Any laboratory test (soil or tissue test) performed by a commercial company will cost the grower a fee. Laboratory tests take at least a week to complete, usually 2 weeks. It takes time to dry the samples, send them to the lab, complete the lab-tests, and then return the results to the grower.
Aquatic diversity is an important component of agricultural biodiversity. The conservation and sustainable use of local aquatic ecosystems, ponds, rivers, and coastal commons by artisanal fisherfolk and smallholder farmers is important to the survival of both humans and the environment.
Agrobiology is defined by Merriam-Webster as a field that studies how plant or crop nutrition, growth, and yield or production relate to soil management (Merriam-Webster). ). Agrobiology is an interdisciplinary field of study that provides a comprehensive understanding of the complex relationships between crops, soils, and the environ
Agronomy is the science and technology of producing and using plants by agriculture for food, fuel, fiber, chemicals, recreation, or land conservation.Agronomy has come to include research of plant genetics, plant physiology, meteorology, and soil science.

Farmers have manipulated plants and animals through selective breeding for decades of thousands of years in order to create desired traits. In the 20th century, a surge in technology resulted in an increase in agricultural biotechnology through the selection of traits like the increased yield, pest resistance, drought resistance, and herbicide resistance.
