Analysis: 16-0-0. Hi Yield Nitrate of Soda contains nitrogen which is a major player in the growth of stems and leaves. Too much causes delayed flowering and fruiting and too little can cause stunted growth. Suspect nitrogen deficiency when new growth is pale, yellowish, or otherwise weak. If your soil is deficient in nitrogen, the only rock mineral fertilizer to use is nitrate of soda (16-0-0), which can also be called sodium nitrate. The mineral nitrogen, mined from the Atacama Desert in Chile, is almost immediately available to plant roots. It is short-lived in soil, so it is best applied just before planting time. Apply 4 pounds per 1,000 square feet. Nitrate of soda is not recommended in the low-rainfall regions of the western U.S., where soil is normally alkaline and some soils may contain excess sodium. The fertilizer increases both sodium and soil pH - 1 pound of sodium nitrate raises pH about as much as 3 pounds of lime would. Hi-Yield Nitrate of Soda is a fast acting, non-acid forming source of nitrogen when growth and color are needed quickly.
