Humus is rich in organic matter and nutrients, which are essential for plant growth. A higher proportion of humus ensures that the soil has a higher nutrient content. Clay soils hold water well but can become compacted, making it difficult for roots to penetrate. A lower amount of clay ensures that the soil is not too heavy, allowing for proper root development. A lower proportion of sand ensures adequate water retention in the soil for plant growth. Therefore, a higher proportion of humus, lower amounts of clay and sand would be the best choice for availability of nutrients, water, and root development.
