...areas, still covered with ash and mud. Lupines are beginning to grow along erosion channels. Tiny fir trees, freed from competition with their fallen parents, are expected to take advantage of the extra sunlight and make a quick comeback. Scientists say that nutrients from the volcanic ash-such as phosphorus and potassium-could actually enhance their growth. As if to prove the point, some farm areas that were dusted with ash had record harvests of wheat and apples last year...
Workers covered the last puddles of leaked phosphorus trichloride with dirt last night, and officials said the area was out of immediate danger as evacuated residents began to return to their homes...
...secret of the leucaena's rapid growth is in its roots; they extend as deep as the tree is tall. That enables it to soak up nutrients below the reach of other plants. Growing on the leucaena roots are fungi called mycorrhizae that help by absorbing phosphorus compounds that cannot be used by most plants, and converting them into forms that can nourish the tree. Then too the steady dropping of leaves provides rich nutrition for other plants...
...most important omens for the future of the lakes is the sharp reduction in the amount of phosphorus dumped into them. A 1972 U.S.-Canadian agreement lowered the levels of phosphates that municipalities were allowed to dump into the water, and most towns along the shores and on rivers emptying into the lakes are well on their way toward meeting those requirements. The significant exception is the city of Detroit; it continues to dump three times the permissible levels into the Detroit River, which flows into the western end of Lake Erie. One of the largest sources of the harmful...
...polyester mesh vest, developed by Dr. Stanley Dudrick and his team at the University of Texas, has two breast pockets that hold plastic bags filled with Jason's food-a solution of amino acids, water, sugar, salt, potassium, magnesium, calcium, phosphorus, vitamins and trace elements. A battery-powered miniature pump zippered into another vest pocket propels the solution through a tube implanted in Jason's skin midway between his rib cage and navel. The tube runs up his chest to the base of his neck, where it threads into a vein leading to the superior vena cava...
