Organic nitrogen (ON) is the most common form of nitrogen in the soil. If this form is the most abundant then many new questions must be addressed in order to fully understand the breakdown of ON such as what organisms are incorporating the nitrogen, the rate of uptake and the effect of concentration on uptake rate. Many measurements have been made regarding the uptake rate of amino acid in soi...

The production of maize has significant nutrient needs, notably for nitrogen. Considering the negative impact chemical fertilizer on ecosystem, alternative supply nutrients that is easily accessible and environmentally benign must be sourced. This study looked into effects inoculating mycorrhizae diazotrophs growth biomass output maize. treatments included three (3) levels mycorrhiza (without m...

In recent years, escalating chemical fertilizer costs have imperiled the economic feasibility of coffee cultivation in Peru, resulting reduced yields across plantations. This study aimed to assess biofertilizers' effect on growth and biomass three varieties. Employing a complete factorial design (A×B), Factor A encompassed varieties: Castillo, Catuaí, Obata, while B comprised five treatments: e...

In addition to their well-recognized roles in plant nutrition and communities, mycorrhizas can influence the key ecosystem process of soil aggregation. Here we review the contribution of mycorrhizas, mostly focused on arbuscular mycorrhizal fungi (AMF), to soil structure at various hierarchical levels: plant community; individual root; and the soil mycelium. There are a suite of mechanisms by w...

Orchids are cultivated by tissue culture because their seeds do not have food reserves (endosperm) for growth. All nutrient requirements obtained from media. Propagation causes them to no association with Rhizoctonia mycorrhizae, which needed in growth so that they can interfere orchid both vegetatively and generatively. mycorrhizae a group of sp. form mutual symbiotic orchids. Each has differe...

water deficiency is one of the most important factors for limiting crop yield in arid and semiarid regions. symbiosis with a variety of microorganisms in these regions is one of the modern ecological approaches for sustainable agriculture to reduce damages caused by environmental stresses. symbiotic of arbuscular mycorrhizal fungi (am) with the roots of crops has shown positive effects on agric...

Norby et al center their critique on the design of the data set and the response variable used. We address these criticisms and reinforce the conclusion that plants that associate with ectomycorrhizal fungi exhibit larger biomass and growth responses to elevated CO2 compared with plants that associate with arbuscular mycorrhizae.

Wijayakusuma ornamental plant (Epiphyllum oxypetalum (DC.) Haw.) is a that easily propagated by cuttings. To overcome this problem, it necessary to pay attention the planting media used. This study aims determine effectiveness of providing based on biotechnology agents growth plants. quasi-experimental quantitative using Randomized Block Design, used six treatments with four replications. Follo...
