A genus of Gram-negative, aerobic, rodshaped bacteria of the family Rhizobiaceae, typically plant pathogens that form galls or tumors on roots or stems.
agrobacterium (s), agrobacteria (pl)
Short rod-shaped aerobic bacteria of the genus Agrobacterium, that cause plant diseases; such as, crown gall.
agrobiologist (s) (noun)
, agrobiologists (pl)
An expert or specialist in the study of plant nutrition and growth in relation to the conditions of soils.
agrobiology (s) (noun) (usually no plural)
1. The study of the breeding, nutrition, and growth of crops; especially, in relation to soil management.
2. The quantitative science of plant life and plant nutrition.
The businesses collectively associated with the production, processing, and distribution of agricultural products.
1. A chemical; such as, a hormone, fungicide, or insecticide, that improves the production of crops.
2. A chemical used in agriculture; especially, a biologically active one such as a weedkiller or a fungicide.
3. A chemical used to improve the quality of farm products.
4. Of or relating to the use of chemicals in agriculture.
Any of a class of opines present in crown gall, a type of plant tumor.
An opine is a bacterial growth substance coded for by genes injected into the plant genome from Agrobacterium, a parasitic bacterium that causes crown gall disease in the plants it infects.
agroclimatology (s) (noun)
, agroclimatologies (pl)
The study of climates as applied to the effect on the productivity of plants and animals of agricultural importance.
agroecologist (s) (noun)
, agroecologists (pl)
An expert in or a student of the design, development, and management of sustainable agricultural systems: "An agroecologist studies the applications of ecological principles while considering existing social, cultural, and economic factors of farming communities."
agroecology (s) (noun)
, agroecologies (pl)
1. The study of the relationship between the environment and agricultural crops.
2. The study of the relationships between agricultural systems and their environments.
3. Ecology as applied to agriculture.
agroeconomic, agro-economic; agroeconomics, agro-economics
1. Pertaining to a nation's agricultural economy.
2. The financial problems of farmers as a group, etc.
1. The ecological relationships of agriculture in general or of a particular agricultural locale.
2. The biotic and abiotic components of an agricultural system, including not only the livestock and cultivated crops; but also, for example, the water supply; other plant and animal species, soil characteristics, climate, and human input.
The ecological relationships of agriculture in general or of a particular agricultural locale.
agroforestry (s) (noun)
, agroforestries (pl)
A form of land use in which woody perennials thrive on the same piece of land and are integrated along with conventional harvest-producing plants and livestock: Modern applications of agroforestry is the intentional growing of trees on the identical unit of ground as agricultural crops and with pastures for farm animals that are raised to produce commodities; such as, meat, milk, leather, and wool.
agrogeological, agrogeologic, agrogeologically
A reference to the study of rock minerals of importance to farming and horticulture, especially with regards to soil fertility and fertilizer components.
Additional details regarding agrogeological fertilization
By adding rock dust as a complete plant fertilizer along with plant matter, the soil may be much healthier.
- Rock dusts contain most of the nutrients essential for growth except for nitrogen and phosphorous.
- The release of nutrients is directly related to weathering; therefor, their beneficial effect could last for many years before needing replacement, and even longer if used in conjunction with sustainable farming techniques.
- The problem of nutrient leaching is minimized as plants take up the nutrients at the same rate as they are being released and there is also minimal problem with toxicity from oversupply of nutrients.
- Some dusts raise pH, countering the effects of soil acidity often found in certain soils.
If the soil is healthier then the plants will be healthier. Mixed rock dust can provide a full spectrum of minerals to the soil and this improves cellular structure, which could explain why rock dusted plants are more resistant to insect attacks and diseases.
It has been noted that the use of rock dust can reduce (or even replace) fertilizers, pesticides, fungicides and herbicides.
