The world of agriculture is changing quickly with all the new technology. Artificial intelligence (AI); automated planting, spraying, and harvesting; and nutrient management are all being incorporated into farming operations to increase efficiency and yields. This article will focus on changes in nutrient management. Plant nutrition impacts yield and the quality of our food supply and impacts pests (weeds, insects, disease). Most farmers have insufficient data for the immediate nutrient needs of a plant, leading to fertilizer misapplication and significant challenges in fruit and grain quality. Good plant nutrition at the right time improves plant health, soil health and also reduces issues with pests. Extensive research has established the link between disease susceptibility and specific nutritional imbalances associated with each disease. By managing a crop’s nutritional needs, it is possible to significantly reduce or even eliminate pest susceptibility, however, farmers need to meas...
