into human bones. If no more large tests are made, the Columbia men figure, the average human bone should contain, by 1970, about 1.3 micromicrocuries of strontium 90 per gram of calcium. This is eleven times the present amount...
...Columbia men are concerned about such individuals as the Vancouver man who have a lot more strontium 90 than the average, and about people who get most of their calcium from vegetables that were grown in calcium-deficient soil. Such people may come much closer to the "permissible" level. The permissible level itself is still considered debatable. It was derived principally from a small amount of experience with the cancer-causing effects of radium in the bones; at that time no strontium 90 existed in the world. When more is known, the permissible level for strontium 90 may have...
...also learned to bend with the political winds. He fought for passage of the 1954 farm law that substituted semiflexible price supports for the Democrats' rigid supports, but agreed to limit the range of flexibility so that actual supports did not drop much. He once considered the soil bank a Democratic gimcrack, now embraces it as a painless way to cut surpluses. And in the 1958 budget he asked for an unprecedented $4.9 billion for agriculture, the largest farm outlay in U.S. history. Benson's vigorous program to sell off surpluses at home and abroad has worked...
