A biofertilizer is a substance which contains living micro-organisms which, when applied to seeds, plant surfaces, or soil, colonize the rhizosphere or the interior of the plant and promotes growth by increasing the supply or availability of primary nutrients to the host plant. [1]
Community-level composting in a rural area in Germany. Compost is a mixture of ingredients used as plant fertilizer and to improve soil's physical, chemical, and biological properties.
Fertilizers of an organic origin (the first definition) include animal wastes, plant wastes from agriculture, seaweed, compost, and treated sewage sludge . Beyond manures, animal sources can include products from the slaughter of animals – bloodmeal , bone meal , feather meal , hides, hoofs, and horns all are typical components. [ 24 ]
A nutrient cycle (or ecological recycling) is the movement and exchange of inorganic and organic matter back into the production of matter. Energy flow is a unidirectional and noncyclic pathway, whereas the movement of mineral nutrients is cyclic.
plant geography (or phytogeography in strict sense, chorology, floristics); plant sociology (or phytosociology , synecology – however, this field does not prescind from flora study, as its approach to study vegetation relies upon a fundamental unit, the plant association , which is defined upon flora).
A bioeffector is a viable microorganism or active natural compound which directly or indirectly affects plant performance (biofertilizer), and thus has the potential to reduce fertilizer and pesticide use in crop production.
Biogeography is the study of the distribution of species and ecosystems in geographic space and through geological time.Organisms and biological communities often vary in a regular fashion along geographic gradients of latitude, elevation, isolation and habitat area. [1]
In modern mapping, a topographic map or topographic sheet is a type of map characterized by large-scale detail and quantitative representation of relief features, usually using contour lines (connecting points of equal elevation), but historically using a variety of methods.
