PRECISION AGRICULTURE

 

NEAR-INFRARED (NIR)

NIR scanners are useful in measuring different aspects of plant physiology that reflect the nutritional status of crops. NIR tools can provide information on the concentrations of major nutrients such as nitrogen, phosphorus, and potassium, by detecting chemical composition in leaves

MULTISPECTRAL

Multispectral sensors can be used to obtain the vigour index (NDVI) and filter the multispectral frequencies to create specific reports quickly. For instance, it is possible to classify vegetation, identify land use, and distinguish the vegetative vigour of crops.

PRACTICAL EXAMPLES

Precision farming techniques can be used to monitor and manage different crops for optimised cultivation practices. For example, in vineyards, creating vigour maps illustrating the speed of shoot growth can help represent vegetative variability and determine the intensity of nitrogen supply or defoliation required for the desired result. Equipment such as variable rate fertilisers, leaf strippers or precision harvesters can be used to precisely dose inputs based on these maps.

Similarly, monitoring the temperature of individual plants can be a reliable indicator of water stress in maize cultivation. It is also possible to assess the condition of fruit tree stems or wood, monitor soil moisture levels, and check the correct internal temperature of plants using precision farming techniques. These examples demonstrate the versatility of precision farming in different crops and conditions. 

AGRICULTURE USE OF DRONE WITH SPECIAL ACCESSORIES

Corn

Biological treatment against corn borers using drones, through a tank, distribute useful insect eggs Trichogramma brassicae (Hymenoptera parasitoid of the corn borer larvae).

It avoids the use of tractors and then reducing to zero the damage to crops and environmental impact, and significantly increasing the speed and accuracy of application.
