{{id}} {{{paragraph}}}
Managing Soil pH and Crop Nutrients 91 The inherent complexity of crop production systems requires integrating many factors to ensure maxi-mum crop yields with the least risk to the environment. Assessing present- and reserved- nutrient status of the soil, understanding its nutrient -release and nutrient -holding capacity, and knowing the plant and environmental factors that impact nutrient availability are necessary to guide fertilization rates, sources, and method of application of additional Nutrients . The information here is intended to provide fundamental principles to help the reader under-stand what to do, and why, when making management decisions related to phosphorus (P), potassium (K), sec-ondary macronutrients (calcium [Ca], magnesium [Mg], and sulfur [S]), micronutrients (boron [B], chlorine [Cl], copper [Cu], iron [Fe], manganese [Mn], molybdenum [Mo], and zinc [Zn]), and pH.
Assessing present- and reserved-nutrient status of the soil, understanding its nutrient-release and nutrient-holding capacity, and knowing the plant and environmental factors that impact nutrient availability are necessary to guide fertilization rates, sources, and method of application of additional nutrients.
