Two hectares of cotton field in an arid zone at flowering and boll formation stages was irrigated in 10h with a stream of 150L/s. Irrigation was started when 50% of available moisture is depleted. Following results were obtained in the field determination of moisture in the soil after irrigation. The bulk density of the soil is 1.4g/cm3.

Calculate the quantity of water reached to the field.

Calculate the amount of water present in the soil in cubic meters after irrigation.

If the soil were reached to the field capacity after irrigation, what would be the average moisture percentage in the root zone before irrigation?
