The world of compost and how it relates to healthy soil is a fascinating, complex story. Compost helps to create and maintain healthy soil – the foundation of growing organically. It is also cost-saving, easy and fun, and a fantastic way to learn and connect with nature. Most importantly, composting is really beneficial for the environment as it massively reduces the amount of noxious methane gas generated from burying food waste in landfill. In How to Make and Use Compost, composting expert Nicky Scott reveals why making compost is so important for healthy soil and the environment, how it works and how to make your own compost. He provides clear guidance on the most appropriate system for your site, whether you're composting in a garden or a kitchen, and explains how different composting systems work, including cold composting, wormeries, bokashi and hot boxes. This practical book features an A-Z guide to what you can and cannot compost, composting techniques, common problems and their solutions – from Activators to fertilise the soil with microbial food sources, to Z for Zoo poo if you're lucky enough to live near a wildlife sanctuary! It also details how to compost food waste on a large scale for hotels, restaurants, cafés and other establishments, and shows you how to plan a school or community compost scheme. An extensive list of resources, including websites, organisations, books and where to buy equipment, is also included. Beautifully illustrated with photographs throughout, this handy guide is ideal for gardeners as well as those who want to become more sustainable.

Clouds are simple enough, just a collection of ice crystals or water droplets visible to everyone. Yet they are a source of endless wonder. They appear in an infinite number of shapes and forms. Some are beautiful, some awe inspiring, and some, like the whirling funnel cloud, are terrifying. Clouds inspire artists, poets, songwriters. They have reminded astronauts, looking down from space, that Earth, a seemingly abstract orb, is a place of life and movement. those great swirls of white-as they change shape, swell, evaporate into wisps, disappear and come back, glow with sunlight or darken with rain-are a constant reminder of how dynamic our planet is.

Invisible organisms called microbes are everywhere: in soil, oceans, and snow; in the food we eat and the air we breathe - even inside our bodies. But in Antony van Leeuwenhoek's time, people believed that what they could see with their own eyes was all that existed in the world. Using microscopes of his own design, Antony discovered a living world no one had seen before. How did the simple tradesman - who didn't go to college or speak English or Latin, like all the other scientists - change everyone's minds? Proving that remarkable discoveries can come from the most unexpected people and places, this eye-opening chapter book, illustrated with lively full-color art, celebrates the power of curiosity, ingenuity, and persistence. --

The story of Doctor Who is the story of British television in the final third of the 20th century. It is also the story of the hopes and fears of generations of children - and grownups too - from the counterculture 60s to the shallow waters of the 90s. Along the way there are shock revelations, cliffhangers and liberal doses of humour; but also heartache, disappointment and death. Every taste is catered for in the world of Who. Each Doctor's era is put under the microscope with facts and informed opinion - and an in-depth reference section detailing further reading.
