Why monitor the physical parameters of crops?

Is it worth using satellite data on my farm? What is the purpose of monitoring physical parameters?
Physical parameter monitoring is one of the applications of satellite data. Here is a list of possible applications of the knowledge of each parameter in agricultural practice.

Chlorophyll:

• The direct relationship of the amount of chlorophyll with the available nitrogen in the soil and in the plant.
• A basic input layer for creating variable rate application maps for fertilizer application during production and quality fertilization.
• Monitoring the impact of applied agronomic measures - especially fertilization, but also POR application.
• Planning of the harvesting campaign (chlorophyll loss during ripening).
• Detection of anomalies on the plot - weed areas.

LAI:

• Corresponds to the amount of biomass.
• Monitoring biomass increments.
• Basic input layer for creating variable application maps for fertilizer application during production and quality fertilization.
• Monitoring the impact of applied agronomic measures - especially fertilisation.

Water in vegetation foliage:

• A very dynamic parameter that reflects the amount of available water in the soil and the plant's ability to use the water.
• Planning of the harvesting campaign (as the vegetation matures, the water in the foliage is naturally lost).
• Planning the application of POR to allow the plant to bridge the temporary dry period.
• Detection of anomalies on the plot - areas of weeds later in the crop phenophase, waterlogged areas.
