We are in times of frost in our latitude, and it is time to think about viable solutions to avoid as far as possible the damage they cause.

Frost Defense is a liquid product based on organic acids that covers the outer surface of plants, preventing the loss of water due to low temperatures and minimizing the damage caused by these adverse conditions.

FROST DEFENCE is indicated to protect our crops from radiation frost, and protects the plant (especially flowers and fruits) up to a temperature of -3ºC and for approximately 10 days.

It is advisable to apply FROST DEFENCE 24-48 hours before the frost forecast. The product is degraded without affecting the quality of the fruits and without harming the plant in any way.

The existence of elements such as Iron, Zinc, Manganese or Copper in the earth crust is abundant. On the other hand, many of our crops show deficiencies of these and other elements. For example, Iron in one of the elements which can be found in higher levels in soil, with a 3.8% average. However, ferric chlorosis is one of our most common problems in the field.

There are several causes that explain why Iron is not available for plants:

– The biggest percentage of Iron found in soil is Fe+3. This form is the least assimilated by the roots.

– Furthermore, as the pH in the soil increases, this form precipitates being no longer available.

– Low temperatures, an excess of phosphorus and an excess of heavy metals also contribute to lower the availability of Iron.

Plants have to two strategies through which they are capable of increasing the availability of Iron in the soil solution:

– Monocots non-gramineous and dicotyls can lower the pH of the rhizosphere, so Fe+3 solubilizes and promotes the reduction to Fe+2, which is available for the plants.

– Gramineous plants excreet phytosiderophores which solubilize Fe+3 ions, forming a complex Fe- phytosiderophores.

The use of chelates is the most efficient way of correcting ferric chlorosis and other nutritional deficiencies. Chelates are a chemical compound in which an organic molecule surrounds and links through different points to a metallic ion, protecting it from any exterior action, avoiding its hydrolysis and precipitation.

For explaining it in a simple way, a chelate is a substance which joins to Iron or any other metal, helping its easier absorption by the plant.

The mode of action of the chelate goes as follows:

a) It increases Iron solubilisation.

b) It transports Iron towards the roots of the plants.

c) It gives away Iron to the plant.

d) The organic part of the chelate goes back to the soil for solubilising more Iron.

In Adler Agro we have a wide range of chelates, in between them we can highlight Fe EDDHA 4.8 o-o. In between its characteristics, it stands out its high stability that keeps Iron available for the plants during a long time, correcting iron deficiencies in the crops.

Adler Agro, constantly innovating, releases three new products with which give efficient solutions to farmers.

Amino

Amino is a high-quality product, formulated with synthesis amino acids, and particularly suitable for helping the plant overcome stressful moments produced by external factors, such as droughts, frosts, etc.

Amino Start

Amino Start is a product based on amino acids with NPK. Its application improves the crops vegetative development, in particular extensive crops, cereals, oilseeds, etc., providing the crop with the essential nutrients needed for a correct development during its first stages up to blooming stage.

Amino Set

Is an other product specially formulated for extensive crops, cereals, oilseeds, etc., but in this case it improves grain or fruit fattening. It must be applied during setting and fattening stages of the seed.

With this three products, Adler Agro has a wide range of products with amino acids, embracing nutritional needs of the most representative crops.
