Biomass Digestion to Produce Organic Fertilizers: A Case-Study on Digested Livesto...

The study examined the perception of benefits of organic gardening in Maiduguri Metropolis, Nigeria. Structured questionnaires were administered to obtain information from 166 respondents through multi-stage random and purposive sampling techniques. Data collected were analysed using descriptive statistics (frequency distribution, percentage and mean scores). The study indicates that the respon...

The present study was carried out to investigate biochemical responses of marigold (Calendula officinalis L.) to Bio-organic fertilizers. Effects of co-inoculation of two plant growth-promoting rhizobacteria (PGPR) (Azotobacter sp.145PI and Azospirillum sp.AC49I), humic acid (HA) (10 kg ha−1), vermicompost (VC) (7 T ha−1) and combinations of these treatments were evaluated in two marigold culti...

Field experiments were conducted to study the effect of organic matrix based slow release fertilizers (SRFs) on plant growth, nitrate assimilation and seed yield of Brassica juncea L. cv, pusa bold. The agro-waste materials like cow dung, clay soil, neem leaves and rice bran were mixed together in 2:2:1:1 ratio and used as organic matrix for the immobilization of chemical fertilizer nutrients w...

in order to study individual and integrated effects of biological, organic and chemical fertilizers on milk thistle (silybum marianum l.) quantitative and qualitative traits, a field experiment was conducted at research station, faculty of agriculture, ferdowsi university of mashhad, iran during growing season of 2010-2011. a complete randomized block design with twelve treatments and three rep...

In the current research, the effects of some organic fertilizers as fulvic and humic acids on the vegetative growth of pistachio seedlings in a semi-hydroponic culture containing Fe-EDDHA (as a synthetic fertilizer) and FeSO4 (as an inorganic fertilizer) were investigated. The alkalinity is recognized as a main problem in pistachio orchards, therefore the pH of nutrient solution was ...

We tested the efficacy of matrix-based fertilizers (MBFs) to improve Kentucky bluegrass (Poa pratensis L.) growth while reducing NH, NO3, dissolved reactive phosphorus (DRP), and total phosphorus (TP) compared to commercial slowrelease fertilizer (SRF) Polyon®, ESN®, and Avail® in greenhouse column studies. The MBFs covered a range of inorganic N and P in compounds that are relatively loosely b...
