The cereal season has been affected by the increase in fertilizer prices and costs related to the agricultural sector. As a consequence of this situation, many farmers have had to do without bottom and top dressing fertilizers. Therefore, from Agran we recommend X-Tend, an effective solution that makes the most of soil nutrients and achieves very productive results.
X-Tend is a liquid biostimulant developed in the United States based on Micro Carbon Technology. It can be mixed with solid and liquid fertilizers to achieve a higher percentage of nutrients absorbed by the plant, greater root development and less sensitivity to drought and weather conditions.
When the product is applied to the soil and roots, signals are activated in the plant that promote the massive entry of nutrients into the interior of the cells, with special emphasis on nitrogen in the form of nitrate and phosphorus. Thus, the cereal has greater resources to produce sugars, proteins and carbohydrates, achieving more productive crops and a positive return on investment for the farmer.
The benefits on the plant are observed from the first weeks of application, where the differences between treated and untreated cereals are clearly visible. Stronger, greener and denser plants that stoically withstand any kind of stress and have more energy available to produce more and better.
Agran points out the importance of using advanced carbon technologies as a source to protect and improve the fertility of agricultural land.
It is very important to feed our soils with tools that allow us to multiply their native microbiology, reducing the fragility of cereals to weather changes, drought or stress caused by pests and diseases.
With more efficient fertilizer management and continuous soil enrichment, a multiplier effect is achieved. This makes it possible to progressively increase production after each season.

El Boro y el molibdeno es un micronutriente fundamental tanto para la sandía como para el melón ya que interviene, entre otras, en la floración, el tamaño, la fertilidad o la calidad de los frutos.
Boramol es una suspensión concentrada de boro y molibdeno diseñada para aportar ambos micronutrientes en la fase de prefloración, floración y formación de frutos. En esta etapa, las necesidades de boro son mucho más altas que está vinculado con una mayor calidad de polen y acumulación de reservas energéticas.
La aplicación en fertirrigación de Boramol ofrece las siguientes ventajas en melón y sandía:
Gracias al aporte de estos micronutrientes, se obtiene un mayor porcentaje de cuaje y la calidad de los frutos se ve aumentada.
Citrus budbreak is the most important moment in the beginning of the crop and, in the case of citrus, spring budbreak is crucial. This is so because, depending on how it has developed, the productivity and quality of the fruit can achieve greater or lesser efficiency. In other words, the more bud break, the better the harvest results.
For all these reasons, it is recommended to apply stimulating solutions after harvesting the fruit in order to obtain the best possible sprouting for the following production.
There are several factors involved in citrus sprouting:
In that sense, the residence time is the most important because the fruits promote gibberellin synthesis and bud transport, thus preventing sprouting and altering differentiation.
Velocity is a 15-5-5 NPK solution with micronutrients indicated for foliar application from the early stages of crop development.
In addition, it provides a great stimulus in the crop, increasing cell hydration and the beginning of sprouting processes. It promotes the increase of reserves, available energy and final production.
Application advantages of Velocity:
For citrus, Velocity requiresapplications every 30 days in mixture with the phytosanitary treatments and in doses of 5-10 L/ha from sprouting.

The optimum growing temperature for berries ranges between 23 and 25 ºC. However, most varieties, such as strawberries, need cold winter temperatures to achieve good production results.
Thus, as far as cultivation is concerned, berries require loose soils in which there are no problems of waterlogging, as this can lead to the rapid death of a large number of plants. And, if we talk about fertilization, do not overdo it with the amounts because these plants are sensitive to salinity.
In addition, another peculiarity of berries, and in particular strawberries, is that they are very demanding in terms of pH. This is due to the fact that these crops do not tolerate calcareous or very low pH soils.
Of all strawberry crops, berries require more specific soils. For this reason, it is important to control soil moisture so that the crop can grow in good conditions and quickly.
To achieve high yields, strawberries are sensitive to stimulant treatments that favor continuous flower production and initial fruit set. For this reason, Agran recommends the use of Breakout.
The use of Breakout is recommended in moments or phenological phases of the crop where it is desired to stimulate the natural production of phytohormones related to auxins and cytokinins, such as sprouting, bud formation and flowering.
