The food security issue was addressed by the development of "modern agriculture" in the last century. But food safety issues and environment degradation were the consequences suffered as a result. Climate change has been recognized as the result of release of stored energy in fossil fuel into the atmosphere. Homogeneous crop varieties, machinery, pesticides and fertilizers are the foundation of...

In order to investigate the effect of different levels of nitrogen and bio-fertilizers on yield of canola plants in Qazvin, Iran, a split-plot design was conducted on the base of randomized complete block design with four replications. Treatments included 3 levels of nitrogen (0, 75 and 150 kg ha-1) and bio-fertilizers on four levels (no inoculation, Azotobacter, Azospirillum and a combination ...

This paper shows a simple procedure for the quantification of industrial and laboratory samples of Ammonium Sulphate-Nitrate fertilizers (ASN) based on a Rietveld fit from X-ray powder diffraction profiles. The Rietveld fit is performed by means of the structural models of the double salts 2NH4NO3·(NH4)2SO4 and 3NH4NO3·(NH4)2SO4, previously reported by the authors. The proposed method demonstra...

Investigations of the plant food requirements for sugarcane grown on the wind-blown, sandy soils of marine origin typical of the Natal coast, have. occupied the' attention, of numerous investigat6rsin past 'years. In some cases there has been shown to be little response to phosphate, whilst in the case of inorganic salts of potash and nitrogen a lack. of response or even a depressing effect on ...

The term “Precision Forestry” is being used more frequently in the forest products industry. This paper defines two broad categories of precision forestry as 1) using geospatial information in forest management and planning, and 2) site-specific silvicultural operations. One case study is presented for site-specific application of herbicides and fertilizers in herbaceous weed control activities...

Crop production by the use of sustainable methods in agriculture has become the order of the day as there is a growing concern to conserve the environment and make the earth last longer for posterity. Keeping this end in view there is a constant search for manures and fertilizers that are eco-friendly and biodegradable. Vermicomposting is a novel method of decomposing organic matter and produci...

Decisions can be taken to increase energy efficiency and to mitigate the emissions to the environment by examining the energy audit and greenhouse gas (GHG) emissions footprint of crop production in different ways and in different regions, with comparable principles. In this study, energy consumption and energy indices of tomatoes production in four regions of Iran including East Azerbaijan...

The number of studies investigating the effect of bio-fertilizers is increasing because of their importance in sustainable agriculture and environmental quality. In our experiments, we measured the effect of different fertilizers on soil respiration. In the present study, we were looking for the cause of unexpected changes in CO2 values while examining Chernozem soil samples. We concluded that ...

ventional monocultural crop systems often supported by high inputs of pesticides and fertilizers to sustainable agriculture. Although precise definitions of sustainable agriculture vary, one key aspect is a reduction in agrichemical inputs with a corresponding shift to alternative crop protection strategies, such as cultural practices, organic amendments, resistant or tolerant crop varieties, a...
