Abstract
Abstract
Background and purpose: The use of mineral soil conditioners such as natural zeolite compounds to improve the physical and chemical properties of the soil and to prevent the wastage of chemical fertilizers and also to eliminate the destructive effects caused by the use of chemical fertilizers in agricultural fields is one of the modern solutions. Although the use of chemical fertilizers to compensate for the lack of nutrients and increase plant yield is known as a quick solution, but the use of these fertilizers in many cases leads to environmental pollution, ecological damage and ultimately increases production costs, so fertilizers Biological as natural inputs can be used as a supplement or substitute for chemical fertilizers
that It has recently received attention. The present study was conducted with the aim of the effects of zeolite and biofertilizers on the absorption of nutrients in two varieties of corn (6010 and ns71) in Neka city.
Materials and methods: This research was carried out during the agricultural years of 1396-1397 and 1397-1398 in Mazandaran province, Neka city, in the form of one-time chopped plots in the form of a randomized complete block design with three replications. Corn cultivars in two levels of corn 6010 and ns71 as the main factor and the use of zeolite and biological fertilizers in six levels of zeolite consumption, bacteria consumption, mushroom consumption, zeolite + bacteria consumption, zeolite + mushroom consumption and zeolite + bacteria + mushroom consumption as secondary factors. are considered
Results: The results showed that The highest nitrogen and zinc content in soil was obtained by combined application of zeolite and biofertilizers, while the maximum phosphorus and iron content in the soil was obtained by separate application of zeolite. The highest reduction of soil phosphorus in both crop years related to the treatment of zeolite+bacteria+fungus and the separate use of bacteria was obtained with an average of 9.04 and 9.13 ppm, respectively. Also, the maximum reduction of soil iron was achieved with the simultaneous application of zeolite+bacteria+fungus with about 25% reduction compared to zeolite treatment in the first year in ns71 variety. The maximum soil potassium content was obtained with an average of 383.8 ppm in the conditions of individual application of bacteria for cultivar 6010 during both cropping years, and the lowest soil potassium content with a decrease of about 47.3 and 45.8 percent respectively for The cultivars 6010 and ns71 were obtained under conditions of combined use of zeolite+bacteria+fungus. The minimum content of zinc in the soil was observed in the conditions of separate use of bacteria and fungi in both years of the study. The minimum soil magnesium content with decrease of about 20.2% was obtained for ns71 variety in the first year of the experiment.
Conclusion: The obtained results showed that the simultaneous application of zeolite+bacteria+fungus caused the maximum reduction of pH in the soil.
