Soil Sample 16. -123.8473° S, 207.3765° E. September 19, 2024.
This soil chromatography shows a well-defined structure with a concentric distribution of green, brown, and darker tones towards the outer areas, providing detailed information about the biological and chemical state of the soil.
The central area, with an intense green radial pattern, indicates a very healthy biological activity, with a strong presence of active microorganisms. This green coloration suggests a good amount of organic matter in the decomposition process, with microorganisms efficiently contributing to nutrient mineralization and transformation.
The immediately outer bands, in lighter green, indicate good nutrient availability and proper integration with organic matter. These bands show that the soil can retain and process essential nutrients needed for plant growth.
The peripheral zone, dark brown with some lighter areas and irregular patterns, may suggest the presence of certain chemical blockages or compaction in some parts of the soil. These areas could indicate minor issues with water circulation or gas exchange, but they do not seem to significantly affect the overall balance of the soil.
Overall, this chromatography reflects a soil with very active biological activity, well-structured, with a good capacity to retain nutrients and support plant growth. The small indicators of potential blockages in the outer zones could be easily managed to maintain a healthy and productive soil.
Soil Sample 18. 190.4758° S, -219.8654° E. September 19, 2024.
This soil chromatography shows a detailed structure with well-defined concentric bands, providing a clear reading of the soil’s condition.
The central area, characterized by a radial green and brown pattern, indicates healthy biological activity with a strong presence of active microorganisms. The intense green color suggests an active decomposition of organic matter, with microorganisms transforming nutrients into plant-accessible compounds.
The immediately outer bands, with a mix of green and brown tones, show good integration of organic matter and minerals. This color combination is a positive sign of a balanced soil, where the mineralization of organic matter provides the necessary nutrients for plant growth. Smooth transitions between zones indicate good water circulation and uniform nutrient access.
The peripheral zone presents an interesting pattern with rounded greenish shapes that appear as small accumulations. These shapes could indicate certain concentrations of nutrients or organic matter that are stabilizing. Although these accumulations might suggest some degree of nutrient circulation blockage, they do not seem to significantly affect the overall soil balance.
Overall, this chromatography indicates a healthy soil with good biological activity and a well-formed structure for water and nutrient retention. The small accumulations observed in the peripheral zone could be indicators of local concentrations, but in general, the soil demonstrates a balanced capacity to maintain adequate fertility and support plant growth.
Soil Sample 22. -182.7654° S, 188.9237° W. September 19, 2024.
The analysis of soil chromatography No. 22 reveals a concentric structure with different patterns and colors that indicate soil quality. In the center, a light-colored area with a radial distribution of fine lines is observed, suggesting a good presence of colloidal compounds and a balanced structure for water and nutrient retention. This center is surrounded by a transition toward brown and green tones, indicating microbiological activity and organic matter in different stages of decomposition.
The transition zones display well-defined waves and ring-shaped patterns, highlighting a well-structured soil with healthy biological activity. The presence of well-marked ridges suggests a uniform distribution of microorganisms and nutrients, while the valleys form clear boundaries that could indicate a slight imbalance in some minerals. In certain areas, variations in line continuity are observed, which may reflect irregularities in the distribution of soil components.
The outer band of the chromatography is characterized by the presence of fine reddish-brown lines, which could indicate a high presence of iron and other oxidized minerals. This external zone shows good stability, as the patterns are relatively uniform, suggesting that the soil has a proper structure and the capacity to retain nutrients without signs of excessive compaction.
The colors present in this chromatography provide key information: the white in the center indicates good colloidal capacity, the green tones show high biological activity and a good amount of organic matter, while the brown and reddish hues point to the presence of minerals in balance. The combination of these colors and patterns suggests that the analyzed soil has a stable structure and a good level of fertility, although some areas may require improvement in mineral balance.
Finally, compared to other chromatographies of fertile soils, this one generally shows good quality, with active biological activity and a well-balanced nutrient profile. To further optimize this soil, compost application could be reinforced to improve the homogeneous distribution of microorganisms and ensure an optimal mineral balance.
