The effects of different water quality parameters on aquacultured species and how to measure and maintain these parameters at optimum levels are discussed.

As much as 12% of the world's soils may suffer excess water so that flooding is a major limiting factor on crop production in many areas. Plants attempt to deal with submergence by forming root aerenchyma to facilitate oxygen diffusion from the shoot to the root, initiating a hyponastic response...

In growing cereal and legume seedlings arsenate is more toxic for root growth than shoot growth. Arsenate treatment affects the activity of antioxidant scavenging enzymes, level of oxidative stress markers, sugar and starch contents as well as carbohydrate metabolizing enzyme activities causing...

L-Arginine (L-Arg) is a semi-essential amino acid that is a natural constituent of most dietary proteins in our daily diet. A fundamental function of this amino acid is its role as the substrate for the synthesis of the signalling molecule nitric oxide (NO). As NO regulates a variety of...

This chapter discusses the main drivers and extent of N losses by leaching of mineral N (inorganic N as ammonium, nitrite and nitrate) and the effect of management practices on reducing N leaching from grasslands, with emphasis on grazed systems. The main drivers of the potential for mineral N...

This chapter discusses the toxic effects of several compounds that are formed during food processing or improper food storage, including those of acrylamide, nitrite and nitrosamines, trans fatty acids, polycyclic aromatic hydrocarbons, heterocyclic aromatic amines, glucose-derived glycation...

The characteristics of nitrate and nitrite poisoning outbreaks in cattle in Santa Catarina, Brazil, fed with oats (Avena sativa) and ryegrass (Lolium multiflorum) [date not given] are described.

This chapter covers the different causes of poisoning and sudden death in pigs. The toxicity, symptoms, diagnosis and treatment of mycotoxins, plant toxins, drugs and chemical poisons are discussed as well as that of the non-infectious and infectious causes of sudden death.

This chapter discusses the diagnosis and treatment of poisoning in goats in sheep raised in UK, emphasis focused on the three causes of poisoning namely poisonous plants, chemicals, and pesticides.

This chapter presents the poisonous plants affecting livestock in Central America, with emphasis on Panama. The data presented here were obtained from field surveys and necropsies in 1994-95, 2000-01 and 2009. Only plants that induce spontaneous intoxication on livestock raised under range...
