Täsmäviljely

Täsmäviljely, also known as precision agriculture, is a farming management concept based on observing, measuring, and responding to inter- and intra-field variability in crops. The goal is to optimize returns on inputs while preserving or enhancing resource sustainability. Täsmäviljely involves using technology to gather data about fields, such as soil conditions, crop health, and weather patterns. This data is then analyzed to make more informed decisions about where, when, and how much to plant, fertilize, irrigate, and apply pesticides.

Key technologies associated with täsmäviljely include GPS and GIS (Geographic Information Systems) for precise location tracking and mapping, sensors (e.g., soil moisture sensors, optical sensors) for real-time data collection, drones and satellite imagery for aerial monitoring, and variable rate technology (VRT) for applying inputs only where and in the amounts needed. VRT, for example, allows for precise application of fertilizers or seeds based on the specific needs of different zones within a field.

By adopting täsmäviljely practices, farmers can achieve a number of benefits. These include increased crop yields, reduced use of fertilizers, pesticides, and water, leading to lower costs and environmental impact. It also contributes to improved farm efficiency and profitability. The concept has gained traction globally as a way to enhance agricultural productivity and sustainability in the face of growing food demand and environmental challenges.
