Good agricultural practice (GAP) are specific methods which, when applied to agriculture, create food for consumers or further processing that is safe and wholesome. While there are numerous competing definitions of what methods constitute good agricultural practice there are several broadly accepted schemes that producers can adhere to.
Food and Agricultural Organization of the United Nations GAP
The Food and Agricultural Organization of the United Nations (FAO) uses good agricultural practice as a collection of principles to apply for on-farm production and post-production processes, resulting in safe and healthy food and non-food agricultural products, while taking into account economical, social and environmental sustainability.
GAPs may be applied to a wide range of farming systems and at different scales. They are applied through sustainable agricultural methods,
Economically and efficiently produce sufficient (food security), safe (food safety) and nutritious food (food quality);Research that works for developing countries and Australia. Retrieved 25 November 2007. GAPs require maintaining a common database on integrated production techniques for each of the major agro-ecological area (see ecoregion), thus to collect, analyze and disseminate information of good practices in relevant geographical contexts.

The United States Department of Agriculture Agricultural Marketing Service currently operates an audit/certification program to verify that farms use good agricultural practice and/or good handling practice. This is a voluntary program typically utilized by growers and packers to satisfy contractual requirements with retail and food service buyers. The program was implemented in 2002 after the New Jersey Department of Agriculture petitioned USDA-AMS to implement an audit based program to verify conformance to the 1998 Food & Drug Administration publication entitled, "Guide to Minimize Microbial Food Safety Hazards for Fresh Fruits and Vegetables."
The program has been updated several times since 2002, and includes additional certification programs such as commodity specific audit programs for mushrooms, tomatoes, leafy greens, and cantaloupes. In 2009, USDA-AMS participated in the GAPs Harmonization Initiative which "harmonized" 14 of the major North American GAP audit standards, which in 2011 resulted in the release and implementation of the Produce GAPs Harmonized Food Safety Standard.
Demand for agricultural crops is expected to double as the world's population reaches 9.1 billion by 2050. Increasing the quantity and quality of food in response to growing demand will require increased agricultural productivity. Good agricultural practices, often in combination with effective input use, are one of the best ways to increase smallholder productivity. Many agribusinesss are building sustainable supply chains to increase production and improve quality.
Reducing erosion by wind and water through hedging and ditchingApplication of fertilizers at appropriate moments and in adequate doses (i.e., when the plant needs the fertilizer), to avoid run-off (see nitrogen balance method).Maintaining or restoring soil organic content, by manure application, use of grazing, crop rotationReduce soil compaction issues (by avoiding using heavy mechanical devices)Maintain soil structure, by limiting heavy tillage practices FAO : GAP : FAO GAP Principles : SoilIn situ green manuring by growing pulse crops like cowpea, horse gram, sunn hemp etc.Practice scheduled irrigation, with monitoring of plant needs, and soil water reserve status to avoid water loss by drainagePrevent soil salinization by limiting water input to needs, and recycling water whenever possibleAvoid crops with high water requirements in a low availability regionAvoid drainage and fertilizer run-offMaintain permanent soil covering, in particular in winter to avoid nitrogen run-offManage carefully water table, by limiting heavy output of waterRestore or maintain wetlands (see marshlands)Provide good water points for livestock (FAO : GAP : FAO GAP Principles : Water)Harvest water in situ by digging catch pits, crescent bunds across slopeAnimal production, health and welfare
