Title: Physiopathies Related to Nutritional Disorders Description: Symptoms of deficiencies in various important nutrients and phytotoxicity from fertilizers and pesticide treatments are described. Pina Lorca, JA. (2009). Physiopathies Related to Nutritional Disorders. http://hdl.handle.net/10251/5679 Automatic description: This video addresses the topic of physiopathies related to nutritional disorders in citrus, focusing on mineral deficiencies and toxicities. It explains how deficiencies can be caused by a real lack of nutrients in the soil, or by problems with plant absorption due to factors such as inappropriate pH, interactions between elements, or root diseases. Symptoms usually first appear on the leaves and may require foliar analysis for diagnosis. Examples of different deficiencies are presented: nitrogen, essential for chlorophyll, a lack of which results in pale leaves; magnesium, a lack of which causes discoloration with a fir-tree pattern; and calcium, a deficiency primarily affects the tips of plant organs, causing necrosis. Iron chlorosis due to iron deficiency is also detailed, with leaves turning yellow, with only the main veins remaining green. Mineral toxicities are reflected in necrosis at the edges of leaves and can be caused by an excess of elements or salts in the soil or by inappropriate phytosanitary treatments, such as excessive use of summer oils or high-dose phytotoxic products. Finally, complex problems such as clareta in citrus are mentioned, which involves deficiencies and unbalanced relationships between calcium, magnesium, and potassium, genetic predisposition, and poor irrigation management. The video concludes with a discussion of these topics, which are essential for the agronomic management of citrus crops.
