Potassium is an abundant element in nature (in terms of cations, it is the most abundant), which is often detected at high concentrations, greater than 150 ppm, in chemical soil analyses. However, as in the case of other elements, Potassium is not completely assimilable, there is a mineral fraction not available for the plant in …
Saline and sodic soils are the result of the accumulation of soluble salts and exchangeable sodium. For these problems to occur, there must be a generally constant rate of accumulation of salts and sodium; phenomenon that usually occurs in lowlands, where there is accumulation of runoff and poor drainage at one time of the year …

Stress is identified as a significant deviation from optimal conditions for life. These conditions cause changes in all functional levels of organisms. From a biological point of view, stress has a broader connotation, referring to environmental changes that alter the physiological state of plants (Larcher, 1995). Types of stress in plants Now, there are different …
There is a growing need in the world to produce more food for the growing population; this, of course, is not an easy task since we are facing a trend of scarcity of natural resources available to carry out this work, from lack of water, pollution, climate change, the frequent scourge of pests and diseases …
All vegetables perform two survival mechanisms during post-harvest; Breathing and Perspiration, these allow them to use the nutritional reserves to cover the metabolic energy requirements (ATP). Specifically, respiration achieves obtaining ATP, however, during the time it remains in storage places, and due to unavoidable physical forces, the water that makes up the structure of each …
