Charlie Carp is great for increasing yields on winter and summer crops. We recommend spraying all over the foliage until point of drip off - this allows the the plant to take in the macro and micro nutrients immediately through their foliage, whilst the drip off nourishes the soil. We recommend spraying twice during the growing season. Firstly spray when you have a good coverage of foliage over the paddock and secondly as a top dress.
