Nutrients 16 elements: • C, H, O, • Macronutrients • Micronutrients August 2008
Macronutrients • Nutrients required in large quantities • N • P • K • Ca • Mg • S August 2008
Primary Nutrients • N • P • K • Primary because they are needed in large amounts August 2008
Secondary Macronutrients • Ca • Mg • S Only moderate amounts required August 2008
Micronutrients (Nutrients needed in small quantities) • • • B Cu Cl Fe Mn August 2008 • Mo • Na • Zn
How to Remember? ? • C HOPKNS Ca Fe Mg (C. Hopkins café might good) Remaining nutrients: B, Cu, Cl, Mn, Mo, Zn August 2008

Fertilizer August 2008
What is fertilizer? Any material added to the soil to provide nutrients that will increase growth, yield, or nutritional value of the plants. August 2008
Fert. Classifications • Inorganic • Natural Organic • Synthetic Organic August 2008
Inorganic Fert. • Non-living sources (minerals/rocks) • Chemically made August 2008
Inorganic Fert. Characteristics: • Nutrients in soluble form and quickly made available to plants • Should not come in contact with roots or foliage for long time period August 2008
Natural Organic • From plant/animal material Characteristics: • N usually predominant • Nutrients are only made available to the plants as the materials decay in soil, so SLOW ACTING & LONG LASTING August 2008
Natural Organic Examples: • Animal manure • Cottonseed meal • Soybean meal • Dried blood • Dried ground/sewage sludge • Bone meal August 2008
Synthetic Organic Fert. • Made from carbon based materials August 2008
