It has never been more important than now to understand how to optimise the growth of crops plants in agriculture. As a result of continued increases in the human population on planet earth, and changes in consumer behaviour, agricultural production needs to increase by 60% over the next 40 years to meet the rising food demand. Total arable land is projected to increase only by less than 5% by 2050, so additional production will need to come from increased productivity. Whether you are a good earth citizen or have a job or business that supports agriculture, this book, Rain & Shine aims to refresh your understanding of the fairly simple story of what makes plants grow, and its place in modern agriculture.
