PowerPoint Presentation:

Sustainable Agriculture Site specific management Precision Agriculture Enhances environmental quality and the resource base in which agriculture depends; provides for basic human food and fiber needs; is economically viable; and enhances the quality of life for farmers and the society as a whole.’’(American Society of Agronomy (1989) Site specific management is the concept of doing the right thing at the right time in the right place. Information and technology based farm management system to identify, analyze and manage variability within fields for optimum profitability, sustainability and protection of land resources

PowerPoint Presentation:

Precision Agriculture is an environment friendly system solution that optimizes product quality and quantity while minimising cost, human intervention and the variation caused by unpredictable nature.

Encompassing variability is the key to PA:

Encompassing variability is the key to PA Variability: Yield variability Field variability Soil variability Crop variability Management variability Anomalous factors

Managing variability:

Managing variability Map based approach: Use of GIS and Remote sensing technology to generate high resolution raster layers which include yield maps, soil layers, topographic layers ect . Sensor based approach: It is used to generate real time data of the plant and soil properties which is fed to variable rate applicators.

Types of sensors used:

Types of sensors used Yield sensors: Grain yields are measured using four types of yield sensors-impact or mass flow sensors, weight-based sensors, optical yield sensors, and gamma ray sensors. Field sensors: This system allows users to record visual observations on crop growth, weeds, diseases, or other anomalies. Soil sensors: A near infrared (NIR) soil sensor measured soil spectral reflectance within the waveband of 1600–2600 nm to predict soil organic matter and moisture contents of surface and subsurface soils. Crop sensors: A field spectral-imaging system

Variable Rate application: N fertilizer and fungisides Source: (2007 )

PowerPoint Presentation:

Yare N-Sensor ALS This sensor system 1) scans the crops roughly 5 to 6 metres left and right of the tractor lane, records the light reflection of the plants as an indicator of their current nitrogen uptake, 2) translates the measured data (by using a special software) into fertilisation recommendations, which then 3) are used by the applicator to vary the actually needed amount of fertiliser spread.

Benefits of PA:

Benefits of PA Reduce ecological footprint Reduce input cost Sustained output Better pest and pathogen management Reduce pest resistance

Bottlenecks of PA:

Bottlenecks of PA Economically unfeasible for may countries Skilled manpower Proper decision-support systems for implementing precision decisions Insufficient recognition of temporal variation Product tracking Environmental auditing
