International Certified Crop Adviser (Nutrient Management System) Exam with Correct answers

International Certified Crop Adviser (Nutrient Management System) Exam with Correct answers Acid Soil - CORRECT ANSWER-A soil that has a pH value less than 7.0 Aerobic - CORRECT ANSWER-A condition identified by the presence of oxygen Agronomic nutrient rate - CORRECT 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 - CORRECT ANSWER-A soil that has a pH value greater than 7.0 Alum - CORRECT ANSWER-A potassium aluminum sulfate or ammonium aluminum sulfate Ammonium (NH4+) - CORRECT ANSWER-A form of nitrogen that is available to plants and is derived from fertilizer addition and soil organic matter mineralization Ammonium nitrate solution - CORRECT 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 - CORRECT 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 - CORRECT ANSWER-Fertilizer material with an analysis of 21-0-0. Also contains 24% sulfur Anaerobic - CORRECT ANSWER-A condition identified by the absence of oxygen Anhydrous ammonia (NH3) - CORRECT 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 - CORRECT ANSWER-1,000 pounds of live animal weight; a term used to determine volumes of animal manure produced Anion - CORRECT ANSWER-An ion with a negative charge. Common soil anions are chloride, nitrate, sulfate and bicarbonate Anion exchange capacity - CORRECT 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 - CORRECT ANSWER-The weight or volume of a fertilizer, soil amendment, or pesticide applied per unit area Aqua ammonia - CORRECT ANSWER-A 20% N solution made by dissolving anhydrous ammonia in water. Available nutrient - CORRECT ANSWER-A nutrient in a form that a plant can absorb. Banded nutrients - CORRECT 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 - CORRECT ANSWER-The proportion of the soil's cation exchange capacity occupied by basic cations (sodium, potassium, magnesium and calcium). Bioremediation - CORRECT ANSWER-The use of biological agents to remove substances hazardous to human health or the environment from contaminated soil or water Biosolid - CORRECT 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 - CORRECT ANSWER-Nutrients applied in order to build up a target soil test level and then maintained by annual addition of the quantity of nutrients expected to be removed in the harvested portion of the cro
