The article reports on the Kemira GrowHow T-Sum map that has been developed to predict the optimum timing for early nitrogen applications. South west Great Britain is the first area in the region to reach T-Sum 200. It has been proven that T-Sum 200 is the optimum time to apply fertilizer to gain the maximum benefit.
