Since water and nitrate enter deeper soil strata over time and are initially depleted in surface soil strata, root systems with rapid exploitation of deep soil would optimize water and N capture in most maize production environments. The overall premise is that soil resource acquisition is optimized by the coincidence of root foraging and resource availability in time and space. It will depend on the steepness of the hill and your car.A hypothetical ideotype is presented to optimize water and N acquisition by maize root systems. Is it clear? If it is, use as much or as little accelerator as you need to move at a safe speed.Indicate right (if you’re pulling out from the kerb), check your mirrors and look over your shoulder.Gently release the handbrake or parking brake.It’s still a hill start however, and there are some specific steps to follow: Hill starts are easier when facing downhill than uphill, as gravity is working with you. Just move your foot straight from the footbrake to the accelerator. If you’re driving one of these cars you don’t have to worry about using the handbrake. Some modern automatic cars have a button or foot-operated parking brake instead of a handbrake.This leaves your left hand free to control the handbrake as you take off. If your indicator is on the left side of the steering wheel, indicate before you use the handbrake.On many automatics the car will hold position while you move your foot from the brake to the accelerator.Is it clear? If it is, smoothly push down on the accelerator and pull away.When you’ve got that steady control, indicate, check your mirrors and look over your shoulder.If you start to roll back, pull up the handbrake again and use the foot pedals to find the right level of control. Push down on the accelerator a little.Hold the handbrake up so it is still engaged.Pull the handbrake up a bit and press the release button.Facing downhill this means turning the steering wheel to the left, or facing uphill to the right.
Angle your front wheels towards the kerb.On really steep hills you may need to use a lower gear (‘L’, ‘1’ or ‘2’ on older automatic gear shifts).You’ll need to brake sooner and harder than you would on the flat when you want to come to a stop.You’ll need to use more accelerator to keep at a constant speed than you would when driving on the flat.
