Paperback. Etat : new. Paperback. 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.The first part, What Makes Plants Grow, reminds us of our critical dependence on green plants. This based on the supply of energy from the sun through the process of green plant photosynthesis, to build up a range of carbohydrates and then a myriad of organic chemicals, to support life across the earth. The oxygen derived from photosynthesis makes other life possible, and in making arrangements between living things in ecosystems. The second part, How We Grow Plants, traces the growing awareness of humans of the secret life of plants and the more recent scientific understanding of the processes, especially in producing food for the people of the planet. Shipping may be from multiple locations in the US or from the UK, depending on stock availability.…
