This volume of the Albrecht Papers presents the logical connections among soil health, animal health and human health. There is a need for a restored respect among both farmers and scientists for the importance of soil health. From this respect, a commitment to restoring the natural fertility and productivity of the soil must arise as a means of restoring health to humanity.

"Nature works and has been working for a billion and a half years-ever since there were living things on earth. This is important. We talk of controlling nature, but any wise farmer or stockman knows that nature makes the rules for us to learn and follow, if we can. In short, the ecologist is in a position to furnish us, in many ways, models which we can follow in our own operations. Before the prairies were settled, plowed and fenced, wild herds moved back and forth across them, never staying in one place after the grass was cropped too short. These moving herds distributed minerals from their droppings and remains, for it is well-known that wild animals usually maintain a good mineral balance by visiting salt-licks and varying their pasture-grounds. Here in a nutshell is the model for proper use of grasslands. It takes a lot of common sense to get across the information we need. He has it and can put it out so we can all understand it."--Wheelers.co.nz.

The contributions in this book describe the role soils play for plant, animal and human health. They show that soil- and human health are intricately connected, because healthy soils produce healthy crops, which in turn nourish humans and animals, allowing for their health and productivity. Soil quality directly influences the quality and quantity of food that can be produced, as soils provide essential macro- and micronutrients and attenuate environmental pollutants. On the other hand, these same pollutants, thus concentrated in soils, may cause soils to become toxic and degraded. Soils (and their crops) may also be responsible for exposure to pests and pathogens, while, at the same time, providing drug substances and may even suppress diseases. Soil quality is vital on a global scale, as more than 800 million people around the world are undernourished, implying that their intake of food is insufficient to meet their daily energy needs, and the deficiency of essential micronutrients is even more widespread. Nearly one third of the world's population is affected by zinc deficiency, while iron deficiency affects nearly 3 billion people. Climate change has been shown to affect animal and human health, and soils are intricately linked to the atmosphere by being both a source and sink of greenhouse gases. Soils are the largest active terrestrial reservoir of organic carbon and its sequestration in soils can be enhanced by improved management practices. The book summarizes the current state of research of these important issues and provides a comprehensive treatise of the global importance of soils to for humankind.

The International Code of Conduct for the Sustainable Use and Management of Fertilizers or Fertilizer Code was developed to increase food safety and the safe use of fertilizers. The Fertilizer Code aims to address issues of global importance, thereby contributing to the implementation of some of the Sustainable Development Goals (SGDs). It essentially provides a locally adaptable framework and a voluntary set of practices to serve the different stakeholders directly or indirectly involved with fertilizers. It is expected that these stakeholders will contribute to sustainable agriculture and food security from a nutrient management perspective, by adhering and help implementing the voluntary guidelines and recommendations provided. The Fertilizer Code is the result of a broad and intensive consultation process initiated in December 2017, unfolded until February 2019, as recommended by the Committee on Agriculture and finally endorsed by the 41st FAO Conference in June 2019.
