Book excerpt: Aquaculture pond managers measure water-quality variables and attempt to maintain them within optimal ranges for shrimp and fish, but surprisingly little attention is paid to pond soil condition. Soil-water interactions can strongly impact water quality, and soil factors should be considered in aquaculture pond management. The importance of soils in pond management will be illustrated with an example from pond fertilization and another from aeration. Pond fertilization may not produce phytoplankton blooms in acidic ponds. Total alkalinity is too low to provide adequate carbon dioxide for photosynthesis, and acidic soils adsorb phosphate added in fertilizer before phytoplankton can use it. Agricultural lime stone application can raise total alkalinity and neutralize soil acidity. The amount of limestone necessary to cause these changes in a pond depends on the base unsaturation and exchange acidity of the bottom soil. Two ponds with the same total alkalinity and soil pH may require vastly different quantities of limestone because they differ in exchange acidity. Aeration enhances dissolved oxygen concentrations in pond water and permits greater feed inputs to enhance fish or shrimp production. As feeding rates are raised, organic matter accumulates in pond soils. In ponds with very high feeding rates, aeration may supply enough dissolved oxygen in the water column for fish or shrimp, but it may be impossible to maintain aerobic conditions in the surface layers of pond soil. Toxic metabolites produced by microorganisms in anaerobic soils may enter the pond water and harm fish or shrimp.

Book excerpt: "It's up to every single one of us to do our bit for wildlife, however small our gardens, and The Butterfly Brothers know just how that can be achieved." Alan Titchmarsh Join the rewilding movement and share your outdoor space with nature. We all have the potential to make the world a little greener. Wild Your Garden, written by Jim and Joel Ashton (aka "The Butterfly Brothers"), shows you how to create a garden that can help boost local biodiversity. Transform a paved-over yard into a lush oasis, create refuges to welcome and support native species, or turn a high-maintenance lawn into a nectar-rich mini-meadow to attract bees and butterflies. You don't need specialist knowledge or acres of land. If you have any outdoor space, you can make a difference to local wildlife, and reduce your carbon footprint, too. "Wildlife gardening is one of the most important things you can do as an individual for increasing biodiversity and mitigating the effects of climate change. From digging a pond to planting a native hedge, the Butterfly Brothers can help you every step of the way." Kate Bradbury

Available in PDF, EPUB and Kindle. Book excerpt: They said her grandfather was dead. They said her grandmother was crazy. Christy knows they're wrong. When her grandmother dies, 13-year-old Christy inherits an old family secret: the pond behind her house is in fact a portal to another world. What’s more, she learns that her grandfather went through the portal when he mysteriously “disappeared” nine years ago. Christy tries to respect her grandmother’s final wishes and not go exploring, but when a classmate named Rob falls into the pond, she has to act. Since no one would believe her if she told them the truth about the pond, Christy arranges her own rescue party. In order to rescue Rob, she’ll have to brave a bizarre alien landscape, evade hostile creatures, and protect Danny, the boy from next door who followed her through the portal. Meanwhile on Earth, the grown-ups launch a frantic search, and they’re willing to drain the pond to find out what happened. Will Christy be able to find her grandfather, rescue Rob, and return safely to Earth before she becomes a permanent resident of the Empty World? Portal Through the Pond is the first book of the Empty World Saga, a science fiction adventure series for kids aged 8-12. If your kids have blown through the Land of Stories, devoured the Keeper of the Lost Cities, or can't wait for the next Wings of Fire, make the complete Empty World Saga their next read. Pick up your copy of Portal Through the Pond, and land in an alien world!
