Farmers can add lime to raise the pH and make it less acidic, which enhances nutrient availability and promotes better plant growth.

Soil texture determines how well soil retains water; for example, clayey soils retain more water than sandy soils.)

Soil testing helps farmers identify nutrient deficiencies and tailor their fertilizer applications, promoting efficient nutrient use and better crop yields.

Soil microorganisms decompose organic matter, releasing nutrients for plants to absorb, thus promoting nutrient cycling and plant growth.

Shallow soils may limit root development, affecting crop selection, and deep soils allow for deeper root penetration, influencing crop choices and their ability to access water and nutrients.
