The presence of both Nitrogen forms in the soil and the sufficient supply to the plants in a regular pattern corresponding to their needs, constitute the "key of success" for the yield increase and the production quality.
With "traditional" fertilizers, the adaptation of fertilization to the needs of the culture is not feasible. The Nitrogen supply deviates from the plants requirements and fertilization is accompanied by a large loss of fertilizer to the deeper soil layers and to the atmosphere.
Nutractive® new generation fertilizers, prevent fertilizer losses, "stabilize" Nitrogen in the soil and extend its availability to the culture for a long period of time.
Via the nitrification retardant DCD, they alter the Nitrification rate, regulate Nitrogen supply based on the culture requirements and ensure continuous supply to the plants during the entire farming period.
With Nutractive® fertilizers, the dynamic process between the fertilizer and the culture is restored. The fertilization is adapted to the specific requirements of the plants, its effectiveness is increased whilst completed nutrition and high culture productivity is achieved.
Nitrogen, an important nutrient
Nitrogen, along with water, is the most important nutrient for the plants and it is characterized as the "Regulator" of vegetation and fruitation.
It passes through the farming ecosystem in many chemical forms that exhibit continuous transformation, high mobility and different degrees of utilization from the plants.
Nitrogen deficiency leads to reduction of soil fertility, impaired growth, premature ageing of plants, production reduction and quality deterioration.
Its abundance favours the production of plants prone to illnesses and environmental conditions, delays flowering, decreases boll retention, delays maturation and has a detrimental effect on the production.
Nitrogen sufficiency and rational management constitute the more important factor for the robustness and the productivity of cultures, in modern agriculture.
With traditional fertilizers, Nitrogen utilization from the plants does not exceed 50-60%.
The compounds of Nitrogenous fertilizers undergo a series of transformations within the soil.
Ureic Nitrogen is transformed to Ammoniac Nitrogen via hydrolysis, whilst large quantities of Ammonia gas are released to the atmosphere.
Ammoniac Nitrogen in its turn, under the effect of nitrifying bacteria or soil bacteria, is initially oxidized to Nitrite and subsequently to Nitrate salts.
Due to the high mobility of Nitrate salts, in lightweight soil they are drifted away by soil water to the deeper layers, while in heavy saturated soil they form volatile compounds, thereby increasing the losses. Because of these transformations, during the fertilization of cultures with traditional fertilizers, a part of the fertilizer is lost and rendered non utilizable by the plants.
The plants absorb Ammoniac Nitrogen (ΝΗ4-Ν) and Nitric Nitrogen (ΝΟ3-Ν).
The plants absorb soil Nitrogen in both Nitrate and Ammoniac forms.
Ammoniac Nitrogen forms stable bonds with the soil and is engaged by the roots of plants whilst they are being developed and come in contact with the soil particles. Nitric Nitrogen moves freely inside the soil and its uptake from the plants is facilitated via soil water.
