Paperback. Condizione: New. Print on Demand. This book delves into the availability of soil potash in clay and clay loam soils. The author conducted a series of experiments over several years to determine if natural potash compounds could provide enough nutrients for grass crops without additional fertilization. The study found that these soils contained significant amounts of potash that were gradually released over time, fulfilling the nutritional demands of grasses. The author also explored the effects of lime and gypsum on potash availability, discovering that lime did not increase solubility but could influence the movement of water in the soil. Furthermore, the experiments revealed that added potash fertilizers were largely absorbed by the soil, preventing significant leaching. Through detailed analyses and field observations, this book provides valuable insights into the complex relationship between soil chemistry, plant nutrition, and agricultural practices, offering practical guidance for farmers and landowners seeking to optimize soil fertility and crop yields.
