Abstract

An incubation experiment was conducted to assess the storability of poultry droppings compost for effective utilization and field application. In general, the nutrient content of the compost will vary depending upon the quantity and nutrient content of the manure, age of the compost and the method of storage. In our present study, we found that the storage of poultry droppings under normal condition did not influence the pH of the compost in the first 30 days but a slight reduction in pH (0.1 to 0.2) was observed between 30^th day and 45^th day. The Electrical Conductivity (EC) of the stored compost was increased but the level of increase was not exceeded 0.02 dS m^-1. A slight increase in total nitrogen content was recorded during storage of poultry compost and this might be due to moisture loss and reduction in volume. A slight decrease in total phosphorus and total potassium was also recorded in the stored compost during 75^th and 90^th day of storage. The microbial population was high between 30th and 45th day of storage. Compost contained a relatively large amount of micro-organisms associated to organic nitrogen mineralization which might have altered the chemical properties. There was no much variation in the nutrient status of the compost during first 45 days of storage and hence the poultry compost can be applied to land within 45 days after its maturity to derive maximum benefits.

Abstract

An attempt has been made to know the quality and hydro geochemistry of ground water in the Perur taluk of Coimbatore district and to check whether the water contains arsenic. Ground water samples were collected from twenty four villages in Perur taluk. In each village two samples were collected from two different bore wells. The water samples were collected from the bore wells with the depth range from 200 ft to 800 ft. Chemical parameters namely, pH, electrical conductivity (EC), total dissolved solids (TDS), chlorides, hardness, iron, phosphates, nitrates, sulphates and arsenic were analyzed using standard protocol. The results were compared with water quality standards given by World Health Organization (WHO). The ground waters of eight locations namely Sundakkamuthur, Vedapatti, Komarapalayam, Madvarayapuram, Veera Keralam, Jagirnaicken palayam, Puluvapatti and Vadavalli are well within the water quality standards for drinking and irrigation purpose. Whereas the ground waters of remaining sixteen locations of Perur are not suitable for drinking but it can be used for irrigation purpose. With respect to arsenic poisoning, ground water samples of all the twenty four locations of Perur are well within the permissible limit.
