Agrobiology is an interdisciplinary field of study that provides a comprehensive understanding of the complex relationships between crops, soils, and the environment. Agrobiology consists of several science-based disciplines including, plant biology and nutrition, agronomy , ecology , genetics , molecular biology , and soil science .
Phosphorus is a primary factor of soil fertility as it is an element of plant nutrients in the soil. It is essential for cell division and plant development, especially in seedlings and young plants. [10] However, phosphorus is becoming increasingly harder to find and its reserves are starting to be depleted due to the excessive use as a ...
Nitrogen is an essential element needed for the creation of biomass and is usually seen as a limiting nutrient in agricultural systems. Though abundant in the atmosphere, the atmospheric form of nitrogen cannot be utilized by plants and must be transformed into a form that can be taken up directly by the plants; this problem is solved by biological nitrogen fixers.
Energy – ability a physical system has to do work on other physical systems. Farm equipment – any kind of machinery used on a farm to help with farming. Food engineering – multidisciplinary field of applied physical sciences which combines science, microbiology, and engineering education for food and related industries.
A four-ox-team plough, circa 1330. The ploughman is using a mouldboard plough to cut through the heavy soils. A team could plough about one acre (0.4 ha) per day. The typical planting scheme in a three-field system was that barley, oats, or legumes would be planted in one field in spring, wheat or rye in the second field in the fall and the third field would be left fallow.
An agronomist, field-sampling a trial plot of flax. This topic of agronomy involves selective breeding of plants to produce the best crops for various conditions. Plant breeding has increased crop yields and has improved the nutritional value of numerous crops, including corn, soybeans, and wheat. It has also resulted in the development of new ...
A field of sunflowers in Cardejón, Spain (2012) A field of rapeseeds in Kärkölä, Finland (2010) In agriculture, a field is an area of land, enclosed or otherwise, used for agricultural purposes such as cultivating crops or as a paddock or other enclosure for livestock. A field may also be an area left to lie fallow or as arable land. [1]
The three fields were rotated in this manner so that every three years, one of the fields would rest and lie fallow. Under the two-field system, only half the land was planted in any year. Under the new three-field rotation system, two thirds of the land was planted, potentially yielding a larger harvest.
