Obtaing Organomineral Fertilizers on Base of Local Raw Materials and Nitrogen-fixing Microorganisms

Abstract

The article presents results of research on the production of organomineral fertilizers based on local raw materials cattle manure (CM), Kyzylkum phosphorite flour (FF) and Navbahor bentonite (NB) and nitrogen-fixing microorganisms (NFM). CM: NB: NFM=100.0: 2.5: (0-4) and CM: NB: FF: NFM= 100.0: 5.0: 2.5: (0-4) in obtaining new types of organomineral fertilizers ratios are used. Composting time is taken from 1 day to 60 days. The physico-chemical and commercial properties of the obtained new type of organomineral fertilizers were studied. The contents of organomineral fertilizer samples were analyzed by modern physico-chemical methods.
 Composting local ores (FU and NB) with cattle manure and processing the resulting mixture with a solution containing nitrogen-fixing microorganisms led to an increase in humic substances, a plant-available form of phosphorus and, most importantly, an increase in nutrient components. Determined that the amount of nitrogen in the organomineral fertilizer obtained due to the biofixation of atmospheric molecular nitrogen is 3.2-4.1 times higher than in the case where NFM was not applied.

Studying the process of phenological monitoring of late varieties of plums grown in the climatic conditions of Namangan region

“…One of the objectives of our research is related to the study and analysis of plum varieties grown in the Yangikurgan district of the Namangan region, which has extensive experience in growing plum fruits in our Republic [6][7][8][9][10][11].…”

The influence of organo-mineral fertilizers on the growth of evening apple varieties throughout the year

“…One of the tasks of the research carried out by us is to compare late apple varieties Starkrimson (five stars), Renet Simirenko, Golden delicacies and Boyken varieties grown on the farm "Nazirjon Ilkhomjon Arabboy" in Iskovot village, Yangikurgan district, Namangan region [3] A number of organomineral fertilizers are related to the study and analysis of the effect of organic mineral fertilizers [4][5][6][7][8][9][10] obtained on the basis of local raw materials and nitrogen-fixing microorganisms on apple varieties through phenological and biometric observations.…”

Production of organomineral fertilizers based on local raw materials and nitrogen-fixing microorganisms

“…in these experiments. they were prepared on the basis of dung and phosphorite in the proportions of mass dung: phosphorite (from 100: 5 to 100: 30) was selected in the ratio [17].…”
