Opis

This book explains the use of an ecological way of farming, with modern practical applications, to make the fullest use of land resources and the best utilization of available capital and labour. In analyzing the vital relationship between soil, plant, animal and man, the author discusses the best care of land itself, its components, grassland management and the most efficient use of crops to maximize yield, food quality and profitability without the extensive use of chemicals and without damaging the ecology. Widdowson also covers the holistic approach to animal farming, the welfare and health of poultry, cattle, sheep and goats, their nutritional needs through the various stages of their lives, and the best way to balance their diets.
