Organic matter serves as a reservoir of nutrients and water in the soil, improves soil structure, and promotes a healthy ecosystem of soil microbes. High levels indicate a healthy, productive soil.

Soil pH affects nutrient availability, microbial activity, and plant growth. A pH range of 6 to 7.5 is generally suitable for most crops, as it allows for optimal nutrient uptake.

Microbial biomass refers to the total mass of microorganisms in the soil. It is a key indicator of soil health, as a diverse and active microbial community supports nutrient cycling and suppresses disease.

Soil erosion rates indicate the loss of topsoil due to water or wind. Low erosion rates are essential for maintaining soil thickness and preventing loss of nutrients and organic matter.

Water holding capacity is the soil's ability to retain moisture for use by plants. High water holding capacity can reduce the need for irrigation and increase drought resistance.

The rate at which nitrogen is converted from organic to inorganic forms, making it available to plants. Healthy soils exhibit a stable nitrogen mineralization rate, ensuring a steady supply of nitrogen.

CEC is the soil's ability to hold and exchange cations (positively charged ions). Soils with high CEC can store more nutrients and have greater fertility.

Soil texture, determined by the percentage of sand, silt, and clay, affects water retention, drainage, aeration, and the ability of plant roots to penetrate the soil.

Soil structure refers to the arrangement of solid parts of the soil and of pore space located between them. Good structure is important for root growth, water infiltration, and aeration.

Bulk density is the mass of soil in a given volume. Low bulk density indicates good soil porosity, which is favorable for root growth and microbial activity.

Soil salinity is the salt content in the soil. Excessive salinity can limit plant growth and decrease crop yield by impairing water uptake and causing toxicity.
