Item Precision agriculture : an introduction(University of Missouri--Columbia. Extension Division, 2026) Davis, Glenn; Casady, William; Massey, Ray"Precision agriculture gives farmers the ability tomore effectively use crop inputs including fertilizers,pesticides, tillage and irrigation water. More effectiveuse of inputs means greater crop yield and(or)quality, without polluting the environment. However,it has proven difficult to determine the cost benefitsof precision agriculture management. At present,many of the technologies used are in their infancy,and pricing of equipment and services is hard to pindown. This can make our current economicstatements about a particular technology dated." -- SummaryItem Community watershed management organizational structure styles(University of Missouri--Columbia. Extension Division, 2026) Downing, Dan; Broz, Bob"This guide gives three approaches and a set of guidelines to be used as a checklist for determining which approach may be best suited for any given situation. Please note, however, these are only guidelines. Furthermore, at this time the establishment of watershed management groups is a voluntary effort not required by federal or state regulation." -- first pageItem Precision agriculture : an introduction(University of Missouri--Columbia. Extension Division, 2026) Davis, Glenn; Casady, William; Massey, Ray"Precision agriculture merges the new technologies borne of the information age with a mature agricultural industry. It is an integrated crop management system that attempts to match the kind and amount of inputs with the actual crop needs for small areas within a farm field. This goal is not new, but new technologies now available allow the concept of precision agriculture to be realized in a practical production setting." -- first pageItem Nitrate in drinking water(University of Missouri--Columbia. Extension Division, 2026) Downing, Daniel"Nitrate (NO ) is the primary source of nitrogen (N) for plants; it is a nutrient they cannot live without. Nitrates are naturally occurring in soil and water. Extensive farming can rob the soil of its natural nitrogen source, so farmers often add nitrate fertilizers. Properly managed, nitrogen does not endanger health and can increase crop production. However, when more nitrogen is added to the soil than the plants can use, excess nitrate can leach into groundwater supplies and contaminate wells. On-site sewage systems (such as septic tanks and lagoons) also can be a source of nitrate pollution. Because nitrate is converted to a very toxic substance (nitrite) in the digestive systems of human infants and some livestock, nitrate-contaminated water is a serious problem." -- first pageItem Operating considerations for biosolids equipment(University of Missouri--Columbia. Extension Division, 2023) Hu, Zhiqiang"The land area required for biosolids depends upon the amount and characteristics of biosolids produced, and the crops, soils characteristics and agronomic practices used. The amount of land that must be covered influences decisions on types and sizes of equipment needed to manage biosolids. The following table is an estimate of land area requirements for various size municipalities." -- first page
