Real-Time Testing of Soil Qualities using Raspberry PI

Soil fertility plays a vital role in the soil's capacity to support plant growth. It is assessed through various factors, including macro and micro nutrients, water content, and pH levels. Each harvest depletes soil nutrients, necessitating their replenishment, often through the use of fertilizers. Farmers typically estimate the required fertilizer amounts, but applying too much or too little can negatively impact plant health and lower yields. Although soil testing is a common practice for monitoring nutrient levels, it can be time-consuming and yield inconsistent results between laboratory tests and field conditions. To address these issues, a new soil testing tool with temperature, color, and pH sensors provides real-time information on soil parameters like temperature, pH, and color. This tool offers a more precise and effective substitute for conventional soil testing techniques.
