新西兰Massey土壤科学部门的一研究小组,试验了两种全新的磷肥:Chatham Rise磷灰岩和秘鲁Sechura磷酸盐矿石;并认为这两种磷肥大有发展前途。该研究小组的Paul Gregg博士、Keith Syers教授和Lance Currie提出了一篇长达46页的报告,对在草地直接施用这些磷酸盐矿石与通常用的过磷酸钙进行了比较。就牧草的产量和磷的吸收而言,在第一 A team from the Massey Soil Science Division in New Zealand tested two new phosphate fertilizers: the Chatham Rise Phosphorite and the Peruvian Sechura phosphate ore; and sees both types of P fertilizers as promising. The research team’s Dr. Paul Gregg, Professor Keith Syers and Lance Currie presented a 46-page report comparing the use of these phosphate ores directly to grassland with the commonly used superphosphate. In terms of pasture production and phosphorus uptake, in the first place
