Corn is the most cultivated cereal worldwide and two thirds are used for animal feed.
In Asturias, we use corn as one of the main sources of energy for livestock feed, either as silage (a good quality corn silage can provide 80% of the energy requirements of cattle), or used grain for the production of feed.
This means that a good management of this crop can represent an asset of great importance in the economic result of our farms.
At Campoastur we base the corn campaign on a comprehensive service, which goes from sowing to harvesting forage, looking for products and services that adapt to the personalized needs of each farm. For this we have a large machinery park and a multidisciplinary technical team made up of professionals with extensive experience. We have the answer in each phase of cultivation, we advise and help our partners by putting at their disposal the latest news in the service of machinery, fertilizers, seeds and phytosanitary products.
It is the cereal crop that uses sunlight more efficiently, because it has a very efficient photosynthesis process, compared to other crops such as wheat.
Generally, it is sown in spring and depending on climatic conditions, soil, management and variety, maturity is reached between 60-180 days after the emergence of the plant.
It is necessary that the soils have the sufficient temperature (tempero) to ensure a good emergence and that it does not slow down growth. The minimum temperature for germination is 10ºC, and at a soil temperature of 16-18ºC, corn normally emerges the week after sowing. In cold conditions, plant emergence is slow and development is hampered by poor availability of nutrients, especially Phosphorous and Zinc.
The corn plant has a well-branched root system that mostly develops in the first 70 cm from the ground. After the appearance of the plume, adventitious roots are also formed above the ground (anchor, or struts) that serve both to support the weight of the plant and to absorb nutrients.
Water stress before the appearance of the plume can cause a reduction in yield of between 10 and 40%; however, corn does not tolerate waterlogging and good soil drainage is essential.
In the initial stages of plant development, growth is limited by the size of the leaves and the root system, therefore it is necessary that there is good availability of all nutrients at that time, if not, the final yield it will be reduced.
The optimal soil pH is between 6 and 7.2. Corn has a low tolerance to low pH soils, due to the toxicities of Aluminum and Manganese. Zinc, Manganese and Iron deficiencies can occur at pH levels above 7.5. An adequate soil pH facilitates a good availability of nutrients and maximizes growth.
The use of products such as Magnical (available in Campoastur), help us to raise the pH of the soil, improve the structure, increase the yield of the crop, and enhance the root system. In addition, sulfur forms complexes with free aluminum, reducing the toxicity of plants.
Soil pH also affects herbicide activity, they are more effective when the pH is between 5.8 and 6.5. Weed control is essential to ensure a successful and competitive start to the crop says rotavator parts manufacturers in ludhiana.

Herbicide and phytosanitary application service
The machinery service with the TECNOMA LASER 3000 self-propelled sprayer has the most advanced machinery for the application of herbicides and phytosanitary treatments in corn and pastures. The TECNOMA LASER 3000 has a working width of 28 meters and a capacity of 3,000 liters with the two lateral arms deployed, it represents an innovation in the Asturian field, being this a highly efficient and technologically unique machine.
The entry into force of RD 1311/2012 on the sustainable use of phytosanitary products highlights the concern on the part of the general population about the risks and effects of these products on human health and the environment.
Campoastur, in its commitment to rural areas, offers its partners a new application service for phytosanitary products supervised by specialist technicians with extensive experience in crops.
Nutrients needed in corn
Nitrogen.- Ensures good yields. It is involved in the development of crops, and has to be readily available.
Phosphorus.- Especially important for the development of the roots and establishment of the crop, it advances the maturation for an ideal harvest.
Potassium.- Like Nitrogen, it promotes crop development and growing plants absorb it in large quantities. It must be balanced with nitrogen. It helps to minimize the effects of frost and reduces lodging.
Magnesium, Sulfur and Iron.- They increase photosynthetic activity, maintaining the growth necessary to obtain high yields.
Calcium.- Intervenes in the production of roots, leaves and stem.
Sulfur.- Antagonic in divisions with Calcium and Magnesium. Important to ensure the effectiveness of Nitrogen
Boron.- Necessary for a good curdling of the grain.
Zinc. Important for photosynthetic activity.
Copper, Manganese, Iron and Molybdenum.
Use of manure and slurry
Manure and animal slurry provide valuable nutrients, contributing at the same time to increase the organic matter content of the soil. Care must be taken when applying it as only 50-70% of the nitrogen it provides will be available to plants the first year. If applications greater than the necessary nitrogen are used in a year, a quantity of phosphates greater than the needs of the crop will also be supplied, which can restrict the absorption of zinc, and in these cases the contributions of zinc in foliar or seed application , They are fundamental.
Use of Fertilizers
A good integral and personalized fertilization that avoids the lack of nutrients, increases the yield.
As a general rule, a typical bottom fertilizer would be: 150 kgr N / Ha, up to 150 kgr P2O5 / Ha, and up to 150 kgr K2O / Ha.
Fertilizer application, – broadcast, – in bands
Starter fertilizers, Starters, with localized application – Pop Up, or with precise application together with the seeds.
Foliar applications, increase growth and solve an immediate nutritional need (zinc deficiencies) and can be done when a sufficient foliar surface is available, in combination with compatible herbicides.
In Campoastur we have the most adequate and complete range of fertilizers for corn. Our objective is to obtain the best performance and the best quality of the forage optimizing the costs of fertilizer.
