Application of Bicarbonate to High-Phosphorus Soils to Increase Plant-Available Phosphorus

Vegetable growers in the northeastern United States often have soils with P levels so high that fertilizer applications have environmentally detrimental effects. However, growers raise crops that require P fertilizer in cool soils regardless of soil P levels. A method to increase bioavailable P to...

Raw Materials Used for Composting

Large amounts of agricultural by-products or livestock wastes are produced annually in Taiwan. Hogs excrete about 73 x 104 mt/year; chickens, 186 x 104 mt/year; and cattle, 30 x 104 mt/year. Annually, by-products from bagasse amount to 31 x 104 mt; straw, 31 x 104 mt; rice husk, 1.7 x 104 mt; bark...
