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]
Compost tea is made up of extracts of fermented water leached from composted materials. [ 67 ] [ 73 ] Composts can be either aerated or non-aerated depending on its fermentation process. [ 74 ] Compost teas are generally produced from adding compost to water in a ratio of 1:4–1:10, occasionally stirring to release microbes .
Grain meals can be made of corn gluten, alfalfa, cottonseed, or soybean. Most supply nitrogen and potassium, but soybean meal provides nitrogen and phosphorus. [ 27 ] When initially spread they can cause an increase in ammonia within the soil and burn seeds, it is recommended to use these after plants have developed, to ensure crop success.
Biofertilizer: Most discussions about the economic value of crop residues focus on the equivalent fertilizer cost of the nutrients within. Although crop residues contain both macronutrients and micronutrients , only macronutrients such as nitrogen , phosphorus , potassium and sulfur are economically significant.
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.
Like synthetic surfactants, they are composed of a hydrophilic moiety made up of amino acids, peptides, (poly)saccharides, or sugar alcohols and a hydrophobic moiety consisting of fatty acids. Correspondingly, the significant classes of biosurfactants include glycolipids , lipopeptides and lipoproteins, and polymeric surfactants as well as ...
Seaweed fertiliser is organic fertilizer made from seaweed that is used in agriculture to increase soil fertility and plant growth. The use of seaweed fertilizer dates back to antiquity and has a broad array of benefits for the soils.
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.
