8 Managing Soil pH and Crop Nutrients

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.

reduces photosynthetic rates and nutrient uptake by the crop. Since low light intensity sometimes occurs when soils are waterlogged or temperatures are cool, cloud cover can exacerbate the capacity of the crop to take nutrients. Diseases and pests can have an important impact on crop-nutrient uptake by competing for nutrients, affecting

Photosynthetic organisms can produce glucose from the prod-ucts of photosynthesis, where the energy in sunlight is used to reduce carbon dioxide (CO2). These organisms will either use the glucose to make ATP or store it in other energy-rich molecules like starch. When photosynthetic organisms are eaten or decom-

God spends a day making light (before making the stars) and separating light from darkness; then, at the end of a hard day's work, and almost as an afterthought, he makes the trillions of stars. 1:16 "And God set them in the firmament of the heaven to give light upon the earth."

These organisms produce ecosystem food that supports the food chain, hence they are referred to as primary producers. The balanced equation for photosynthesis that is correct, but seldom used, is 6CO 2 + 12H 2 O = C 6 H 12 O 6 + 6H 2 O + 6O 2. Water
