  • Toxic and allelopathic ipomoea yields plant-friendly Organic Fertilizer
    Journal of Cleaner Production, 2017
    Co-Authors: Naseer Hussain, Tasneem Abbasi, Shahid Abbas Abbasi
    Abstract:

    Abstract The composition and the Fertilizer value of vermicompost derived solely from ipomoea, a weed known for its toxicity and allelopathy, has been studied employing Fourier transform Infrared Spectroscopy (FT-IR) and plant bioassay (germination and seedling growth). The impact of ipomoea’s vermicompost on the physicochemical and biological characteristics of the soil was also studied. FT-IR analysis revealed that chemical compounds that are responsible for the deleterious effect of ipomoea are largely destroyed in the course of ipomoea’s vermicomposting. The ipomoea vermicompost was seen to be a good Organic Fertilizer as it significantly enhanced germination success, promoted growth of the seedlings and induced plant friendly physicochemical and biological features to the soil. The studies raise the possibility that very large quantities of biomass that are generated by ipomoea across the world can be utilized in producing Organic Fertilizer through vermicomposting. This may also provide a means of checking the seemingly unstoppable spread of ipomoea and cushioning its adverse impacts.

  • vermicomposting eliminates the toxicity of lantana lantana camara and turns it into a plant friendly Organic Fertilizer
    Journal of Hazardous Materials, 2015
    Co-Authors: Nasee Hussai, Tasneem Abbasi, S A Abbasi, Tasneem Abbasi, Shahid Abbas Abbasi
    Abstract:

    Abstract In evidently the first study of its kind, vermicompost derived solely from a weed known to possess plant and animal toxicity was used to assess its impact on the germination and early growth of several plant species. No pre-composting or supplementation of animal manure was done to generate the vermicompost in order to ensure that the impact is clearly attributable to the weed. Whereas the weed used in this study, Lantana (Lantana camara), is known to possess strong negative allelopathy, besides plant/animal toxicity in other forms, its vermicompost was seen to be a good Organic Fertilizer as it increased germination success and encouraged growth of all the three botanical species explored by the authors – green gram (Vigna radiata), ladies finger (Abelmoschus esculentus) and cucumber (Cucumis sativus). In terms of several physical, chemical and biochemical attributes that were studied, the vermicompost appeared plant-friendly, giving best results in general when employed at concentrations of 1.5% in soil (w/w). Fourier transform infrared spectrometry revealed that the phenols and the sesquiterpene lactones that are responsible for the allelopathic impact of Lantana were largely destroyed in the course of vermicomposting. There is also an indication that lignin content of Lantana was reduced during its vermicomposting. The findings open up the possibility that the billions of tons of phytomass that is generated annually by Lantana and other invasives can be gainfully utilized in generating Organic Fertilizer via vermicomposting.

  • mechanisms by which Organic Fertilizer and effective microbes mitigate peanut continuous cropping yield constraints in a red soil of south china
    Applied Soil Ecology, 2018
    Co-Authors: Wei Chen, Ying Teng, Zhengao Li, Peter Christie
    Abstract:

    Abstract Red soils are acid soils which occupy about one fifth of the total area of tropical and subtropical soils in China. Peanut (Arachis hypogaea L.) is regarded as the main oil and cash crop in the red soil region. However, yields of peanut have gradually but significantly declined under continuous cropping. We conducted a field experiment in Jiangxi province, south China from 1996 to investigate the mitigation of the peanut continuous cropping constraint. Three types of Fertilizer (chemical, Organic, and Organic Fertilizer with effective microbes) were applied in the field. After 20 years of cropping the continuous cropping constraint was found to be more severe where chemical Fertilizers were applied and was mitigated where the fields were amended with Organic Fertilizer or Organic Fertilizer with effective microbes. Soil properties and the rhizosphere bacterial community structure were determined in 2016. Long-term application (20 years) of Organic Fertilizer increased the plant available phosphorus in the rhizosphere soil. Phosphorus is known to be one of the most limiting factors for peanut growth in red soils and peanut yield was promoted as the soil phosphorus status increased. Organic Fertilizer and effective microbes also optimized the rhizobacteria of peanut to mitigate the continuous cropping obstacle. The bacterial wilt pathogen (Ralstonia) decreased in abundance in the rhizosphere and bacterial wilt disease of peanut declined significantly. Moreover, beneficial bacteria in the rhizosphere capable of promoting peanut growth increased in abundance.
