INTERNATIONAL CERTIFIED CROP ADVISER- NUTRIENT MANAGEMENT TERMS ACTUAL 2025/2026 QUESTIONS AND 100% CORRECT ANSWERS Acid Soil - Answer -A soil that has a pH value less than 7.0 Aerobic - Answer -A condition identified by the presence of oxygen Agronomic nutrient rate - Answer -Amount of supplemental nutrient required by a crop for a realistic yield goal (yield potential), after all the soil, water, plant, and air credits are considered. Agronomic rates consider nutrient credits from all soil tests, legumes, manure residuals, and any other nutrient source Alkaline soil - Answer -A soil that has a pH value greater than 7.0 Alum - Answer -A potassium aluminum sulfate or ammonium aluminum sulfate Ammonium (NH4+) - Answer -A form of nitrogen that is available to plants and is derived from fertilizer addition and soil organic matter mineralizationAmmonium nitrate solution - Answer -Non-pressure solution of ammonium nitrate in water usually standardized to 20% nitrogen used for direct application or for making multinutrient liquid fertilizer. Analysis is 20-0-0 Ammonium phosphates - Answer -A group of phosphorus fertilizers manufactured by the reaction of anhydrous ammonia with superphosphoric acid to produce either solid or liquid fertilizers Ammonium sulfate - Answer -Fertilizer material with an analysis of 21- 0-0. Also contains 24% sulfur Anaerobic - Answer -A condition identified by the absence of oxygen Anhydrous ammonia (NH3) - Answer -Fertilizer in pressurized gas form, made by reacting nitrogen in air with hydrogen gas (H2) under high temperature and pressure in the presence of a catalyst. The analysis is 82-0-0 Animal unit - Answer -1,000 pounds of live animal weight; a term used to determine volumes of animal manure produced Anion - Answer -An ion with a negative charge. Common soil anions are chloride, nitrate, sulfate and bicarbonate Anion exchange capacity - Answer -The sum total of exchangeable anions that a soil can adsorb at a specific pH. Expressed as centimoles of charge per kilogram (cmolc/kg) of soil or milliequivalents per 100 g of soil (meq/100 g of soil) Application rate - Answer -The weight or volume of a fertilizer, soil amendment, or pesticide applied per unit areaAqua ammonia - Answer -A 20% N solution made by dissolving anhydrous ammonia in water. Available nutrient - Answer -A nutrient in a form that a plant can absorb. Banded nutrients - Answer -Placing solid granular or liquid fertilizer in a band on the soil surface or ejected below the soil surface before, at, or after planting Base saturation percentage - Answer -The proportion of the soil's cation exchange capacity occupied by basic cations (sodium, potassium, magnesium and calcium). Bioremediation - Answer -The use of biological agents to remove substances hazardous to human health or the environment from contaminated soil or water Biosolid - Answer -Any organic material, such as livestock manure, compost, sewage sludge, or yard wastes applied to the soil to add nutrients or for soil improvement Buildup and maintenance - Answer -Nutrients applied in order to build up a target soil test level and then maintained by annual addition of the qua
