Criteria for Selecting Optimal Nitrogen Fertilizer Rates for Precision Agriculture

Development of an optimal model of criteria for selecting the presidents of the universities in Iran

Objective: The selection of the presidents of the universities, considering the role of the university in today's knowledge-based world, becomes more complex every year. It is therefore expected that a careful and informed process be used when appointing or selecting such a manager. Considering the importance of selecting university presidents based on appropriate criteria, the present study wa...

Criteria of selecting satellite data for studying land resources

In recent years, acquiring information of remote sensing data, especially satellite data has excessively increased and several methods are presented in order to improve the quality of remote sensing studies in earth sciences. It is possible to manage many projects and provide different types of thematic maps in a short period of time, and a low cost by utilizing satellite data and GIS method. R...

Robots for Precision Agriculture

Indian agriculture, even after the Green Revolution, is not as productive as it could potentially be. It calls for a second Green Revolution – one of „precision agriculture‟, where cutting-edge technology is used to maximize production with minimum input costs and resources. In this paper we present a multi-purpose agricultural robot to implement precision irrigation, fertilizer addition and de...

Optimal fertilizer nitrogen rates and yield-scaled global warming potential in drill seeded rice.

Drill seeded rice ( L.) is the dominant rice cultivation practice in the United States. Although drill seeded systems can lead to significant CH and NO emissions due to anaerobic and aerobic soil conditions, the relationship between high-yielding management practices, particularly fertilizer N management, and total global warming potential (GWP) remains unclear. We conducted three field experim...
