Abstract

A great deal of researches reveals that the presence of weeds modifies the chemistry and fertility of soil environment. The chemistry and fertility of soils affected by weeds may include soil reaction and other soil properties affected by the changes in soil pH like soil cation exchange capacity, the soil enzymatic activities such as those of phosphatases, ureases, arylsulfatases, and b-glucosidases, the soil exchangeable potassium, the soil organic carbon, phosphorus, nitrogen, and sulfur contents, and the heavy metal solubility. This book deals with these kinds of soil chemical and fertility properties under various tropical weeds mostly investigated in the Province of Lampung Indonesia. This book is organized into nine chapters. Chapter 1 (Introduction) briefly focuses on the interrelationship between the chemistry of soils and the existence of plants and weeds in the soil environment. Chapter 2 (The Soil – Weed Interrelationships) describes more specifically the interrelationship between the chemistry of soils and the growth of weeds while Chapter 3 (The Important Facts about Tropical Weeds) briefly describes the important weeds of the tropics: their concepts, their effects, invasion and dominance, and their control and management. Chapters 4 - 9 deal with the effects of weed presence on the chemistry and fertility of soils that include soil pH and soil enzymatic activities (Chapter 4: Effects of Forest Conversion, Chapter 5: Effects of Tropical Weeds on Soil pH and Enzymatic Activities), soil contents of carbon, phosphorus, and sulfur(Chapter 6: Effects of Tropical Weeds on Soil Carbon, Nitrogen, Phosphorus, and Sulfur), soil exchangeable potassium (Chapter 7: Effects of Tropical Weeds on Soil Potassium), and heavy metals (Chapter 8: Effects of Tropical Weeds on Heavy Metals). Chapter 9 (Closing Remarks) highlights some important conclusions related to the effect of weed existence on the chemistry and fertility of soils.