In addition, thanks to the phosphorus complexed with Micro Carbon Technology it contains, it provides the necessary stimulus to increase the metabolic and photosynthetic rate of the crop and to favor the emergence from dormancy and environmental stress.
In this sense, the advantages that Breakout brings to berry cultivation are fundamental.
👉 Stimulates bud outgrowth, lateral growth of stems and leaves and increases the vegetative density of the crop.
👉 It boosts flowering and homogeneous flower emergence, improving pollen quality and fertilization.
👉 Increases the thickness and length of the petiole, allowing the fruit to increase its exposure to light, fatten and ripen faster.
It is compatible with insecticide, phytosanitary applications and copper formulations.
🌱 ➡️ BREAKOUT: Phenological enhancer based on natural induction of cytokines and auxins.
Autumn is the ideal time to carry out both the ripening and harvesting of citrus fruits. Oranges, tangerines, grapefruit, lemons or clementines are fruits that find their ideal season with the cold and with the farewell of summer.
The Organization of Consumers and Users (OCU) includes the entire citrus family in the best foods for this season. Its vitamin and mineral contribution makes citrus a vital food to overcome the autumn day to day.
Arriving at this time of the year with citrus fruits ready for harvesting is essential. That is why, in this article we tell you how in Agran.es you will find the necessary impulse for citrus fruits to be one hundred percent ready.
The ripening process is the most important step prior to harvesting. Controlling even the smallest detail can make a difference in order to have a spectacular product. To achieve this, Agran.es recommends the use of Fructus.
The mixture of phosphorus and potassium makes this liquid solution an element that helps to accelerate and promote the fattening process. In addition, itactivates and induces ripening by increasing the firmness or hardness values of the fruits themselves.
Despite these advantages, Fructus is a very simple product to use. Fully liquid, Fructus is easy and safe to use. In addition, it contains no sulfates, no chlorides and no nitrates.
If the maturation process is vital, it is also vital to know how to use this type of product in the right measure.
In the case of citrus, the recommended dose is divided into two parts. The first one depends on whether we make a foliar application. In that sense, the most correct use is between 2 or 4 applications of 300 or 500 cc/hl per season every 20 days from the beginning of the fruit development process.
FRUCTUS: highly concentrated liquid solution of phosphorus and potassium
Summer crops such as fruit trees, melon and watermelon or industrial tomatoes are characterized by an important dependence on the sugar content of the fruit. These are known as º Brix, a factor that serves to know the total percentage of dry matter (generally sugars such as sucrose) and that we can measure in the fruit, the sap of the plant or even the soil. In this article we tell you what mechanisms are involved and how to increase the sugar content in fruits.
Potassium has always been linked to sugar production and production and transport of sugarsThe reality is that there are many more factors involved in obtaining a higher amount of sugar (º Brix) and increased sweetness in the fruit.
The process of production of sugars and photoassimilates by the plant is quite complex and requires the synchronization of many enzymes, biological and photosynthetic processes. Although many times attempts have been made to advance the process with the exogenous application of sugars (table sugar, for example), the reality tells us that positive results are not obtained.
At the biochemical level, the plant obtains sugars from the photosynthesis process, transforming starch and fructans into sugars such as sucrose from the enzyme amylase. However, this process slows down if the levels of potassium, boron or phosphorus, among others, are not at optimal levels and readily available to the plant.
In order to know how to increase the sugar content in fruits, it is necessary and essential to know the importance of the following elements.
It is not an element in the periodic table, but it is one of the most important factors in the manufacture of sugars. Light, together with water, favors photosynthesis processes, without which nutrients would cease to be important. The combination of good lighting and proper nutrition allows maximum yields to be obtained.
Phosphorus is involved in the manufacture of energy within the plant, being an indispensable component in obtaining cellular energy (ATP). Therefore, it is involved in the manufacture of sugars and has special importance in obtaining º Brix by the plant.
Potassium is the element that regulates the water balance of the plant. Its contribution ensures high yields in the crop and is involved both in the production of sugars and in their transport to the root and fruit.
This element is responsible for the production of antioxidant substances and elements that give color to fruits, such as lycopene in industrial tomatoes.
