This new, fully updated and revised edition of Improved Grassland Management covers all aspects of grassland management and is of particular relevance to the UK and the Republic of Ireland, although the principles discussed apply to all temperate grassland zones. Almost twenty years ago, when the original edition of this book was written by John Frame, issues such as efficiency in the use of nutrients in manures, grassland biodiversity and greenhouse gas emissions from ruminant production were either nascent, or of no relevance to mainstream grassland farming. The intervening two decades have seen the introduction of water and, latterly, air quality directives by the EU, cross compliance, the single farm payment, and an ever-increasing need for grassland farmers to be conscious of the economics of their business. The present edition, which has been thoroughly revised by Scott Laidlaw, covers the full scope of modern grassland management. Accordingly the application of technical developments in supplying and utilizing grass and forage, which remain central to grassland management, is presented in the context of these changes.Topics covered include: breeding and evaluation of new varieties of grass to meet current needs; new technology in establishing swards; legislative constraints, background science and practice in determining forage quality and the utilization of forage either for grazing or silage; feed budgeting, grassland biodiversity, grassland and climate change, and transferring knowledge and technology; wide-ranging list of sources and references, which provides the reader with further detailed information. Essential reading for all those involved in modern grassland management including grassland farmers, agricultural consultants and advisory officers, as well as agricultural, land use and biology students. Written in a reader-friendly advisory style, it can be read and understood without an in-depth technical or scientific background. Fully illustrated with 61 colour photographs.

El análisis correcto de los datos procedentes de un experimento suele constituir una de las asignaturas pendientes de los profesionales dedicados a la agronomía, y no solo en el ámbito de la investigacion, pues pocos profesionales conresponsabilidades en la produccion agricola realizan procedimientos estadisticos sencillos para determinar si una nueva tecnica, variedad o producto mejorao no lo habitual. El valor de la experiencia para juzgar la bondad de nuevastecnicas o las ventajas de un nuevo material suele ante ponerse al rigor de unanalisis matematico, en muchas ocasiones por falta de pericia en el manejo deestos metodos. Aun cuando hay buenos libros que tratan de esta materia, son muchos los trabajos que se realizan con un planteamiento experimental y un tratamiento de los datos dudosos, y esta situacion es muy evidente cuando se evaluan Tesis Doctorales o articulos cientificos. Experimentacion Agraria trata dealiviar las dificultades que investigadores, tecnicos y estudiantes tienen sobre esta materia, describiendo de una forma sencilla y practica los metodos mascomunes utilizados en los trabajos agronomicos, sin grandes exigencias en conocimientos matematicos. El texto incluye tambien aspectos de la experimentacion agricola que escapan del ambito matematico, como los relativos a la definicion de los objetivos, la seleccion de los tratamientos, la toma de datos en campo o la interpretacion y presentacion correcta de los resultados. Se incluye tambien un glosario de terminos que resulta de utilidad para los menos familiarizados con esta materia. En resumen, se trata de una publicacion que deberia formar parte de la biblioteca de estudiantes y profesionales de la agricultura.

Land of Milk and Honey is the long-awaited sequel to Red Rag to a Bull. Author Jamie Blackett finds himself in danger of losing the family estate as his beef business encounters difficulties and the spectre of Brexit bears down on the farming community. Meanwhile he feels under threat from extreme environmentalists attacking the very concept of livestock farming and by resurgent Scottish nationalism threatening the break-up of the United Kingdom.The book is the honest and forthright account of how he copes with the crisis by following the example of New Zealand farmers in similar circumstances and successfully embracing the new creed of regenerative agriculture and switching the farm into pasture-based dairying. Through Jamies struggles the reader comes to understand the crossroads facing the British countryside as it attempts to adapt to free trade after eighty years of agricultural subsidies. We are also guided through the complexities and contradictions in the quest to reach Net Zero carbon and reverse biodiversity loss as he explores the current craze for re-wilding the land and puts some of its ideas into practice for the benefit of wildlife on the estate.Along the way Jamie becomes an outspoken newspaper columnist and establishes an unlikely political alliance with the maverick socialist George Galloway in an attempt to break the stalemate in Scottish politics and defeat Nicola Sturgeons SNP in the Holyrood election.The book contains humour, vivid passages of nature writing and numerous polemical digressions on a wide range of countryside issues.

