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 …
Sodium (Na) is an abundant element in the natural environment and, like other elements that belong to the same group, it is not found in an elemental state because it reacts quickly with non-metals. Deficiency Sodium (Na) in addition to being a detrimental element for the soil structure, due to the dispersing effect of its …
Nematodes are tiny worm-like critters that live in the soil. Most of these organisms do not represent any threat to agriculture, since they feed on fungi, bacteria and other organisms. However, there are some that do represent a risk for vegetable production because they feed on their roots. Problems caused by nematodes. Nematodes manage to …
Calcium is an element that is absorbed in the form of divalent Calcium cation (Ca2+) and is abundant in the soil, however, at certain stages of crop development, plants may express symptoms of deficiency of said element. Calcium is absorbed through the tissue of “tender” roots. This is one of the main reasons for calcium …
Chlorine (Cl) is an essential element for plants, but it is required in very small quantities. Depending on the culture and its phonological stage, the Chlorine content in the tissue will be variable. Chlorine (Cl) toxicity manifests itself with burns on the margins of the leaves, premature yellowing, bronzing, even leaf drop. Among the most …
Humic Acids. Are complex organic molecules formed by the decomposition of organic matter. These directly influence the fertility of the soil, while contributing significantly to its stability, influencing the absorption of nutrients and, as a direct consequence, the exceptional growth of the plant. Fulvic acids. They are molecules of low molecular weight, extremely complex, soluble …
Sodic saline soils It is important to differentiate between saline and sodic soils. Saline soils are those that contain significant amounts of salts more soluble than gypsum, which interferes with the growth of most sensitive crops and plants. Salinity is measured by Electrical Conductivity (EC). In contrast, sodium soils originate when the monovalent sodium ion …
Electrical conductivity is the most extended and widely used parameter in salinity estimation. It is based on the speed with which the electric current passes through a salt solution, which is proportional to the concentration of salts in solution. Until a few years ago it was expressed in mmhos/cm. It is currently expressed in dS/m …
In a botanical sense, the fruits that are harvested and that we consume are fertilized ovaries (from the flower in angiosperms). The fruits give rise to and protect the seeds until the moment of maturity and dispersion, which is when the seed, by some means, leaves the fruit and is viable to perpetuate the species …
Soils often have poor oxygen levels on farmland. The condition in the rhizosphere region of arable land with shallow irrigation results in reduced root growth, poor field performance and reduced plant yield. Therefore, to help grow berries in soils with optimal water use, the application of hydrogen peroxide (H2O2) is an efficient way to impart …