Boron is a microelement that regulates phytohormone activity and is involved in the movement of sugars to the fruit and root. Therefore, it is important to combine phosphorus, boron and potassium nutrition at ripening to achieve the highest possible sugar accumulation.
Subsequently, this element helps in the mobility of photoassimilates to the roots to generate reserves for next year, in the case of tree crops.
At times when nutrition does not provide maximum results, the use of specific biostimulants and correctors can meet the crop's demand at specific times.
SUPER K: potassium 40% w/w complexed with Micro Carbon Technology special fertigation technology
PHOS-MAX: ultra-concentrated phosphorus complexed with Micro Carbon Technology to promote energy transfer (ATP) and manufacture sugars
COLORO: potassium 20% w/w with fattening and ripening inducers (cytokinins and gibberellins) and certified organic.
YIELD-MAX: maturation enhancer with abscisic acid precursors.
FRUCTUS: phosphorus (23.5% w/w) + potassium (26.0%) liquid and ultra concentrated with cell filling precursors.
BORAMOL: boron (9.0% w/w) + molybdenum (0.75% w/w) sugar mobilizer.
If we detect a low presence of sugars in the sap (measured with a refractometer in petiole) and the weather is suitable, we recommend the application of the following corrective treatment
If we want to act with everything to promote a rapid rise in Brix, we will apply phosphorus, potassium and boron together.
At the same time, if potassium levels in the plant are low, we will help to maintain adequate levels with the following treatment:
If we work in organic agriculture, we will use COLORO (300-500 cc/hl) in foliar application or 3-5 L/ha in fertigation.

Por ello, en el blog de hoy vamos a hablar de la importancia de los prebióticos en la agricultura.Seguir leyendo
There are several causes that affect water scarcity such as climate change, contamination of water resources, population growth or water stress, among others. So, in today's blog we talk about how to optimize irrigation with the use of surfactants.
Farmers in southern Spain are uncertain about the amount of irrigation water they will have available for each season. Thus, the main problem facing irrigation management is water scarcity . This means that farmers are unable to organize their crop cycle and meet market demand.
Currently, agriculture is subject to the availability of water, both in terms of quality and quantity. Therefore, it is interesting to apply strategies to increase the efficiency and availability of water, highlighting the use of surfactant as an optimal solution to the present problems.
Soils are characterized as hydrophobic and this is a limitation in the development of the crop because water penetration decreases, as well as the supply of nutrients to the root system. This penetration is limited by the surface tension of the water. Therefore, the use of surfactants reduces or eliminates this tension and water penetrates better to the surface.
Surfactants are known as adjuvants that reduce the strength of the surface tension of water by decreasing the energy of the bonds between water molecules, thereby increasing root system and nutrient uptake.
In agriculture, the application of surfactants has been gaining relevance due to their coadjuvant properties. Their main function is to increase the contact surface between the solid-liquid phases through wetting.
In general, we can divide between surfactants for foliar application (they modify the relationship between leaf surfaces and spray droplets) and surfactants for irrigation application (they improve soil penetration).
All of them will improve dispersion, emulsification, spreading, adhesion and wetting by modifying the behavior of liquids on the surface.
Surfactants have several advantages, the most important being:
In general, it favors cultivation and increases production.
There are different surfactant raw materials and none of them can be considered as ideal, for each moment of the crop it will be necessary to apply one according to the climatic conditions at that moment and also to what is to be controlled.
Surf-Max, surfactant technology for lateral water movementThe versatility of the product allows it to be mixed directly in the fertilizer tanks, so that we can dose so that each drop of nutrient irrigation contains a sufficient part of surfactant technology. This option reduces handling operations and eliminates the need for spot applications (e.g., monthly), which lose efficiency and reduce (but do not avoid) the usual problems derived from soils with low water mobility and very hydrophobic soils.
Surf-Max acts directly on the irrigation water improving its transport and movement in the soil . As a result, it is able to cover a larger area both vertically and horizontally, enveloping all the roots. In addition, by eliminating the hydrophobicity of water in the soil, it circulates freely through the wet bulb of the plant, increasing its surface area and allowing a greater assimilation of water with nutrients.
These properties given to water and its movement in the soil can allow savings of up to 20-25% with the same productive result.
It has several benefits:
