Definition - What does Agronomy mean?
Agronomy is a practice and science of plant production that comes from technology and agricultural applications, both traditional and holistic. Most crops are monitored by an agronomist (a plant scientist) who notes all aspects from soil conditions to crop needs (like nutritional requirements and pest control). Agronomists are hired by farmers and viticulturists to advise them on how to keep their crops and soil healthy and produce the best yields; agronomists often work with botanists, edaphologists and pedologists as well.
WineFrog explains Agronomy
The science of agronomy is what develops new practices that can be implemented onto certain crops and in agricultural farms. These scientists determine how the crops are growing, what is influencing their growth patterns and how to make effective changes to promote natural growth. In vineyards, this can include acknowledging the presence of certain diseases or funguses, noting the soil content and conditions, what nutrients the grapevines require and which environmental factors are influencing the overall yield. They can also help farmers determine which grape species will grow best on what types of soil and geological/geographical conditions, which is instrumental to planting the correct type of grapevine and planning a vineyard.
Agronomists also think on a larger scale, like sustainability and long-term profitability. With these concepts in mind, they can address issues like water conservation, soil technologies to improve the life of the soil and crop analysis to aid in long term viability.
