SEGH Representation - Scientific Events in Pakistan

10 January 2016
Dr Munir Zia gives an update on SEGH representation at two scientific events during 2015 in Pakistan

 

Dr Munir Zia represented SEGH at two of the following events during 2015 in Pakistan:

1. International Conference on Soil Sustainability and Food Security held at the University of Agriculture in Faisalabad (Nov 15-17)

2. International Workshop on Current status of fertilizer use in Pakistan (Nov 29-Dec 01)

Dr Munir Zia, R&D Coordinator for the Fauji Fertilizer Company in Pakistan, while representing SEGH, delivered an invited talk on “Health risk assessment of potentially harmful elements (PHEs) and dietary minerals (DMs) from soils and vegetables irrigated with wastewater” at the International Conference on Soil Sustainability and Food Security held at the University of Agriculture in Faisalabad, Pakistan. Scientists from Germany, Australia, and UAE also participated in the event that was inaugurated by the Federal Minister for Food Security.

 

Dr Munir Zia also represented SEGH at an International Workshop on  the Current status of Fertilizer use in Pakistan. The workshop in November 2015 was organised by the University of Agriculture in Faisalabad and the International Centre for Agricultural Research in Dry Areas (ICARDA) under the framework of the Consortium Research Programme on Water, Land and Ecosystems.

 

 

The main concern in agricultural production systems are the inefficient use of fertilizers and their impact on the environment. Improving fertilizer use efficiency requires a multi-disciplinary, multi-pronged approach in fertilizer and irrigation management, breeding, extension and policy interventions. The contrasting situation is the underuse of fertilisers where farmers are not achieving optimal yields because they cannot get access to or afford fertilizers. This workshop will highlight the problem of fertilizer mismanagement; its over, inappropriate and under use, and losses due to agricultural activities. This activity will help in the identification of areas for policy intervention to improve fertilizer distribution and management or regulate its use.

  • The influence of application of biochar and metal-tolerant bacteria in polluted soil on morpho-physiological and anatomical parameters of spring barley 2020-01-27

    Abstract

    The paper presents the results of the model experiment on spring barley (Hordeum vulgare L.) grown in polluted soil. The influence of separate and combined application of wood biochar and heavy metal-tolerant bacteria on morpho-physiological, anatomical and ultrastructural parameters of H. vulgare L. has been studied. The joint application of biochar and bacteria increased the shoot length by 2.1-fold, root length by 1.7-fold, leaf length by 2.3-fold and dry weight by threefold compared to polluted variant, bringing the plant parameters to the control level. The maximal quantum yield of photosystem II decreased by 8.3% in H. vulgare L. grown in contaminated soil, whereas this decrease was less in biochar (7%), bacteria (6%) and in combined application of bacteria and biochar (5%). As for the transpiration rate, the H. vulgare L. grown in polluted soil has shown a decrease in transpiration rate by 26%. At the same time, the simultaneous application of biochar and bacteria has led to a significant improvement in the transpiration rate (14%). The H. vulgare L. also showed anatomical (integrity of epidermal, vascular bundles, parenchymal and chlorenchymal cells) and ultrastructural (chloroplasts, thylakoid system, plastoglobules, starch grains, mitochondria, peroxisomes, ribosomes, endoplasmic reticulum, vacuoles) changes, revealed by light-optical and transmission electron microscopy of leaf sections. The effects were most prominent in H. vulgare L., grown in polluted soil but gradually improved with application of biochar, bacteria and their combination. The use of biochar in combination with metal-tolerant bacteria is an efficient tool for remediation of soils, contaminated with heavy metals. The positive changes caused by the treatment can be consistently traced at all levels of plant organization.

  • Earthworms and vermicompost: an eco-friendly approach for repaying nature’s debt 2020-01-23

    Abstract

    The steady increase in the world’s population has intensified the need for crop productivity, but the majority of the agricultural practices are associated with adverse effects on the environment. Such undesired environmental outcomes may be mitigated by utilizing biological agents as part of farming practice. The present review article summarizes the analyses of the current status of global agriculture and soil scenarios; a description of the role of earthworms and their products as better biofertilizer; and suggestions for the rejuvenation of such technology despite significant lapses and gaps in research and extension programs. By maintaining a close collaboration with farmers, we have recognized a shift in their attitude and renewed optimism toward nature-based green technology. Based on these relations, it is inferred that the application of earthworm-mediated vermitechnology increases sustainable development by strengthening the underlying economic, social and ecological framework.
