Abstract: To investigate the response of soil management and cropping practice on infiltration, a field experiment was conducted under natural environment on Nitisol of Pawi area. Eight treatments combining two soil management methods (Zero tillage and conventional tillage) and four crop covers (continuous maize, continuous soya bean, rotated maize, and maize soya bean intercrop) were laid out on permanent plots in a randomized complete block design (RCBD) with three replications. The results showed that soil management and crop cover significantly affect both the capacity and rate of infiltration. Relative to conventionally tilled continuous maize, zero tilled maize soya bean intercrop improved infiltration rate and infiltration by 164.6% and 148%, respectively. While maize rotation with zero tillage, maize soya bean intercropping with conventional tillage and maize with zero tillage methods improve infiltration rate by 117.8%, 105.8%, 108%, respectively. The soil management and crop cover practices such as maize with zero tillage, maize soya bean intercrop with zero tillage, rotated maize with conventional tillage, maize soya bean intercrop with conventional tillage, soya bean with zero tillage and rotated maize with zero tillage increased soil water storage in the order of 65mm, 41mm, 41mm, 35mm, 15mm and 13mm. Generally, zero tillage with greater cover is an appropriate method to improve infiltration and soil water storage.

Abstract: This manuscript analyses the risk management in the oil and gas industries. The manuscript discusses risk management in the consideration of large uncertainties in addition the utilization of adaptive risk management in various conditions. This type of management depends on the certainty that a better choice cannot be made, on the contrary, a few choices must be powerfully followed in order to obtain data and information on the implications of different strategies. Henceforth, the safety in addition risk of management in gas and oil efforts is a basic need. The risk management strategies should be analyzed to avoid the risks happen in the oil and gas industries. Mostly, risks are happened in the oil and gas industries with the human error, natural accidents. In the manuscript, we focus on a case from the oil and gas sector, the primary thing is to gain experience on how the management can carry out risk management while focusing on major hazard information and vulnerability areas. Of late, a few authors have competed to obtain some new types of risk perspectives, including information on how vulnerabilities and dangers are perceived, and the assessment that this article uses these perspectives as a reason for conversation.
