Analysis of Nutrient Content in Soil of Sugarcane Field at Jinguang Farm
摘要
Abstract
The present study was carried out to test 1200 soil samples from sugar cane field at Jinguang farm. The pH values of 70.9%soil samples were not lower than 5.5 with an average of 5.19. The average content of organic substances was 21.34 g/kg, and 68.25%soil samples were at moderate level. For total nitrogen content, 88.72%soil samples were at or higher than moderate level. For the content of available phosphorus, available potassium and exchangeable calcium, 50.46%, 50.53% and 53.18% of soil samples were at moderate level, respectively. For the content of exchangeable magnesium, 60.78% soil samples were at low level. It was abundant for the content of available sulfur. In addition, the correlation between the yield of sugarcane and the nutrient content in soil was analyzed.关键词
