美国波多黎各大学在甘蔗地上试用水泥窖灰,获得增产。据试验,亩施166.7—2,666.7斤熟石灰(占三分之一)和水泥窑灰(占三分之二)混合肥料,甘蔗增产48％。水泥窑灰合钙量相当于48.51％的氧化钙和0.8％的氧化镁,或88.62％的碳酸钙;含钾2.19％,硫1.04％。美国路易斯安那州曾在粉粘壤土和粉壤土上进行了试验。每亩施水泥窑灰667斤。头茬亩施氮肥18斤,后两茬均施24斤。试验结果表明,由于施用水泥窑灰,粉粘壤土地平均每亩增产567斤,多产糖38.5
The University of Puerto Rico experimented with cement pit ash in sugarcane fields to gain production. According to the test, 166.7-2,666.7 kg of Mushi were slaked lime (one third) and cement kiln dust (two thirds) was mixed with fertilizer, and the yield of sugarcane increased by 48%. The ash content of cement kiln is equivalent to 48.51% of calcium oxide and 0.8% of magnesium oxide, or 88.62% of calcium carbonate; 2.19% of potassium and 1.04% of sulfur. Louisiana, USA, was tested on silty clay soil and silt soil. Per kilogram of cement kiln gray 667 kg. Head stubble acres of nitrogen fertilizer 18 pounds, after two stubble are applied 24 pounds. Test results show that, due to the application of cement kiln dust, pink clay soil yield 567 kg per mu, prolific sugar 38.5
