Potassium is an elementary macronutrient besides Nitrogen and Phosphorus for growth of plants. It performs crucial metabolic activities like photosynthesis, activation of enzyme and protein synthesis. Rhizospheric microorganisms are the keysegments of viable agricultural ecosystems.These perform a vital characterbyresolving the unobtainable Potassium form and make accessible forroots of plants. Potassium concentrations which are soluble in the soil are generally less though above 90% Potassium present in the soil subsist in the form of insoluble rock. Solubilization of a certain configuration of K is done by effective K-solubilizers treatment to an obtainable structure of K in the soil. The obtained form of K should be simply absorbed by the plant. Some selected bacterial and fungal isolates based on their morphological characteristics were assessed for their potentiality to resolve K from insolvable K trace. The selected isolates were in the form of rods, Gram positive and motile. This review assays on the morphological study of K-solubilizers for their remarkable supremacy in forming zone of solubilization.
The enhancing requirement for organic products seeks at resolving difficulties of organic production systems. Primary hindrance for this production system is weed management. The base of weed control in organic farming is cultivation. Organic farmers implement eco-friendly management practices against less efficiency products, uncertain weather conditions, cost, potential hazard to soil health. System level practices that include crop rotation and cover cropping mostly recognized as weed management weapons. Somehow weed control should be implemented with proper knowledge of weed biology and these operations may get less profit or even enlarged weed population. Organic farmers embrace new management systems to enhance the outcome of pre-existing practices. Invention of modern cultivation tools leads to improved efficiency, faster and better working rate shows good result in control of weeds. Eco-friendly management practiced with the support of these tools centralize on reducing weed, increasing crop-weed interference will produce reliable weed management systems for organic farming.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
