Influence of agro activities on the amount of nutrients in cotton irrigation

It was also observed in the movement of nitrogenous and phosphorous nutrients in the general form, and it was 0.069 and 0.162%, respectively, in the 0-30 cm soil driving layer at the beginning of the application period, and at the end of the application period, it increased by 0.003 and 0.002% in the double-planted variants, and by 0.001% in single rows. it was stated that a decrease was observed. In the options where seeds are planted under a transparent tape, it is worth noting another important aspect of the tape. As mentioned above, the movement of nutrients is accelerated due to the increase in moisture in the fields under the tape, while the watering intervals are longer due to the longer preservation of moisture in the 0-30 and 0-70 cm layers of the soil. and it was found that the irrigation rates are reduced by 1.5-2.0 times compared to the control option, and by 1.0-1.5 times compared to the options with a black tape between cotton rows.
