    2021-5-1 · SynopsisAfter 26 and 27 years at the Campbellsville and Greenville experiment fields, respectively, yields of corn, wheat, and hay were generally maintained or increased on superphosphate, rock phosphate, and rock phosphate residual plots, but decreased on superphosphate residual plots. Initial availability of rock phosphate tended to be lower than

  • Residual Effect of Rock Phosphate, Farmyard Manure

    The residual effect of rock phosphate along with soil incorporated FYM and EM was showed significant variation in plant height (Table 2). The treatment of EM 1 produced tallest plants of (90.04 cm) height. The lowest value of Plant height (84.46 cm) was recorded in control treatment.

    2003-4-15 · The residual effect of P rock phosphate was highly beneficial to grain yield and soil available P content. After three years, results indicate sustainable residual response of NERICAs to rock P. Rock phosphate can also be used as an alternative to improve Alfisol and Ultisols available P content in the humid forest zone.
