Soil is a natural resource that plays an important role in ecosystems and agriculture because it is a source of nutrients and a medium for the absorption of nutrients by plants. The purpose of this study was to analyze the soil properties and soil fertility in marigold flower plots. Varee Chiang Mai School focuses on the study of physical properties such as structure, color, adhesion, temperature, and moisture of soil, as well as chemical properties such as pH and macronutrient content (nitrogen, phosphorus, and potassium).
The study was conducted by collecting soil samples from marigold plots and conducting analysis according to the GLOBE Program standards. (N, P, K) Soil pH Meter and Soil Temperature and Moisture Meter. The results showed that the soil in the study area had a pH value in the range of 6.5-6.9, which is suitable for plant to grow. However, it has been found that the nitrogen and phosphorus content in the soil is low, which may be a limited factor for plant growth.
Based on the results of this research, it is recommended that add soil organic matter such as compost and manure to increase nitrogen and phosphorus content, as well as improve soil and water management to maintain optimal soil moisture. This study can be used as a guide to improve soil quality and promote more efficient cultivation of marigolds.
