Influence of Previous Crops on the Amount of Nutrients In the Soil

Abstract

Soils of the Republic of Karakalpakstan are salty and low in fertility. In such soils, the meliorative condition of soils should be improved and soil fertility should be increased for receiving high yield from agricultural crops. Crop rotation, organic and siderate fertilizers give good results in increasing soil fertility.

In the field experiment, studies were conducted to determine the effect of crops included in short crop rotation systems on the amount of soil nutrients. In determining the effect of mung bean, sesame, and soybeans planted before winter wheat in the crop rotation system on the amount of nutrients in the soil, when planted by the method of cotton: previous crop mung bean + mung bean for siderate + 20 t/ha of manure + winter wheat: winter wheat the amount of humus in the soil has been found to have increased to 0.040%.
