Which class of soil is categorized as marginal for pasture?

Class 6 soils are categorized as marginal for pasture due to several inherent characteristics that limit their suitability for agricultural use, particularly in grazing conditions. These soils typically have considerable restrictions that may include limitations in their ability to retain moisture, nutrient deficiencies, and poor drainage. Because of these limitations, Class 6 soils often cannot support optimal grass growth, which is essential for sustaining livestock.

In terms of pasture development, Class 6 soils are often characterized by shallow depth, stoniness, or acidity that significantly reduces productivity. As a result, while it is possible to establish some form of pasture, the yields would be lower, and maintaining healthy livestock could be challenging.

This contrasts with the other classes, where Class 4 soils can support limited pasture activities but are generally more conducive to agriculture than Class 6. Class 5 soils have more suitable conditions for pasture than Class 6 and are often utilized for low-intensity grazing. Class 7 soils are mostly unsuitable for pasture and agricultural development, posing more severe limitations for any crop or pasture growth. Hence, Class 6 is rightfully identified as marginal for pasture use.
