Grafting is referred to as the artificial method of propagation in which parts of plants are joined together in order to make them bind together and continue growing as one plant. Grafting is mainly applied to two parts of the plant: the dicot and the gymnosperms due to the presence of vascular cambium between the plant tissues: xylem and phloem.
Plants are often grown in a soilless medium in order to supply the proper amounts of water and nutrients to the root zone as well as supplemental lighting to ensure a sufficient daily light integral. CEA plant growing optimizes the use of resources such as water, energy, space, capital and labor.
When selecting plants for the landscape, observations of the location must be made first. Soil type, temperature, climate, light, moisture, and pre-existing plants are considered when selecting plant material for the location. Plant selection may be for annual displays, or they may be for more permanent plantings.
Agronomy – science and technology of producing and using plants for food, fuel, feed, fiber, and reclamation.. Organic gardening – science and art of growing fruits, vegetables, flowers, or ornamental plants by following the essential principles of organic agriculture in soil building and conservation, pest management, and heirloom variety preservation.
For example, root-knot nematode is a serious problem for some plants in warm climates and sandy soils, where it slowly builds up to high levels in the soil, and can severely damage plant productivity by cutting off circulation from the plant roots. Growing a crop that is not a host for root-knot nematode for one season greatly reduces the level ...
Strip cropping helps to stop soil erosion by creating natural dams for water and preserving the strength of the soil. Certain layers of plants will absorb minerals and water from the soil more effectively than others. When water reaches the weaker soil that lacks the minerals needed to make it stronger, it normally washes it away.
In a general context, both can refer to agriculture. Within agriculture, both can refer to any kind of soil agitation. Additionally, "cultivation" or "cultivating" may refer to an even narrower sense of shallow, selective secondary tillage of row crop fields that kills weeds while sparing the crop plants.
Plant domestication is seen as the birth of agriculture. However, it is arguably proceeded by a very long history of gardening wild plants. While the 12,000 year-old date is the commonly accepted timeline describing plant domestication, there is now evidence from the Ohalo II hunter-gatherer site showing earlier signs of disturbing the soil and cultivation of pre-domesticated crop species.
