The article presents the results of an analysis of greenhouse soil for nitrogen and phosphorus content when using vermifertilizers and the Baikal biological product. Experimental samples of greenhouse soil were taken from a greenhouse where cucumbers were grown. The work was out as part of comprehensive study to the effectiveness of vermicomposts and biological products when growing cucumbers in the conditions of Central Yakutia. According to the conditions of the experiment, 10 variants were formed: in variant 1, a greenhouse soil mixture without vermicomposts and biological products; in variant 2 to 5 – greenhouse soil mixture with 50, 100, 150 and 200 g/plant of vermicompost from cattle manure; variant 6 and 7 – greenhouse soil mixture with 100 and 200 g/plant of vermicompost from bird droppings; variant eight – greenhouse soil mixture with 100 g/plant of humus and 100 ml of Baikal EM-1; variant nine – greenhouse soil mixture with 100 ml Baikal EM-1; variant ten - greenhouse soil mixture with liquid vermicompost (vermichay). It was found that the use of vermifertilizers helps to optimize the nitrogen and phosphorus content in greenhouse soil. Thus, the research present the perspective of using vermifertilizers when growing vegetables in Yakutia.
