In oil palm cultivation, the continuous removal of nutrients through Fresh Fruit Bunches harvest results in declining soil fertility. This causes a serious decrease in yield per unit area narrowing the financial base of the oil palm farmer/development estates. Phosphorus is the second most important nutrient in oil palm nutrition. The sustainability of added phosphorus to weathered soils for tree nutrition partially depends on the types of fertilizer material used. The most common fertilizers are super phosphates in the tropics, and phosphate rocks in the Far East (Malaysia and Indonesia). The high cost of soluble phosphate fertilizer has generated considerable interest in the utilization of phosphate rock in oil palm cultivation. This book assesses the fertilization effect of phosphate rock on growth, development and yield of oil palm in Ghana. It also looks at the influence of phosphate rock on soil microbial activity under oil palm as well as the influence of phosphate rock on soil nutrient dynamics. The economic benefit of using phosphate rock under oil palm is also examined. The book is written to serve as a reference document for all stakeholders in the oil palm industry.
i). Leptospirosis, also known as Weil's disease is a zoonotic infection, caused by pathogenic spirochete bacteria of the genus leptospira that is transmitted from animals to human. Human infection is transmitted via direct contact with the bacteria through contaminated urine, blood, or infected tissue from animal reservoirs especially rodents (and rats) or indirectly from contaminated water and soil. In this research, 478 environmental samplings of water and soils were analysed from several recreational water spots in State of Johor, Malaysia from January 2014-March 2018 to detect the presence of pathogenic leptospira. Rat study was also done in Gunung Ledang Waterfall Resort, Tangkak, Johor, Malaysia in 2014 and 2017. ii). Typhoid fever is a food and waterborne disease, caused by gram negative bacteria, Salmonella typhi. In Malaysia, the incidence rate is below 1 per 100,000 populations, but endemic in some areas, particularly in East Malaysia and East Coast of Peninsular Malaysia. The source of infection was seldom found. The typhoid outbreak in Segamat, Johor, Malaysia in Mac 2018-May 2018 highlighted the management and investigations of the outbreak.
Malaysia produces about 5 million metric tonnes of sewage sludge annually.The quantity of sludge is expected to increase every year and directly proportional to the increase in municipal wastewater that had to be treated.The use of sewage sludge as a fertilizer has not been practiced nor publicly accepted in Malaysia.Nevertheless, the application of sewage sludge to agricultural land is generally the most economical means of waste disposal and also provides an opportunity to recycle beneficial plant nutrients to soil for crop production.However, sewage sludge also contains varying amounts of heavy metals which may pose a hazard of metal toxicity to crops and the consumer of these crops.At present there are no guidelines or policies on land application of sewage sludge in Malaysia.Studies need to be conducted so that regulations and policies developed are based on scientific data. Therefore,this book provides an assessment on the feasibility of using sewage sludge as a fertilizer on agricultural land in Malaysia.Thus,the crop response, uptake of heavy metals by crops and the fate of these heavy metals in soils have been investigated and discussed in various chapters of this book.
