A soil profile consists of two layers. Layer A is \(30\) cm deep with a field capacity of \(0.30\) m³ m⁻³ and a wilting point of \(0.15\) m³ m⁻³. Layer B is \(70\) cm deep with a field capacity of \(0.35\) m³ m⁻³ and a wilting point of \(0.20\) m³ m⁻³. The soil is initially at field capacity. A crop requires \(12\) mm of water per day for \(15\) consecutive days. Assuming no rainfall, determine the number of days irrigation must be applied after the soil moisture falls to the wilting point, if irrigation supplies water at the same daily rate as the crop requirement.
