Abstract/Contents:"An improved management of phosphorus (P) is crucial for increasing crop production and improving environmental quality of acid infertile soils. Laboratory analyses and greenhouse experiments were conducted to evaluate effects of phosphate rock (PR), coal combustion by-product (BP), limestone, and cellulose application on the relationship between soil test P and crop growth in acidic soil. Application of PR, BP, limestone, and cellulose increased soil pH, exchangeable calcium (Ca) and magnesium (Mg), and extractable P, and decreased free aluminum (Al) ion in the acid soil. Addition of BP or limestone increased P availability efficiency [PAE, mg dry matter yield (DMY) of plant per mg soil extractable P by Olsen-P procedure] and P utilization efficiency (PUE, mg DMY of plant per mg P in the plant). There was significant positive correlation between the PAE and BP rates applied alone (r²=0.979, p<0.01) or with either PR (r²=0.972, p<0.01) or PR plus cellulose (r²=0.985, p<0.01). The PUE of ryegrass was significantly correlated with BP rates alone (r²=0.957, p<0.01) or with either PR (r²=0.906, p<0.01) or PR plus limestone (r²=0.699). The increase in PAE and PUE of ryegrass caused by BP and limestone reflected more plant root growth from increased availability of Ca and Mg and higher soil pH."
