According to statistical analysis (ANOVA) comparison, two of the semi-organic mixtures performed considerably better than the two commercial samples evaluated. Potential benefits profoundly associated with these nutrient mixtures as compared to similar liquid fertilizer products on the market is that most nutrients are chelated and dissolved in solution. Also, the mixtures contain all necessary nutrients including plant growth substances required for healthier plant growth. The most important socioeconomic impact is the value addition to the technology chain in the citrus industry. The use of fluid fertilizers in significant quantities is less than twenty years old. Nevertheless, growth has been so rapid that in South Africa demand for mixed liquid fertilizer has greatly increased from 90 000 tons NPK & blended micronutrients in 1955 to more than 600 000 per annum tons today (Report 41/2003, Department of Minerals and Energy). The liquid fertilizers market is sparsely specialized with major competitors like Omnia, Kynoch and Foskor supplying more than 50 % of the market demand. Amongst the nutrient mixtures formulated, mixture one is an NPK (1-1-2) based nutrient mixture containing both secondary nutrients (0.5 % Mg & 1.0 % Ca) and seven micronutrients (0.1 % Fe, 0.05 % Cu, 0.05 % Zn, 0.05 % Mn, 0.02 % B, 0.0005 % Mo and 0.0005 % Co). The composition of this mixture offers the formula a potential to be used as a general purpose (all stages of plant growth) fertilization mixture in view of its balanced composition (containing all essential plant nutrients). Mixture two contains essentially the micronutrients and in higher concentrations (0.3 % Fe, 0.3 % Cu, 0.1 % Zn, 0.2 % Mn, 0.02 % B, 0.0005 % Mo and 0.0005 % Co) as compared to mixture one except for boron, molybdenum and cobalt. The concentration of the micronutrients contained in this mixture is adequately high which offers a potential for it to be used in supplementing nutrition in plants with critical micronutrient-deficient symptoms. Mixture three is very similar to mixture two (1.0 % Fe, 0.05 % Cu, 0.05 % Zn, 0.05 Mn, 0.05 % B, 0.0005 % Mo and 0.0005 % Co) except that the concentrations of all seven micronutrients are considerably less than those of contained in mixture two. However, the concentration of iron in this mixture is as high as 1.0 %. The mixture has a potential to be used in high iron-deficient situations. Mixture four is an organic formula with relatively low nutrient concentrations (NPK-0.02-0.02-1, 0.27 % Mg, 0.02 % Ca, 0.008 % Fe, 0.26 % Cu, 0.012 % Zn, 0.009 % Mn). Nevertheless, this mixture is appealing for organically grown crops where the use of chemicals is prohibited by standards. These lemon juice-based nutrient mixtures were further characterized and tested for stability and storability over a period of eight weeks. This study revealed no major change in the physical quality (colour, pH and “salt out” effect). The basic formulation methodology is a two-step procedure that involves filtration of the lemon juice to remove membranous materials, mixing at ambient temperature and stabilization of the nutrient mixtures. However, for the organic nutrient formula mix, filtration follows after extraction of nutrients from plant materials using the lemon juice.]]> Thu 13 May 2021 01:15:13 SAST ]]> A baseline for information security knowledge for end users https://vital.seals.ac.za/vital/access/manager/Repository/vital:9808 Thu 13 May 2021 01:13:23 SAST ]]> A case study of child-centred play therapy with a child suffering from posttraumatic stress disorder https://vital.seals.ac.za/vital/access/manager/Repository/vital:26431 Thu 13 May 2021 01:09:29 SAST ]]> A case study approach to assess the growth towards world class at EH Walton Packaging (Pty) Ltd https://vital.seals.ac.za/vital/access/manager/Repository/vital:9816 Thu 13 May 2021 01:07:02 SAST ]]> A comparison of the labour dispute resolution systems of South Africa and Swaziland https://vital.seals.ac.za/vital/access/manager/Repository/vital:10204 Thu 13 May 2021 00:57:40 SAST ]]> A case study of industrial relations climate in Zimbabwean mining company https://vital.seals.ac.za/vital/access/manager/Repository/vital:9435 Thu 13 May 2021 00:32:50 SAST ]]> "To learn how to speak": a study of Jeremy Cronin's poetry https://vital.seals.ac.za/vital/access/manager/Repository/vital:8484 Thu 13 May 2021 00:20:55 SAST ]]> A comparative study of performance and efficiency of a tube and fin type domestic solar water heat collector https://vital.seals.ac.za/vital/access/manager/Repository/vital:24329 Thu 13 May 2021 00:01:18 SAST ]]> 'n Ondersoek na die uitbeelding van Khoisan-karakters deur wit Afrikaanse prosateurs: 1994-2014 https://vital.seals.ac.za/vital/access/manager/Repository/vital:29819 Fri 20 Aug 2021 18:16:26 SAST ]]> A comparative assessment of dairy calf feeding management systems at Fernwood Dairy Farm, Alexandria, Eastern Cape https://vital.seals.ac.za/vital/access/manager/Repository/vital:40468 Fri 15 Mar 2024 12:24:52 SAST ]]>
