Crop Nutrition

The rational use of fertilizers is the coefficient of multiplication of yield, improvement of quality characteristics, while at the same time it leads to the sustainability of natural resources and production. The main goal is to achieve more production with the least expenditure of inputs. To achieve this, we will we must know well the needs of our crop, its critical stages, the conditions of the microclimate, the fertility and productivity of our soils.

Both cotton and corn are two of the most economically important crops in our country. In the coming season, growers are invited to choose the type of fertilizer they will use in their crops. Knowing the needs of the crop is the key to successful yields and quality.

Although cotton is not a crop that depletes the soil of nutrients and a large part of the nutrients return with the incorporation of the plant residues of the crop, the repeated sowing in the same plots and the needs for fast vegetative growth and initiation of the biological cycle make the use of fertilizers necessary. The entire amount of phosphorus and potassium must be applied during basic fertilizing, while nitrogen by 1/2 or 1/3 in the basic and the rest superficially in 2-3 doses. It is important that the nitrogen is either in ammonia or uric form.

Maize is a nitrogen-demanding crop and the final fruit yield is directly linked to this element as more than 70% of the nitrogen taken up by the plant is removed from the field after harvest. Thus, during basic fertilization, 1/2 of the total amount of nitrogen should be applied in order to cover the needs of vegetative growth up to the application of surface fertilization. The entire amount of phosphorus and potassium should be applied during the basic fertilization.

Agrohellas recommends the types 30-10-10+0.5Zn NBPT, 20-10-10+0.5Zn NBPT, 30-10-10, 20-10-10, 30-8-12 NBPT, 30-8- 12 and START MICRO 12-43-0+Zn IPE.