In this historical book, the author tries to tell the audience how the occupation of the Brazilian Cerrado Biome took place, which began in the 1970s and today places Brazil as the worlds largest grain exporter. When President Juscelino Kubitschek built Brasilia, he was criticized a lot because he was building a capital in the "middle of nowhere", and it really was true. The soil, in addition to not having any fertility, had no technology to make it productive. Initially, the presidents boldness only served to show Brazilians the size of their country. Later, another visionary, also from Minas Gerais of the same lineage, Alysson Paolinelli managed to show that with technology and a lot of effort, these lands could become productive and for this he had the support of BDMG (Development Bank of Minas Gerais) that believed in his vision and took over the implementation of the various programs that served to demonstrate the feasibility of producing in the cerrado. The success of this initiative spread throughout Brazil, where the Cerrado Biome existed. The book also shows that all this growth in our agricultural production took place with only eight hundred, twenty thousand properties out of a total of five million, five hundred thousand that Brazil owns. The book also describes the various failed initiatives to occupy Brazilian soil, including the Amazon biome. Finally, the book shows that the occupation of the cerrado served as a real shield to divert the focus from the dangerous occupation of the Amazon in the same way it was being done.Alysson PaolinelliThe recent nominee to the Nobel Peace Prize is also the author of the Foreword of this book

A terrific book Michael MorpurgoExcellent Helen CzerskiA clear, concise and accessible guide to the pivotal question of our age Guy Shrubsole We need land for so many of humanitys growing needs, such as food, renewable energy, carbon storage and housing. Traditionally, weve stolen it from nature, but this has led to a mounting toll of extinction and pollution that is now punishing us. So, as theres no land left to take, how do we get more from the same, or preferably less. In Land Smart, Tom Heap, a presenter on BBC TVs Countryfile, Radio 4s new Rare Earth series and the anchor of The Climate Show on Sky News, tours the British countryside meeting the farmers, scientists, conservationists and even warehouse managers who are solving the most pressing challenges facing our countryside and the world. If we use land cleverly it can give both humanity and nature the space to thrive on just the one planet. If not, were in trouble.

FROM THE BESTSELLING AUTHOR OF THE SECRET LIFE OF COWSElegiac, funny, warm and wise, The Wisdom of Sheep will delight country folk and city dwellers alike. KATHERINE MAYA wonderful antidote to the hectic pace of modern life. JAMES OSWALDWe talk about people behaving like sheep, which assumes that sheep all behave in the same way. That has not been my experience.Some are affectionate, others prone to head-butting. Some are determinedly self-sufficient, others seek our help when they need it. And some can be trusted to lead the flock home. They are as individual as we are. Farm animals are familiar to us from childhood stories, but little did we know that their inner lives are full of complexity, deep bonds and family dramas. Rosamund Young has been an organic farmer for over forty years and this is her record of a life at the beck and call of the animals while observing and preserving the abundant wildlife at Kites Nest Farm. It is a story of joy, discovery, cooperation and sometimes heartbreak. We learn about sheep growing old disgracefully, the intelligence of supposedly bird-brained hens, conversations between cows and why you should never send a text whilst milking . . .Delightful. ALAN BENNETT, ON THE SECRET LIFE OF COWS

True, unflinching, powerful, lyrical Kate MosseIts quite an achievement to shine a light of truth on the often idealised, always understated, role of the farmers wife.RAYNOR WINNWonderful, inviting, wholesome.ObserverVery moving, real and true.AMY LIPTROTEnchanting, funny, fearless. . . a luminously beautiful memoir.SpectatorBeautiful and very honest.CAITLIN MORANAuthentic and affecting.SARAH LANGFORD Lovely, warm and real, it made me cry and cook and think. ELLA RISBRIDGERA portrait of life at Helen Rebanks Lake District farmhouse that beautifully captures the unsung work of keeping a home and raising a family. As dawn breaks on the farm, Helen Rebanks makes a mug of tea, relishing the few minutes of quiet before the house stirs. Within the hour the sounds of her husband, James, and their four children will fill the kitchen. There are also six sheepdogs, two ponies, 20 chickens, 50 cattle and 500 sheep to care for. Helen is a farmers wife. Hers is a story that is rarely told, despite being one we think we know. Weaving past and present, Helen shares the days that have shaped her. This is the truth of those days: from steering the family through the Beast from the East and the local authority planning committee, to finding the quiet strength to keep going, when supper is yet to be started, another delivery man has assumed he needs to speak to the man of the house, and she would rather punch a cushion than plump it. This beautifully-illustrated memoir, which takes place across one day at the farm, offers a chance to think about where our food comes from and who puts it on the table. Helens recipes, lists and gentle wisdom helps us to get through our days, whatever they throw at us.Readers love The Farmers WifeLovely. . . the book equivalent of getting up before everyone else to enjoy the silence of the day.Evocative and thought-provoking. . . a beautiful, lyrical read that gives voice to the pushes and pulls of everyday life.A beautifully written manifesto for the life shes chosen to leadA beacon of light. . . Ive never read a memoir quite like this.
